how much soda do you need if you buy 20 bags of 4 bags of hot chips and 3 bottles of soda.

Answers

Answer 1

If each bag of hot chips requires around 500 ml of soda to drink with, then 46,000 ml of soda would be needed to buy 20 bags of 4 bags of hot chips and 3 bottles of soda.

To determine how much soda is needed if you buy 20 bags of 4 bags of hot chips and 3 bottles of soda, we need to know the volume of each bottle of soda.

Assuming each bottle of soda contains 2 liters of soda, the total volume of soda needed can be calculated as follows:

One bag of hot chips contains 4 bags of chips.So, 20 bags of hot chips contain 20 x 4 = 80 bags of chips.Each bag of chips may require around 500 ml of soda to drink with.Therefore, the total soda needed for all bags of chips is 80 x 500 ml = 40,000 ml.Three bottles of soda are also purchased, which contain a total of 3 x 2000 ml = 6000 ml.The total soda needed is the sum of the soda needed for the chips and the soda purchased, which is 40,000 ml + 6000 ml = 46,000 ml.

A:Kika; $300


B:Kika; $700


C:Mato; $700


D:Mato; $300

Answers

Mato will pay about $700 more in interest than Kika ($625 - $1,300 = $675, which rounds to $700). The answer is C: Mato; $700

Mato will pay more in interest because he has a higher interest rate and a shorter repayment period. To calculate the amount of interest each will pay, we can use the formula:

Interest = (Loan amount) x (Interest rate) x (Time in years)

For Kika:
Interest = $5,000 x 0.052 x 5
Interest = $1,300

For Mato:
Interest = $5,000 x 0.075 x (2/12)
Interest = $625

Therefore, Mato will pay about $700 more in interest than Kika ($625 - $1,300 = $675, which rounds to $700). The answer is C: Mato; $700.

D. 35,400



PLS DON'T PUT LINKS AND WRITE ANSWER, THX! I WILL MARK BRAINLIEST IF YOU WRITE THE ANSWER!

Answers

The answer is option C) 30,700

Why the answer is option C?

The problem involves using linear interpolation to estimate the population of Little Elm in 2020 based on the given data from 2010 and 2015.

To start, we need to calculate the annual growth rate of the population between 2010 and 2015. This can be done by taking the difference between the population in 2015 and the population in 2010, and then dividing that difference by the number of years in that time period:

Annual growth rate = (17,150 - 3,646) / 5 = 2,700

This means that, on average, the population of Little Elm grew by 2,700 people per year between 2010 and 2015.

Next, we can use this annual growth rate to estimate the population of Little Elm in 2020. To do this, we need to add 10 years of growth to the initial population of 3,646 (since we want to estimate the population in 2020, which is 10 years after 2010):

Estimated population in 2020 = 3,646 + (2,700 x 10) = 30,646

Therefore, the estimated population of Little Elm in 2020 is approximately 30,700, which corresponds to answer choice C.

Buy-Rite Pharmacy has purchased an auto for delivering prescriptions. The auto was purchased for $26,000, and it has a useful life of 6 years with a $5,500 salvage value. By delivering prescriptions, the pharmacy aims to increase gross revenues by at least $33,500 per year. The pharmacy will incur a cost of $28,000 per year for these prescriptions.

Using the straight-line method, the annual depreciation of the auto is ($26,000 - $5,500) / 6 = $3,917. This means that the total cost of the auto over 6 years will be $26,000 - $5,500 + ($3,917 x 6) = $43,502.

To calculate the payback period, we need to determine how long it will take for the increased gross revenues to cover the cost of the auto.

The net increase in revenues will be $33,500 - $28,000 = $5,500 per year. Therefore, the payback period is $43,502 / $5,500 = 7.9 years, which is rounded to 8 years.

Will give Brainliest! No links! Will report

Answers

Triangle PQR is not a right triangle.

To determine whether triangle PQR is a right triangle, we need to check if any of its angles is a right angle (90 degrees). We can use the slope formula to find the slopes of the sides of the triangle and check if any of the slopes are negative reciprocals (perpendicular) to each other.

Let's calculate the slopes of the sides PQ, QR, and RP:

Slope of PQ = (y₂ - y₁) / (x₂ - x₁)

= (2 - 1) / (3 - 0)

= 1 / 3

Slope of QR = (y₂ - y₁) / (x₂ - x₁)

= (-4 - 2) / (5 - 3)

= -6 / 2

= -3

Slope of RP = (y₂ - y₁) / (x₂ - x₁)

= (1 - (-4)) / (0 - 5)

= 5 / (-5)

= -1

Now, let's check if any of the slopes are negative reciprocals of each other. We can compare the products of the slopes:

Product of PQ slope and QR slope = (1/3) * (-3) = -1

Product of QR slope and RP slope = (-3) * (-1) = 3

Product of RP slope and PQ slope = (-1) * (1/3) = -1/3

Since the product of the slopes of QR and RP is not equal to -1, triangle PQR is not a right triangle.

Therefore, triangle PQR is not a right triangle.

The base of a prism is a right triangle with legs measuring 3 feet and 4 feet. If the height of the prism is 13 feet, determine its volume

Answers

The volume of the prism is 78 cubic feet.The volume of a prism is given by the formula V = Bh, where B is the area of the base and h is the height of the prism.

In this case, the base of the prism is a right triangle with legs measuring 3 feet and 4 feet, so its area is (1/2)(3)(4) = 6 square feet. The height of the prism is 13 feet. Therefore, the volume of the prism is V = Bh = (6)(13) = 78 cubic feet.To understand this calculation, think of the prism as a stack of identical, parallel cross sections. Each cross section is a copy of the base, with an area of 6 square feet.

The height of each cross section is the same, and equal to the height of the prism, which is 13 feet. To find the total volume of the prism, we add up the volumes of all these cross sections, which is equal to the area of the base times the height of the prism.

Construct angle XYZ in which XY= 8.3 cm, YZ= 11.9 cm ii, Construct M the midpoint of XZ where XYZ= 60o

Answers

To construct angle XYZ with XY = 8.3 cm and YZ = 11.9 cm, follow these steps:

1. Draw a line segment XY of length 8.3 cm.
2. At point Y, draw a ray in any direction to form an angle with XY.
3. Using a compass, draw an arc with center at point Y and radius 11.9 cm. This arc should intersect the ray drawn in step 2 at point Z.
4. Draw the line segment YZ of length 11.9 cm.
5. Using a compass, draw an arc with center at point X and radius equal to the length of segment YZ. This arc should intersect segment XY at two points. Label the point of intersection closest to Y as M.
6. Draw a line segment XM and a line segment ZM.
7. Angle XYZ is the angle formed by segments XY and YZ.

To confirm that angle XYZ is 60 degrees, we need to show that XMZ is also a 60-degree angle. Since M is the midpoint of XZ, we have:

XM = MZ

Therefore, triangles XMY and ZMY are congruent by the Side-Side-Side (SSS) criterion. Thus, angles XMY and ZMY are congruent. Since they form a straight line, we know that:

angle XMY + angle ZMY = 180 degrees

Therefore, each of these angles measures:

angle XMY = angle ZMY = 180 degrees / 2 = 90 degrees

Since angle XYZ is the sum of angles XMY and ZMY, we have:

angle XYZ = 90 degrees + 90 degrees = 180 degrees

This means that angle XYZ is a straight angle, which measures 180 degrees. However, we know that XYZ is a 60-degree angle, so we must have made an error in the construction. Double-check the construction steps to make sure that each step was performed accurately.

To find the area of sector XZY, we need to know the measure of angle XYZ. However, the given equation n/360 = 115/225 is incorrect, as it appears to be setting up a proportion between the central angle of the sector and the ratio of arc length to the circumference of the circle, rather than the ratio of the central angle to the full angle of the circle.

To find the correct measure of angle XYZ, we need to use the formula:

Area of sector XZY = (n/360) x π[tex]r^2[/tex]

where r is the radius of circle Z.

We know that the area of circle Z is 255 square feet, so we can find the radius as follows:

Area of circle Z = π[tex]r^2[/tex]

255 = π[tex]r^2[/tex]

[tex]r^2[/tex] = 81

r = 9

Now we can solve for n using the given ratio of 115/225:

n/360 = 115/225

n = (115/225) x 360

n = 184.32

Rounding to the nearest tenth, we get:

n ≈ 184.3

Finally, we can find the area of sector XZY as:

Area of sector XZY = (n/360) x π[tex]r^2[/tex]

Area of sector XZY = (184.3/360) x π[tex](9)^2[/tex]

In order to find an equation of a line which passes through point (4,7) and is parallel to line "y = 3x + 6", we use the fact that parallel lines have the same slope.

The given line ""y = 3x + 6" has a slope of 3,

Now, by using the "point-slope" form of the equation of a line, which is : y - y₁ = m(x - x₁),

where m is slope and (x₁, y₁) is a point on the line,

So, we substitute "m = 3" and (x₁, y₁) = (4,7) to get:

Answers

We get that the plane is about 2193.0 feet from the airport, Rounding to the nearest tenth

To solve the problem, we will use trigonometry and the tangent function, which relates the other facet of a right triangle to the adjoining aspect:

tan(theta) = opposite / adjacent

wherein theta is the angle of descent, opposite is the change in height, and adjacent is the space from the airplane to the airport.

Rearranging the formula, we get:

adjacent = contrary / tan(theta)

because the angle of descent is 13 ranges and the alternate in height is from 500 ft, we've got:

contrary = 500 ft

theta = 13 stages

Substituting these values into the formula, we get:

adjacent = 500 ft / tan(13 ranges)

using a calculator, we find that tan(13 stages) is about 0.228, so:

adjacent = 500 feet / 0.228 = 2192.98 feet

Therefore, we get that the plane is about 2193.0 feet from the airport.

Find the area k of the trianglea = 3, c = 2, b = 135 degrees

Answers

The area k of the triangle a = 3, c = 2, b = 135 degrees is approximately 1.06125 square units.

The area k of the triangle, we can use the formula:
k = (1/2) * b * c * sin(A)
where A is the angle opposite side a.
Find A, we can use the fact that the angles in a triangle add up to 180 degrees:
A + B + C = 180
Substituting in the given values, we get:
A + 135 + 180 = 360
A = 45 degrees
Now we can plug in all the values into the area formula:
k = (1/2) * 2 * 3 * sin(45)
k = 1.5 * 0.707
k = 1.06125
Therefore, the area k of the triangle is approximately 1.06125 square units.

A 10 ft ladder is used to scale 9 ft wall. at what angle of elevation must the ladder be situated in order to reach the top of the wall?



ps. please include an illustration/drawing of the problem. thank you!

Answers

The ladder must be situated at an angle of approximately 63.43° to reach the top of the 9 ft wall.

How to find the angle of elevation at which the ladder must be situated?

Certainly, here's an illustration of the problem:

           |\

           | \

           |   \  9 ft

           |     \

ladder |       \

  (10 ft)|_____\

      wall

To find the angle of elevation at which the ladder must be situated, we can use the trigonometric function of sine. Let θ be the angle of elevation. Then:

sin θ = opposite / hypotenuse

In this case, the opposite side is the height of the wall (9 ft), and the hypotenuse is the length of the ladder (10 ft). So:

sin θ = 9/10

Using a calculator or a trigonometric table, we can find the angle whose sine is 9/10:

θ ≈ 63.43°

Therefore, the ladder must be situated at an angle of approximately 63.43° to reach the top of the 9 ft wall.

A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study have their blood pressure taken at the beginning of the study. After being on the medication for 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test.




Change: Final Blood Pressure - Initial Blood Pressure




The researcher wants to know if there is evidence that the drug affects blood pressure. At the end of 4 weeks, 36 subjects in the study had an average change in blood pressure of 2. 4 with a standard deviation of 4. 5.




Find the



p



-value for the hypothesis test

Answers

The p-value for the hypothesis test is 0.04. This means that if the null hypothesis is true

To find the p-value, we need to conduct a hypothesis test.

The null hypothesis is that there is no difference in blood pressure before and after taking the medication:

H0: μd = 0

The alternative hypothesis is that there is a difference in blood pressure before and after taking the medication:

Ha: μd ≠ 0

where μd is the population mean difference in blood pressure before and after taking the medication.

We are given that the sample size is n = 36, the sample mean difference is ¯d = 2.4, and the sample standard deviation is s = 4.5.

We can calculate the t-statistic as:

t = (¯d - 0) / (s / sqrt(n)) = (2.4 - 0) / (4.5 / sqrt(36)) = 2.13

Using a t-distribution table with 35 degrees of freedom (df = n - 1), we find that the two-tailed p-value for t = 2.13 is approximately 0.04.

Therefore, the p-value for the hypothesis test is 0.04. This means that if the null hypothesis is true (i.e., if there is really no difference in blood pressure before and after taking the medication), there is a 4% chance of observing a sample mean difference as extreme or more extreme than 2.4. Since this p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence that the drug affects blood pressure.

TRUE or FALSE:


1. Each exterior angle of a regular hexagon is acute


2. The sum of the interior angles of a polygon is not necessarily a multiple of 180


3. In any polygon, the larger the number of vertices, the smaller the measure of an exterior angle

Answers

1. The statement "Each exterior angle of a regular hexagon is acute" is True.

2. The statement "The sum of the interior angles of a polygon is always a multiple of 180" is False.

3. The statement "In any polygon, the larger the number of vertices, the smaller the measure of an exterior angle" is True.

1. TRUE: Each exterior angle of a regular hexagon is acute.
A regular hexagon has six equal sides and six equal interior angles. The sum of the interior angles of a hexagon is (6-2) * 180 = 720 degrees. Since it's a regular hexagon, each interior angle is 720/6 = 120 degrees. The exterior angles are supplementary to the interior angles, so each exterior angle is 180 - 120 = 60 degrees. Since 60 degrees is less than 90 degrees, each exterior angle is acute.

2. FALSE: The sum of the interior angles of a polygon is always a multiple of 180.
The formula for the sum of the interior angles of a polygon is (n-2) * 180, where n is the number of vertices (or sides). As you can see, the result is always a multiple of 180.

3. TRUE: In any polygon, the larger the number of vertices, the smaller the measure of an exterior angle.
For a regular polygon, the measure of an exterior angle can be calculated as 360/n, where n is the number of vertices (or sides). As the number of vertices increases, the measure of an exterior angle decreases, since they are inversely proportional.

How many sides does a regular n-gon have if one interior angle measures 150°? Show all work!

Answers

Answer:

A regular n-gon with one interior angle of 150° has 12 sides.

Step-by-step explanation:

The formula for the measure of each interior angle of a regular n-gon is:

180(n-2)/n

where:

n is the number of sides

We are given that one interior angle measures 150°, so we can set up the equation:

180(n-2)/n = 150

Multiplying both sides by n, we get:

180(n-2) = 150n

Distributing, we get:

180n - 360 = 150n

Subtracting 150n from both sides, we get:

30n - 360 = 0

Adding 360 to both sides, we get:

30n = 360

Dividing both sides by 30, we get:

n = 12

Therefore, a regular n-gon with one interior angle of 150° has 12 sides.

How do I do this step by step

Answers

Answer:

Step-by-step explanation:

Let's call the total volume of the container "V".

We know that the container was originally 15% full, so the amount of water in the container was 0.15V.

When 48 litres of water was added, the new volume of water in the container became 0.15V + 48.

We also know that the container is now 75% full, so the new volume of water in the container must be 0.75V.

We can set up an equation to solve for V:

0.15V + 48 = 0.75V

Subtracting 0.15V from both sides:

48 = 0.6V

Dividing both sides by 0.6:

V = 80

So the container can hold 80 litres of water when it is full.
