Answers

Answer 1

Answer:

c

Step-by-step explanation:

30:14    The division isn’t proportional. 30/5 is 6 but 14/5 is not 4.

6.4

—————

30:14   Same here as above just now the 14 is proportional just not the 21.

21:7

—————

30:14     Finally! The 2nd ratio is twice the first!

60:28

Answer 2

Answer: hope this helps ♡

C. 60:28

Step-by-step explanation:

30:14

A. 6:4 → 30 ÷ 6 = 5 & 14 ÷ 4 = 3.5 (the answers aren't equal) 30:14 ≠ 6:4

B. 21:7 → 30 ÷ 21 = 1.4 & 14 ÷ 7 = 2 (the answers aren't equal) 30:14 ≠ 6:4

C. 60:28 → 30÷60 =0.5 & 14÷28 = 0.5 (the answers are equal) 30:14 = 60:28

A child's pool is filled to the top. On day 1, the level of the water in the pool decreases by [tex]1\frac{1}{3}[/tex] inches. On day 2, the level of the water decreases by [tex]\frac{3}{8}[/tex] inch. What number represents the total change in the water level after 2 days?
A. [tex]-1\frac{17}{24}[/tex] inches C. [tex]\frac{23}{24}[/tex] inch

B. [tex]\frac{-23}{24}[/tex] inch D. [tex]1\frac{17}{24}[/tex] inches

Answers

Answer:

[tex] \displaystyle A) -1 \frac{17}{21} [/tex]

Step-by-step explanation:

refer the attachment

the blue line refers the amount of reduction in the first day and the black line refers the amount of reduction in the second day

note that the total amount of depth of the the pool isn't specified therefore we can't assume the total depth of the pool to be 1 and as it says 'decrease' we are dealing with negative numbers

so

[tex] \rm \displaystyle \text{the level of the water in the pool decreases by $1\frac{1}{3}$ inches} \iff \boxed{- 1\frac{1}{3} }[/tex]

likewise

[tex] \rm \displaystyle \text{the level of the water in the pool decreases by $\frac{3}{8}$ inches} \iff \boxed{- \frac{3}{8} }[/tex]

since it wants the total amount of reduction we just need to add them which yields:

[tex] \displaystyle - 1 \frac{1}{3} + \bigg(- \frac{3}{8}\bigg) [/tex]

simplify complex fraction:

[tex] \displaystyle - \frac{4}{3} + \bigg(- \frac{3}{8} \bigg)[/tex]

simplify addition:

[tex] \displaystyle - \frac{41}{21} [/tex]

the option is given in complex fraction thus convert it to complex fraction:

[tex] \displaystyle -1 \frac{17}{21} [/tex]

and we're done!

hence our answer is A

Answer:

[tex]( - 1 \frac{17}{24} \: inches)[/tex]

Step-by-step explanation:

[tex]1 \frac{1}{3} + \frac{3}{8} \\ = \frac{4}{3} + \frac{3}{8} \\ = \frac{32}{24} + \frac{9}{24} \\ = \frac{41}{24} = 1\frac{17}{24} [/tex]

Question 3 (2 points) Saved Which of the following has the larger area? A rectangle with sides 12 inches and 15 inches. A triangle with a base of of 25 inches and a height of 14 inches. Question 3 options: The rectangle by 5 square inches. The triangle by 170 square inches. The rectangle by 170 square inches. The triangle by 5 square inches.

Answers

The solution is, The triangle by 170 square inches, so, the triangle has a much larger area.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

A rectangle with sides 12 inches and 15 inches.

A triangle with a base of of 25 inches and a height of 14 inches.

so, we get,

area of rectangle is,

A = length * width

so, area = 12 * 15

area of rectangle = 180

now, we know that,

area of triangle = 1/2 * base * heigth

so, area = 1/2 * 25 * 14

area of triangle = 350

so, we get,

the triangle has a much larger area.

350-180=170

the triangle by 170 square inches

Hence, The solution is, The triangle by 170 square inches, so, the triangle has a much larger area.

A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:

Answers

Answer:

The time for 22 leg-press reps is 11.9 seconds.

Step-by-step explanation:

The lines of best fit is the trend line of the dataset.

The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fit

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

(B) The number of seconds for 22 leg-press reps

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

  = 2.640 + 9.274

  = 11.914

(Approximate to the nearest hundredths)

  = 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.

Find the value of the variable.

Answers

These angles are supplementary, meaning that their sum should be 180.

Write an equation.

5x+110=180

5x+110-110=180-110

5x=70

x=14

To find the angle measure,

multiply 5 by 14.

5 x 14= 70

To check:

70+110=180

Therefore, the variable has a value of 14.

Var ‘x’ = 14.

The angle reflecting 110 degrees is also 110 degrees.
110 * 2 = 220 degrees.

Out of a 360-degree division, 360 - 220 = 140 degrees (5x degrees + it’s reflected angle.)

2(5x) = 140
10x = 140
x = 14

Jada has a monthly budget for her cell phone bill. Last month she spent 120% of her budget, and the bill was $60. What is Jada’s monthly budget? Explain or show your reasoning.

Answers

Assume that the budget is n.
Now we are given that 120% of the budget is equal to $60.
This means that:
60 = 1.2n

Solve the equation for n to know the budget:
60 = 1.2n
n = 60 / 1.2 = 50

Based on the above calculations, Jada's budget is 50$

Describe the pros and the cons of using the standard form of a line to graph an equation.

Answers

Answer:

The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.

Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.

One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

HELP ME PLEASE !!!!!!!!

Answers

Answer:

Step-by-step explanation:

To think about this logically, lets take a different, more simplified example.

Lets say we have two numbers: 4 and 6

The product of these numbers is 24. If we doubled the product, we would get 48.

Using our original equation, how could we get a result of 48? We could double either 4, or 6. 8 times 6 equals 48, and 12 times 4 equals 48.

So, from this we can take away that in an expression, doubling one number will double the answer. On a side note, you could you use this not only when doubling a number. If you tripled a number in an expression, then the answer to the expression would also triple.

So, the answer to your question is (A) - Double one dimension

=150^{2}

again,

Area of 2 st rectangle, length = 6m and breath = 4m

So using formula , rectangle = length × breadth

= 6 m × 4 m

= 24m^{2}

Now ,

Kevin hopes to earn a college basketball scholarship. To improve his shooting skills, Kevin shoots 50 baskets / day. If Kevin shoots 50 baskets every day for 60 days, how many shots will Kevin take? help please!

Answers

Answer:

Kevin will shoot 3,000 baskets in 60 days.

Explanation:

If Kevin shoots 50 baskets per day, that means the ratio of baskets shot to number of days is 50:1.

When the 1 changes to 60, you have to divide 60/1 to see how many times 1 was multiplied to get 60, then multiply the quotient by the 50.

In this case, 60/1=60. SO, we multiply 50*60 and get 3,000.
