A comparison of the cost of each for 100 g indicates that the standard which costs about $1.13 per 100 grams is more expensive than the supersize which costs about $0.69 per 100 g and the supersize is more expensive than the economy which costs $0.575 per 100 g.
The cost per 100 g the standard is more than the cost per 100 g of the supersizeThe cost per 100 g of the supersize is more than the cost of the economy brand per 100 grams.The order of the cost of the brands from cheapest to most expensive can be presented as follows;
Supersize > Economy > StandardWhat is a cost per unit?The cost per unit is the cost of a number of items, divided by the number of units of the item.
The unit cost of the brands of cereal sold at the supermarket are therefore;
Unit cost per 100 gram for Standard = $2.49/220 g × 100 ≈ $1.13/g
Unit cost per gram for Economy = $5.00/725 g × 100 = $100/145/ g ≈ $0.69/g
Unit cost per gram for Supersize = $11.50/2kg × 100 = $1150/2,000 g ≈ $0.575/g
Based on the above unit cost, we get;
1.13 > 0.69 > 0.575
Therefore, the cheapest brand is the supersize with a cost per 100 gram of $0.575/g, followed by the economy, with a cost per 100 grams which is about $0.69/g then the most costly is the standard, with a cost per 100 gram of $1.13/g

State the number of complex zeros and the possible rational zeros for the function

The function f(x) = x² + 12x - 3 has two distinct real roots and no rational or complex roots. The possible rational roots are ±1 and ±3, but they are not actual roots of the equation.
To find the number of complex zeros and possible rational zeros of the function f(x) = x² + 12x - 3 = 0, we can use the same methods as in the previous question.
According to the rational root theorem, any rational root of the polynomial must be of the form p/q, where p is a factor of the constant term (-3) and q is a factor of the leading coefficient (1). The possible rational roots are therefore ±1, ±3.
To determine if there are any complex roots, we can use the quadratic formula. The solutions to the equation f(x) = 0 are given by
x = (-b ± √(b² - 4ac)) / 2a
Plugging in the coefficients of the polynomial, we get
x = (-12 ± √(12² - 4(1)(-3))) / 2(1)
x = (-12 ± √(156)) / 2
x = -6 ± 3√(13)
Since the discriminant (b² - 4ac) is positive, the square root is real, and the roots are two distinct real numbers. Therefore, there are no complex roots.
The possible rational roots we found earlier, ±1 and ±3, are not actual roots of the equation, since plugging them into the equation does not give us zero. Therefore, there are no rational roots either.
In conclusion, the equation f(x) = x² + 12x - 3 = 0 has two distinct real roots and no complex or rational roots.

The critical point (180, 120) will yield a maximum revenue of 23,700. So, the correct answer is the (180, 120).
To determine which critical point will yield a maximum revenue, we need to evaluate the objective function at each point and compare the results.
Objective Function: Revenue = 75x + 85y
1. Point (0,0):
Revenue = 75(0) + 85(0) = 0
2. Point (180, 120):
Revenue = 75(180) + 85(120) = 13500 + 10200 = 23700
3. Point (300,0):
Revenue = 75(300) + 85(0) = 22500 + 0 = 22500
Comparing the revenues at each point:
(0,0) - Revenue = 0
(180, 120) - Revenue = 23700
(300,0) - Revenue = 22500

If y, p and q vary jointly and p is 14 when y and q are equal to 2, determine q when p and y are equal to 7
In the given question, if y, p and q vary jointly and p is 14 when y and q are equal to 2 and p and y are equal to 7, we get q is equal to 14 using the joint variation formula.
To solve this problem, we need to use the formula for joint variation, which states that y, p, and q vary jointly if there exists a constant k such that ypk = kq.
In this case, we know that when y=2 and q=2, p=14. So we can set up the equation: 2*14*k = 2kq
Simplifying this, we get: 28k = 2kq
Dividing both sides by 2k, we get: 14 = q
So when p=7 and y=7, we can use the same equation: 7*14*k = 7kq
Simplifying this, we get: 98k = 7kq
Dividing both sides by 7k, we get: q = 14
Therefore, when p and y are equal to 7, q is equal to 14.

Mabel saved up her money and bought a model train. Each of the 8 cars on the train was the same length. When Mabel put all the cars together, the train was 3 feet long. How long was each car?
Each car on Mabel's train is a little less than half a foot long i.e., 3/8 feet long, or 0.375 feet long. This is solved by using simple mathematical operations.
To find the length of each car on Mabel's train, we can use the formula:
Total length of train = length of one car × number of cars
We are given that Mabel's train has 8 cars and is 3 feet long, so we can substitute those values into the formula and solve for the length of one car:
3 = x × 8
where x is the length of one car.
To solve for x, we can divide both sides by 8:
3/8 = x
Therefore, each car on Mabel's train is 3/8 feet long, or 0.375 feet long.
In other words, each car is a little less than half a foot long.
To help visualize this, imagine dividing the 3-foot length of the train into 8 equal parts. Each part would be 3/8 feet long, which is the length of one car. So when Mabel puts all 8 cars together, they form a train that is 3 feet long.

Use the differential dz to approximate the change that will be
observed in z = f (x, y) = 5/x^2 + y^2 as x changes from −1 to
−0.93 and y changes from 2 to 1.94.
To approximate the change in z = f(x, y) as x changes from −1 to −0.93 and y changes from 2 to 1.94, we can use the differential dz.
First, we need to find the partial derivatives of f with respect to x and y:
∂f/∂x = -10/x³(y²)
∂f/∂y = -10(x²)/y³
Then, we can use the following formula:
dz ≈ ∂f/∂x * Δx + ∂f/∂y * Δy
where Δx and Δy are the changes in x and y, respectively.
Substituting in the given values, we have:
Δx = -0.93 - (-1) = 0.07
Δy = 1.94 - 2 = -0.06
Using the partial derivatives we calculated earlier, we get:
dz ≈ (-10/-1.037³(2²)) * 0.07 + (-10((-1)²)/1.94³) * (-0.06)
dz ≈ -0.031
Therefore, the approximate change observed in z as x changes from −1 to −0.93 and y changes from 2 to 1.94 is -0.031.
To approximate the change in z using the differential dz, we first need to find the partial derivatives of z with respect to x and y. Given z = f(x, y) = 5/(x² + y²):
∂z/∂x = -10x/(x² + y²)²
∂z/∂y = -10y/(x² + y²)²
Now, we need to find the differential dz:
dz = (∂z/∂x)dx + (∂z/∂y)dy
Since x changes from -1 to -0.93, dx = -0.93 - (-1) = 0.07. Similarly, y changes from 2 to 1.94, so dy = 1.94 - 2 = -0.06.
Now, plug in the initial values of x and y (-1, 2):
∂z/∂x = -10(-1)/((-1)² + 2²)² = -10/25
∂z/∂y = -10(2)/((-1)² + 2²)² = -40/25
Now, plug in dx and dy into the dz equation:
dz = (-10/25)(0.07) + (-40/25)(-0.06) = 0.28 - 0.096 = 0.184
So, the approximate change in z when x changes from -1 to -0.93 and y changes from 2 to 1.94 is 0.184.

An obtuse angle is an angle that is greater than 90° but less than 180°.
We can see that the first shape has 2 angles that are greater than 90°, making this a correct choice.
The second shape has 4 boxes, meaning the angles are exactly 90°, making this incorrect.
The third shape has 6 angles that are greater than 90°, making this another correct choice.
The last shape has all 3 angles under 90°, making this also incorrect.
So, the 1st and 3rd shapes are correct.
Hope this helps! :)
And 7/8 hours Greg reads 2/3 chapters. What is the unit rate in chapters per hour? Write your answer in simplest form
The unit rate for chapters per hour is calculated as 16/21
How to find the unit rateIn order to find the unit rate for the number of chapters Gregory reads in an hour, we must firstly divide the total amount of chapters read by the amount of hours devoted to the activity:
= 2/3 chapters ÷ 7/8 hours
= 2/3 chapters × 8/7 hours
= 16/21 chapters per hour
Consequently, the unit rate for chapters per hour is calculated as 16/21, which already exists in its most simplified form.

If KJ=10, find the length of arc HJ
Answer:
Step-by-step explanation:
The arc length formula is
[tex]L=\frac{\theta}{360}*2\pi r[/tex]
Theta is the angle that intersects arc HJ. That measure is 180-122 which is 58 degrees. We put that into the formula along with the radius measure of 10 to get:
[tex]L=\frac{58}{360}*2\pi (10)[/tex] which gives us, rounded to the nearest hundredth,
L = 10.12 units
The table shows the number of turkey and ham sandwiches sold by Derby’s Deli for several days in one week Sandwiches Sold at Derby’s Deli Day Turkey Ham Monday 7 9 Tuesday 13 11 Wednesday 8 8 Thursday 15 6 Friday 12 16 What is the difference between the median number of turkey sandwiches sold and the median number of ham sandwiches sold?
The difference between the median number of turkey sandwiches sold and the median number of ham sandwiches sold is 3.
First, let's find the median number of turkey and ham sandwiches sold.
To find the median:
1. Arrange the data in ascending order.
2. If there's an odd number of data points, the median is the middle value. If there's an even number of data points, the median is the average of the two middle values.
Turkey sandwiches sold: 7, 8, 12, 13, 15
Ham sandwiches sold: 6, 8, 9, 11, 16
Now let's find the medians:
Turkey median: There are 5 data points, which is odd, so the median is the middle value, 12.
Ham median: There are 5 data points, which is odd, so the median is the middle value, 9.
Finally, let's find the difference between the medians:
Difference = Turkey median - Ham median
Difference = 12 - 9
Difference = 3

Sylvia’s car trunk measures 4.25 ft wide by 4 ft deep and 4 1 thirdft high. she has cubic boxes 16 inches wide and smaller rectangular boxes 3 inches wide by 6 inches long and 4 inches high. she has to get as many of the large boxes into her trunk as she can, and after that, she can fill the space up with the smaller boxes. how many large and small boxes can she fit into her trunk?
Sylvia can fit 9 large cubic boxes and 240 small rectangular boxes into her car trunk.
How many boxes can fit in Sylvia's car trunk?We first need to convert all measurements to the same unit. Since the large cubic boxes are given in inches, we need to convert the dimensions of the trunk to inches as well.
The trunk measures 51 inches wide (4.25 ft x 12 in/ft), 48 inches deep (4 ft x 12 in/ft), and 53.33 inches high (4*1/3 ft x 12 in/ft).
Next, we need to determine how many large boxes can fit in the trunk. Since each large box is 16 inches wide,
we can fit 3 boxes across the width of the trunk:
(51 inches ÷ 16 inches = 3.19)
Similarly, we can fit 3 boxes deep and 3 boxes high.
Therefore, the maximum number of large boxes Sylvia can fit in her trunk is:
27 (3 x 3 x 3 = 27)
After fitting as many large boxes as possible, we can calculate the remaining volume of the trunk and use this to determine how many small boxes can fit.
The remaining volume is approximately 59,712 cubic inches (51 in x 48 in x 20 in).
Dividing this by the volume of each small box:
(3 in x 6 in x 4 in = 72 cubic inches)
We can fit 829 small boxes in the remaining space.
Therefore, Sylvia can fit a total of 27 large boxes and 829 small boxes in her trunk.
