Write a formula that will help james find the price per milliliter for each brand
navik [9.2K]

Answer:

z=\frac{x}{y}

Step-by-step explanation:

<u><em>The complete question is</em></u>

James has to buy juice for his class party. there are several brands of juice at the store, and each container is a different size and price. write a formula that will help James find the price per milliliter for each brand.

x=price of juice

y=number of milliliters in carton

z=price per milliliter

we know that

The price per milliliter for each brand, is the same that the unit rate

so

To find out the unit rate , divide the price of juice by the number of milliliters in carton

so

z=\frac{x}{y}

Find an angle measure of angle A and B <br> A (5y-3) <br> C (3y+27)
Mashcka [7]

The measure of angle A and C will be 94.5° and 85.5°.

<h3>How to calculate the angle?</h3>

(5y - 3) + (3y + 27) = 180

Collect like terms

5y + 3y - 3 + 27 = 180

8y = 180 - 27 + 3

8y = 156

y = 156/8 = 19.5

(5y - 3) = (5 × 19.5) - 3 = 94.5

(3y + 27) = (3 × 19.5) + 27 = 85.5

Therefore, the measure of angle A and C will be 94.5° and 85.5°.

Number 3
sdas [7]

Answer: Choice A) 1990 to 1991

=============================================

Explanation:

Let's go through the answer choices one by one.

For choice A, we go from the year 1990 to 1991 which is a change of 1 year. The wage goes from 3.80 to 4.25 over this timespan, which is an increase of 4.25-3.80 = 0.45 dollars. Divide the change in wage (0.45 dollars) over the change in change in time (1 year) to get 0.45/1 = 0.45; this indicates that the wage increased by 0.45 dollars per year over the timespan 1990 to 1991

Now onto choice B. We have a wage increase of 3.80-3.35 = 0.45 over a course of 9 years (since 1990-1981 = 9) so 0.45/9 = 0.05 is the rate of wage growth, meaning that the wage bumps up by a nickel each year. So far choice A is the winner.

Moving onto choice C, we have a wage increase of 0.25 dollars (3.35-3.10 = 0.25) over an 1 year period (1981-1980 = 1) so the rate of change for this slice of time is 0.25/1 = 0.25 dollars per year. Choice A is still the winner.

Finally, for choice D, this is over a year as well (1980-1979 = 1) and the wage increases by 0.20 dollars (3.10-2.90 = 0.20) leading to a rate of change to be 0.20/1 = 0.20

So choice A has the largest rate of change which is the same as saying it has the largest rate of wage increase. This shows why choice A is the answer.

Volgvan

Answer:

47.14 in³

Step-by-step explanation:

Here is the complete question

Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?

Volume of a cone = \frac{1}{3}πr²h

π = 22/7

Radius = diameter / 2 = 6 /2 = 3 inches

(1/3) x (3^2) x (22/7) x 5  = 47.14 in³
