400 = 8x * x

400 = 8x^2

400 / 8 = x^2

root/50 = x

7.1cm = x

Consider that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. If 1 ounce of cottage cheese is equivalent to 2

VikaD [51]

Answer:

4.42 ounces.

Step-by-step explanation:

We have been given that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. 1 ounce of cottage cheese is equivalent to 28.35 grams. We are asked to find the ounces in 1/2 cup serving.

We will use proportions to solve our given problem.

$\frac{\text{Ounce}}{\text{Grams}}=\frac{1}{28.25}$

Upon substituting our given values, we will get:

$\frac{\text{Ounce}}{125}=\frac{1}{28.25}$

$\frac{\text{Ounce}}{125}\times 125=\frac{1}{28.25}\times 125$

$\text{Ounce}=4.42477876$

Upon rounding to nearest hundredth, we will get:

$\text{Ounce}\approx 4.42$

Therefore, 1/2 cup serving contains 4.42 ounces.

State the equation of the line in y = mx + b form.

gtnhenbr [62]

Your slope is wrong! Your slope is going to be 3/2, or C for the first problem. Your y intercept is wrong! Your Y- intercept is actually (0, -1.3) or B for the second problem.
Your equation is going to be
y= 3/2x-1.3
