Food A contains 150 calories in 3/4 of a serving.

Food B. Contains 259 calories in 2/3 of a serving.

Find each unit rate. Which food has a fewer calories per serving

Please HELP MEE :((

Food B has fewer calories.

Step-by-step explanation:

To find the unit rate we had to transfer both to have the denominator. To do that we have to find a common denominator both 4 and 3 have. The common denominator is 12. We then use 12 as a denominator and solve. (Sorry I don't really know how to explain.)

Food A=

12 ÷ 4 is 3, 3 × 3  = 9.

9/12

Food B=

12 ÷ 3 = 4, 4 × 2 = 8.

8/12

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
