Haley bought a 3 pound bag of cat food she feeds her cat 6 ounces of cat food each day with a bag of cat food be enough to feed her cat for seven days

a -pound bag of cat food can enough to feed her cat for 7 days

Step-by-step explanation:

Given:

3-pound bag of cat food

6 ounces of cat used per day

Number of cat food used in 7 days (in ounces): 7*6 = 42 ounces

As we know,1 pound (lb) is equal to 16 Ounces (oz)

<=> 42 ounces = 42 /16 = 2.625 pounds < 3-pound bag

So a -pound bag of cat food can enough to feed her cat for 7 days

Hope it will find you well.

(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

i think the answer is true
