Shannon feeds her cat twice a day. In the morning, she feeds her cat one can of cat food. In the evening, she feeds her cat one

AysviL [449]

Each can of cat food holds 4 ounces.

Step-by-step explanation:

Step 1: Given that Shannon feeds her cat twice a day, morning = 1 can and evening = 1.5 cans. Total ounces the cat eats per day = 10. Form an equation out of this. Let the ounces in a can be x.

⇒ x + 1.5x = 10

⇒ 2.5x = 10

∴ x = 10/2.5 = 4 ounces

What are the values of x and y? (9x - 19y) (5x - 17) (3x + 3)º X = y =

TEA [102]

Answer: x = 10 and y = 3

Step-by-step explanation:

Due to the x rule, (5x - 17) = (3x + 3)

If we add 17 to both sides:

5x = 3x + 20

Take away 3x from both sides

2x = 20

Divide by 2:

X = 10

This means that (5x - 17) = (3x + 3) = 33

Since all angles must add to 360, the top angle = (360- (33*2)) /2

(360-66) /2

294 /2

147

This shows that 9x - 19y = 147

90 - 19y = 147

Minus 90 both sides

19y = 57

Y = 3

So, x = 10 and y = 3

The radius of Earth is about 3960 miles. The radius of the moon is about 1080 miles. a. Find the surface area of Earth and the m

Molodets [167]

A) The formula for surface area of a sphere is A = 4*PI*r^2

using 3.14 for PI:

Surface area for Earth = 4 * 3.14 x 3960^2 = 196,960,896 miles^2

Surface area of the moon: 4 * 3.14 * 1080^2 = 14,649,984 miles^2

B)Divide the Surface of the Earth by the moon:

196,960,896 / 14,649,984 = 13.44

The Earths surface is 13.4 times larger than the moon.

C) Multiply the surface of the Earth by 70%:

196,960,896 * 0.70 = 137,872,627.2 million square miles of water.
