Need help on this! Please someone help!!!

This can be easily solved, especially with a calculator.
With the calculator, you can find that $\sqrt{42}$ is about 6.4807.
Multiply that by 2, you get about 13 inches.

If you can't use a calculator, then you can just estimate. Since we know that $\sqrt{36}$ is 6 and $\sqrt{49}$ is 7, $\sqrt{42}$ is in between them, so you can just say somewhere around 6.5.

Multiply 2 * 6.5 and you get 13 inches.

Ann is going on vacation. Ann dog food for a pet sitter to feed her dog Maggie while she's away she leaves 24 cans of wet food a

docker41 [41]

1/4x = 24 for cans
Multiply both sides by 4 (the multiplicative inverse of 1/4)
x = 96 days

3/4x = 38 for dry food
Multiply both sides by 4
3x = 152
x = 50.666667

So I would say Ann can be gone 50 days before Maggie runs out of food. I don’t think they would count the 2/3 of a day. She will run out of dry food before canned food.
