Colt1911 [192]3 years ago
7 0

Answer:

2 OR4 ; both correct

Explanation:

x^2=7

x^4+y^2=50

x^4=(x^2)^2=(7)^2=49 --> 49+y^2=50

y^2=50-49=1 --> y=±\sqrt{1} --> y=±1

+1 or -1 both possible --> solve both

+1+w=3 --> w = 3 - 1 = 2

OR

-1+w=3 --> w = 3 + 1 = 4

Answer:

In order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of paint thinner

2.4 ounces of thinner will be required for 12 ounces of paint mixture

Therefore, in order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of thinner.

<h3>What is Unearned revenue?</h3>
