Roger mixed 5/8 cup of red paint with 2/5 cup of yellow paint. How much red paint is needed (using the same ratio) if he wants t
never [62]
Set up the ratio as fractions

(5/8) cup red / (2/5) cup yellow = r amount of red / 1 cup yellow

Then cross multiply the numbers and set up as a equation like this

(5/8) × 1 = (2/5) × r

(5/8) = (2/5)r

Multiply both sides of the equation by (5/2) to get rid of the fraction and solve for r

(5/2) × (5/8) = (2/5)r × <span>(5/2)

25/16 = r

Reduce down to 5/4 or change to a mixed number

1 and 1/4  cups = r</span>

What is equivalent to 5 to the 2nd power times 5 to the 2nd power
adelina 88 [10]

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>

<h2>Explanation:</h2>

In this case, we have the following statement:

<em>5 to the 2nd power times 5 to the 2nd power. </em>In a mathematical language:

5^2\times 5^2

From product rules, we know that:

a^n \cdot a^m=a^{n+m}

Applying this rule to our problem:

5^2\times 5^2=5^{2+2}=5^4=625

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>
