Answer:

x = 10

Step-by-step explanation:

Given

AB = 8

AC = x

QR = 12

QS = 15

Required

Find x

Because both triangles are similar, we have:

AB : AC = QR : QS --- Equivalent ratios

This gives:

8 : x = 12 : 15

Convert to fraction

\frac{8}{x} = \frac{12}{15}

Cross Multiply:

12 * x = 8* 15

12x = 120

Divide both sides by 12

x = \frac{120}{12}

x = 10

a cardboard box holds 31.25 cubic inches of creamy butter. The butter is molded into a square prism that is 5 inches long. How m
lesya [120]

Answer:

62.5 \:in^2

Step-by-step explanation:

Volume of the butter in the cardboard = 31.25 cubic inches

Length of the Molded Square Prism =5 Inches

Let the length of the square cross sectional area = x

Volume of the Prism=x^2l

Since l=5 Inches

5x^2=31.25\\x^2=6.25\\x=2.5\: Inches

Next, we determine the surface area of the New Cardboard box to be made.

Length of the Cardboard Box=5 Inches

Length of the square cross sectional area = 2.5 Inches

Total Surface Area=2(x^2+xl+xl)=2(x^2+2xl)

=2(2.5^2+2(2.5)(5))\\=2(6.25+25)\\=2*31.25\\=62.5 \:in^2

Therefore, 62.5 \:in^2 of cardboard is needed,
