Convert from mixed number to decimal number. To do it, divide the numerator of the fraction by the denominator and add the result to the whole number part. Then:

$3\frac{3}{4}\ lb=(3+0.75)\ lb=3.75\ lb$

Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:

$\frac{5}{8}lb=0.625\ lb$

Let be "x" the number of bricks in the bag.

Based on the information given in the exercise, you can set up the following proportion:

$\frac{1}{0.625}=\frac{x}{3.75}$

Finally, you must solve for "x" in order to find its value. This is:

$(3.75)(\frac{1}{0.625})=x\\\\x=6$

Why are the solutions to the proportions 50/x =10/20 and 10/50=20/x the same

ratelena [41]

With cross multiplication you can find that they are the same. In both equations, x would be 100.

What is the surface area of a square prism with sides that measure 8 units?

V125BC [204]

Answer:

The surface area of square prism = 384 units squared

Step-by-step explanation:

Explanation:-

Given the square prism side 'a' = 8 units

The surface area of square prism = 2 a² + 4 a h

Given square prism length , width and height also equal identical sides

The surface area of square prism = 2 a² + 4 a h

= 2(8)² + 4 (8)(8)

= 2(64) + 4(64)

= 384 units squared

Final answer:-

The surface area of square prism = 384 units squared
