An art project has an area of 63.6 square inches. What is the width, in inches, of the project?

miss Akunina [59]

Answer:

Option C . 5.3 in

Step-by-step explanation:

The complete question is

An art project has an area of 63.6 square inches. What is the width, in inches, of the project?

A rectangle is shown divided into 4 smaller rectangles that are related to the size of the edges. The top edge is labeled 10 inches and 2 inches, above the top two rectangles. The top two rectangles are much larger than the bottom two rectangles

Let

x ----> the length of the art project in inches

y ----> the width of the art project in inches

we know that

The area of the rectangular art project is equal to

$A=xy$

we have

$A=63.6\ in^2$

$63.6=xy$ ----> equation A

$x=10+2=12\ in$

substitute the value of x in the equation A

$63.6=(12)y$

solve for y

$y=63.6/12\\y=5.3\ in$

The arithmetic mean (A) of two numbers (a and b) is given by the formula A=a+b/2, and their geometric mean (G) is given by G=√ab

Ann [662]

A = a+b / 2
G = √( a b )
G = √ ( A H ) / ² ( we will square both sides of the equation )
G² = A H
H = G² / 2
$H = \frac{G ^{2} }{A}= \frac{a b}{A}= \\ = \frac{ab}{ \frac{a+b}{2} }= \frac{2ab}{a+b}$

Sindrei [870]

2x + 7 = 12
Subtract 7
2x = 5
Divide by 2
X = 2.5

Y = -2x
Y = -2(2.5)
Y= -5

Multiply. Write answers in simplest form

egoroff_w [7]

First, change the mixed number into an improper fraction : 1 3/4 = 7/4
Then, write -7 as an improper fraction. You now have this expression:

-7/1 x 7/4.

Multiply each numerator and denominator, and you get your answer: -49/4, which reduces to -12 and 1/4, or -12.25
