Answer:

5×10⁻²

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point.
The number of decimal places you move will be the exponent on the 10. a. If the decimal is being moved to the right, the exponent will be negative.

b. If the decimal is being moved to the left, the exponent will be positive.

Therefore. The answer is 5×10⁻²

You are purchasing books summer reading for $4.50 each. Part A: Your total cost, C, depends on,The input is,and the output is,Pa

Crazy boy [7]

Answer:

Part A) see the explanation

Part B) $C(12)=\$54$

Step-by-step explanation:

Part A)

we know that

A relationship between two variables, x, and C, represent a proportional variation if it can be expressed in the form $k=\frac{C}{x}$ or $C=kx$

Let

C ---> is the total cost (represent the output or dependent variable)

x ----> is the number of books (represent the input or independent variable)

In this problem

we have a proportional relationship between the variables x and C

Part B) we know that

The linear equation is given by

$C=kx$

The constant of proportionality k is the same that the slope or unit rate of the linear equation

In this problem the constant k is given

$k=\$4.50\ per\ book$

so

$C=4.50x$

For x=12 books

substitute in the equation and solve for C

$C=4.50(12)=\$54$

In function notation

$C(12)=\$54$

Answer:

304

Step-by-step explanation:

find the area of each side, then add together

top and bottom are 10*8= 80 80*2= 160

front and back are 10*4=40 40*2=80

left and right sides are 8*4=32 32*2=64

160+80+64=304
