Answer:

56 cent per ft²

Step-by-step explanation:

Wall dimension = 35 feets * 21.5 feets

Total cost of paint used = 421.40

Area of wall = Area of rectangle = Length * width

Area of wall = 35 feets * 21.5 feets

Area of wall = 752.5 ft²

Cost of paint per square feet:

Total coast of paint / Area of wall

$421.40 / 752.5 ft²

= $0.56 per ft²

= 0.56 * 100 = 56

Solve for x: 3-x = 3(6x-9). Describe the process used to solve the equation and show each step.
FromTheMoon [43]

Answer:

x=1.578

Step-by-step explanation:

Given equation is 3-x = 3(6x-9)

We need to find the value of x

3-x = 3(6x-9)

Distribute 3 in the right-hand side  

3-x=18x-27

Add both sides x

3-x+x=18x+x-27\\3=19x-27

Now, add both sides 27

3+27=19x-27+27\\30=19x

Divide both sides by 19

\frac{30}{19}=\frac{19x}{19}\\x=1.578

So, x=1.578

10. Is it possible to divide 15 by a mixed number and get a quotient that is greater than 15? Explain.
bazaltina [42]
Mixed numbers are greater than one. it wouldn't make sense for a mixed number to be less than one, because then it would just be a regular fraction.

you can only get a bigger number if you divide by a number less than one. that means you can't divide 15 by a mixed number and get a bigger number.

When completely filled, a spherical storage tank
mamaluj [8]

Answer:

radius: 12

Given the following:

Volume of sphere: 7,240

Formula of volume of sphere:

Volume = 4/3 π (radius)³

Find radius:

  • 4/3 π (radius)³ = 7,240

<u>change sides</u>

  • (radius)³ = 7,240/(4π/3)

<u>simplify</u>

  • (radius)³ = 1728.422682

<u>cube root on both sides</u>

  • radius = ∛1728.422682

<u>simplify</u>

  • radius = 12
