John needs to paint one wall in his school. He knows that 1 can of paint covers an area of 24 square feet. John uses a meter sti

laila [671]

The complete question in the attached figure

step 1
find the area of the wall

[area of the wall]=[area of rectangle]+[area of triangle]
[area of the wall]=[3*2]+[3*1/2]----> 7.5 m²

1 m²-------> 10.7639 ft²

area of the wall------> 7.5*10.7639------> 80.73 ft²

we know that
1 can of paint covers an area of --------> 24 ft²
x---------------------------------------------> 80.73 ft²
x=80.73/24---------> x=3.36 can of paints

the answer is
T<span>he fewest number of cans is 4</span>

For each expression,use a property to write an equivalent expression.Tell which property you used. 10:CD= 11:x+13= 12:4(2x-3)= 1

stellarik [79]

10.) DC
community property

11.) 13+x
community property

12.) 8x-12
distributive property

13.) (2+a)+b

14.) 4(2x+1)= 4+8x

For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)

1. A college newspaper, The College Spy, has a fixed production cost of $70 per edition and it costs 40¢ per copy to print and d

Mars2501 [29]

a. What is the cost expression for the newspaper?

The cost would be the sum of fixed cost and the variable cost. The fixed cost is 70 while the variable cost is 0.40 x, where x stands for the number of copies made. That is:

Cost = 70 + 0.40 x

where x = number of copies made

b. What is the revenue expression for the newspaper?

The revenue would simply be the product of selling price and number of copies sold or made, that is:

Revenue = 0.50 x

c. Put the cost and revenue expressions into an inequality that would represent a successful newspaper.

To have a successful newspaper, the difference of revenue and cost must be greater than 0, that is:

Revenue – Cost > 0

0.50 x – (70 + 0.40 x) > 0

d. How many copies should be sold to make a profit? Show all work! An answer with no work will receive 0 points.

From the above equation, we solve for x.

0.50 x – (70 + 0.40 x) > 0

0.50 x – 70 – 0.40 x > 0

0.10 x > 70

x > 700

Number of copies made should be more than 700 copies

e. Now go back to your answer for d. On every line of your solution write what property of math you would use to justify the transformation that occurred.

0.50 x – (70 + 0.40 x) > 0 Distribution property

0.50 x – 70 – 0.40 x > 0 Addition property

0.10 x > 70 Addition property

x > 700 Division property

An executive invests $26,000, some at 8% and some at 6% annual interest. If he receives an annual return of $1,860, how much is

S_A_V [24]

Let x = amount invested at 8%
26000 - x = amount invested at 6%

0.08x + 0.06(26000 - x) = 1860

solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000
