Answer:
3610 dollars
Step-by-step explanation:
Remark
If you take the Cube Root of the volume, that will give you the length of an edge of the cube. If you square the edge, you get the area of one of the faces of the cube.
The Cost = the Area of 1 face * 10 dollars. is the answer.
Given
Volume = 6859 cubic feet
Cost per square foot = 10 dollars.
Solution
V = 6859 feet^3 Take the cube root of both sides
Edge = ∛V
Edge = ∛V = ∛6859
Edge = 19 feet exactly.
Area of the floor = s^2
Area of the floor = 19^2
Area of the floor = 361 square feet
Cost = 10 * 361 = $3610
Answer:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Answer:
You make $32,000 a year and want to save 10% of your income every year. How much should you put into savings every month?
$32$,000 x 0.10 = 3,200
You want to save $3200 a year.
You should be saving $266.67 a month or $133.33 a paycheck if you are paid

Answer:
The figure is attached down
Step-by-step explanation:
To graph a line you must have its equation
The form of the linear equation is y = m x + b, where
- m is its slope
- b is the y-intercept (y at x = 0)
∵ The slope of the line is 
∴ y = x + b
- To find b substitute x and y in the equation by the coordinates
of a point on the line
∵ The line passing through point (-5 , -4)
∴ x = -5 and y = -4
∵ -4 = (-5) + b
∴ -4 = 
+ b
- Subtract from both sides
∴ 
= b
∴ y = x - 
To draw the line substitute x by any two values and find their ys
∵ x = -2
∴ y = (-2) -
∴ y = -6
∴ The line passing through point (-2 , -6)
∵ x = 1
∴ y = (1) -
∴ y = -8
∴ The line passing through point (1 , -8)
∵ x = 4
∴ y = (4) -
∴ y = -10
∴ The line passing through point (4 , -10)
Now we can make a table to draw the line
→ x : -5 : -2 : 1 : 4
→ y : -4 : -6 : -8 : -10
Plot the points on the graph paper and draw the line

The percentage of consignors who receive a check for more than $370 is:
= 16%.
Step-by-step explanation:
Mean of consignor check, μ = $480
Standard deviation, σ = $110
Value of check received, x > $370
Solution: find the z-score to determine the percentage of consignors who receive a check for more than $370:
z = (x-μ)/σ
z= ($370 - $480)/$110
z = -$110/$110
z = -1.00
Percentage of consignors who receive a check for more than $370
= 0.15866
= 0.16
= 16%
