The first one is incorrect because would be 4,836,000 instead of 4,836,000,000. The correct notion would be 
Answer: (8a^3x^3)/81
Step-by-step explanation: Simplifying the expression :)
Answer:
<u>Surface area = the sum of the area of all six sides:</u>
(11 · 10) + (11 · 10) + (11 · 8) + (11 · 8) + (8 · 10) + (8 · 10)
= 110 + 110 + 88 + 88 + 80 + 80
= 220 + 176 + 160
= 556 ft²

Answer:
<em>Their total sales (revenue) when they break-even is $250,000</em>
Step-by-step explanation:
<u>Linear Modeling</u>
Some situations can be mathematically represented as linear functions. If we are in a situation where a linear model is suitable, then we need two independent data to build it up.
The linear function can be expressed in the slope-intercept format:
y = mx + b
Where m and b are constant values.
The total cost function for Rally Co.'s to produce x toy trucks is:
C(x) = 200,000 + 4x
Given they sell each truck for $20, the revenue function is:
R(x)= 20x
The break-even condition is when the costs and the revenue are equal:
20x = 200,000 + 4x
Subtracting 4x:
16x = 200,000
Dividing by 16:
x = 200,000/16
x = 12,500 toy trucks
The revenue at this production level is:
R(x)= 20*12,500=250,000
Their total sales (revenue) when they break-even is $250,000
