<u>Part a)</u>
Given the expression
Apply exponent rule: 
∵ 
Rewrite 81 as 3 · 27
Rewrite 54 as 2 · 27
Factor out the common term: 27m³n
Therefore,
<u>Part B)</u>
Given the expression
Apply exponent rule:
Rewrite as
Factor out common term 5y²x²z
Therefore,
I'm guessing the question is meant to be "<span>If the radius of a circle with a area of 5.3 mm squared is multiplied by 5, what will the new area be?", so i'll answer that.
Area of a circle =</span>πr^2
5.3=πr^2, 5.3=π(5r)^2
132.5=25πr^2
Given:
Profit : 15,000,000
Cost: 30 per basketball hoop
production: 1 million hoops
price: 50 - 5x²
Profit = Sales - Cost
15,000,000 = sales - 30(1,000,000)
15,000,000 + 30,000,000 = sales
45,000,000 = sales
45,000,000 / 1,000,000 = 45 sales price.
Answer:
try restart it and charge it to the max and then try change the internet source likeopen hotspot and see
The answer is d, when you divide 45 by 54 you get 0.833333333333.... the line above the 3 means that there is infinite number of threes
