Answer:
there is no question.
Step-by-step explanation:
To be divisible by 63, it must be divisible by both 7 and 9, since 7x9 = 63. Factor the expression, simplify, and see if both 7 and 9 are factors, which would make it divisible by both 7 and 9. (163 - 83)(43 + 23) = [(24)3 - (23)3] [(22)3 + 23] = (212 - 29)(26 + 23) = [29(23 - 1)] [23(23 + 1)] = [29(8 - 1)] [23(8 + 1)] = 29(7) 23 (9) = 63(212) It is a multiple of 63, and hence divisible by 63.
Answer:
<u>The correct answer is A. The cost of pizza in dollars per square inch</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Cost of the pizza = $ 0.10 * π * r², where r = radius of the pizza in inches
2. What does the constant 0.10 in the function represent?
Let's recall the formula of the area of a circle, in this case, the area of the pizza:
Area = π * r², therefore the constant 0.10 that is multiplying the area of the pizza, is the cost of the pizza in dollars per square inch and the total cost is the result of the multiplication of the area by 0.10.
<u>The correct answer is A. The cost of pizza in dollars per square inch</u>
I think it would go under equilateral..
To find the number of CD on sale, we can set an equation.
Let y be the number if CD.
As she bought 40%, the amount she bought= 40%y
The equation:
40%y = 80
0.4y = 80
y = 80÷0.4
y=320
Therefore there were originally 320 CDs.
Hope it helps!
