Answer:</h2>
for 1 candle: 150.72
for 130 candles: 19,593.6
<h3 /><h3>
Step-by-step explanation:</h3>
the formula for finding the volume for a cylinder is:
V = π r ² × h
when you plug it in:
V = 3.14 (4) ² × (3)
V = 150.72
150.72 × 130 = 19,593.6
Hope this helps! (:

Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
<h3>Answer:</h3>
Length: 12 yd
Width: 5.5 yd
<h3>Explanation:</h3>
Let x represent the width of the rectangle in yards. Then 2x+1 can represent the length (double the width plus 1 yard). The area is the product of length and width so we have the relation ...
... x(2x+1) = 66
... 2x² +x -66 = 0
This can be solved using any of several methods. One of them is to factor the equation. To do that, we can look for factors of 2·66 = 132 that differ by 1. Since 132 = 11·12, those are the numbers we're looking for. Then ...
... 2x² +12x -11x -66 = 0 . . . . use our found numbers to rewrite the x term
... 2x(x +6) -11(x +6) = 0 . . . . .factor by grouping
... (2x -11)(x +6) = 0
... x = 11/2 or -6 . . . . . values that make the factors zero. Only the positive value is a useful solution.
... The width of the rectangle is 5.5 yards. Its length is 2·5.5+1 = 12 yards,
Answer:
184
Step-by-step explanation:
The prime numbers between 40 and 56 are 41, 43, 47, and 53.
Add the prime numbers.
41 + 43 + 47 + 53
= 184
