<h3>Answer:</h3>
A. 5/4 . . . or . . . 1.25
B. see below
<h3>Explanation:</h3>
B. The dilation factor is the ratio of the image lengths to the original lengths. Here, for example, that could be
... d = E'F'/EF = (-4-(-9))/(-2-(-6))
... d = 5/4
A. The result of the calculation of part B is 5/4 = 1.25.
Answer:
Real fifth root of 1024 is 4.
Step-by-step explanation:
We have to find the value of real fifth root of 1024.

Therefore 
Or 
Therefore x = 4
X= 4 is the right answer.
(4) 64 tiles, (5) 
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft
= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 
So, the expression is .
(6) The equivalent expression is 
.
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
