Answer:
StIf the area of the map is 21 and the scale factor is 5:1, both of the dimensions of the flat park are multiplied by 5. If both dimensions are multiplied by 5, then the area is multiplied by (5*5)=25 times. 25*21=525.ep-by-step explanation:
I believe it is c because it is definitly not biased because they were selected at random. And d. Is incorrect
Y= 7.75x because 31/4 = 7.75 and 54.25/7= 7.75 so the amount he charges per hour is $7.75
The sum of the first 14 terms of the finite geometric series 0.5+ (-1) +2+... is -2730.5
<h3>How to determine the sum of the series?</h3>
The series is given as:
0.5+ (-1) +2+...
The above series is a geometric series, with the following parameters:
- First term, a = 0.5
- Common ratio, r = -2
- Number of terms, n = 14
The sum of the first 14 terms is calculated using:
So, we have:
Evaluate
Hence, the sum of the series is -2730.5

Answer:
x = -36
Step-by-step explanation:
Add 12 to both sides
x - 12 + 12 = x
(12 cancels out)
-48 + 12 = -36
x = -36
