Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
$15.83->$20
Have a good day.
We will take an example of a rectangle with a scale factor of enlargement by 2.
For example, consider a rectangle with dimensions of 6 cm and 3 cm.
If we increase the scale factor for the initial rectangle by 2, both sides of the rectangle will be doubled. By raising the scale factor, we mean multiplying the present rectangle measurement by the supplied scale factor. We have multiplied the original rectangle measurement by 2 here.
The rectangle's length was originally 6 cm and its width was 3 cm.
After multiplying by two, the length is 12 cm and the width is 6 cm.
Thus, we took an example of a rectangle with a scale factor of enlargement by 2. We consider this for a better understanding.

Answer: the correct answer is 7i and i square root of 49
5. c = 13
6. b=6
7. b=8
8. a=30
9. a=2√3
Step-by-step explanation:
We will use Pythagorean theorem in each to find the length of missing side.
5. a=12, b=5
Putting in formula
Taking square root on both sides
Therefore,
c = 13
6. a=8 , c=10
Putting in formula
Taking square root on both sides
b=6
7. a=15, c=17
Putting in formula
Taking square root on both sides
b=8
8. b=40, c=50
Putting in formula
Taking square root on both sides
a=30
9. b=2 , c=4
Putting in formula
Taking square root on both sides
a=2√3
