Answer:
80 students
Step-by-step explanation:
52 + 28 = 80
Answer:
The original area would be multiplied by the scale factor of 2² to get the new area.
Step-by-step explanation:
If you double the radius lets so lets do an example
(a=πr²) so
if x is the radius the area would be x²π
double the radius so 2x then the area would be
(2x)²π so 4x²π
4x²π/x²π= 4 so its 4 times greater or
D the last answer or The original area would be multiplied by the scale factor of 2² to get the new area.
Answer:
`Part A:
D. 3/4(18 + s) = 31.50
Part B:
$36
Step-by-step explanation:
I think 34 is 3/4, is that right?
here, s is the cost of the skirt
Part A: The answer would be:
3/4(18) + 3/4(s) = 31.5 =
3/4(18 + s) = 31.5
Part B: 3/4(18) + 3/4(s) = 31.5
4.5 + 3/4s = 31.5
Subtract 4.5 from both sides:
3/4s = 27, 27 is the cost of the skirt now, but we need the original price.
multiply both sides by 4/3:
s = 36
