700cm
Step-by-step explanation:
use basic proportion;
if scale = 1 : 100
then 7 : ?more
so 7/1 x 100 = 700cm
Perimeter P=2L+2W
P=24
L=w+4
P=2(w+4)+2w
24=2w+8+2w
24=8+4w
16=4w
w=4
L=8
Answer:
50 employees
Step-by-step explanation:
We can set up a proportion which would be
4/x = 8/100
This shows 4 out of x people is the same as 8% of 100.
We divide 100 by 8, and then multiply by 4 to get 50.
We can check this by plugging 50 into the proportion.
4/50 = 0.08
8/100= 0.08
There are 50 total employees at the shop.
