Answer:
220.5
Step-by-step explanation:
First, we can figure out the half circle. The area for that is pi times r squared divided by 2. So the area is 8 squared times pi divided by 2. So 64 divided by 2 is 32. 32 times pi is 100.530964915. We can round that to 100.5 and now the rectangle is 8 times 15. Which is 120. So 120 plus 100.5 is 220.5! I hope this helps! Please mark me Brainliest!!!
Answer:
24 days
Step-by-step explanation:
The least common multiple (LCM) of 8 and 12 is 8·3 = 12·2 = 24.
The ladies will be at the nail salon on the same day again in 24 days.
_____
8 = 2³
12 = 2²·3
The LCM will have these factors to their highest powers: 2³·3 = 24.
__
The LCM is also the product divided by their greatest common factor (GCF). GCF(8, 12) = 4, so ...
LCM(8, 12) = 8·12/4 = 24
Use the ratio of map distance to real distance.
3 cm : 15 km
Divide both sides by 3.
1 cm : 3 km
Convert both cm and km to meters.
0.01 m : 3000 m
Divide both sides by m, and multiply both sides by 100.
1: 300,000
Since the ground floor has 52 windows, and every floor, here are 6 fewer windows than the floor below it, we make a expression.
52-y=x.
We are trying to solve for x, not y.
In order to get 'y,' you have to multiply 8 by 6. Which is going to be 48.
(If you don't know multiplication, respectively.)
So now that we solved for y, =48 .... 52-48= ....... = x
Now all we have to do is simply subtract.
x=4.
So the answer to the problem is 4 windows on the 8th floor.
