Answer:
128 feet
Step-by-step explanation:

So now we will substitute the values of T and π into the equation.


Divide both sides by 6.28

Square both sides.

Multiply both sides by 32

Answer:
<u>20/48 = 42%</u>
Step-by-step explanation:
<u>Number of beige tiles</u>
- 48 - 8 - 6 - 9 - 5
- 40 - 6 - 9 - 5
- 34 - 9 - 5
- 25 - 5
- 20 beige tiles
<u>Probability (Beige)</u>
- No. of beige tiles / Total no. of tiles
- <u>20/48 = 42%</u>
Answer:
340
Step-by-step explanation:
We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.
0.36*942= 339.12 which we can round to 340
Answer:
Ok so the area of the frame is 18*12 = 216cm^2
Let’s suppose the width of the frame is x
The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432
4x^2 + 60x + 216 = 432
4x^2 + 60x - 216 = 0
x^2 + 15x - 54 = 0
(x+18)(x-3) = 0
Therefore x = {-18,3}
Since width of the frame has to be positive, the width has to be 3cm Step-
