Answer:
1. 15.9
2. 12
3. 7.29
4. 20.8
5. 11.0
Step-by-step explanation:
We can use the Pythagorean Theorem to solve for x (a squared minus b squared equals c squared)
Example number 1 is solved by 17 squared - 6 squared equals 253
You do square root and get 15.90
Number 4 is you have to divide 24 by 2 because it is one of the sides
So it is 24 squared minus 12 squared
You find square root and get 20.80
Answer:
f(-1)=8
Step-by-step explanation:
Just plug in x=-1 into the function:
f(x)=6-2x
y=6-2(-1)
y=6+2
y=8
So f(-1)=8
So there's 8 tiles.
Radius from archway to the outer edge would be : 7 +1 = 8ft
You can use this formula to count the area of semi circle : π r^2/2
A = 3.14 x 8ft^2 = 100.48 ft ^2
A = 3.14 x 7ft^2= 76.92 ft^2
100.48 - 76.92 = 23.55 ft^2
Then you have to divide it with the total tiles
23.55/8 = 2.94 ft^2 per tile >> (rounded to nearest tenth)
