The formula that you will use will be the formula for the area of a circle, which is as follows:
A= Pi r^2
(Pi times the radius squared)
I think that would be a right angle triangle or is that not what it is meaning
Answer:
D
Step-by-step explanation:
5 ÷ 8 = 0.625 = 62.5%
Answer:
The total length is 1123 feet.
a) if the model is 30 inches long, the first thing we need to do is write inches in feets, so 1 feet is equivalent to 12 inches.
so 30 inches are 30/12 = 2.5 feets.
the scale is the ratio between the feets in the the two lengths.
1123/2.5 = 449.2
so the scale is 1:449.2
so each feet in the model is equivalent to 449.2 feets in the enterprise.
b) if the model is 2 feet long, then:
1123/2 = 561.5
the scale is 1:561.5
so each feet in the model is equivalent to 561.5 feets in the enterprise.
Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
