Answer:
28 ft
Step-by-step explanation:
The height of the triangle = 15 ft
The least required area A = 210 ft^2
We know that the area of a triangle = 1/2bh
Where
b is the base
h is the height
Substituting, we have
210 = 1/2 x b x 15
210 = 15/2 x b
420/15 = b
b = 28 ft
When you are going from a larger measurement (such as meter) to a smaller measurement (such as centimeter), you will have to multiply by units of ten. Specifically if you are going from m to cm, you will use (n x 10^2) with n being the given number for meters. When you are going from a smaller measurement (such as centimeter) to a larger measurement (such as meter), you will have to divide by units of ten. Specifically if you are going from cm to m, you will use (n / 10^2) with n being the given number for centimeters.
Yes it is because it has no square factors.
Answer:13
Step-by-step explanation:
3,5,7,9,11,13
The square root of (64/225) is the same as √64 / √225 .
That could make the whole thing easier.
Do you know what either of those separate square roots is ?
You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 .
You really know your stuff !
So now, the expression is √64 / √225 = <em>8 / 15</em> .
Oh, I almost forgot, it has a negative sign before it. OK,so the answer is <em>- 8/15</em> .
