Answer:

21 kilometers

Step-by-step explanation:

Let the height be x. Then, the length of the base is 2x. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to \frac{x \cdot 2x}{2} = x^2, which is in turn equal to 441. Since x must be positive, then 21^2=441, meaning that the height is 21 kilometers.

Then add 8 to the amount that does not play either instrument:

8 + 7 = 15

Then do:

26 - 15 = 11

Then place 11 over the amount of people:

11/26

Answer:

30 to 50 more feet

Step-by-step explanation:

Add up all the sides to find the perimeter of the shape for the pen:

18 + 22.5 + 5 + 4.5 = 50

Since 50 is less than 80 to 100, then Annie has 30 to 50 more feet she can use for the pen.

TEA [102]
Its C, It can't be equal because it is not dividing by 1, It can't be less than 0.4 because if you divide by a decimal the quotient will increase. So the obvious choice is C because it will be greater than 0.4. Also a question for you, why use this website to get answers when there are online calculators....
