Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can
artcher [175]

Answer:

The house is 18.75 feet tall

Step-by-step explanation:

The triangles are similar by the AA postulate.  

We are given the length of the bottom sides of the triangles, 4 and 15 respectively.  

Thus, the ratio is 4:15

We are also given the height of Annie's eyes, which is 5 feet. The height of the side that corresponds to the house is 5, so we can set up a proportion.

\frac{4}{15}  = \frac{5}{x} \\4x = (5*15) = 75\\x = \frac{74}{4} \\x = 18.75

Thus, the house is 18.75 feet tall.

A and b are positive integers. Find −2a+3b if a^3 b^2=72.
Alexxx [7]
The answer for "-2a + 3b" is 5.

To solve this equation, you must first find "a" and "b". A^3 times B^2 = 72. In this case, a = 2 (2*2*2 = 8) and b = 3 (3*3 = 9) since their outcomes multiplied together equal 72.

Now you fill in for "a" and "b". "-2*2 + 3*3" before adding you do all the multiplying, which leaves "-4 + 9". Combining like terms gives you 5.

I hope this helps!!

URGENT TEST I HAVE!!!!
Lerok [7]

Answer:

I think they are asking the area of the triangle so we are going with that.

Step-by-step explanation:

Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.

so it is 4 cm wide

and 8 cm tall

length x width = area

8 x 4 = 32

32/2 = 16

So your answer should be 16 cm
