Traingle GIH and FGH are similar triangles because they both have angle H and a right angle. Since the angles in a triangle must add to 180 you know that angle their third angle is also the same. You can caculate GH through Pythagorean theorem to get around 21.9. Now you that you can use similar triangle ratios such as GF/GH is equal to IG/IH. Now plug in the numbers to get GF/21.9=15/16. GF is 20.5. Then using Pythagorean theorem FI is sqrt(20.5^2-15^2) or 13.9.

The altitude is the mean proportional between the left and right parts of the hyptenuse

\cfrac{FI}{GI} =  \cfrac{GI}{HI} \ \ \Rightarrow \ \  \cfrac{FI}{15} =  \cfrac{15}{16} \ \ \Rightarrow \ \ FI= \cfrac{15 \cdot 15 }{16} \approx  14.1

Answer: 14.1

A farmer has 64 feet of fence to enclose a rectangular vegetable garden. which dimensions would result in the biggest area for t
Blababa [14]
The dimensions that would result to maximum area will be found as follows:
let the length be x, the width will be 32-x
thus the area will be given by:
P(x)=x(32-x)=32x-x²
At maximum area:
dP'(x)=0
from the expression:
P'(x)=32-2x=0
solving for x
32=2x
x=16 inches
thus the dimensions that will result in maximum are is length=16 inches and width=16 inches

The graph shows a reflection.
Andru [333]

Answer:

false

Step-by-step explanation:

the only difference is the fact that it was reflected over the y-axis. the size of the triangle was not altered. the triangles are the same size, just different locations.

Step-by-step explanation:

The formula for finding the area of a trapezoid is\frac{b_{1} + b_{2} }{2} ×h

Start by substituting the values given in the problem into the formula

\frac{5+7}{2} ×4

Now Simply/solve

\frac{12}{2} ×4

6×4

A team is selling pop corn for a fundraiser. The first week, they sell 500 bags. The second week, they sell 50% more than the fi
Dmitriy789 [7]

Answer:

The percentage decrease from the first week to the third week is 25 %

Step-by-step explanation:

The number of popcorn bags sold on the first week = 500 bags

The second week, they sell 50% more than the first week

So, the number of bags sold on the second week is

= 500 + 50% of 500

=500 +  \frac{50}{100}  \times 500

= 500 + 0.5 \times 500

= 500 + 250

= 750 bags

The third week, they sold 50% less than the second week

So, the number of bags sold on the third week is

=  750 - 50% of 750

= 750 - \frac{50}{100} \times 750

= 750 -0.5 \times 750

= 750 - 375

= 375 bags

Now the percentage decrease from the first week to the third week is

=\frac{500 - 375}{500} \times 100

= \frac{125}{500} \times 100

= 0.25  \times 100

= 25 %
