So 1/2 is 5/10 and 2/5 is 4/10 common denonominator is 10 ( i think )
Hey there! :D
We will use the properties of similar triangles to figure this out.
We will use two triangles inside the kite, with sides with the value of "x".
Smaller triangle:
Smaller side= 11
Bottom side= x
Bigger triangle:
Smaller side= x
Bottom side= 25

Cross multiply.
25*11= 275
x*x=

Find the square root.
√275= 16.583....
Or 5√11.
I hope this helps!

An art gallery is a 6-story square pyramid with base area of half an acre. Estimate the volume in cubic yards of the art gallery. In your calculations, use 1 acre = 4840 yd2 and 1 story = 10 ft.
<span>There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.

×<_ 24 is the answer I believe.
