Im not rlly sure about this it seems confusing
Ok so you have to do the area of three different shapes then add them together so to find the area for the square and rectangle you need to find the sides to be equal so the square is already set you would do 6 times 5 and get 30 so how to do the rectangle is add 7 and 5 and get 12 so you would do 10 - 6 and get 4 and then do 12 times 4 which is 48 so, so far you have 78 for an area but you a triangle so you have a base of 3 because we found that the rectangle is 12 so 15-12 is 3 then we did the side for the rectangle which was 10-6 is 4 so for the triangle you would do 1/2 times 3 times 4 which would be 6 so 78 plus 6 and you would get 84 so A is your answer
No. Two angles will have to be the same and the third angle will just be 180° minus twice the smaller angles.
So if we let the equal angles equal a, and the large angle equal be we have:
2a+b=180
So there are infinitely many values that a and b can have.
a=(180-b)/2, so the smaller equal angles have the range (0,90)
b=180-2a, so the larger has a range of (0,180)
1. 77 mph
We already know they travel 38.5 miles in 30 minutes. So we multiply 38.5 x 2 because 30 minutes is 1/2 of an hour. 38.5 x 2 = 77
5. 8.5 minutes (8 minutes and 30 seconds) per mile
We have to divide 25.5 by 3 to know how many minutes it takes Jerry to run one mile.
8. 34.06
This one is kinda easier. We already know 34 is the whole number. 6 divided by 100 is 0.06, so we simply add 34 + 0.06
