It is a right triangle so,
a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x
Hope this helps :)
If only 6 friends attended Armando's cookout, and he kept 3 cards for himself, then, 42 divided by 6 is 7.
Therefore, each friend received 7 cards.
Setup: cos48 = x/25
25(cos48) = x
x = <span>16.728265159</span>
To solve this division would be the best way to go. First, set the 2 and 1/2 cups as 5/2. Then go to the lowest common denominator of 4 making 5/2 into 10/4. 3/4 can go into 10/4 3 times meaning that Roger can make 3 loaves of bread.
Answer:
D because mean is the subtraction of the biggest number and the smallest. so 17-8=9
