Answer:
Step-by-step explanation:
If ali has 23 so Raina has 7 more than Ali = 23 + 7 = 30
And trey has 4 times as much as Ali = 23 x 4 = 92
Total = 92 + 23 + 30 = 145
We see that the area is 159 3/8 and the length is 18 3/4.
Because the area is the length*width, to find the width, we must divide the area by the length.
Think of it this way:
Divide l on both sides:
And w is what we're looking for.
So, divide 159 3/8 by 18 3/4.
You should get that the width is 8.5 feet :)
Answer:
2.3456 x 10^-5
Step-by-step explanation:
Cos = adjacent over hypotenuse
cos33 = b/170
170cos33 = b
b = 142.574 inches
For this case we have:
way 1:
Common factor 3 in the expression:
Way 2:
Write the number 12 as the sum of 4 times 3:
Then, for associative property:
