The answer is C-16
This is because if your set up a proportion
——=—— you put 6 over 15 like a fraction form and then = x over 40 x because you don’t know how many he can make in 40 mins and the 40 is right next to the 6 over 15 because we are trying to find how many paper boats we can make not the time therefore the answer is 16
D) 66.0 mi/h
because to find the average, you have to add up all the numbers and for each number you add, you divide it.
66+72=132
132÷2= 66.0
Answer:
30/11
Step-by-step explanation:
Let's say x = 2.7272727272... If we multiply both sides by 100, we get:
100x = 272.7272727272...
We now have the equations:
100x = 272.7272727272...
x = 2.7272727272...
Let's subtract the second from the first. Doing so results in 99x on the left. On the right, the entire repeating part (72727272...) cancels out and we're just left with 272 - 2 = 270:
99x = 270
Divide by 99 on both sides:
x = 270 / 99
Simplify:
x = 30 / 11
The answer is 30/11.
Answer:
square feet
Step-by-step explanation:
Units multiply the same way any variable does:
(x ft)(y ft) = x·y ft·ft = x·y ft² . . . . . . the units of the product are square feet
