Since 9 goes into 18 and 45, and both of the integers has a y2, the GCF is 9y2
To find the speed with given distance and time you just have to divide the distance by time. In this situation it's 396 miles in 6 hours, so it's 396 / 6 = 66 miles in 1 hour. So the speed is 66 mph.
Answer:
24 feet
Step-by-step explanation:
Use the perimeter formula, P = 2l + 2w, where l is the length and w is the width.
Plug in the values, and solve:
P = 2l + 2w
P = 2(7) + 2(5)
P = 14 + 10
P = 24
So, the perimeter of the canvas is 24 feet
Answer:
Pythagoras theorem.
hypotenuse²=height²+base²
x²=15²+12²
x²=225+144
x²=329
x=329½
x=19.20

what is 7.69/43.685=?
Answer:
The Correct Answer is 5.6 :)
Step-by-step explanation:
Change the divisor 7.69 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
4368.5 ÷ 769 = 5.6
and therefore:
43.685 ÷ 7.69 = 5.6
Both calculated to 1 decimal places.
