Answer:
2.5 miles per hour
Step-by-step explanation:
ok, so we already know how long she walked in 1/2 hour and we need to find out how many miles in one full hour. So, i multiplied 1 1/4 times two to make up the one full hour and I got 2.5 miles. So the rate is 2.5 mph.
Answer:
1/25 of a mile per minute, I think
Step-by-step explanation:
The amount of material/ number of pillows made
16/12 = 4/3 = 1 1/3
So the answer lies between integers 1 & 2
DF=14. Because DE is half the line and EF is the other half the line you add up both the lengths to get the length of whole line.
DE=EF. DE and EF both equal 7 so they are equal.
Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders
