Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
Answer:
Area: 312
Perimeter: 75
Step-by-step explanation:
Area is l·w
20·16=320
two corners aren't filled
320-9-9=318
Add all the sides for perimeter
17+3+3+13+20+13+3+3=75
Answer:
u = 4
v = 18
Step-by-step explanation:
in a parallelogram, diagonals bisect each other into two equal segments so we can do the following:
2u+2 = 5u-10
subtract '2u' from each side to get:
2 = 3u-10
add 10 to each side to get:
12 = 3u
12/3 = u
u = 4
To solve for 'v':
v/3 = 6
multiply each side by 3 to get:
v = 18
Answer:
33 years
Step-by-step explanation:
I think you might have made a typo, but it would still be 33 if the mean age stays the same.
Here we are supposed to turn 5 into fraction.
as we know the fraction is written in the form of p/q
So we can write

Hence fraction =
