1.29x=21+.99x
You want them to become equal, and you can get that if you get x by itself.
.3x=21
21/.3= 70= x
So at 70 downloads, they'll be the same. We can check to see if we're right.
1.29 ×70=90.3
21 + 69.3 = 90.3
So they'll be the same at 70 downloads, and they'll cost $90.30.
Answer:
It will take Naomi 22 hours
Step-by-step explanation:
If they work together Mark, Naomi, and Yvonne take 11 hours, which means
three people represent 3* 11 = 33 man* hours
If they work alone Yvonne will take 5 man hours, and Mark will take 6* man hours.
Now we know that together they take 33 man hours therefore we have
5+ 6+ N = 33
Where N is Naomi's man* hours. We solve for N and get:
N = 33 - 11 = 22
N = 22
Naomi will take 22 hours to finish the job if she worked alone.

Answer:
Howdy! Let me see if I can be of assistance.
This is a triangular prism that we must solve for, and there are a few steps that can guarantee you land on the right answer.
1) Plug the base and height numbers into the formula, where V is volume:
V= 1/2 × base × height
which becomes
V= 1/2 × 6 × 10
Note that either of the base numbers will work, since the ratio is the same.
2) multiply both of those numbers by 1/2 and you will have your answer! I leave that to your capable hands.
P.S. remember to put the answer down as centimeters squared
Happy learning, friend!
