Answer:
-3-7e/3e
Step-by-step explanation:
d - 4d=3/e +7
-3d= 3/e +7
-3d=(3+7e)/e
d=(-3-7e)/3e
Do you have pictures of the graph? but just pic the one that goes up 3 because its asking about number of math questions..
Answer:
The surface area of the prism is 72 square units.
Step-by-step explanation:
In order to calculate the surface area of the prism we must calculate the area of each face of the prism. To better visualize it we can look at the picture below. We must calculate the area of every face in the picture, so we have:
surface area = 2*[(1/2)*3*4] + 3*5 + 4*5 + 5*5
surface area = 12 + 15 + 20 + 25
surface area = 72 square units
First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
