71° is the answer. 44°+27°=71°
Answer:
h = 18( I might be wrong though)
Step-by-step explanation:
If BE and ED are perpendicular, that means this angle is supplementary.
BEF = 3h-12
FED = 2h - 23
BEF + FED = 90
3h-12 + 2h - 23 = 90
5h - 35 = 90
5h = 90
h = 18 degrees
The more painstaking way would be to divide the spinner up into 100 pieces, and shade in 5 of those pieces. Since 5/100 = 0.05 = 5% this means that landing on any of the 5 pieces has a 5% chance of happening.
A better way to do this is to use 20 slices instead. This works because 5/100 reduces to 1/20 (divide top and bottom by 5). Instead of shading in 5 slices, Mark should shade in 1. If you use a calculator, you should see that 1/20 = 0.05 = 5% as well.
The second option is more practical but even then a spinner with 20 sections is still a lot. I think it might be better for Mark to pull random numbers out of a hat, or let the computer generate random numbers.
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
1,000 is equal to 10^3
So it will take the comet 10^3 days to reach earth.
