Answer:
48
Step-by-step explanation:
80 divided by 4 is 20 so thats 1/4 of 80
80-20=60
1/5 of 60 = 12
20+12=32
80-32=48

25 - <u>(2n + 8)</u> < the sum of 2 times N plus 8.
Step-by-step explanation:
To answer this you have to use Pythagoras's theorem: a^2 + b^2 = c^2
Put in the values:
5^2 + 15^2 = c^2
Simplify it:
25 + 225 = c^2
Simplify again:
250 = c^2
Square root both sides:
15.8113883008 = c
So the ramp is:
15.8113883008 feet
Now round the number:
15.8ft
The above is the answer :)
