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 :)

Answer:
the answer is 2.
Step-by-step explanation:
This is because the interest rate is if he had $1 in the account for a year you would add the 18% or in decimel form 0.0018 do that to the 15th to get 15 years and multiply that by 5000 because that was the ammount of money he put in so 5000(1*0.0018)15 or 0.0018^15*5000
Answer:
- 1/4 of a pound
- 4/15 of the flat
Step-by-step explanation:
For number 1:
- 3/4 ÷ 3 = 0.25
- 0.25 = 1/4
For number 2:
- 4/5 ÷ 3 = 4/15
I hope this helps!
Answer:
10 km
Step-by-step explanation:
volume of cube = s^3
1 m = 100 cm
volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3
Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.
1,000,000 cm = 10,000 m = 10 km
Answer:
