Answer:

  9:20 am

Step-by-step explanation:

The cycles will coincide again at the least common multiple of the cycle times.

  20 min = 4 × 5 min

  16 min = 4 × 4 min

The least common multiple of these times is 4 × 4 × 5 min = 80 min. 80 minutes after 8 am is 9:20 am.

The two buses will next leave at once at 9:20 am.

Hannah made a ramp for her grandfather who was in a wheelchair. The ramp was 10 ft long and it was 5 ft away from the porch step
lianna [129]

Given :

Length of ramp( Hypotenuse ), l = 10 ft .

Length of base, b = 5 ft .

To Find :

How high were the porch steps.

Solution :

Let, height is h.

By Pythagoras theorem :

b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft

Hence, this is the required solution.
