Answer:

Johnny and his family left home at 10:00.

Step-by-step explanation:

First, You add all of the minutes up,

45+20+10= 75

Then convert the minutes to hours,

75 mins = 1 hr and 15 mins.

Add the hours together,

1 hr + 2 hrs = 3 hrs

Then add minutes,

3 hrs and 15 minutes

Subtract 3 hrs and 15 mins from 13:15,

13.15 - 3.15 = 10:00

Your answer is:

Johnny and his family left home at 10:00.

Answer:

Volume of Pipe is 226 ft³.

Step-by-step explanation:

Given:

Cylindrical Shape Pipe having

Height = 18 ft

Diameter = 4 ft

∴ $Radius =\frac{Diameter}{2}=\frac{4}{2}=2\ ft$

To Find:

Volume of Pipe = ?

Solution:

Formula for Volume of Cylinder is given by

$\textrm{Volume of Cylinder}=\pi (Radius)^{2} \times Height$

Substituting the given values we get

$\textrm{Volume of Pipe}=3.14\times 2^{2} \times 18\\\\\textrm{Volume of Pipe}=226.08\\\\\therefore \textrm{Volume of Pipe}=226\ ft^{3}$

Volume of Pipe is 226 ft³.

Find (g o f)(-1). *

klio [65]

Answer:

D -9

Step-by-step explanation:

(g o f)(-1) = g(f(-1))

f(-1) = $f(-1) = (-1)^{2} + 2(-1) - 3\\= 1 - 2 - 3\\= -4$

g(-4) = -4 - 5 = -9

So, (g o f)(-1) = -9
