Jim started cleaning at :1009 AM and finished at :1132 AM.<br> How long did it take him?
Goryan [66]

Answer:

1 hour and 23 minutes

Step-by-step explanation:

11:32-10:09=1:23

Thinking through this logically, one hour after 10:09 is 11:09 and we know that it took him longer than this.

We can then subtract the minutes without having to worry about the base-60.  

32 minutes -9 minutes =23 minutes

We then add the 23 minutes to the 1 hour and determine that it took him 1:23 (one hour and twenty-three minutes).

Anastaziya [24]

Answer:

The answer to your question is 4 ft

Step-by-step explanation:

Data

Building's shadow = 288 ft

Building's high = 64 ft

Sarah's shadow = 18 ft

Sarah's height = ?

Process

1.- Use proportions to solve this problem

                               \frac{Sarah's height}{Sarah's shadow} = \frac{building's height's}{building's shadow}

2.- Solve for Sarah's height

  Sarah's height = \frac{Sarah's shadow x building's height}{building shadow}

3.- Substitution

  Sarah's height = \frac{18 x 64}{288}

4.- Simplification

  Sarah's height = \frac{1152}{288}

5.- Result
