True [87]

Answer:

B

Step-by-step explanation:

The question is:

<em>What percent of time did Nik spend with clients on Thursday? </em>

<em>a. 10% </em>

<em>b. 70% </em>

<em>c. 30 % </em>

<em>d. 80%</em>

<u>Solution:</u>

c means client meetings and o means other work.

The hours are shown in the table.

We want % of time on Thursday that he spent on clients.

In Thursday:

7c and 3o

Means 7 hours with clients and 3 hours with office work.

Total time spent = 7 + 3 =  10 hours

Client time spent = 7 hours

% time spent with clients on Thursday: 7/10 = 0.7 * 100 = <u>70%</u>

<u>Answer choice B is right.</u>

A boat traveled 240 miles downstream and back. The trip downstream took 12 hours. The trip back took 24 hours. What is the speed
RoseWind [281]

Answer:

rate boat = 15 mph

rate current = 5 mph

explanation:

d = r * t

t = d/r

240 / (r_boat + current) = 12       Multiply both sides by r_boat + r_current.

240 = 12(r_boat + current)

240/ (r_boat - current) = 24       Multiply both sides by r_boat - r_current

240 = 24*(r_boat - current)    

Since the distances are the same in both equations, you can equate the right side of each.

12 (r_boat + current) = 24(r_boat - current)     Divide by 12

r_boat + current  = 2 (r_boat - current)             Remove the brackets.

r_boat  + current = 2*r_boat - 2* current          add 2 currents to both sides

r_boat  + 3currents = 2*r_boat                          Subtract r_boat both sides

3 currents = r_boat.

240 = 12*(r_boat + current.                               Divide by 12

20 = r_boat + current                                        Put 3 currents in for r_boat

20 = 3currents + 1 current                                Combine

20 = 4 currents                                                  Divide by 4

5 = current

The rate of the current = 5 miles / hour

3 currents = r_boat

3*5 = rate_boat

15 = rate of the boat
