A] David's speed during the period:
i] AB
speed=distance/time
time taken between AB=0.5 hours
distance=20 km
thus
speed=20/0.5=40 km/h

ii]BC
time taken between BC=1.5 hours
distance=20
speed=20/1.5=13 1/3 km/h


b] Average speed for the entire time will be:
average speed=(total distance)/(total time)
total distance=(20+20+20)=60 km
total time=3 hours
thus
average speed=60/3=20 km/h


c] David's distance 2 hours and 15 minutes from the starting point was:
 distance=20+20+10=50 km

Find the angle marked with the ? mark
Yuri [45]

Answer:

53 degrees

Step-by-step explanation:

Angle N = angle E

because angle made by joining end points of same chord on circumference are always equal.

so angle E = 37

Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)

Now in Triangle DEC. Sum if all the angles of triangle us 180

Angle D + angle E + ? = 180

37 + 90 + ? = 180

127 + ? = 180

? = 180 - 127

? = 53 degrees

Which of the following is the point and slope of the equation y - 3 = (x - 5)?
Ilia_Sergeevich [38]

<u>ANSWER:  </u>

The slope of the given line y - 3 = (x - 5) is 1 and (5, 3) is a point on that line.

<u>SOLUTION: </u>

Given, line equation is y – 3 = (x – 5)

We have to find the slope of the given equation along with a point on that line.

Now, if we observe, the given equation is in point slope form y-y_{1}=m\left(x-x_{1}\right)

Where, m is the slope of the line and \left(x_{1}, y_{1}\right) is a point on the line.

Now by comparison of the two equations we can conclude that,

\mathrm{m}=1 , x_{1}=5 \text { and } y_{1}=3

So, the point on the given line is (5, 3).

Hence, the slope of the given line is 1 and (5, 3) is a point on that line.

I need help I would appreciate it if u would help me with this problem :)
schepotkina [342]

Answer:

The answer is letter A.

Step-by-step explanation:

 The amount that each company charges per hour on the pool is known, however the amount of hours they will be working is not, and is needed to distinguish which company is cheaper. Therefore, the number of hours is  substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).
