loris [4]

Given :

The value of the surface area of the cylinder is equal to the value of the volume of the cylinder.

To Find :

The relation between height and radius.

Solution :

$S.A=2\pi rh+2\pi r^2=2\pi r(h+r)$

$V=\pi r^2h$

Now ,

$S.A=V\\\\2\pi r(h+r)=\pi r^2h\\\\2(h+r)=rh\\\\2h+2r=rh\\\\h(2-r)=-2r\\\\h=\dfrac{2r}{r-2}$

Hence, this is the required solution.

I. Daska is situated at a distance of 15 miles from both Gujranwala and Sialkot. A bus travels from Gujranwala to Daska at an av

son4ous [18]

Answer:

The average speed of the entire trip is 8.5 miles per hour.

Step-by-step explanation:

Speed = Total Distance / Total Time

So we have to find the total distance and the total time taken .

1) From Gujranwala to Daska

speed= 25miles/hour distance = 15miles

Time taken = distance / speed

= 15/25= 0.6 hours

2) From Daska to Sialkot

speed= 40miles/hour distance = 15miles

Time taken = distance / speed

= 40/15= 2.67 hours

3 ) From Sialkot to Daska

speed= 30miles/hour distance = 15miles

Time taken = distance / speed

= 30/15= 2 hours

The total distance traveled to three places is = 15+ 15+15= 45miles

The Total time taken is = 0.6+ 2.67+ 2= 5.267=5.3 hours

Speed = Total Distance / Total Time

Speed= 45/ 5.3

= 8.49=8.5 miles per hour

The average speed of the entire trip is 8.5 miles per hour.

2x-3y=15 solve and show steps please!!

Rufina [12.5K]

Solving for Y:

1) Subtract -2x from both sides: -3y=15-2x

2) Divide by -3 on both sides: y=-5+(2/3)x

Final Answer: y = (2/3)x-5

1. John began his job making $25 the first day. After that he was paid $6.75 per hour. a) Use the equation y 6.75x +25 to comple

iren [92.7K]

Answer:

a. Chart (attached)

b. and c. graph attached

Step-by-step explanation:

a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.

So, when x=0, $y=6.75\times 0+25=25$

when x=20, $y=6.75\times 20+25=160$

when x=40, $y=6.75\times 40+25=295$

b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)

c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
