Answer:

82 (B)

Step-by-step explanation:

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). To find the median, all you have to do is list down, in a row, all the numbers. Then scratch off the first and last number and keep doing that. not sure how to explain it, but like this.  64,67,70,70,70,73,76,79,79,82,82,85,88,91,94,94,97,97,100,100,100

the number left in the middle, as you can see, is 82.

Calculate the surface area and volume of the shape below.
pav-90 [236]

Surface area

Let's calculate the surface area of the rectangular block. It has length, width and height of L = 15, W = 5, H = 8. The surface area is going to be

SA = 2*(LW+WH+LH)

SA = 2*(15*5+5*8+15*8)

SA = 470

This is without the cylinder attached to the top surface. If we account for that, then we'll have to subtract off the area of the circle covered up which is

pi*r^2 = pi*3^2 = 9pi = 28.27433 approximately

So 470-28.27433 = 441.72567 is the approximate surface area of the rectangular block after we subtract off the circular portion covered up by the cylinder.

----------

The lateral surface area of the cylinder is approximately

2*pi*r*h = 2*pi*3*4 = 24pi = 75.39822

Which adds onto the top circular area of 28.27433 to get 28.27433+75.39822 = 103.67255

Meaning that 103.67255 is the surface area for the cylinder portion. Again we don't worry about the bottom portion as it's not part of the outer surface.

---------

Overall, the total surface area of this compound 3D figure is

(surface area for rectangular portion) + (surface area cylinder portion) = 441.72567+103.67255 = 545.39822

When rounding to the nearest whole number, the total surface area is about 545 square cm

<h3>Answer: 545 square cm</h3>

============================================================

Volume

The rectangular block has volume L*W*H = 15*5*8 = 600 cubic cm

The cylinder has volume pi*r^2*h = pi*3^2*4 = 113.0973355 approximately

Add the two volumes to get 600+113.0973355 = 713.0973355 and this rounds to 713. We don't have to do any subtraction in this section.

<h3>Answer: 713 cubic cm</h3>

A bus​ averages 8 miles per hour faster than a trolley. If the bus travels 60 miles in the same time it takes the trolley​ to tr
hammer [34]

Answer:

Bus speed:  22 mph; Trolley speed:  14 mph

Step-by-step explanation:

Let rb represent the speed of the bus and rt the speed of the trolley.  Then rb = rt + 8 (mph).

Recall that distance = rate times time.  Two different distances and two different speeds are involved here, but only one time.

Thus,

             60 mi                                                           44 mi

     --------------------- = time (same in both cases) = -------------

          rt + 8 mi/hr                                                        rt

Cross-multiplying, we get   44rt + 8(44) = 60 rt, or

                                                    352 = 16rt.

Solving this for rt, we get    rt = speed of bus = 352/16 = 22 mph

The speed at which the bus travels is 22 mph and that at which the trolley travels is (22 mph - 8 mph) = 14 mph
