Answer:

24 shots

Step-by-step explanation:

$\frac{15}{y}= \frac{63}{100}$

y × 63 = 15 × 100

63y = 1500

63y ÷ 63 = 1500 ÷ 63

$y=23\frac{17}{21}$

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

Can someone please help me with this.

LenKa [72]

Answer: The answer it C. 135

Step-by-step explanation:

It is a supplementary angle so therefore it’s supposed to equal 180 degrees.

So, 180-45= 135

The graph below shows the rate that water leaves a tank, in gallons per hour, where t is measured in hours. (Please give exact a

defon

Answer:

Part a) 10 gallons

Part b) 4.59 hours

Step-by-step explanation:

The picture of the question in the attached figure

Part a) How much water left the tank during the 6 hours shown?

To find out how much water left the tank during the 6 hours, determine the area of the graph in that interval

Calculate the area of the rectangle plus the area of the triangle

$(4)(2)+\frac{1}{2}(6-4)(2)$

$8+2=10\ gal$

Part b) How many hours did it take for 9 gallons to leave the tank?

we know that

In the interval [0,4]

8 gallons of water leaves the tank in 4 hours (remember that the area in that interval is equal to 8 gallons)

Find out in the interval (4,6] how many hours did it take for 1 gallon to leave the tank

First determine the equation of the line in the interval (4,6)

we have the points (4,2) and (6,0)

The slope is equal to

$m=(6-2)/(0-4)=-1$

The equation of the line is

$y=-(x-6)\\y=-x+6$

Determine the area of graph in the interval (4,x) (Is the area of trapezoid)

$A=\frac{1}{2}(2+(-x+6))((x-4)$

$A=\frac{1}{2}(8-x)((x-4)$

$A=\frac{1}{2}(-x^2+12x-32)\\\\A=-\frac{1}{2}x^{2}+6x-16$

For A=1 gal

$1=-\frac{1}{2}x^{2}+6x-16$

$-\frac{1}{2}x^{2}+6x-17=0$

solve the quadratic equation by graphing

The solution is x=4.59 hours

see the attached figure N 2
