There are 95 seats on a train. 19 of the seats are empty. What percentage of the seats on the train are empty?

1 answer:

7 0

Your answer is 20%

To find any percentage, you write it as a fraction and then multiply by 100. In this case, we have 19/95.
19 x 5 = 95, which means that 19/95 = 1/5

1/5 as a decimal is 0.2, and 0.2 x 100 = 20%

If you’re allowed to use a calculator for this question, then you can just type in (19/95) x 100 into your calculator to get the answer.

I hope this helps!

Answer:

The answer would be y = -1/2 x + 3

Step-by-step explanation:

So to solve this problem we have to look at the graph.

We have to put it into y = mx + b.

The B would be where the line crosses the y - intercept.

The mx would be how fast is the line going up/down.

If it is going down, it would be negative.

If it is going up, it would be positive.

I hope I helped.

Answer:

$\frac{9}{2}\pi +35$

Step-by-step explanation:

The area of trapezoid is given by the formula:

$A=\frac{1}{2}(b_1+b_2)h$

Where

A is the area

b_1 is base 1

b_2 is base 2, and

h is the height

Looking at the figure, base 1 is the left line which goes from y = 3 to y = 3, so 6 units. Also, base 2 is the right line which goes from y = -3 to y =5, so 8 units.

The height is the horizontal distance in the middle, which goes from x = -2 to x = 3, so 5 units. Hence area of trapezoid is:

$A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(6+8)*5\\A=35$

Now, area of semicircle is:

$A=\frac{\pi r^2}{2}$

Where

A is the area

r is the radius

Looking at the figure, the diameter (twice radius) goes from y = -3 to y = 3, so 6 units. But radius is half of that, so 3 units. Hence area of semicircle is:

$A=\frac{\pi r^2}{2}\\A=\frac{\pi (3)^2}{2}\\A=\frac{9}{2} \pi$
