Answer:

Step-by-step explanation: so first u wanna put them in order -40, 11, 12, 12, 15, 29, 59, 86

The median is pretty much the number in the middle so it’s 15. Mode is the number that repeats the most so it’s 12. And mean is adding all the numbers together and then dividing it by how many numbers are there. So it is 23

How to solve this equation 7-2a-5-14=-2+3a

SSSSS [86.1K]

To solve 7-2a-5-14=-2+3a :

1) combine like terms: 7-19 - 2a = -2 + 3a, and then -10 = 5a

2) solve this equation for a: a = -10/5 = -2.

The solution of 7-2a-5-14=-2+3a is a = -2.

a ferris wheel rotates 9pi/8 radians prior to making a stop the total height of the ferris wheel is 246 ft how far around did th

Zinaida [17]

Answer:

ferris wheel travel approx = 434.72 ft

Step-by-step explanation:

given data

wheel rotates = 9pi/8 radians

total height of the ferris wheel = 246 ft

solution

we can say here that height of the ferris wheel is same as the diameter of the wheel

and wheel is circular in shape

so we get here first radius of wheel that is

radius = half of diameter ..........................1

put here value and we get

radius = 0.5 × 246

radius = 123 ft

and

wheel travel distance = length of arc by a angle of wheel rotates

so here length of arc will be

arc length = radius × wheel rotates angle .....................2

put here value and we get

arc length = 123 × $\frac{9\pi }{8}$

arc length = 434.7178 ft

so ferris wheel travel approx = 434.72 ft
