A Ferris wheel has a diameter of 56 ft. how far will a rider travel during a 4-minute ride if the wheel rotates once every 20 se

Luba_88 [7]

First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 = 2112 feet

-q/7>-1<br><br> Help plz Step-by-step

alisha [4.7K]

Answer:

q < 7

Step-by-step explanation:

Given:

$\frac{-q}{7} > -1$

Required:

Find the value of q.

First, multiply both sides by 7

$7 * \frac{-q}{7} > -1 * 7$

-q > -7

Then, multiply both sides by -1

q < 7

Note that the sign of the inequality changed.

When multiplying or dividing an inequality by a number less than 0 (in other words, a negative numbers), the sign of the inequality will change.

Hence, the solution to the expression above is

q < 7
