Answer:
A) 60 Degrees
B) 550 Feet
C) 2.5 minutes
Step-by-step explanation:
a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution
1 min = 60 secs
10 min = 600 secs
100/600 = 1/6
One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .
360/6 = 60°
b) It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference
= 550 Feet.
C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .
.
After solving this equation as there is only one unknown which is "<em>t</em> "the answer will be 2.5 minutes.
Answer:
I think the answer is D!
Step-by-step explanation:
(1) -1.79, 2 1/4, 2.54 , -4
negative -> positive
reorder: -4. -1.79, 2 1/4 (or 2.25), 2.54
(2) -x
The larger x is the smaller the value
-$40.75<-$25.20
BUT the larger after the minus the more you owe so Renae owes more.
(3)
sorry idk
(4)
78F-x=70F
|x|=8*F
The answer is -140
Because if subtract all of these you will get -140
