a. How many degrees would the Ferris wheel rotate in 100 seconds?
b. How far has a person traveled of he or she has been on the Ferris wheel for 7 minutes?
c. How long would it take for a person to travel 200 feet?
Try to show work :))
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 "t "the answer will be 2.5 minutes.
g(2)=5
g(n)=g(n-2)+g(n-1)
g(3)=
Answer:
g(3) = 5
Step-by-step explanation:
g(3) = g(3-2) + g(3-1) = g(1) + g(2) = 0 + 5 = 5
Answer:
g(3)=5

Write an expression that represents the perimeter, in centimeters, of the triangle.
Show all work.
PART B:
Write an equivalent expression to represent the perimeter from PART A. by factoring out the greatest common factor.
Show all work.
IF ANSWER BOTH I WILL GIVE BRAINIEST
Answer:
Step-by-step explanation:
Part A : Since sides of triangle are ( 1.9x + 6.2y )cm
(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.
Now perimeter of a triangle = sum of all sides length
Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)
= (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)
[ collecting the like terms together ]
Perimeter = 4.4x + 1.1y + 9.9w
Part B : Now we factorize the term for perimeter given in part A.
Perimeter = 1.1 (4x + y + 9w)
So equivalent factor will be (1.1 (4x + y + 9w).
Answer:
see explanation
Step-by-step explanation:
A
The perimeter is the sum of the 3 sides, thus summing the 3 sides
1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms
= 4.4x + 1.1y + 9.9w ← expression for perimeter
B
Factor out 1.1 from each term, thus
4.4x + 1.1y + 9.9w
= 1.1(4x + y + 9w) ← perimeter in factored form
