Answer:
65.312 inches
326.56 inches
1959.36 inches
Step-by-step explanation:
Given
d = 20.8 inches
To find
Travel in 1, 5, 30 rotations
Solution
Circumference of the wheel is equal to one full rotation
C = πd = 3.14*20.8 = 65.312 inches
5C = 5*65.312 = 326.56 inches
30C = 30*65.312 = 1959.36 inches
Step-by-step explanation:
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67

Which of the sets of ordered pairs represents a function? (4 points) A = {(−4, 5), (1, −1), (2, −2), (2, 3)} B = {(2, 2), (3, −2

A function will not have any repeating x values....it can have repeating y values, just not the x ones
(-4,5),(-1,1),(2,-2),(2,3)
this is not a function because it has 2 sets of points that has x as 2...so it has repeating x values
(2,2),(3,-2),(9,3),(9,-3)
this is not a function because it has 2 sets of points that has an x value of 9...so it also has repeating x values
so both of these are not functions.....neither of them
Answer:
360 people in 3 hours. 120 people per hour.
Step-by-step explanation:
How many times do 20 minutes go into 3 hours?
Well, 60 min. ÷ 20 min. = 3
So, 3 x 3 = 9
So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.
So 3 hours would be 9 x 40 = 360
120 people per hour because 40 x 3 = 120
and 20 minutes (3) times equals 1 hour.
