Answer:
101 revolutions
Step-by-step explanation:
Given: The diameter of the bike wheel is 19 inches.
We need to find the circumference of the wheel.
The circumference of the wheel = πd
π = 3.14 and d = 19
Now plug in these values in the above formula, we get
The circumference of the wheel = 3.14*19
= 59.66 inches
We need to find number of revolutions of wheel to cover the distance of 500 feet.
Now we have to convert 500 feet to inches.
1 foot = 12 inches.
500 feet = 500 *12 = 6000 inches.
The number of revolution = 6000 / 59.66
= 100.56
When we round of to the nearest whole number, we get 101
To cover the distance of 500 feet, the wheel must be rotate 101 times.
Right triangle. You can tell because of the tiny square in the corner. This indicated that angle is equal to 90°. Any triangle that has 90° is a right triangle
Answer:
Undefined
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
0-(-3)/1-1
3/0
Since the denominator is 0, the slope is undefined.
Best of Luck!
Answer:
2.25
Step-by-step explanation:
Put the ages in each list in order from smallest to largest.
Smith: 62, 63, 63, 64, 64, 65, 66, 66, 67, 68
Thompson: 75, 76, 76, 77, 78, 78, 79, 80, 80, 81
Find the mediant (number in the middle of the sorted list). There are 10 numbers in each list, so average the 5th and 6th numbers because they are nearest the middle.
Smith: (64 + 65)/2 = 64.5
Thompson: (78 + 78)/2 = 78
The difference between the medians is 78 - 64.5 = 13.5
The range (the difference between smallest and largest age) is 6 for each of the two lists.
13.5 = (multiplier)(6)
multiplier = 13.5 / 6 = 2.25
