Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.
Answer:
10%
Step-by-step explanation:
Using the given formula with the given data, we have ...
efficiency = output work / input work
= (10 J)/(100 J) = 0.10 = 10%
Answer:
A: 12/7
Step-by-step explanation:
Hello!
<h2>Answer: </h2>
23. 138 people voted for Nyemi, 69 people voted for Luke, and 23 people voted for Natalie.
24. Reina did not ride 11/16 of the rides.
<h2>
Explanation:</h2>
23:
3 ÷ 5 = 0.6
230 × 0.6 = 138
230 × 0.3 = 69
230 × 0.1 = 23
24:
We know that Alberto rode 5/8 of the rides at the park, and Reina rode half of this.
5/8 × 1/2 = 5/16
16 - 5 = 11
The line of best fit is a line on a scatter plot graph with equal number of points on either side of it, it is the equivalent of average.
the line of best fit on your graph predicts the average score of a student who studies for 2 hours is 16
