Answer:
80%
Step-by-step explanation:
First, you multiply 20 by 5, which gives you 100. Then multiply 16 by 5, which is 80. 80 out of 100 is 80%
It doesn't have a formal name. However, since a fraction is division, you can call it a quotient.
Answer:
A: y < -2x - 1
Step-by-step explanation:
First, to figure out which part of the graph to be looking at, you will look at the shaded region as the solution area.
So, the solution area is to the left of the line. Said line is a dotted line which means that the points on the line can not be a solution.
If the points on the line can not be a solution then it eliminates answer choices C and D because y can not equal the other side of the inequality.
Now, we will bring the shaded region back into focus to find out if y is greater than or less than the other side. The shaded area is "below" the line so it is less than -2x - 1.
To ensure this is correct, plug two points into the inequality we just chose, one from the shaded region and one not, just to make sure the answer is correct.
I picked (-3,4) to test. So plug them into the inequality to get:
4 < -2 (-3) - 1
So 4 < 6 - 1 which is correct.
Then from the other side of the line I picked (5,2)
2 < -2 (5) - 1
2 < -10 - 1
2 < -11 is not true so the inequality that we found was correct.
Answer:
about 26.6 times
Step-by-step explanation:
The circumference of the ball is found from ...
C = 2πr = 2π(4.3 in) ≈ 27.02 in
There are 12 inches per foot, so the 60 foot distance of interest is ...
(60 ft)×(12 in/ft) = 120 in
In terms of ball circumference, that distance is ...
(120 in)/(27.02 in/rotation) ≈ 26.6 rotations
If the ball starts rotating at the foul line, it will turn about 26.6 times before reaching the head pin.
