Answer:
A. 16.8 in³
B. 28.3 m³
C. 65.4 in³
Step-by-step explanation:
The volume of a cone is given as:
V = ⅓ * pi * r² * h
Where r = radius of base of cone
h = height of cone
A. Radius = 2 inches, height = 4 inches
It's volume is:
V = ⅓ * pi * 2² * 4
V = 16.8 in³
B. Diameter of 6 m, and a height of 3 m
It's diameter is 6 m, therefore, it's radius is:
r = d / 2 = 6 / 2 = 3 m
It's volume is:
V = ⅓ * pi * 3² * 3
V = 28.3 m³
C. Diameter of 5 in, and a height of 10 in
It's diameter is 5 in, therefore, it's radius is:
r = d / 2 = 5 / 2 = 2.5 m
It's volume is:
V = ⅓ * pi * 2.5² * 10
V = 65.4 in³
Answer:
the graph is 1/2, y intercept is -6, last one in -7
Step-by-step explanation:
A box plot contains two dots placed at the ends of the data for the mininum and the maximum value with a line placed over the median.
Let's put the numbers in your set in order from low to high:
5
6
7
8
9
9
9
10
12
14
17
17
18
19
19
The median is the middle number. We have 15 numbers so we select the 8th number - 7 from each end. In this set, 10 is the median.
Only one box plot has dots at 5 and 19 and a median of 10 - choice B. Thus, B is the proper box plot.
Answer:
C.
Step-by-step explanation:
......................
<h2>We know:</h2>
You currently make $13.50 an hour. You've earned a 15% pay raise. You want to find out your previous rate of pay per hour.
<h2>Steps:</h2>
1.) Convert 15% to a decimal, which equals 0.15
2.) Multiply your current earnings with the percentage in decimal form (0.15)
$13.50 (current pay per hour) x 0.15 (percentage in decimal form) = $2.025 (difference between your previous wage and your current wage)
3.) Subtract the difference of your previous wage and current wage with your current earnings
$13.50 (current pay per hour) - $2.025 (difference between previous and current wage) = $11.475 (previous pay per hour)
4.) Since this is talking about wage, rounding is not applicable. In other cases, your number would be rounded off to $11.48, however you can't add what you don't have, so you would have to round down.
<h2>
You were previously making $11.47 an hour.</h2>
