I graphed it out and it seems that both A and C are correct. I would check them to make sure.
Answer:
108pi
Step-by-step explanation:
We do not need to know the height and radius, as the formula for the volume of a cone is just a third of the volume of a cylinder. So we have 36pi * 3 or 108pi.
Answer:
The answer is Ari, Beth, Cindy
Explanation
Ari
- 2¾ miles is 2.75 miles
- speed of 2½ miles per hour is 2.5 mi/h
DISTANCE = SPEED × TIME
t = d/s
= 2.75/2.5
= 1.1hr
= 66mins
Beth
- 1¾ miles is 1.75 miles
- speed of 1¼ miles per hour is 1.25 mi/h
t = d/s
= 1.75/1.25
=1.4hr
=84mins

(Correct me if i am wrong)
Answer:
D. H = 2.1t + 12
Step-by-step explanation:
Let us assume the t be the time in minutes
And h be the water level
Now before reaching to the equation that need to be used
before this, determine the inches per minute i.e.
= 54 inches - 12 inches
= 42 inches in 20 minutes.
Now for per minute, it would be
= 42 inches ÷ 20 minutes
= 2.1 inches per minute
After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12
So the equation is
H = 2.1t + 12
hence, the last option is correct
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is the equation of the line
To graph a line we need two points
<em>Find the intercepts</em>
1) The y-intercept is the value of y when the value of x is equal to zero
For x=0
The y-intercept is the point (0,3)
2) The x-intercept is the value of x when the value of y is equal to zero
For y=0
The x-intercept is the point (-1.5,0)
To draw the graph of the line plot the intercepts and join the points
using a graphing tool
see the attached figure
