Answer:
The volume of the cone is 
Step-by-step explanation:
The given cone has a radius of 10 cm and and height of 9 cm.
The volume of a cone is given by:
We substitute r=10 and h=9 , 
to obtain:
Simplify exponents to get:
Simplify:
Therefore the volume of the cone is
Answer:
Let number of cans collected by Shane =S
Number of cans collected by Abha=S+178
As, it is given that ,Abha collected 178 more cans than Shane did.
Also, the statement about inequality is
Both Shane and Abha have to collect no less than 2000 cans for recycling.
Writing the statement in terms of inequality
S +S+178 ≥ 2000
2 S ≥ 2000 - 178
2 S ≥ 1822
Dividing both sides by 2, we get
S≥ 911
So, Shane must have collected At least 911 cans.
Answer:
4.
Step-by-step explanation:
Since Eve has already knitted nine scarves we just need to add of few more. Our equation is this: 9 + _ + _ = ?
If you do 9 + 4 + 4, you get 17. Therefor, Eve must knit four scarves per day to meet her goal.
Answer:
slope = 2
Step-by-step explanation:
To find the slope, we need to read 2 points off the graph.
Where the line crosses the y-axis, the point is (0, 2.5).
The next point up on the line looks like (1, 4.5).
slope = m = (difference in y)/(difference in x)
To find the difference in y and difference in x, subtract the y-coordinates and the x-coordinates, respectively, in the same order.
difference in y = 4.5 - 2.5 = 2
difference in x = 1 - 0
slope = m = (difference in y)/(difference in x) = 2/1 = 2
