The gardener can rake 5 lawns in 7.5 hours
Answer:
x=-5.143 or
Step-by-step explanation:
Subtract 75 from 3 and you get -72
-72=4x
x=-5.143
Answer:
4.52 x 10
Step-by-step explanation:
45.2 in scientific notation, move the point one place to the left , it becomes
4.52 x 10
Answer:
Slope: 3/4
Step-by-step explanation:
If you want the equation for the line:
y = (3/4)x - 1
However, this is how you find the slope:
You want to find any two point on the graph, however, it's easier if it touches exactly where two number meet. For example I chose:
(0,-1) and (2,4)
Now just find the change in y, and divide it by the change in x
change in y = 3
change in x = 4
So your slope is 3/4
The formula for the volume of a cone is ...
... V = (1/3)πr²h = (1/3)π(d/2)²h = (π/12)d²h
for height h and diameter d.
Then the volume of the cone is ...
... V = (π/12)·(2 in)²·(4 in) = 4π/3 in³ ≈ 4.189 in³
___
The formula for the volume of a cylinder is ...
... V = πr²h = π(d/2)²h = (π/4)d²h
Then the volume of the cylinder is ...
... V = (π/4)·(2 in)²·(6 in) = 6π in³ ≈ 18.850 in³
_____
The difference in volume is ...
... 18.850 in³ - 4.189 in³ = 14.661 in³ ≈ 14.7 in³
