Answer:
37.699 cubic inches of water
Step-by-step explanation:
Volume of a cone is V= 1/3 pi r^2 h
We are given that the height is 5 in and the radius is 2 in.
Plug that into the formula: V= 1/3 pi 2^2 9
1/3 x 4 x 9 = 12
Now we are left with 12 pi.
Use a calculator and multiply 12 by pi to get:
37.699
Tan x =opposite/ adjacent =9/5
x= arctan(9/5)≈61
Answer:
Step-by-step explanation:
Making more than $150
Let the amount to be made be x.
Then: x+$150 will be the amount needed to be made
Let's assign variables
The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x
</span>
<span>y varies inversely as x
so that:
where k is the proportional constant
To calculate the value of k, plug in the values of x and y:
x=7
y=4
Now, write down the relation between x and y:
"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
So it would take 9 hours and 20 minutes to have this job done.
