8 inches because 3.14*2^2*8=100.48 which is rounded to 100

Answer:

The approximate height of the bird feeder is 8\ in

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2}h

In this problem we have

V=100\ in^{3}

r=2\ in

substitute and solve for h

100=(3.14)(2^{2})h

100=12.56h

h=100/12.56=7.96=8\ in

The sum of two numbers is 3. Five times the larger number plus four times the smaller number is 29. Find the numbers
gulaghasi [49]
Let's have two numbers x (larger) and y (smaller). from the info above...

x + y = 3
5x + 4y = 29

so that means y=3 - x. we can sub this in
5x + 4(3-x) = 29
5x + 12 - 4x = 29
x = 17
then y=3-x=3-17=-14

so it's 17 and -14

6) What is 13% of 33.39?
icang [17]

Answer:

1. We assume, that the number 33.39 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 33.39 is 100%, so we can write it down as 33.39=100%.

4. We know, that x is 13% of the output value, so we can write it down as x=13%.

5. Now we have two simple equations:

1) 33.39=100%

2) x=13%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

33.39/x=100%/13%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 13% of 33.39

33.39/x=100/13

(33.39/x)*x=(100/13)*x       - we multiply both sides of the equation by x

33.39=7.6923076923077*x       - we divide both sides of the equation by (7.6923076923077) to get x

33.39/7.6923076923077=x

4.3407=x

x=4.3407

now we have:

13% of 33.39=4.3407
