What material is Kazoo made from?
shusha [124]

Answer:

Most kazoos are made from thermoplastics, which are more rigid and durable. Different types of plastics used to make the body of a kazoo include polypropylene and high-density polyethylene (HDPE). To make these materials easier to work with, fillers, which change the properties of the plastic, are often added.

Which radical expression represents the difference between the expressions 4 50 + 4 12 − 2 27 and 2 3 ? A) 20 2 B) 20 2 − 2 3 C)
Tcecarenko [31]

Answer:

A 20 sqrt(2)

Step-by-step explanation:

4 sqrt(50) + 4 sqrt(12) - 2 sqrt(27)  minus 2 sqrt(3)

We know that sqrt(a) sqrt(b) = sqrt(ab)

this is the first expression

4 sqrt(25)sqrt(2)  + 4 sqrt(4)sqrt(3) - 2 sqrt(9)sqrt(3)

4*5sqrt(2) + 4*2 sqrt(3) - 2*3 sqrt(3)

20 sqrt(2) +8 sqrt(3)-6sqrt(3)

20 sqrt(2) +2 sqrt(3)

Now we subtract 2 sqrt(3) from the above expression

20 sqrt(2) +2 sqrt(3)  - 2 sqrt(3)

20 sqrt(2)

Please help I have no idea how to do this!!!
Ronch [10]

Answer:

You have to graph and label the points

Step-by-step explanation:

3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle

-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4

2 is just a horizontal line starting at (closed circle) 4, it is greater than also.

If you don't understand the the constants (the numbers on their own) just a vertical translation.

If the cross either the x or y axis, you have to find that too, im pretty sure.  

To find the y axis intercept, make x = 0 and solve for y

and to find the x axis intercept, make y = 0 and solve for x

at franklin middle school,3/8 of the students take a bus to school, 3/5 walk, and the rest bike. There are 20 students who bike
nordsb [41]

Answer:

There are 800 kids in the school.

Step-by-step explanation:

Let x be the answer (how many kids are in the school).

Let's add them together. 3/5+3/8 = how many people do not bike to school, which is 0.975 of everyone. 1-0.975 = 0.025, which means 0.025x = 20. 0.025x = 1/40, so 1/40x = 20. Multiplying, we have x =800.
