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.
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)
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

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.
