The math worksheet.Thankyou.

Answer 1

Answer: Ok... I'm not going to give you answers but I'll help you.
Examples:

Example 1:
2-4(3x+5) --- distribute the -4 to the 3x+5 to get...
2-12x-45 ---- do 2-45
-43-12x
and that's your answer since you can't combine the -43 with the -12x cuz, the -43 does have a variable.

Example 2:
5y+4-2y ---- so simplify first. 5y-2y. to get...
3y+4
and that the answer

cuz you can't combine a number with a variable(letter. y, x, etc.) with one that doesn't.

I hope this helps. This is easy. Trust me. if you still don't get it. Just comment. Hope this helps! :)

If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter, what is the volume of the tank? Assume 3.14 for pi.

Answers

Volume of a cylinder = cross sectional area * height
so...
height = 3m
cross sectional area = pi × radius^2
radius = 1/2 diameter
radius = 1/2 × 6 = 3
3.14 × 3^2
= 3.14 × 9
= 28.26
therefore...
volume of cylinder = 28.26 × 3
= 84.78 m^3

volume = area of base x height
v=pi x radius^2 x height

v=3.14 x 3^2(6/2 because 6 is diameter so must divide by 2 for radius) x 3
v=84.78 m3

The fraction 3/10 is the difference of 8/10 and which fraction

Answers

Answer:

½ or 11/10

Step-by-step explanation:

3/10 = 8/10 - X

X = 8/10 - 3/10 = 5/10 = 1/2

Or,

X - 8/10 = 3/10

X = 11/10

Answer:

5/10

Step-by-step explanation:

8/10 -5/10 =3/10
