Answer:

V = 1250π/3 mm³

V = 1309 mm³

Step-by-step explanation:

The composite figure is made up of a cylinder with radius 5 mm and two hemispheres of radius 5 mm. The height of the cylinder is

20 mm - 5 mm - 5 mm = 10 mm

The two hemispheres make up a full sphere of radius 5 mm.

V = πr²h + (4/3)πr³

V = π(5 mm)²(10 mm) + (4/3)π(5 mm)³

V = [(25 mm²)(10 mm) + (4/3)(125 mm)³]π

V = [250 mm³ + 500/3 mm³]π

V = 1250π/3 mm³

V = 1309 mm³

The sum of four consecutive integers is 134. Find the integers. (please show your work)
lidiya [134]

Answer:

Integers: 32,33,34,35

Step-by-step explanation:

Consecutive means back-to-back, with a difference of 1

Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum

x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32

Therefore since x = 32, all four integers are:

32,33,34,35

If we check this, we can see that their sum equals to 134

32+33+34+35 = 134

Hope this helps!

1. What is the coefficient of x in the division (18x^3 + 12x^2 – 3x) / 6x^2?
lubasha [3.4K]
Well since we're dealing with the co-efficient of x, then we just have to talk about 18x^3 and divide it by 6x^2 and we get 3x. so the co-eff. is 3 so (A)
