x=5

x = 5.

Step-by-step explanation:

2x + 1 = 11

Subtract 1 from both sides:

2x = 11 - 1 =10

Divide both sides by 2:-

x = 10/2

The volume of a sphere is 500
3
πcm3. What is the radius?

Step-by-step explanation:

The volume of a sphere is 500 3 πcm3. what is the radius? sphere v = 4 3 πr3 1. substitute value into formula:   500 3 π = 4 3 πr3 2. undo multiplication of 4 3 :     125π = πr3 3. undo multiplication of π:     125 = r3 4. undo cube:          3√125 = r the radius of the sphere is 6 ⇒ 5 cm

Step-by-step explanation:

The equation for the volume of a sphere is V= . So, to solve this problem we will plug in 500 for V and solve for the radius, .

1. 500=
2. Multiply both sides by 3:
3. Divide both sides by 4:
4. Divide both sides by :
5. Find the cubed root of both sides:
6. The radius is about 4.9 cm

150% of 66(Need the work shown)

Change 150% into a decimal by multiplying it by 100.
150(100)= 1.50
Now multiply 1.50(66)= 99
66 is the 100%
we can solve this problem by the rule of three.

Therefore:
66------------------------100%
x--------------------------150%

x=(66 * 150%) / 100%=99

Answer 150% of 66 is 99.

Other method:
150% of 66=1.5 *66=99

Answer: 150% of 66 is 99.

How many 84s are in 672

There are 8 times 84s that are present in 672.

### How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find how many 84s are present  in 672

We will simply divide the 84 by 672.

That is;

672/ 84

= 336/42

= 168/21

= 8

Hence, there are 8 times 84s that are present in 672.
