12/6 = 2
700/2 = 350
There are double the amount of workers so it is half the time.

p + 2 = 5 ==> p = 3

3p + 2 = p + 3 ==> 2p = 2 ==> p = 1

3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)

2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2

d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2

W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.

Trzecie zadanie to tylko połączenie dwóch pozostałych.

Simplify. Remove all perfect squares from inside the square root. 12 = 12

Elena L [17]

Answer:

Removing the perfect square 4 in 12 we get 2√3

Step-by-step explanation:

The square root of 12 is

√12 = √(4 x 3)

√12 = 2√3.

There's no special trick here, but it's usually easy to check whether a small number is divisible by 4. Keep this in mind when looking for factors.

Removing the perfect square 4 in the square root of 12 we get 2√3.

Here 4 is a perfect square it can be written as

√4 =√2^2

√4 =2

What is the volume of a cylinder with a radius of 7 feet and a height of 12 feet? Use 3.14 for pi. Round your answer to the near

mylen [45]

Given :-

Radius of cylinder is 7ft.
Height is 12ft .

To Find :-

The volume of the cylinder .

Solution :-

As we know that the volume of the cylinder is ,

$\longrightarrow$ Volume = πr²h

On substituting the respective values ,

$\longrightarrow$ Volume = 3.14 * (7ft)²*12ft

$\longrightarrow$ Volume = 3.14*49ft²*12ft

$\longrightarrow$ Volume = 1846.32 ft.³

Hence the required answer is 1846.32 ft³.
