What is the square root 6n carried to the power of 2/3 in radical form
BaLLatris [955]

Answer: \sqrt[3]{6n}

Step-by-step explanation:

We have the following expression:

(\sqrt{6n})^{\frac{2}{3}}

Which can be written as follows:

((6n)^{\frac{1}{2}})^{\frac{2}{3}}

Multiplying the exponents:

(6n)^{\frac{1}{3}}

Writing in radical form we finally have the result:

\sqrt[3]{6n}

The small rectangle was enlarged to create the big rectangle.
kow [346]

Answer: the missing measure on the big rectangle is 30 feet.

Step-by-step explanation:

If the small rectangle was enlarged to create the big rectangle, it means that they are similar. This also means that the dimensions of the larger rectangle different form the dimensions of the smaller rectangle by a constant ratio or factor.

The smaller rectangle has a length of 12 feet and width of 2 feet. The larger rectangle has a length of x feet and width of 5 feet. This means that

x/12 = 5/2

Cross multiplying, it becomes

2x = 12 × 5 = 60

x = 60/2 = 30

During the first four months of the year, Jack earned $1270, $1150, $870 and $1450 If Jack must have an average salary of at lea
tia_tia [17]

Answer:

1010

Step-by-step explanation:

There are a whole class of questions that rely on the method to this one.

First add up what you know

1270 + 1150 + 870 + 1450 = 4740

Now add on the 5th month (which you don't know. Call it x)

4740 + x

Divide by 5

(4740 + x)/5 = 1150 and that is your equation    

Solution

Multiply both sides by 5

5*(4740 + x) / 5 = 1150 * 5

4740 + x = 5750

Subtract 4740 from both sides

4740 - 4740 + x = 5750 - 4740

x = 1010

Which seems kind of low, but that's what the numbers come to.
