Answer: 13\sqrt{7}

Step-by-step explanation:

In the simple radical form there are no square root is remain to find.

Since, the given expression,

5\sqrt{28} + \sqrt{63}

5\sqrt{4\times 7} + \sqrt{9\times 7}

5\sqrt{4} \times \sqrt{7} + \sqrt{9}\times \sqrt{7}

5\times 2 \times \sqrt{7} + 3\times \sqrt{7}

10 \sqrt{7} + 3\sqrt{7}

(10 + 3)\sqrt{7}

13\sqrt{7}

Since, we do not need to find further square root of 7.

Thus, the required radical form of 5\sqrt{28} + \sqrt{63} is 13\sqrt{7}.

Answer:

13\sqrt{7}

Step-by-step explanation:

5\sqrt{28} +\sqrt{63}

To simplify the given expression we simplify each radical

5\sqrt{28} = 5\sqrt{4*7} = 5*2\sqrt{7} =10\sqrt{7}

\sqrt{63} = \sqrt{9*7} =3\sqrt{7}

5\sqrt{28} +\sqrt{63}

10\sqrt{7}+3\sqrt{7}

13\sqrt{7}

Can you determine what number x represents from the information given? Explain how you got your answer.
masya89 [10]

Answer:

x = 25

Step-by-step explanation:

75 (total amount of people that run) minus 40 (amount of people that lift weights and run) equals 35 (amount of people that run but don't lift weights)

120 (total amount of people surveyed) minus 65 (total amount of people that lift weights) equals 55 (total amount of people that do not lift weights)

55 (total amount of people that do not lift weights) minus 35 (total amount of people that run but don't lift weights) equals 25 (total amount of people that don't run or lift weights.

Gina was earning $10 per hour. Then she received a 10% pay rate increase. Next month, her pay rate will decrease by 10%. What wi
forsale [732]

Answer:

$9.90 per hour

Step-by-step explanation:

This month:

Initial pay: $10 per hour

% raise : 10%

Dollar amount of raise = 10% x $10

= 10/100 x 10 = $1

Gina's pay after the raise = $10 + $1 = $11 per hour

Next Month:

Starting pay: $11 per hour

% decrease : 10%

Dollar amount of decrease = 10% x $11

= 10/100 x 11 = $1.10

Gina's pay after decrease = $11 - 1.10 = $9.90 per hour

Roger is building a storage shed with wood blocks that are in the shape of cubic prisms. Can he build a shed that is twice as hi
Fynjy0 [20]

Given that Roger is building a storage shed with wood blocks that are in the shape of cubic prisms.

cube is basicallye a box which is made of squares. That is all the sides (lenght, width and height) are equal.

Now we have to determine, Can he build a shed that is twice as high as it is wide.

that means if width is 1 then height should be twice which is 2.


yes that is possible if we put one cubical prism over another cubical prism. then height of shed due to two prism will be twice than the width.

Hence correct choice should be "A. Yes. For every block of width, he could build two blocks high."

AysviL [449]

Answer

Social security tax amount = $3348

Medicare tax amount = $743

Step by step explanation

The amount earned by Marcus = $54000

Social security tax = 6.2% = 6.2/100 = 0.062

Social security tax amount = 54000*0.062

Social security tax amount = $3348

Medicare tax = 1.45% = 1.45/100 = 0.0145

Medicare tax amount = 54000*0.0145

Medicare tax amount = $743

Hope this will help you.
