Your question implies there are choices given with possible answers. As I do not have those in front of me, I will show you how to simplify the radical. It is likely that the answer you seek is the simplified radical.

To simplify \sqrt{50 a^{6}  b^{7} } we use the following identity: for positive values of a and b, \sqrt{ab}= \sqrt{a}  \sqrt{b}

That identity allows us to re-write what we are given as \sqrt{50} \sqrt{ a^6 } \sqrt{b^{7}. Let us now consider each of these separately.

Though 50 is not a perfect square it can be written as 25 x 2 and 25 is a perfect square. Thus, we obtain \sqrt{50}= \sqrt{25} \sqrt{2}=5 \sqrt{2}

Next we consider a^{6} which is a perfect square as it is equal to (a^{3})  (a^{3}). Thus, \sqrt{a^{6}} = a^{3}

Lastly, we consider b^{7} which can be written as (b^{1})( b^{6}) and since b^{6} is a perfect square we obtain the following: \sqrt{b ^{7} } =\sqrt{b ^{1}} \sqrt{b^6} = b^{3}  \sqrt{b}

Putting that all together we obtain \sqrt{50 a^{6} b^{7} }=25a ^{3}b ^{3} \sqrt{2b}

At the season finale, you present the winner of Canadian Superstar with a recording-and-tour contract. The contract states that
Zina [86]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Winner is paid :

Monthly pay while on tour = $5000

Pay per CD sold =. $2

A) Equation which relates total earning in terms of number of months 'm' while on tour and the number 'n' of CD's sold.

(Monthly pay * number of months) + (pay per CD * number of CD's)

Earning = 5000m + 2n

B) How much will the winner earn after the first month if 500 CDs are sold?

m = 1, n = 500

5000(1) + 2(500) = $6000

C) Suppose after the third month on tour the new recording artist has earned a total of $74 000. How many GDs were sold?

m = 3

74000 = 5000(3) + 2n

74000 = 15000 + 2n

74000 - 15000 = 2n

59000 = 2n

n = 59000 / 2

n = 29500 CD's

D) In Canada, a record album or CD achieves gold status once it seLls 50 000 units. How much will the artist make if the CD goes gold after 6 months of touring?

n = Gold = 50000 ; m = 6

5000(6) + 2(50000)

30000 + 100000 = 130,000

The perimeter of a rectangle is 24. If the length is 5 times the width, what is the area?
KATRIN_1 [288]

Answer: Area is 20

Step-by-step explanation:

Perimeter of a rectangle is 24

Let the length be x

Let the breadth be Y

Length is 5times the breadth

I.e

X=5y

Formula for perimeter of a rectangle is

2(length + breadth)

= 2(x+y)

Substitute for x=5y

2(5y+y)=24

2(6y)=24

6y=24/2

6y=12

Y=12/6

Y=2

Breadth = 2

Since length =5y

Length=5(2)

Length = 10

Area of a rectangle = length × breadth

Area= 10×2

Area = 20

Area of the rectangle is 20

Thirty seven divided by nine
Sunny_sXe [5.5K]

Answer:

4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))

Step-by-step explanation:

To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.

To solve it through long division,

9 can go into 3 zero times

9 can go into 37 four times though

9*4 is 36

So subtract 36 from 37, leaving 1.

9 can go into 1 zero times.

Add a zero behind the one and 9 can go into 10 once.

The pattern continues forever, making the answer 4.1(with the one repeating)

or 4.11 (rounded to the hundredth place)

If you need anymore clarification I can certaintly help.
