Every year, Colton's grandmother knits him a cozy wool sweater for his birthday. Colton's favorite color is red, so she plans to buy 700 yards of thick red wool for his sweater this year. She chooses a wool that is sold in 420-foot skeins, or bundles. How many skeins should she buy?

Answer:

[tex]1/x^5[/tex]

Step-by-step explanation:

[tex]x^-^y = 1/x^y[/tex]

Answer:

1/x^5

Step-by-step explanation:

When you have a negative exponent, you have to put 1 over that power without the negative sign in the exponent. You put 1 over x^5

Answer: 1/x^5

Answer:

Thus, the original price of the pair of shoes was $100.

Step-by-step explanation:

Percentages

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40

Answer:

The required width of the field that would maximize the area is = 1250  feet

Step-by-step explanation:

Given that:

The total fencing length = 5000 ft

Let consider w to be the width and L to be the length.

Then; the perimeter of the rectangular field by assuming a parallel direction is:

P = 3L + 2w

⇒ 3L + 2w = 5000

3L = 5000 - 2w

[tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex]

Recall that:

The area of the rectangle = L×w

[tex]A(w) = ( \dfrac{5000}{3}-\dfrac{2}{3} ) w[/tex]

[tex]A(w) = \dfrac{5000}{3}w-\dfrac{2}{3} w^2[/tex]

Taking the differentiation of both sides with respect to t; we have:

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{2}{3} ( 2 w)[/tex]

[tex]A' (w) = \dfrac{5000}{3} - \dfrac{4w}{3}[/tex]

Then; we set A'(w) to be equal to zero;

So; [tex]\dfrac{5000}{3} - \dfrac{4w}{3}=0[/tex]

5000  = 4w

w = 5000/4

w = 1250

Thus; the required width of the field that would maximize the area is = 1250  feet

Also, the length [tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex] can now be :

[tex]L = \dfrac{5000}{3} - \dfrac{2(1250)}{3}[/tex]

L = (5000 -2500)/3

L = 2500/3 feet

Suppose, the farmer divides the plot parallel to the width; Then  2500/3 feet = 833.33 feet and the length L = 1250 feet.

Answer:

This is a rational decimal and is not a repeating decimal.

Answer:

56miles/hr

Step-by-step explanation:

Given parameters:

Time taken for the to travel  = 4hrs

Speed of the train  = 70mph

  From this data, let us find the distance of the trip;

Distance  =Speed x time

  Therefore, insert the parameters;

          Distance  = 70mph x 4hr = 280miles

Now;

  Return trip took, 5hrs,

Speed  = ?

  Speed  = [tex]\frac{distance}{time}[/tex]  

Insert the parameters and solve;

     Speed  = [tex]\frac{280}{5}[/tex]   = 56miles/hr

Answer:

20 pieces of rope

Step-by-step explanation:

Mr. Thompson has a 5-ft rope. If he cuts the rope into 1/4-ft pieces, that means for every foot, there are 4 pieces of rope. There are 5-ft of rope, so we multiply 5 and 4 to get the number of pieces of rope.

5 x 4 = 20 pieces of rope.

I hope that this helps! :)

umm let me look at this one more time then I will answer:)

Answer:

Step-by-step explanation:

Milk consumed in 4 weeks = 20 jugs

Milk consumed in 1 week = 20 ÷ 4 = 5 jugs

Milk consumed in 8 weeks = 5 * 8  = 40 jugs

2) Cost of 20 sets of crayons =  $ 60

Cost of 1 set of crayon  =   60 ÷ 20  = $ 3

Cost of 9 sets of crayons =  3 * 9 = $ 27

3) Number of tomatoes required to make soup for two guest  = 4

Number of tomatoes required to make soup for one guest  = 4 ÷ 2  = 2

Number of tomatoes required to make soup for 6 guests= 2*6= 12 tomatoes

Answer:

n = 9

Step-by-step explanation:

7n + 5 = 68

7n + 5 - 5 = 68 - 5

7n = 63

7n / 7 = 63 / 7

n = 9
