The width of the rectangle is equal to the greatest common monomial factor of 6n^4, 20n^3,6n 4 ,20n 3 ,6, n, start superscript, 4, end superscript, comma, 20, n, cubed, comma and 14n^214n 2 14, n, squared. What is the length and width of the rectangle?

Answers

Given:

Area of rectangle = [tex]6n^4+20n^3+14n^2[/tex]

Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex].

To find:

Length and width of the rectangle.

Solution:

Width of the rectangle is equal to the greatest common monomial factor of [tex]6n^4, 20n^3,14n^2[/tex] is

[tex]6n^4=2\times 3\times n\times n\times n\times n[/tex]

[tex]20n^3=2\times 2\times 5\times n\times n\times n[/tex]

[tex]14n^2=2\times 7\times n\times n[/tex]

Now,

[tex]GCF(6n^4, 20n^3,14n^2)=2\times n\times n=2n^2[/tex]

So, width of the rectangle is [tex]2n^2[/tex].

Area of rectangle is

[tex]Area=6n^4+20n^3+14n^2[/tex]

Taking out GCF, we get

[tex]Area=2n^2(3n^2+10n+7)[/tex]

We know that, area of a rectangle is the product of its length and width.

Since, width of the rectangle is [tex]2n^2[/tex], therefore length of the rectangle is [tex](3n^2+10n+7)[/tex].

depth of water in a swimming pool decreases by 1/8 inch per day do to evaporation no water is added to the pool for a two week. What is the total change in depth of the water during this time period?

Answers

Answer:

7/4

Step-by-step explanation:

its 7/8 because if it goes down 1/8 each day count that for 2 weeks which is 14 days so it would be 14/8 or 7/4

HOPED THIS HELPED!!!!!!! :D

The total change in depth of the water during this time period is 7/4 in

What is subtraction?

To subtract means to take away from a group or a number of things.

Given that, the depth of water in a swimming pool decreases by 1/8 inch per day do to evaporation, no water is added to the pool for a two week.

The reduce in the pool in 1 day is 1/8 inch.

So, for 2 weeks, it's 14 days, therefore, in 14 days it will reduce = 1/8x14 = 7/4 in

Hence, The total change in depth of the water during this time period is 7/4 in

In a bag full of beans and rice, the ratio by weight of beans to rice is 2 to 9. If the bag has a total weight of 3 kilograms, how many kilograms of beans are there in the bag? (round to nearest thousandths)

Answers

Answer: 0.667 kilograms

Step-by-step explanation:

From the question, we are informed that in a bag full of beans and rice, the ratio by weight of beans to rice is 2 to 9.

If the bag has a total weight of 3 kilograms, the amount of kilograms of beans that are there in the bag will be:

= 3/9 × 2 kilograms

= 6/9 kilogram

= 0.667 kilograms

Step-by-step explanation:

We know that it costs 37 cents to mail a letter that weighs 1 oz or less. This would mean that for x ≤ 1, P(x) should equal 37. Already, we can eliminate A and D.

We also know that it costs an additional 26 cents for at most another ounce added to the original 1 ounce. This means that for 1 < x ≤ 2, P(x) = 26 + 37 = 63. This is shown by B.

Thus, the answer is B.
