Answers

Answer 1

Answer:

Step-by-step explanation:

10.   To solve for this, use the formula: 180*(n-2)

So, 180(n-2) = 2,340

Once n is solved for, that is the number of sides

11. Use the formula:

[180*(n-2)]/n

    (n represents the number of sides)

12. Think of the sum of all interior angles in a quadrilateral

Which expression is equivalent to ( xy -6)2 for all values of x and y where the expression is defined?

Answers

Answer:

 ( x y -6)²  =  x² y² - 12 xy + 36            

Step-by-step explanation:

Explanation:-

Given that the expression ( x y -6)²

Apply formula (a-b)² = a² -2ab + b²

( x y -6)² = (xy)² - 2 × xy× 6 + (6)²

             = x² y² - 12 xy + 36

( x y -6)²  =  x² y² - 12 xy + 36

In the year 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the the year 1982 average. By what percent did chicken consumption increase from the year 1982 to the year 1984?

Answers

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

Answer:

I think it increased by 0.05.

Step-by-step explanation:

If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0

Solve the equation for y. Type out your steps to solve this problem as you are showing your work:
7(y + 3) = 5y + 8

Answers

Answer:

-13/2

Step-by-step explanation:

7(y+3)=5y+8

7y+21=5y+8

7y-5y+21=8

2y+21=8

2y=8-21

2y=-13

y=-13/2

Answer:

y = -6.5

Step-by-step explanation:

simplify: 7y+21=5y+8

put like-terms together and simplify: 2y=-13

(like-terms: 7y-5y=8-21)

divide both sides by 2: y=-6.5

Your job as a carpenter pays $20/hour and you worked 40 hours last week.

Then the amount that you earn in 40 hours will be

⇒ $20 x 40

⇒ $800

The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be

⇒ $800 - $83 - $19

⇒ $800 - $102

⇒ $698

The total amount of the check will be $698. Then the correct option is A.

The rate of the fruit is the ratio of apples to oranges. That is, the number of apples divided by the number of oranges into its simplest fraction form:

[tex]x = \frac{25\,apples}{10\,oranges}[/tex]

[tex]x = \frac{5\,apples}{2\,oranges}[/tex]

The rate of the fruit is 5 apples to 2 oranges.

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT
