Answer:

Answer:

75 people.

Step-by-step explanation:

If Friday is x, then Saturday is 150 + x. The number of people on Sunday then is (Friday + Saturday)/2, thus (x + (150 + x))/2. This then simplifies to (x + 150 + x)/2 ---> (2x + 150)/2 ---> 2x/2 + 150/2 ---> x + 75. So, Friday is x and Sunday is x + 75, to find out how many more visitors the museum have on Sunday than Friday, you subtract the two numbers. (x + 75) - x = 75.

Find the slope of the line that passes through the points (-1, 1) and (2, 7).

Answer:

2 is your slope

Step-by-step explanation:

Find the slope. Use the slope-formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-1 , 1)

(x₂ , y₂) = (2 , 7)

Plug in the corresponding numbers to the corresponding variables:

m = (7 - 1)/(2 - (-1))

Simplify:

m = (6)/(2 + 1)

m = 6/3

m = 2

2 is your slope (or rise 2, run 1).

~

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (2, 7)

m = = = 2

Compare the models for 1/3 and 2/6 how dose the number of parts relate to the sizes of the parts

There is no model attached, but, we can imagine a model.

Take a whole pizza.

There’s six slices and you have three friends.

You want it to be even and so each friend gets two slices.

But, originally, the pizza could’ve been sliced into three bigger pieces anyways.

Todd has 2 frogs. This is 1/3 the number of frogs that heather has. How many frogs doEs heather have

She has 6 frogs because if Todd has 1/3 of the amount you do 2x3=6.

2x3=6 and thats the number of frogs heather has or you can do this tood has 2 frogs and heather has 1/3 more then take the 2 and add it to the 1 and that makes three. then take both of the threes and add them together and you then have the same number of 6

your primary jobs gross income is 3468.73/month deductions are fica (7.65%) federal tax witholding (11.5%) and state tax withholding (7.8%) how much are your ficed expenses if they are 36% of your relized income

Answer:

$912.21

Step-by-step explanation:

Your primary jobs gross income = $3468.73

All deductions 7.65% (fica) + 11.5% (federal) + 7.8% (state tax) = 26.95%

Income after deductions = 3468.73 - ( 26.95% × 3468.73 )

= 3468.73 - (0.2695 × 3468.73)

= 3468.73 - 934.82

= $2,533.91

Fixed expenses on your realized income = 36%

Fixed expenses = 36% × 2,533.91

= 0.36 × 2,533.91

= $912.2076 ≈ $912.21

Fixed expenses are $912.21

Sierah907 Your primary job’s gross income is $3,468.73/month. Deductions are FICA (7.65%), federal tax withholding (11.5%), and state tax withholding (7.8%). How much are your fixed expenses if they are 36% of your realized income?

$1,388.65

$814.92

$912.21

$1,068.57

To get your realized income you: add your deductions which equals to a total of 26.95%.

Then you subtract that amount from your gross income.

(3468.72 - 26.95% = 2533.91)

After that you need to find what 36% of your realized income equals to:

and it equals to, 912.20.

Therefore, your answer is C.

Answer 2:

our deductions are 7.65% , 11.5% and 7.8% . Total 26.95% .

So deduct that from your Gross . $3468.73 - 26.95% leaves you with $ 2533.91.

That's your Realized Income . $2533.91 .

So you need to find 36% of that . It's $912.20.

And that is your answer . Your fixed expenses are $ 912.20 .

If a = 2 + i, and b = 3 – 2i, whats b/a?

The result of the quotient b/a is 4/5 -7/5 i

Given the complex numbers a = 2 + i, and b = 3 – 2i, we are to get the value of the expression b/a by rationalizing

Rationalize the resulting quotient as shown:

Hence the result of the quotient b/a is 4/5 -7/5 i

B/a = (3 - 2i)/(2 + i)

To divide complex numbers, you multiply the numerator and denominator by the complex conjugate of the denominator.

The complex conjugate is 2 - i. ** Remember i^2 = -1 **a + bi

( 3 - 2i) ( 2 - i)

------------------- Foil numerator and denominator.

(2 + i) ( 2 - i)

6 - 3i - 4i + 2i^2 6 - 7i - 2 4 - 7i 4 - 7i

--------------------- ----------- ------- OR --- -----

4 - i^2 4 + 1 5 5 5

The answer can be written either way. If they specify real part and imaginary part, the second option is correct.
