Sarah earns $400 per week and spends 15% of her earnings on transportation. How much does Sarah spend on transportation every week? *

Answers

Answer:

60 dollars a week.

Step-by-step explanation:

Just take 15 percent of 400, then you get your answer

think of it like this: ?/400$ = 15/100. We are trying to find 15 % of 400, so that’s what the “?” represents.
thinking of it like fractions, cross multiply the numbers you have in this situation (400x15) =6,000
then you divide that answer by the number left (100)
(6,000 / 100) = 60

So the answer is 60$, 15% of 400$ is 60$

solve the system of equations -4x- y = -18 and 2x + 3y = 24 by combining the equations

Answers

Answer:

x = 3

y = 6

Step-by-step explanation:

-4x- y = -18

2x + 3y = 24 (Multiply everything by 2)

-4x - y = -18

4x + 6y = 48

5y = 30

y = 6

-4x- y = -18

-4x - 6 = -18

-4x = -12

x = 3

Which equation has the same solution as x^2 - 8x - 15 =3

Answers

Answer:

x^2 - 6x -18  is the same so you can write

x^2 - 6x -18   = ( x^2 - 8x - 15 = 3)

Step-by-step explanation:

When we subtract 3 each side we get -18  as -15 -3  is -18

x^2 - 6x -15 = 3

x^2 - 6x -15- 3 =  

x^2 - 6x - 18 = 0

When equations equal or set equal to zero we can then use the quadratic formula found in your book.

x1  

= −(−8) − √ (−8)2 − 4×1×(−18)  /  2×1

= 8 − 2 × √ 34  

/2

≈ −1.831

x^2  

= −(−8) + √ (−8)2 − 4×1×(−18)  

/2×1

= 8 + 2 × √ 34 /  2

≈ 9.831

What is the POINT in this equation y+5= 9/4 (x+25) *

Answers

Answer:

The vertex (your "point") is (-25, -5).

Step-by-step explanation:

Compare the given equation to

y - k = m(x - h).  We see that the slope, m, is 9/4; the x-coordinate of the vertex is h = -25, and the y-coordinate of the vertex is k = -5.

The vertex (your "point") is (-25, -5).

how do I work it out ?

Answers

Answer:

x - y = 5

Explanation:

As you can see in the first problem the ration is x to y = 8 to 3. This means for every 8 x values, there are 3 y values. Therefore, x - y should be the same as 8 - 3, which is 5.

Slope of the line pls helpppppp

Answers

Answer:

[tex] slope(m) = \frac{3}{2} [/tex]

Step-by-step explanation:

Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):

Where,

[tex] (-14, 3) = (x_1, y_1) [/tex]

[tex] (-12, 6) = (x_2, y_2) [/tex]

Plug in the values

[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]

[tex] m = \frac{3}{2} [/tex]

Answers

Answer: A) 20.9 ; B) 34years

Step-by-step explanation:

Given the following :

AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23

FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1

A)

MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY

F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]

= 38 + 60 +21 + 88 + 23 = 230

SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11

MEAN(X) = 230 / 11

X = 20.9

B)

WHEN A NEW PLAYER WAS ADDED :

MEAN (X) = 22

Let age of new player = y

Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y

Number of players = 11 + 1 = 12

Mean(x) = sum of ages / number of players

New mean (x) = 22

x = (230 + y) / 12

22 = (230 + y) / 12

Cross multiply

264 = 230 + y

y = 264 - 230

y = 34 years

The Jacksons are taking out a $35,000 loan to remodel their home. The tables below show the rates for a 1-year and 5-year loan from two different lenders. Complete each table to calculate the total repayment and interest paid for each loan offer.

Answers

Answer:

look at the screenshot

Step-by-step explanation:

look at the screenshot

The table for total repayment and interest paid for each loan offer:

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

What is simple interest?

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Formula;    Simple Interest(I) =  P × R × T/100

For the 1-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)

                                                               = $37,275

Total interest paid = $37,275 - $35,000

                               = $2,275

For the 5-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest

                            = $35,000 + (0.082 x $35,000 x 5)                

                            = $41,570

Total interest paid = $41,570 - $35,000 = $6,570

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570
