Answer: 14 females

Step-by-step explanation:

Let number of males = x +7

Let number of females = x

Set up the equation:

x + x + 7 = 35

2x + 7 = 35

2x = 28

x = 14

There are 14 females.

Answer:

Male=21 Female=14

Step-by-step explanation:

So the problem would be (f)+(f+7)=35

first you would subtract 7 from 35

Now you have (f)+(f)=28 or 2f=28

Then you divide both sides by two

f=14

and since we know there is 7 more males then the answer is

m=21

Say that you (or your parents) are purchasing a new car for $22,358. The sales tax is 6.45%, the down payment is 10% of the tota

Nastasia [14]

Answer:

(a) $133.88

Step-by-step explanation:

The addition of tax multiplies the purchase price by 1+6.45% = 1.0645. The payment of the down payment means the loan amount will be only 1-10% = 0.90 times the amount with tax. So, the loan amount is ...

$22,359(1.0645)(0.90) = $21,420.08

The loan is a secured loan (secured by the vehicle). So, the interest charged is that for a poor credit rating: 7.5%.

One month's interest is ...

I = Prt . . . . . interest on principal P at rate r for t years (1 mo = 1/12 yr)

I = $21,420.08(0.075)(1/12) = $133.88

The sum of the measures of the interior angles of a polygon with n sides is

defon

ANSWER

$(n - 2) \times 180 \degree$

EXPLANATION

The sum of the interior angles of a triangle is 180°

We can rewrite this as:

$1 \times 180 \degree = (3 - 2) \times 180 \degree = 180 \degree$

The sum of interior angles of a quadrilateral is 360°

We can also rewrite this as:

$2 \times 180 \degree = (4- 2) \times 180 \degree = 360 \degree$ In general an n-sided polygon has

the sum of the interior angles given by the formula:

$(n - 2) \times 180$
