You and your soccer team are interested in buying jerseys. The price of each jersey is $50. If you buy 4 jerseys, you will get 10% discount. How much do you have to pay if you buy 8 jerseys?

Answers

Answer: $4.84

Explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84

Fill in the blank. In the triangle below, zº = ___º

Answers

Answer:

[tex]\huge\boxed{43 \textdegree}[/tex]

Step-by-step explanation:

We can use basic angle relationships to find the measure of z.

We know that all angles in a triangle will add up to 180°. Since we already know two out of the 3 angles (47° and 90° - right angles are always 90°) we can add those two up and subtract from 180 to find out the missing angle length.

Based on the after-tax retums, at what federal tax rate (as shown in Chapter 4) is an investor better off choosing a tax-exempt 7 16 percent municipal bond over a
taxable 10.39 percent corporate bond?
The after-tax retum on the corporate bond when the tax rate is 10% is %

Answers

Answer:

The after-tax rate for the Corporate Bond when the tax rate is 10% is 9.35%

Step-by-step explanation:

The investor is better of at any rate above 30%, i.e 31% of tax rate would give the investor 7.1691% return ( 10.39  −  ( 10.39  ⋅  31 % ) )

Thus the return from the tax exempt municipal bond would be higher than the return from the taxable corporate bond.

The after-tax rate for the Corporate Bond when the tax rate is 10% is 9.35%( 10.39  −  ( 10.39  ⋅  10 % ) )

Indicate the equation of the given line in standard form. The line with slope 9/7 and containing the midpoint of the segment whose endpoints are (2, -3) and (-6,5).​

Answers

Given parameters:

Coordinates of end points =  (2, -3) and (-6,5).​

 Slope of line  = [tex]\frac{9}{7}[/tex]

Unknown:

Equation of the line with the given slope = ?

Solution:

Let us find the coordinates of the mid-point of the line given.

   Since the end points are (2, -3) and (-6,5);

   Midpoint;

            x, y = [tex]\frac{x_{1} + x_{2} }{2}[/tex] , [tex]\frac{y_{1} + y_{2} }{2}[/tex]  

            x, y = [tex]\frac{2 + (-6)}{2}[/tex]  ,  [tex]\frac{-3 + 5}{2}[/tex]   = -2 , 1

The coordinate of the mid point = -2,1

Equation of a line is;

                  y = mx + c

x and y are the coordinates

     m is the slope

     c is the y intercept

We need to find c in order to fully develop our equation;

             y = mx + c

              y = 1 , x = -2 and m = [tex]\frac{9}{7}[/tex]

So,

           1 = [tex]\frac{9}{7}[/tex] x (-2) + c

            c  = 1 + [tex]\frac{18}{7}[/tex]   = [tex]\frac{25}{7}[/tex]

Now, the equation of the line is;

              y = -2x + [tex]\frac{25}{7}[/tex]  

Multiply through by 7,

            7y = -14x + 25

The equation of the line is 7y = -14x + 25

7 +2×5

17 $cost 1 quesadilla and 10 burritos

Answer:

Select the smallest fraction from the following fractions.
2/4, 3/6, 1,3, 7/9

Answers

7/9 is the smallest fraction

Answer: 1/3

Step-by-step explanation:

2/4 and 3/6 can be simplified to 1/2.

1/3 is smaller than 1/2 because it have a larger denominator, but the same numerator.

Multiple 1/3 by 3/3 and you get 3/9, which is smaller than 7/9.  

5 times a number is 6 less than the square of that number

Answers

Answer:

5x = x^2 - 6

Step-by-step explanation:

a number can be represented by x,

5 times a number can be represented as the product of 5 and x, 6 less than the square of that number tells us that this is equal to a number squared minus 6. is tells us that these two expressions are equal.

If you want a working number, just solve by completing the square once this is in standard form. This is then converted to vertex form.

x^2-5x-6 = (x-5/2)^2-49/4 = (x^2-5x+25/4) -49/4 = x^2-5x-6.

(x-5/2)^2-49/4=0

(x-5/2)^2=49/4

(x-5/2) = ±√49/4

(x-5/2) = ±7/2

x=5/2±7/2

x=(5±7)/2

x=12/2,-2/2

x=6,-1

Thus, the number can either be 6 or -1.
