A credit card company offers an annual 2% cash-back rebate on all gasoline
purchases. If a family spent $5,650 on gasoline purchases over the course of a year,
what was the family's rebate (in dollars) at the end of the year?|

Answers

$4,350 x 0.02 = $87

$360 - $87 = $273

Interest $270 no rebate

so $273 - $270 = $3

The family's rebate at the end of the year is $113.

What is a rebate?

A rebate is a form of buying discount and is an amount paid by way of reduction, return, or refund that is paid retrospectively. It is a type of sales promotion that marketers use primarily as incentives or supplements to product sales.

Given that, a credit card company offers an annual 2% cash-back rebate on all gasoline purchases.

A family spent $5,650 on gasoline purchases over the course of a year.

Now, rebate =2% of 5650

= 2/100 ×5650

= 0.02×5650

= $113

Therefore, the family's rebate at the end of the year is $113.

Step-by-step explanation:

5x + 2y - 4 = 0 and (15, - 21)

d = |(A*Px)+(B*Py)+C| / (sqrt A^ + B^2)

A=5, B=2, C= - 4 and Px=15, Py= -21

Answers

Answer:

Answer to the first part: 8a³b + 4ab

Step-by-step explanation:

Perimeter = distance around the three sides

P = 6a³b + 2a³b + 4ab

P = (6a³b + 2a³b) + 4ab add like terms

P = 8a³b +4ab Simply

The value of the perimeter and area of the triangle are,

20.52 cm² and 28.68 cm

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, By Using Pythagoras theorem to find the base of the triangle as;

a² = 6² - 3²

a ² = 27

a = √27

And, b² = 9² - 3²

b² = 72

b = √72

Hence, Base = √27 + √72

= 13.68

So, We get;

Area = 0.5 x 13.68 x 3

Area = 20.52 cm²

And, The value of perimeter is,

Perimeter = 9 + 6 + 13.68

= 28.68

Thus, The value of the perimeter and area of the triangle are,

20.52 cm² and 28.68 cm

Answers

Answer:

23/133

Step-by-step explanation:

If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.

The total number of freshmen in the school is 23/133

The number of students in the small school is 133

23 out of the 133 students are freshmen

Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133

Fraction of freshmen is 23/133

LORAN is a long range hyperbolic navigation system. Suppose two LORAN transmitters are located at the coordinates (−60,0) and (60,0), where unit distance on the coordinate plane is measured in miles A receiver is located somewhere in the first quadrant. The receiver computes that the difference in the distances from the receiver to these transmitters is 100 miles.

What is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola?

Answers

LORAN follows an hyperbolic path.

The equation of the hyperbola is: [tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]

The coordinates are given as:

[tex]\mathbf{(x,y) = (-60,0)\ (60,0)}[/tex]

The center of the hyperbola is

[tex]\mathbf{(h,k) = (0,0)}[/tex]

The distance from the center to the focal points is given as:

[tex]\mathbf{c = 60}[/tex]

Square both sides

[tex]\mathbf{c^2 = 3600}[/tex]

The distance from the receiver to the transmitters is given as:

[tex]\mathbf{2a = 100}[/tex]

Divide both sides by 2

[tex]\mathbf{a = 50}[/tex]

Square both sides

[tex]\mathbf{a^2 = 2500}[/tex]

We have:

[tex]\mathbf{b^2 = c^2 - a^2}[/tex]

This gives

[tex]\mathbf{b^2 = 3600 - 2500}[/tex]

[tex]\mathbf{b^2 = 1100}[/tex]

The equation of an hyperbola is:

[tex]\mathbf{\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1}[/tex]

So, we have:

[tex]\mathbf{\frac{(x - 0)^2}{2500} + \frac{(y - 0)^2}{1100} = 1}[/tex]

[tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]

Hence, the equation of the hyperbola is: [tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]
