A woman purchased a used car for $3,000. She decided to sell the car for 20% above her purchase price. She could not sell the ca

irina1246 [14]

Answer:

She will have a loss of $ 120

Step-by-step explanation:

Purchase price of car = $ 3000

20% of 3000 = $\frac{20}{100}*3000$

= 20 * 30

= $ 600

Selling price = 3000 + 600 = $ 3600

Reduction price = 20% of 3600

$\frac{20}{100}*3600$

= 20 * 36

= $ 720

Current selling price after reduction = 3600 - 720

= $ 2880

Loss = 3000 - 2880

= $ 120

Answer:

12

Step-by-step explanation:

If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?

25 * 3 = 75

87 - 75 = 12

What is the measure of egf <br><br> A.40<br> B.55<br> C.65<br> D.80

Delicious77 [7]

Answer: C. 65

Step-by-step explanation:

Concept:

Here, we need to know the concept of an isosceles triangle.

An isosceles triangle is a triangle that has any two of its sides equal to each other. The corresponding angles of the equal sides are also equal.

If you are still confused, you may refer to the attachment below for a graphical explanation.

Solve:

Let x be m∠EGF

2x + 50 = 180 ⇒ Write the equation

2x + 50 - 50 = 180 - 50 ⇒ Subtract 50 on both sides

2x = 130 ⇒ Simplify

2x / 2 = 130 / 2 ⇒ Divide 2 on both sides

x = 65 ⇒ Simplify

Hope this helps!! :)

Given R = 10 and theta = 1.15 pi, find the Cartesian coordinates.

love history [14]

We have been given that $r=10$ and $\theta =1.15\pi$ . We are asked to find the Cartesian coordinates.

We know that $x=r\cdot \text{cos}(\theta)$ and $y=r\cdot \text{sin}(\theta)$ .

Let us convert polar coordinates to Cartesian coordinates using above formula.

$x=10\cdot \text{cos}(1.15\pi)$

$x=10\cdot (-0.891006524188)$

$x=-8.91006524188$

Round to nearest hundredths:

$x\approx -8.91$

$y=10\cdot \text{sin}(1.15\pi)$

$y=10\cdot (-0.45399049974)$

$y=-4.5399049974$

Round to nearest hundredths:

$y\approx -4.54$

Therefore, the Cartesian coordinates will be $(-8.91,-4.54)$ and option 'b' is the correct choice.

90 points!!! Algebra - Please check these

Korvikt [17]

First picture:

2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.

Angle 7 = 180 - 146 = 34

Answer is B.34

Second picture:

Angle 8 = 48

Angle 8 + angle 7 = 180

Angle 7 = 180 - 49 = 131

Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131

Angle 6 is a vertical angle to angle 8 so = 49

Angle 1 = angle 5 = 131

Angle 2 = angle 6 = 49

Angle 3 = angle 7 = 131

Angle 4 = angle 8 = 49
