Car S was built this year and has an original price of $22,860.
Based on this information, which statement is true?

Question 10 options:

The customer would pay $24,073 for Car R.


The customer would pay $19,324 for Car S.


The customer would pay $23,107 for Car R.


The customer would pay $21,824 for Car S.

Answers

Answer:

3.55,11.25,48.20,49.413,42.184

Step-by-step explanation:

$3,500 + 0.05% = $3.55

$1,250 + 0.010% = $11.25

$25,340 + $22,860 = $ 48.20

$25,340 + $ 24,073 = $ 49.413

$22,860 + $ 19,324 = $42.184

Plot G(8,-6) , H(2,-6) , J(7,4) , and K(7,10) in a coordinate plane. Are GH and JK congruent?

Answers

Answer:

Yes GH ≅JK

Step-by-step explanation:

The line GH and JK are congruent because they measures are equal.

JK line is vertical so the x-coordinate is constant and the difference in y is 10-4 = 6 and

GH line is horizontal so the y-coordinate is constant and the difference in x is 8-2 = 6

Find the inverse of f(x)=5x-4.
The inverse of f is g(x)= ?

Answers

If g(x) is the inverse of f(x), then by definition of inverse function,

f(g(x)) = g(f(x)) = x

Given that f(x) = 5x - 4, we have

f(g(x)) = 5 g(x) - 4 = x

Solve for g(x) :

5 g(x) - 4 = x

5 g(x) = x + 4

Use vertical angles and supplementary angles to find all the six pack of angles right in the middle of the diagram. 40°, 50°, 90°, 40°, 50° 90° And the use the idea that a triangle's three angles must add up to 180°.

Elaine drives her car 70 miles and has an average of a certain speed. If the average speed had been 3mph more, she could have traveled 77 miles in the same length of time. What was her average speed

Answers

Answer:

30 miles/hr

Step-by-step explanation:

d / r  = time     distance divided by rate = time

70 / r   = time     and    77/(r+3 ) = time       r = her original average speed

 'time' is the same for both so we can equate the equations

70/r = 77/(r+3)     cross multiply

70r + 210 = 77r

7r = 210

r = 30 m/hr

The graph of a linear equation has a slope of 4 and an x-intercept at (2, 0). What is the y-intercept of the graph?

Answers

Answer:

y-intercept = -8

Slope-intercept form of a linear equation: y = mx + b

(where m is the slope and b is the y-intercept)

Given:

slope (m) = 4point (x₁, y₁) = (2, 0)

Substituting the given values into the slope-point form of a linear equation:

Answers

The amount you would pay altogether if you borrow $500 for  5 years at

an annual interest rate of 7% is $945.

How much would you pay altogether?

The amount you would pay altogether is the sum of the amount borrowed and the interest.

Total value of the debt = interest + amount borrowed

Interest = $700 x 7% x 5 = $245

Total value of the debt = $245 + $700 = $945

Assume that 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A. What is the approximate probability that someone that gets an A actually studied for the Psychology test

Answers

The probability that someone that gets an A actually studied for the Psychology test is 0.15 or 15% if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Let A = the students get an A

Let B = the student's studied for the psychology test

We know that probability:

P(B) = 60% = 0.60  and

P(A/B) = 25% = 0.25

We know that:

[tex]\rm P(A/B) = \frac{P(A\cap B)}{P(B)} = 0.25[/tex]

Now the probability that someone that gets an A actually studied for the Psychology test:

P(A∩B) = P(B) ×0.25

P(A∩B)  = 0.60×0.25

P(A∩B)  = 0.15

Thus, the probability that someone that gets an A actually studied for the Psychology test is 0.15 if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.

Volume is the space occuppied by an object. In this question we must determine the volumes of pyramids of circular base and polygonal base (V). All the formulas needed are described below:

Volume of the pyramid

V = (π/3) · B · h     (1)

Base of the pyramid - Circle

B = (π/4) · R²     (2)

Base of the pyramid - Regular polygon

B = (n · L²)/(4 · tan 0.5α)     (3)

Base of the pyramid - Right triangle

B = (1/2) · b · z     (4)

Base of the pyramid - Rectangle

B = b · z

Where:

R - Radiusn - Number of sides of the polygon.l - Side lengthα - Internal angle, in degree.h - Height of the pyramidb - Base of the right triangle/rectangle.z - Length of the right triangle/rectangle.

Now we proceed to solve each pyramid:

1) Square, n = 4, α = 90°, L = 14 cm, h = 22 cm

B = 196 cm², V = 1437.333 cm³

2) Circle, R = 3 km, h = 8 km

B ≈ 28.274 km², V = 75,398 km³

3) Right triangle, b = 12 ft, z = 3.7 ft, h = 8 ft

B = 22.2 ft², V = 59.2 ft³

4) Rectangle, b = 23 yd, z = 9 yd, h = 5.7 yd

B = 207 yd², V = 393.3 yd³

5) Circle, R = 9.5 m, h = 12 m

B ≈ 283.529 m², V = 1134.116 m³

6) Regular pentagon, B = 110 mm², h = 11 mm

V = 403.333 mm³

7) Square,n = 4, α = 90°, L = 13 in, h = 7.2 in

B = 169 in², V = 405.6 in³

8) Regular triangle, n = 3, α = 120°, L = 16 ft, h = 24 ft

B ≈ 110.851 ft², V = 886.808 ft³

x is an integer.
The Lowest Common Multiple (LCM) of x and 12 is 120
The Highest Common Factor (HCF) of x and 12 is 4
Work out the value of x

Answers

Since 120 = 12 • 10 and LCM(x, 12) = 120, these suggest x is some multiple of 10.

HCF(x, 12) = 4 tells us that x is a multiple of 4.

If x is a both a multiple of 4 and 10, then the smallest x that fits both conditions is 4 • 10 = 40. (-40 also satisfies the criteria.)

The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.

What do we mean by Lowest Common Multiple (LCM) and Highest Common Factor (HCF)?

The Lowest Common Multiple (LCM) of the numbers is the smallest common multiple of the given numbers.

The Highest Common Factor (HCF) of the numbers is the greatest factor of the given numbers.

In the case of two numbers, the product of LCM and HCF is equal to the product of the numbers.

How do we solve the given question?

We are given two numbers, x and 12.

Their LCM and HCF are 120 and 4 respectively.

We are asked to find the number x.

For two numbers, we know that the product of two numbers is equal to the product of their HCF and LCM.

∴ x*12 = 120*4

or, 12x = 480

or, x = 480/12

or, x = 40.

∴ The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.
