Answer:

The final sale price is $30,000.

Step-by-step explanation:

50% of $20,000 is $10,000.

$20,000+$10,000=$30,000.

Final answer:

To find the final sale price with a 50% markup on the original $20,000 price, add $10,000 (which is 50% of $20,000) to get a final sale price of $30,000.

Explanation:

To calculate the final sale price of a car after a 50% markup, we take the original purchase price of the car and add half of that price to it. If the car dealership buys a car for $20,000, a 50% markup would be half of $20,000, which is $10,000. So, the final sale price would be:

$20,000 (original price) + $10,000 (50% of $20,000) = $30,000.

Hence, the car dealership would sell the car for $30,000 after a 50% markup.

Answer:

There are 15 orange picks when we have 25 picks total

Step-by-step explanation:

orange: green    : total

3               2            5

We found the total by adding the orange and the green

We have 25 total picks

25/5 = 5

We need to multiply by 5 on everything to get to 25 picks

orange: green    : total

3 *5           2*5        5*5

15                10           25

There are 15 orange picks when we have 25 picks total

Answer: There are 15 orange picks

Step-by-step explanation:

First we know that the ratio for Orange to Green is 3:2 so that for each five picks 3 of them are orange and 2 of them are green 25/5 is 5 so that means there are 5 five picks and as established every five picks is 3 orange picks we can say 3*5=15

Answer:

Graph B has 1 real root

Graph A has a negative discriminant

Graph C has  an equation with a=1, b=4 , c=-2

Step-by-step explanation:

If we look at the graph, Graph A never crosses the x axis, so it does not have any real roots.

Graph B touches the x axis, but does not cross so it has 1 real root

Graph C crosses the x axis 2 times, so it has 2 real roots.

We know from the discriminant b^2-4ac

If the discriminant >0 it has 2 real roots, so Graph C has a positive discriminant

If the discriminant =0 it has 1 real root, so Graph B has a zero discriminant

If the discriminant <0 it has 0 real roots, so Graph A has a negative discriminant

If we have a=1, b=4 , c=-2

b^2-4ac = 4^2-4(1)(-2) = 16+8  = 24  >0  This must be Graph C

Problem 7) Decay

Problem 8) Growth

Problem 9) Growth

==========================================

Explanation:

The base of the exponent will tell us if we have growth or decay.

In general, we have an equation in the form y = a*b^x with b as the base of the exponent

We can have b = 1+r where r is the growth rate. If r is negative, then that growth is really decay (or the amount is shrinking)

For problem 7, the base is 0.04 so 1+r = 0.04 leads to r = -0.96; so the amount is shrinking or decaying by 96% each time x increases by 1.

In problem 8, we have growth because 1.4 = 1+0.40 = 1+r so r = 0.40 = 40% growth

Finally, in problem 9, we can break up the base 6 into 6 = 1+5.0 = 1+r meaning r = 5.0 = 500% growth

Answer:

y = 1/4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b

m is the slope and b is the y intercept

but we do not know the slope y know the x intercept

(4,0 )

and  the y intercept

( 0,-1)

We can calculate the slope  using these points

m = (y2-y1)/ (x2-x1)

   = (-1-0)/(0-4)

    = -1/-4

    = 1/4

Now we can put the slope = 1/4 and the y intercept =-1 into the formula

y = 1/4x-1

y=1/4x-1 I think is the answer to that question

Answer: Number 3- The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.

Step-by-step explanation:

The following data show the prices of different types of outfits at a store:

$2, $2, $28, $26, $25, $27, $25, $27, $26, $28, $30

Which statement is correct about the box plot for the above data? (1 point)

1. The box plot will have its right tail longer than the left tail because a few exceptionally low prices make the distribution skewed to the right.

2. The box plot will have its right tail longer than the left tail because a few exceptionally low prices make the distribution skewed to the left.

3. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.

4. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the right.

The two $2 at the beginning of the data are outliers. They are exceptionally lower than all the other numbers, meaning they will be alone at the beginning of the data. That is the left! Now, it is number 3 and not 4 because it makes the data skewed to the left because of the low prices, not right. The two $2 hang off to the left. Which means the answer is number 3!

3. The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.

Answer:

The y-intercept in coordinate form is (0, 4.5) and represents the taxi pick-up fee.  The equation is y=1.5x + 4.5.

Step-by-step explanation:

This question is asking for the slope and y-intercept of a linear equation.  A linear equation makes a straight line based on a constant rate of change.  For this problem, the cost per mile is the slope, while the independent variable 'x' is the number of miles and the dependent variable 'y' is the total cost.  In order to first find slope, you need to use the two points given (7, 15) and (10, 19.5) to set up a change in y / change in x, or (19.5-15)/(10-7) or 4.5/3 which is 1.5.  So the slope, or cost per mile is $1.50.  To find the y-intercept (b), or the cost of the pick-up fee, simply fill in your equation y=1.5x + b with your other variables and solve for 'b'.  So, 15 = (1.5 x7) + b.  or 15 = 10.5 +b, subtract 10.5 from both sides of the equation to get b=4.5.  

You're really close. lol.

the slope of the line isn't negative though.

when the line is moving up to the right, it's positive.

the y-intercept is also positive. the y-intercept is where the line intercepts with the y-axis. if you look at the graph, you'll see that the line intercepts with the y-axis at +8 instead of -8

The answer is:

C. y = 1/4x + 8

Answer:

No that's wrong it is the third one.

Step-by-step explanation:

The line is on a positive slope so it has to be a positive x-value. Also, the y intersect is at positive 8.

Answer:

w = 31

Step-by-step explanation:

To find the value of w:

 We know that the three angles in a triangle add to 180 degrees

w + w + (4w-6) =180

Add like terms

6w-6 = 180

Add 6 to each side

6w -6+6 =180+6

6w = 186

Divide each side by 6

6w/6 = 186/6

w = 31

B) 24/26

Step-by-step explanation:

The ratio of sine is opposite/hypotenuse.  This means the side opposite angle D, EF, has length 24 and the hypotenuse, DE, has length 26.

The ratio of cosine is adjacent/hypotenuse.  For cos E, we want the side adjacent to E (EF) and the hypotenuse (DE).  Using these, we have the ratio 24/26.

In DEF, sin D= 24/26  , then cos E = 24/ 26. Option B) 24/26 is correct.

Trigonometric ratios are defined as the sides and angles of a right-angled triangle are deal with in Trigonometry.

We have,

In DEF sin D= 24/26

Using Pythagoras Theorem,

[tex]P^2 + B^2 = H^2\\\\EF^2 +FD^2 = EF^2\\\\24^2 + FD^2 = 26^2\\\\FD^2 = 676 - 576\\\\FD^2 = 100\\\\FD = 10[/tex]

But, cos E = EF / ED

cos E = 24/ 26

Hence, we can say that In DEF, sin D= 24/26  , then cos E = 24/ 26.

Since y=7 when x=2, we can from here simplify and see that y=3.5 when x=1. If y=21, then we multiply 7 by 3 which is 21, and since we must keep a proportion, we must multiply 2 by 3 and get 6 as the answer.

In an arithmetic sequence, the difference between one term and the next is constant.

The 65th term of the arithmetic sequence is -734

Given the following arithmetic sequence:

-30, -41, -52 The standard formula for the nth term of an arithmetic sequence is given as

a(n) = a + (n - 1)d

Where a = first term

            n = number of term

             d = common difference

Let find the common difference

Common difference = second term - first termCommon difference

= -41 - (-30)

Common difference =  -41 + 30

Common difference = -11

Common difference = -52 - (-41)

Common difference = -52 + 41

Common difference = -11

Hence, the common difference

= -11

let:

a = -30n

= 65d = -11a(65)

= -30 + (65 - 1) * -11a(65)

= -30 + (64)*-11a(65)

= -30 + (-704)a(65)

= -30 - 704a(65)

= -734

Hence, the 65th term of the arithmetic sequence is -734

Step-by-step explanation:

does 2 by 7 = 11 by 37

11/2 = 5.5

7 x 5.5 = 38.5

No, these two figures are not scaled versions of each other.  11 is 5.5 times larger than 2 which means to be a scaled version we would multiply 7 by 5.5.  

7 x 5.5 = 38.5

In order to be a scaled version the second recangle would need to be 11 by 38.5

The second rectangle is a scaled version of the first rectangle with a scale factor of 1/5.5.

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.

To determine if two figures are scaled versions of each other, we need to compare their corresponding side lengths.

The ratio of the corresponding side lengths is the same for both figures, then they have scaled versions of each other.

As per the question, the first rectangle has sides with lengths 2 and 7 units, while the second rectangle has sides with lengths 11 and 37 units.

So, the ratio of the corresponding side lengths is 2/11 = 7/37.

The scale factor is the ratio of the corresponding side lengths.

In this case, the scale factor is 2/11 = 1/5.5.

Therefore, the second rectangle is a scaled version of the first rectangle with a scale factor of 1/5.5.

20pounds/day * 14days * 20horses

The correct expression to determine the total hay consumption by 20 horses in two weeks is 20 × (20 × 14), which equals 5,600 pounds. Thus, the correct answer to the student's question is option (B).

The question from the student involves finding the total amount of hay consumed by a group of twenty horses over a period of two weeks. This problem can be solved with a straightforward multiplication.

Since one horse eats 20 pounds of hay each day, we can calculate the total hay consumption for one horse over two weeks (which is 14 days) by multiplying the daily consumption by 14:

To find out how much hay 20 horses eat in two weeks, we multiply the amount that one horse would eat in two weeks by 20:

Hence, the correct expression and evaluation to determine the total amount of hay consumed by 20 horses in two weeks is:

Answer:

3 would be the original number :D

Step-by-step explanation:

3x5 = 15.  15 - 3 = 12.

To solve this problem, we need to use algebra to find the value of the unknown number.

To solve this problem, we can use algebra. Let's let the number be represented by the variable x. According to the problem, 5 times x minus 3 equals 12. We can write this as the equation 5x - 3 = 12. To find the value of x, we need to isolate it on one side of the equation. Adding 3 to both sides, we have 5x = 15. Then, dividing both sides by 5, we get x = 3.

This is a basic algebraic problem. To solve it, we have to set up an equation. Let's denote the unknown number as x. According to the problem, the number (x) is multiplied by 5, and then 3 is subtracted from the result. This operation reaches the final result which is 12. Written in form of equation, it is: 5x - 3 = 12.

To solve for x, you need to isolate it on one side of the equation. First, add 3 to both sides of the equation to get rid of the -3 on the left side: 5x = 12 + 3, or 5x = 15. Then, you divide both sides by 5: x = 15 / 5. So, the value of x is 3.
