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 car so she reduced asking price by 20%. If she sells the car at the reduced price, she will have a profit or a loss or will she break even?

10.1 #17

Answers

Answer:

She will have a loss of $ 120

Step-by-step explanation:

Purchase price of car = $ 3000

20% of 3000 = [tex]\frac{20}{100}*3000[/tex]

                     = 20 * 30

                    = $ 600

Selling price = 3000 + 600 = $ 3600

Reduction price = 20%  of 3600

                          [tex]\frac{20}{100}*3600[/tex]

                       = 20  * 36

                       = $ 720

Current selling price after reduction = 3600 - 720

                                                            = $ 2880

Loss = 3000 - 2880

        = $ 120

She will break even
3000x20%=600. Which is above her purchase price total 3600 and she couldn’t sell.
She reduced the asking price(3600) by 20%
Which would -600. Now she’s asking 3000 what she paid.

XLiV represents 64 true ya false​

Answers

Answer:

False

Step-by-step explanation:

Given

[tex]XLIV = 64[/tex]

Required

True or False

The above numeral can be split as follows:

[tex]XLIV = XL + IV[/tex]

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

[tex]XL = -10 + 50[/tex]

[tex]XL = 40[/tex]

In Roman numerals;

[tex]IV = 4[/tex]

Substitute 40 for XL and 4 for IV.

[tex]XLIV = 40 + 4[/tex]

[tex]XLIV = 44[/tex]

Hence;

[tex]XLIV = 64[/tex] is false

Find the specified value.
(2x +5)
a. Using the figure to the right, find the value of x.

b. Using the figure to the right find the value of y.

Answers

Answer:

a. The value of x is [tex]38^{o}[/tex].

b. The value of y is [tex]25^{o}[/tex].

Step-by-step explanation:

a. Applying the vertically opposite principle,

(2x + 5) = (3x - 33)

2x + 5 = 3x - 33

33 + 5 = 3x - 2x

38 = x

⇒ x = [tex]38^{o}[/tex]

b. Sum of angles on a straight line = [tex]180^{o}[/tex]

So that,

(4y - 1) + (3x - 33) = [tex]180^{o}[/tex]

But,

( 3x - 33) = (3x38 - 33)

               = 114 - 33

               = [tex]81^{o}[/tex]

(4y - 1) + [tex]81^{o}[/tex] = [tex]180^{o}[/tex]

4y - 1 = [tex]180^{o}[/tex] - [tex]81^{o}[/tex]

         = [tex]99^{o}[/tex]

4y = [tex]99^{o}[/tex] + 1

    = [tex]100^{o}[/tex]

y = [tex]\frac{100}{4}[/tex]

  = [tex]25^{o}[/tex]

y = [tex]25^{o}[/tex]

The value of x is [tex]38^{o}[/tex], and y is [tex]25^{o}[/tex].

11.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

you have to use this equation to solve it [r = (1/t)(A/P - 1)] and basically just plug the numbers in to get 11.5. (you could also use one of those online calculators)

r = (1/2)((4920/4000) - 1) = 0.115

The areas of two similar triangles are 18cm^2 and 8cm^2. One of the sides of the first triangle is 4.5cm. What is the length of the corresponding side of the other triangle? Please answer ASAP!!! Thank you!!!

Answers

Answer:

3 cm

Step-by-step explanation:

The area is the product of two dimensions, therefore the scale factor is:

A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5

The length of the corresponding side will be:

a/a' = ra' = a/ra' = 4.5 / 1.5 a' = 3 cm

Answers

Answer:

Part A. The girls have 7/8 pizza all together.

Part B. Samantha drank 5/10 or 1/2 water that day.

Step-by-step explanation:

Part A. The answer is 7/8 because 2/4 is the same thing as 4/8.

2/4 = 4/8

4/8 + 3/8 = 7/8.

So, for the first question the answer is 7/8.

Part B. The answer is 5/10 because 1/5 = 2/10

1/5 = 2/10

2/10 + 3/10 = 5/10

Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school

Answers

Answer:

Her usual time from home to school is 30 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Here, we want to calculate the normal time she spent going from home to school

Let the normal time be x minutes

And the normal speed be t m/min

Today, she increased her speed by 20%

Her speed today will be t + 20/100 * t =

1.2t m/min

Her distance from how to school normally is

xt meters

Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier

What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes

So, the time spent on her increased speed journey is;

(x-5) minutes

At any point in time, the distance will be equal;

Thus, mathematically;

xt = 1.2t(x-5)

xt = 1.2xt - 6t

6t = 1.2xt-xt

6t = 0.2xt

t cancels out

0.2x = 6

x = 6/0.2

x = 30 minutes

Answer: Choice A) If Amber and Jorge each sell 5 trees in one week, they will earn the same amount

The amount they earn is $200 each.

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

Explanation:

Let's form the equation for the amount Amber earns.

She starts off at $150, and then we add on 10x dollars. The 10x is because she earns 10 dollars per tree, and we have x be the number of trees sold.

Overall we can say her equation is y = 150+10x

This is the same as y = 10x+150

----------

Since Jorge's equation is y = 25x + 75, we can apply substitution to solve for x

y = 10x+150

25x+75 = 10x+150 .... replace y with 25x+75

25x+75-10x = 150 ... subtract 10x from both sides

15x+75 = 150

15x = 150-75 ... subtract 75 from both sides

15x = 75

x = 75/15 .... divide both sides by 15

x = 5

If they sell 5 trees per week, then Amber and Jorge earns the same amount of money.

That amount earned is

Amber: y = 10x+150 = 10*5+150 = 50+150 = 200 dollars

Jorge: y = 25x+75 = 25*5+75 = 125+75 = 200 dollars

Both earn $200 per week from selling 5 trees for that week. This helps confirm we have the right answer.

The time a student sleeps per night has a distribution with mean 6.06 hours and a standard deviation of 0.55 hours. Find the probability that average sleeping time for a randomly selected sample of 35 students is more than 6.15 hours per night.

Answers

Answer:

The probability is 0.16602

Step-by-step explanation:

We start by calculating the z-score

We have this mathematically as;

z-score = (x-mean)/SD/√n

From the question,

we have x = 6.15

mean = 6.06 hours

standard deviation = 0.55 hours

n = 35

Substituting these values, we have

z-score = (6.15-6.06)/0.55/√35

z-score = 0.09/0.55/5.92

z-score = 0.97

So the probability we want to calculate is:

P ( z > 0.97)

we make use of the standard normal distribution table here

The value is; 0.16602

Why isn’t a good idea to study in bed?

Answer: Working or doing homework in bed will reduce one's focus because most people tend to associate their beds with comfort and sleep. Doing such activities in bed can lead to a deviation of the brain to become more lazy and possibly fall asleep.

Disadvantages of studying in bed includes issues related to posture and concentration. Hence, studying in bed often ;

Induces sleep and weariness

Inappropriate posture required for studying and assimilation.

A bed is primarily meant for sleeping while desks and chairs are made for studying. The difference in the build is due to the purpose of nature of each activity. Studying in an environment meant for sleeping would most likely induce sleep.

Similarly the structure or design of a bed isn't appropriate for studying and may likely affect the rate of assimilation.
