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
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
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.
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
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
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.

XLiV represents 64 true ya false
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

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!!!
Answer:
3 cmStep-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 = 1.5The length of the corresponding side will be:
a/a' = ra' = a/ra' = 4.5 / 1.5 a' = 3 cmThere are 20 houses on Rainbow Street. 45% of the houses have holiday decorations in their yard. How many houses have decorations?
Answer:

Total 9 houses have decoration on Rainbow Street.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
Total number of houses on Rainbow Street = 20,
The percentage of the houses which have decorations = 45%
The number of houses which have decoration
= 20×(45/100)
