Solution: We are given:
Predicted Sales by Sameera [tex]=38[/tex]
Actual Sales by Sameera [tex]=28[/tex]
Now to find the Percent error, we have to use the below formula:
[tex]Percent-Error= \frac{|Predicted-value - Actual-value|}{Actual-value} \times 100 \%[/tex]
[tex]=\frac{|38-28|}{28} \times 100 \%[/tex]
[tex]=\frac{10}{28}\times 100 \%[/tex]
[tex]=35.71 \%[/tex]
Therefore, the percent error is [tex]35.71 \%[/tex]

What is the difference ? X/x^2-2x-15-4/x^2+2x-35
x / x² - 2x - 15 - 4 / x² + 2x - 35
FIND THE FACTOR OF EACH DENOMINATOR
= x / (x-5)(x+3)
- 4 / (x-5) (x+7)
FIND THE LCD AND MULTIPLY EACH TERM TO ARRIVE AT THE SAME DENOMINATOR.
= x / (x-5)(x+3) *
(x+7) / (x+7) - 4 / (x-5) (x+7) * (x+3)/(x+3)
PERFORM SUBTRACTION
= x2 + 7x / (x-5) (x+3) (x+7) - (4x + 12) / (x-5) (x+7) (x+3)
= x2 + 7x – 4x – 12 / (x-5) (x+3) (x+7)
this would be your answer = x² + 3x – 12 / (x-5) (x+3) (x+7)

She would put 1000.00 a year into an account starting on the babys 1st birthday
Hello Azzizigilchrist.
The equation of this question would be $1000x
x stands for the amount of years it has been
So if it has been 4 years, 1000 * 4 equals 4000

An animal shelter currently only has 30 dogs and 20 Cats. What is the ratio cats to animals?
Answer: 3:2
Step-by-step explanation:
Given : An animal shelter currently only has 30 dogs and 20 Cats.
i.e. Number of dogs = 30
Number of cats = 20
Then, the ratio of cats to animals is given by :-
[tex]\dfrac{\text{Number of cats}}{\text{Number of animals}}\\\\=\dfrac{30}{20}\\\\=\dfrac{3}{2} \ \ \text{[By dividing 10 in the numerator and denominator]}[/tex]
Therefore, the ratio of cats to animals = 3:2

An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint. What is the scale for this blueprint?
Answer:
The scale is : 1 in : 2.5 ft
Step-by-step explanation:
An architect notices that the scale on a blueprint he is using has been torn off.
However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint.
Let the scale be x
[tex]\frac{5}{12.5} =\frac{1}{x}[/tex]
So, scale = [tex]x=\frac{12.5}{5}[/tex] = 2.5
So, the answer is : 1 in : 2.5 ft
Answer:
The scale is : 1 in : 2.5 ft

What is the length of the hypotenuse of the triangle? 26 ft 34 ft 68 ft 74 ft
Answer: 26 ft.
Step-by-step explanation:
In the given picture, there is a right triangle.
The legs of the right triangles are 10 ft and 24 ft.
To find the length of hypotenuse, we use Pythagoras theorem, we get
[tex]H^2=10^2+24^2\\\\\Rightarrow\ H^2=100+576\\\\\Rightarrow\ H^2=676\\\\\Rightarrow\ H=\sqrt{676}\\\\\Rightarrow\ H=26\ ft[/tex]
Hence, the length of the hypotenuse = 26 ft.
Pythagoras theorem says that the square of the hypotenuseis equal to the sum of the squares of the other two sides.convert 4 3/4 to an improper fraction:

It is safe to assume the goal is to solve for 'r'. To do so we need to isolate 'r'.
[tex]-3r = 1/2(32-8r)\\\\-3r = 16-4r\\\\r = 16[/tex]
An item that is normally sells for $130 is marked down 30%. What is the sale price
To find the sale price of an item that is normally $130 with a 30% markdown, calculate the discount amount ($39) and subtract it from the original price to get a sale price of $91.
The question asks to calculate the sale price of an item after a 30% markdown. To determine the sale price, you have to first calculate the discount amount and then subtract it from the original price of the item. Here's how you do it:
Find the discount amount: original price x discount rate.Subtract the discount amount from the original price to get the sale price.For an item that is normally sold for $130 and is marked down 30%, the sale price can be calculated as follows:
Discount amount: $130 x 0.30 = $39.Sale price: $130 - $39 = $91.Find the common difference in the outputs to help find the missing outputs in the table
ɑ 5 6 7 8 9
b 3.8 4.6 5.6 ? ?
we have been given table containing 6 points.
let the numbers at question mark (?) are x and y respectivelly so we can rewrite the table as:
[tex]\left[\begin{array}{cccccc}a&5&6&7&8&9\\b&3.8&4.6&5.4&x&y\end{array}\right][/tex]
In the first row we see that numbers increase by 1 so that clearly means a=4.
Now we need to find the common difference in the outputs to help find the missing outputs in the table.
4.6-3.8=0.8
5.4-4.6=0.8
we are getting common difference of 0.8 so that means missing values can be found by adding or subtracting 0.8 as per their position.
b=3.8-0.8=3
x=5.4+0.8=6.2
y=6.2+0.8=7
Hence the final answer is given by table:
[tex]\left[\begin{array}{cccccc}4&5&6&7&8&9\\3&3.8&4.6&5.4&6.2&7\end{array}\right][/tex]

Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show. After paying the agent, Daniel takes home $120. Use the diagram to answer the following questions.
Daniel’s agent made .
Daniel and the agent made a total of from the show.
Answer:
Daniels agent made $40.
Daniel and the agent made a total of $160 from the show.
Step-by-step explanation:
Given:
Let the total amount made from the show = x
Daniel's agent made = 25% of x
Daniel made = $120
From the question, we know that the total amount is the sume of what daniel and the agent took.
So,
x = 120 + 25% of x
x-0.25x = 120
0.75x = 120
x = 160.
Hence the total amount made from the show is $120.
Daniel's agent made = 25 % of 160
= 0.25*160
= 40
Hence, Daniel's agent made $40 from the show.
Answer:
40
160

write and solve an equation to find the missing value:
Solve for b2: A=1/2(b1+b2)h
[tex]b_{2}[/tex] = [tex]\frac{2A}{h}[/tex] - [tex]b_{1}[/tex]
multiply both sides by 2 to eliminate the fraction
([tex]b_{1}[/tex] + [tex]b_{2}[/tex] )h = 2A
divide both sides by h
[tex]b_{1}[/tex] + [tex]b_{2}[/tex] = [tex]\frac{2A}{h}[/tex]
subtract [tex]b_{1}[/tex] from both sides
[tex]b_{2}[/tex] = [tex]\frac{2A}{h}[/tex] - [tex]b_{1}[/tex]

The transformation of triangle abc is an example of what
Final answer:
The transformation of triangle ABC is an example of a linear transformation that preserves lines and parallelism.
Explanation:
The transformation of triangle ABC is an example of a linear transformation.
A linear transformation is a transformation that preserves lines and parallelism. It transforms lines into lines and takes parallel lines to parallel lines.
For example, if triangle ABC is transformed into triangle A'B'C', the corresponding sides of the triangles will be parallel. Additionally, any lines within the triangle will remain lines after the transformation.
