CJ earned a score of 75% on his math quiz. Each question on the quiz was worth 1 point, and CJ got 18 questions correct. How many questions were on the quiz? There were questions on the quiz
Answer:
24 questions
Step-by-step explanation:
Given
[tex]Score = 75\%[/tex]
[tex]Correct\ Questions = 18[/tex]
Required
Determine the number of question
Represent this with n.
Since each question has 1 point each, then
[tex]Score * Number\ of\ questions = Correct\ Questions[/tex]
Substitute values for Score, Number of Questions and Correct Questions
[tex]75\% * n = 18[/tex]
Make n the subject.
[tex]n = \frac{18}{75\%}[/tex]
Convert percent to decimals
[tex]n = \frac{18}{.75}[/tex]
[tex]n = 24[/tex]
Hence, there are 24 questions in total

Gretta has 40 raffle tickets to sell. She is required to sell at least 15 tickets. She sells the raffle tickets for $10 each. The amount of money Gretta makes from selling x raffle tickets is represented by a function. f(x)=10x What is the practical range of the function?
Answer:
Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.
Step-by-step explanation:
We have been given the information that gretta is selling x raffle ticket by a function
f(x)=10 x
Range is the values that y takes in a particular function
Here, we will get any value which is multiple of 10 since we have a function 10 times of something whatever value we put for x we will get multiple of 10.
Hence, Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.
This isn't something specific I need to know for school, I'm just curious. I know the most commonly used variables are x, y, and z. But what if you have more then three variables, what are the next letters you are supposed to use?
Answer:
Any letter you want
Step-by-step explanation:
The letters used for variables don't matter. What matters is what the variables represent: their numerical value. Variables are just to help identify what needs solving. Other common variables are a, b, and c which are found frequently in trigonometry. To answer your question, there are no "next letters." You can use any letter you'd like as a variable because it holds the same numerical value. Basically, the whole alphabet is at your disposal.

Step-by-step explanation:
Determine if the following figures are similar. Explain why or why not.
Answer:
They are not the same
Step-by-step explanation:
4m x 8m = 32m
10m x 20m = 200m
So...they are not similar
Only similarity is both of them are rectangles
Answer:
No, the ratios of the corresponding sides are not equal.
Step-by-step explanation:
Two or more figures are similar if they have exactly the same shape. Similar figures may be of different sizes. Similar figures have corresponding sides and corresponding angles. Corresponding sides have lengths that are proportional.
Challenge A large university accepts 50% of the students who apply. Of the students the
university accepts, 25% actually enroll. If 20,000 students apply, how many actually enroll?
students would actually enroll.
Answer:
Step-by-step explanation:
20,000 students 50% are accepted so that is 10,000 students of that 10,000 only 25% enroll which is 2,500.
Answer:
2,500 students
Step-by-step explanation:
50% of 20,000 is the amount of students that were accepted. That makes 10,000 students accepted. 25% of 10,000 is the amount enrolled. 25% is 1/4. So 1/4 of 10,000 is 2,500. So 2,500 students enrolled in that university.
The salary scale for an officer starts at $1,700,000 .A rise of $4000 is given at the end of each share . Find the total amount of money the officer will earn in 14 years
9514 1404 393
Answer:
$24,164,000
Step-by-step explanation:
The yearly salaries form an arithmetic sequence with a first term of 1700000 and a common difference of 4000.
The sum of n terms of an arithmetic sequence with first term a1 and common difference d is ...
Sn = (2a1 +d(n -1))(n/2)
For the given numbers, the sum of 14 years' salaries will be ...
S14 = (2·1,700,000 +4,000(14 -1))(14/2) = 24,164,000
The officer will earn $24,164,000 in a 14-year period.
Clearly, we can see that salary of the officer is in form of Arithmetic progession, where :
First term, a = $ 1,700,000Common difference = $ 4000Number of terms, n = 14And we have to find total salary i.e. [tex] \tt s_{n} = ?[/tex]
Now, we know that :
[tex] \large \underline{\boxed{\bf{S_n = \dfrac{n}{2} \Bigg(2a + (n-1) d\Bigg)}}}[/tex]
By substituting values :
[tex] \tt : \implies S_n = \dfrac{14}{2} \Bigg(2(1700000) + (14-1) (4000)\Bigg)[/tex]
[tex] \tt : \implies S_n = \cancel{\dfrac{14}{2}} \Bigg(2\times 1700000 + 13 \times 4000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \Bigg(3400000 + 52000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \Bigg(3452000\Bigg)[/tex]
[tex] \tt : \implies S_n = 7 \times 3452000[/tex]
[tex] \tt : \implies S_n = 24164000[/tex]
[tex] \large \underline{\boxed{\bf{S_n = \$ 24,164,000}}}[/tex]
Hence, the total amount of money the officer will earn in 14 years is $ 24,164,000.
find the value of x
Answer:
9x= 360 -180
x= 180/9
x= 20°
Answer:
x = 30
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, thus
sum = 180° × 3 = 540°
Sum the given angles and equate to 540, that is
x + 106 + 90 + 74 + 8x = 540, simplify
9x + 270 = 540 ( subtract 270 from both sides )
9x = 270 ( divide both sides by 9 )
x = 30
A girl scout troop makes $1100 in two weekends of selling cookies. If they continued at this rate, how much money would they make in their seven weekend selling season?
Answer:
$3850
Step-by-step explanation:
It is given that,
A girl scout troop makes $1100 in two weekends of selling cookies.
2 weekend = $1100
1 weekend = $550
For 7 weekend, we will multiply $550 by 7 as follows :
7 weekend = $550 × 7
= $3850
So, for 7 weekend she will need $3850.
Describe each of the following transformation that maps the figures described below. Be specific by naming lines of reflection, centers of rotation and degrees of rotation, distance and direction of translations, and centers of dilation with a scale factor. Determine if the transformation is a rigid transformation or a similarity transformation. Explain all reasoning.
Part A: Figure 1 →Figure 4
Part B: Figure 2 → Figure 5
Answer:
Part A: Figure 1 → Figure 4
Rigid Transformation
Equivalent to a reflection about the origin, or a rotation of 180° clockwise or anticlockwise about the origin which are types of rigid transformation
Part B: Figure 2 → Figure 5
Similarity transformation
Figure 5 is Figure 2 dilated by a scale factor of 1/2, which is a form of a similarity transformation
Step-by-step explanation:
Part A: Figure 1 → Figure 4
The coordinates of the vertices of the preimage are;
(5, 10), (2, 4), (9, 2)
The coordinates of the vertices of the image are;
(-9, -2), (-2, -4), (-5, -10)
Which is equivalent to a reflection about the origin, or a rotation of 180° clockwise or anticlockwise about the origin
Part B: Figure 2 → Figure 5
The coordinate points of figure 2 are;
(-9, 2), (-5, 10), and (-2, 4)
The coordinate points of figure 5 are;
(1, 2), (2.5, -1), and (4.5, 3)
The lengths of the sides of figure 2 are;
√((10 - 2)² + ((-5) - (-9))²) = 4·√5
√((10 - 4)² + ((-5) - (-2))²) = 3·√5
√((2 - 4)² + ((-9) - (-2))²) = √53
The lengths of the sides of figure 5 are;
√(((-1) - 2)² + (2.5 - 1)²) = (3·√5)/2
√((4.5 - 2.5)² + (3 - (-1))²) = 2·√5
√((4.5 - 1)² + (3 - 2)²) = (√53)/2
Therefore. Figure 5 is Figure 2 dilated by a scale factor of 1/2
Therefore, given that the sides of Figure 2 and Figure 5 are rotated by 180°
We have;
Figure 5 is obtained as follows;
1) The rotation of figure 2 by 180°, clockwise or anticlockwise about the origin to get;
(-9, 2), (-5, 10), and (-2, 4) → (9, -2), (5, -10), and (2, -4)
2) The image is translated left by 1 blocks and up by 6 blocks as follows;
(9, -2), (5, -10), and (2, -4) → (8, 4), (4, -4), and (1, 2)
3) The image is then dilated by a scale factor of 1/2 with a center of dilation of (1, 2) to get;
Preimage (8, 4), (4, -4), and (1, 2) → Image (1, 2), (2.5, -1), and (4.5, 3).

The length of a rectangle 2 less than 2 times the width. The perimeter is 116ft. Find
the length and width.
Answer: w = 20 l = 38
Step-by-step explanation:
l = 2w - 2 (based on given info)
p = 2l + 2w (formula for perimeter)
p = 116 (given)
116 = 2l + 2w
116 = 2(2w-2) + 2w (substitute in l)
116 =‘ 4w-4 + 2w
116 = 6w-4
w=20
l=2(20) - 2 = 38

Answer:
X = 12.12
Step-by-step explanation:
Use the Pythagorean Theorem for this question.
[tex]a^2 + b^2 = c^2[/tex]
7 is one of the legs while 14 is the hypotenuse. So we set up the equation like this:
[tex]a^2 + 7^2 = 14^2[/tex]
Square 7 and 14:
[tex]a^2 + 49 = 196[/tex]
Minus 49 from both sides:
[tex](a^2 + 49) - 49 = (196) - 49[/tex]
[tex]a^2 = 147[/tex]
Square root both sides:
[tex]\sqrt{a^2} = \sqrt{147}[/tex]
[tex]a = 12.12[/tex]
Therefore x is equal to 12.12

Jonas was visiting Garner State Park. At the entrance, he saw a map of the park. The legend stated that 1.5 inches on the map represent 2.5 feet in the park. On the map, how many inches would represent 6 actual feet is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
On the map,
1.5 inches = 2.5 feet
1 feet = 1.5 / 2.5 inches
1 feet = 0.6 inches
Multiply both sides by 6.
6 feet = 3.6 inches
Thus, the required scale in inches for the 6 actual feet is 3.6 inches.
