Kaitlan sold 60% of her hockey card collection at the fall market sale. If she sold 240 cards, how many cards were in her collection?
Answer:
400
Step-by-step explanation:
Ok so if 60% of the total is 240 than create an expression:
60% of x=240
Now divide both sides by 3:
20% of x=80
Multiply both sides by 5 ( because 5 times 30 is 100):
100% of x=400
Thats the answer hope this helped! :)
400 cards were in her collection.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Total hockey cards sold= 240
So, Kaitlan sold 60% of her hockey card
let the total number of Hockey cards be x.
So, 60% of x= 240
60 x /100 = 240
x= 24000/ 60
x= 400
Hence, 400 cards were in her collection.

Given data
Cost of ride= $16
Amount paid= $20
Change= $4
Hence the percent of the tip is
=4/16*100
=0.25*100
=25%
Hence the percentage of the tip is 25%

Which points are on the graph of the function rule f(x) = 10 – 4x?
A. (18, –2), (10, 0), (2, 2)
B. (–2, 18), (0, 10), (2, 2)
C. (2, –18), (0, –10), (–2, –2)
D. (–18, 2), (–10, 0), (–2, –2)
Answer:
B. (–2, 18), (0, 10), (2, 2)
Step-by-step explanation:
Find the function by taking the integral of the derivative.
F ( x ) = 10 x − 2 x 2 + C
Given: f(x) = 10 - 4x
Just substitute in each points to see if they satisfy the equation.
Looking (c)
(-2,18) ----> 10 - 4(-2) = 10 + 8 = 18. (-2,18) is satisfied.
(0,10) ----> 10 - 4(0) = 10. (0,10) is satisfied.
(2,2) ----> 10 - 4(2) = 10 - 8 = 2. (2,2) is satisfied.
Therefore, (b) is the solution.

An artist used colored squares to put on the windows that measure 1/4 by 1/4 How many colored squares would fit in that area of the window?
The question is incomplete. The complete question is :
An artist used colored squares to put on the windows that measure 1/4 by 1/4 How many colored squares would fit in that area of the window? The window measures 3 1/2 feet by 2 3/4 feet?
Solution :
It is given that :
The measure of the window is = [tex]$3\frac{1}{2}$[/tex] feet by [tex]$2\frac{3}{4}$[/tex] feet
The measure of the colored square = [tex]$\frac{1}{4}$[/tex] feet by [tex]$\frac{1}{4}$[/tex] feet
So the area of the window is given as :
[tex]$=3\frac{1}{2} \times 2\frac{3}{4}$[/tex]
= 9.625 square feet
Similarly the area of the colored square [tex]$=\frac{1}{4} \times \frac{1}{4}$[/tex]
[tex]$=\frac{1}{16}$[/tex]
= 0.0625 square feet
Therefore, the total number of the colored squares required to fit the window is given by :
[tex]$=\frac{9.625}{0.0625}$[/tex]
= 154 colored squares

Answer:
2/5; 1/2; 2/3; 14/10; 2/6
Step-by-step explanation:
When finding equivalent fractions, multiply or divide both the numerator and denominator by the same number.
4/10 = 2/5 because 4÷2=2 and 10÷2=5
The same thing has been done to both the numerator and denominator (in this case they have both been divided by 2)
In the United States, voters who are neither Democrat nor Republican are called Independent. It is believed that 11% of voters are Independent. A survey asked 33 people to identify themselves as Democrat, Republican, or Independent. A. What is the probability that none of the people are Independent? Probability = B. What is the probability that fewer than 6 are Independent? Probability = C. What is the probability that more than 2 people are Independent? Probability =
Answer:
a) 0.0214 = 2.14% probability that none of the people are Independent.
b) 0.8516 = 85.16% probability that fewer than 6 are Independent.
c) 0.8914 = 89.14% probability that more than 2 people are Independent.
Step-by-step explanation:
For each people, there are only two possible outcomes. Either they are independent, or they are not. For each person asked, the probability of them being Independent voters is the same. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
It is believed that 11% of voters are Independent.
This means that [tex]p = 0.11[/tex]
A survey asked 33 people to identify themselves as Democrat, Republican, or Independent.
This means that [tex]n = 33[/tex]
A. What is the probability that none of the people are Independent?
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
0.0214 = 2.14% probability that none of the people are Independent.
B. What is the probability that fewer than 6 are Independent?
This is
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X = 2) = C_{33,2}.(0.11)^{2}.(0.89)^{31} = 0.1724[/tex]
[tex]P(X = 3) = C_{33,3}.(0.11)^{3}.(0.89)^{30} = 0.2202[/tex]
[tex]P(X = 4) = C_{33,4}.(0.11)^{4}.(0.89)^{29} = 0.2041[/tex]
[tex]P(X = 5) = C_{33,5}.(0.11)^{5}.(0.89)^{28} = 0.1463[/tex]
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0214 + 0.0872 + 0.1724 + 0.2202 + 0.2041 + 0.1463 = 0.8516[/tex]
0.8516 = 85.16% probability that fewer than 6 are Independent.
C. What is the probability that more than 2 people are Independent?
This is:
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X < 2) = 0.0214 + 0.0872 = 0.1086[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.1086 = 0.8914[/tex]
0.8914 = 89.14% probability that more than 2 people are Independent.

3. Write an equation for the line that is perpendicular to the given line and that passes through the given point. y = 4x + 1 (12,-6)
a)y = -1/4x + 12
b)y = -1/4x - 3
c)y = -1/4x - 6
d)y= -1/4x + 3
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
If the line is perpendicular, it will have a opposite reciprocal slope.
So, the slope will be -1/4.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
-6 = -1/4(12) + b
-6 = -3 + b
-3 = b
Plug in the slope and y intercept into y = mx + b
y = -1/4x - 3
So, the correct answer is D. y = -1/4x + 3
Answer:
D. y = -1/4x + 3

The tennis team is having a fundraiser for uniforms for its 9 players. The total cost for the uniforms is $759.84 and the team already has $224.36. Write and solve an inequality that represents the amount of money, x, each team member must raise? Input your answer as an inequality with no spaces
Answer:
X ≥ 59.50
Step-by-step explanation:
So to begin, your equation would need to solve for x. X has to be greater than or equal to the minimum amount each player needs to raise for the uniforms. To find how much money they need to raise subtract $224.36 from $759.84 to get $535.48. Divided $535.48 by 9 players to see the minimum amount they each need to contribute. You should get $59.50 roughly. So each player would need to raise greater than or equal to $59.50.

1. Refer to the figure at the right. Line a is parallel to line b and m2 is 135 °. Find each given angle measure. Justify your answer
m9+m<10
m1
m6
m4+ m5
this means angle
Answer:
∠9 + ∠10 = 135° combined, they are alternate equal to ∠2
∠1 =45° it is supplementary to ∠2
∠6 = 45° it is corresponding congruent to ∠8 which is alternate
equal to ∠1
∠4 + ∠5 = 135° combined, they are corresponding congruent to ∠2
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
All the angles are mentioned on the diagram.
The measure of the angles ∠1, ∠6, ∠4, ∠5, ∠9, and ∠10 will be 45°, 45°, 45°, 90°, 45°, and 90°, respectively.
