The division of 5,945 by 612 yields a quotient of 9 with a remainder of 437, which corresponds to option C: 9 R437.
To solve the division problem 5,945 \/ 612, we'll use long division:
First, see how many times 612 fits into 5,945.
Starting from the left, 612 does not fit into 5. We extend it to 59, but 612 doesn't fit into 59 either.
When we take the first three digits, 612 fits into 594 exactly 0 times. So we take one more digit. 612 fits into 5,945 around 9 times because 612 * 9 = 5,508 which is less than 5,945.
Subtract 5,508 from 5,945 to get the remainder. 5,945 - 5,508 = 437.
The quotient is 9 with a remainder of 437, which matches option C: 9 R437.
Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player. Josiah predicted the number of rock songs on his MP3 player to be 300 songs. Which statements about his solution are true? Check all that apply.

He did not multiply the numerator and denominator by the correct number to equal 1,500. His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion. He can only solve the proportion by multiplying the numerator and denominator by a common multiple. He should have multiplied the numerator and denominator by 75, not 30, because 20x75=1,500
Answer:
1) He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
2) He did not multiply the numerator and denominator by the correct number to equal 1,500.
5) He should have multiplied the numerator and denominator by 75, not 30, because 20 x 75 = 1,500.
Step-by-step explanation:
Final answer:
Josiah made errors in predicting the number of rock songs on his MP3 player by not averaging the samples correctly and by using the wrong multiplication factor in his proportion calculation. The correct average should be 5, and he should have used a factor of 75 to scale his samples up to the total number of songs.
Explanation:
The student has used a proportion to predict the number of rock songs on his MP3 player based on a sample. However, the prediction method has a few mistakes that should be corrected for an accurate estimate.
Josiah's initial prediction did not consider averaging the number of rock songs from both samples, which would have given a better representation of the average occurrence in the sample set. The correct average is (4+6)/2 = 5 rock songs per sample.
The proportion set up by Josiah is 10/20 = x/1,500, which implies that the 10 rock songs in his samples represent half of all songs played. This should have been compared to the total number of songs on the MP3 player, 1,500, requiring him to multiply by a specific number. Yet, the multiplication factor used (30) was incorrect. To scale up 20 to 1,500, he should use the factor of 75, because 20 × 75 = 1,500.
The correct proportion should be 5/20 = x/1,500, which simplifies to 1/4 = x/1,500, and then x = 1,500/4 = 375. Hence, the predicted number of rock songs based on the sample should be 375.

For this case we have the following equation:
[tex]\frac {2} {5} * (3r + 4) = 10[/tex]
We must clear the variable "r":
We multiply by[tex]\frac {2} {5} * (3r + 4) = 10[/tex] \ frac {5} {2} on both sides of the equation:
[tex]\frac {2} {5} * \frac {5} {2} (3r + 4) = 10 * \frac {5} {2}\\3r + 4 = \frac {50} {2}\\3r + 4 = 25[/tex]
We subtract 4 on both sides of the equation:
[tex]3r + 4-4 = 25-4\\3r = 21[/tex]
We divide between 3 on both sides of the equation:
[tex]\frac {3r} {3} = \frac {21} {3}\\r = 7[/tex]

which equation can be represented using the number line?
Answer:
First Equation: [tex]\frac{3}{4} \div \frac{1}{8} =6[/tex]
Step-by-step explanation:
From the given number line we can see that there are 6 arrows/jumps of equal sizes to reach from 0 to [tex]\frac{3}{4}[/tex]
Each small jump is equivalent to [tex]\frac{1}{8}[/tex]. This is because from 0 to [tex]\frac{1}{4}[/tex] there are 2 jumps, so 1 jump will be equal to [tex]\frac{1}{4}[/tex] divided by 2 which is equal to [tex]\frac{1}{8}[/tex]
From 0 to [tex]\frac{3}{4}[/tex], 6 jumps of [tex]\frac{1}{8}[/tex] are made. In other words we can say [tex]\frac{1}{8}[/tex] is added to itself 6 times to reach to [tex]\frac{3}{4}[/tex].
Adding [tex]\frac{1}{8}[/tex] 6 times to itself also means multiplying [tex]\frac{1}{8}[/tex] by 6. So we can set up the equation as:
[tex]\frac{1}{8} \times 6 = \frac{3}{4}[/tex]
Dividing both sides by [tex]\frac{1}{8}[/tex] we get:
[tex]6=\frac{3}{4} \div \frac{1}{8} \\\\ or\\\\ \frac{3}{4} \div \frac{1}{8} =6[/tex]
Hence, the first equation represents the given number line.

An outside angle is equal to the sum of the two opposite inside angles.
This means 150 = x + (x+20)
Now solve for X:
150 = x + x+20
simplify:
150 = 2x+20
Subtract 20 from each side:
130 = 2x
Divide both sides by 2:
x = 130/2
x = 65
Now we have X = 65
Solve for the other angle with x in it, by replacing x with 65:
x = 20 = 65 +20 = 85
The three inside angles of a triangle need to equal 180 so now we can solve for Z:
z = 180 - 65 - 85 = 30 degrees.
X = 65, Z = 30

The graphs below have the same shape. What is the equation of the blue graph?
Answer: OPTION B
Step-by-step explanation:
The red graph shows the parent function of a quadratic function (which is the simplest form of a quadratic function), whose vertex is at the origin.
The function g(x) is the result of shift the parent function 2 units to the right and shift it 1 unit up.
Therefore, keeping the above on mind you have that the transformation has the following form:
[tex]g(x)=(x-h)^2+k[/tex]
Where the horizontal shift depends on the value of h and the vertical shift depends on the value of k.
Therefore, you obtain the function:
[tex]g(x)=(x-2)^2+1[/tex]
Answer:
B. [tex]g(x)=(x-2)^2+1[/tex]
Step-by-step explanation:
The equation of the red graph is [tex]f(x)=x^2[/tex].
The blue graph has its vertex at (2,1)
Hence its equation is of the form;
[tex]g(x)=a(x-2)^2+1[/tex]
This graph has y-intercept (0,5).
[tex]5=a(0-2)^2+1[/tex]
[tex]5-1=a(-2)^2[/tex]
[tex]4=4a[/tex]
[tex]1=a[/tex]
The blue graph therefore has equation;
[tex]g(x)=(x-2)^2+1[/tex]
Carla spent two-fifths of her savings on a bracelet and had $\$ 9$ left over. How many dollars did Carla's bracelet cost?
Answer:
The cost of the bracelet was [tex]\$6[/tex]
Step-by-step explanation:
Let
x------> amount of Carla's savings
y-----> the cost of bracelet
we know that
[tex]y=\frac{2}{5}x[/tex] -----> equation A
[tex]1-\frac{2}{5}=\frac{3}{5}[/tex]
so
[tex]9=\frac{3}{5}x[/tex] ----> solve for x
[tex]x=9*5/3=\$15[/tex]
substitute the value of x in the equation A and solve for y
[tex]y=\frac{2}{5}(15)=\$6[/tex]
Answer: $6
Step-by-step explanation:
To find out how much Carla's bracelet cost, we can start by calculating how much of her savings she spent on the bracelet.
We know that Carla spent two-fifths of her savings on the bracelet, and she had $9 left over. This means that the amount she spent on the bracelet is equal to three-fifths of her savings, since she had $9 left over.
To find the value of three-fifths of Carla's savings, we can set up an equation:
$\frac{3}{5} \times \text{savings} = 9$
To solve this equation, we can multiply both sides by $\frac{5}{3}$ to isolate the variable:
$\text{savings} = \frac{9 \times 5}{3} = 15$
So Carla's total savings is $15.
Now we can find the cost of the bracelet by multiplying Carla's savings by the fraction she spent:
$\frac{2}{5} \times 15 = 6$
Therefore, Carla's bracelet cost $6.

Answer:
x = - 7, x = - 4
Step-by-step explanation:
To factor the quadratic
Consider the factors of the constant term ( + 28) which sum to give the coefficient of the x- term ( + 11)
The factors are + 7 and + 4, since
7 × 4 = 28 and 7 + 4 = 11, hence
(x + 7)(x + 4) = 0
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 4 = 0 ⇒ x = - 4
What multiples to 42 and adds to -2
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0

10 - 2(x-y)=3x +1 which shows the equation in standard form ?
5x + 2y= -9
-5x - 2y =9
-5x + 2y= -9
2y = 5x - 9
Step-by-step explanation:
Should be the third choice
Final answer:
The equation in standard form is -9x + 2y = -9.
Explanation:
To show the equation in standard form, we want to rearrange it so that the variables appear on one side and the constants on the other side. Let's start by distributing the 2 to both terms inside the parentheses:
10 - 2x + 2y = 3x + 1
Next, let's combine like terms by adding 2x and subtracting 10 from both sides:
-2x + 2y - 2x + 10 = 3x + 2x + 1 - 10
-4x + 2y + 10 = 5x + 1
Now, let's move the terms involving x to the left side and the constants to the right side:
-4x - 5x + 2y = 1 - 10
-9x + 2y = -9
Therefore, the equation in standard form is -9x + 2y = -9.

Answer:
25.
Step-by-step explanation:
For two complex numbers z=([tex]x_{1},y_{1}[/tex]) and w=([tex]x_{2},y_{2}[/tex]) we have that the distance between z and w is equal to
|z-w| = [tex]\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}[/tex]
So, in this case we have that [tex](x_{1},y_{1})=(2,-3)[/tex] and [tex](x_{2},y_{2})=(9,21)[/tex], then the distance
|z-w| = [tex]\sqrt{(2-9)^{2}+(-3-21)^{2}}[/tex]
= [tex]\sqrt{(-7)^{2}+(-24)^{2}}[/tex]
= [tex]\sqrt{49+576}[/tex]
= [tex]\sqrt{625}[/tex]

The scatterplot shows the distance (in feet) that a person was from a motion sensor during an experiment in math class. Use the labeled points to create a linear model. About what distance in feet (y) would a person be 8 seconds after the experiment begins?
A.) 21ft
B.) 27ft
C.) 30ft
D.) 57ft
Answer:
B.) 27ft
Step-by-step explanation:
The labeled points given: (5,18) and (1.5, 7.5)
Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3
A linear model:
y - 18 = 3(x - 5)
y - 18 = 3x - 15
y = 3x + 3
If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)
y = 3(8) + 3
y = 24 + 3
y = 27 ft
Answer:
B.) 27ft
A person would be at a distance of 27 feet, 8 seconds after the experiment begins.
What is a scatter plot?A scatter plot diagram is a graph in which the coordinates of a point are marked and the regression or correlation between these points is observed.
A linear model for the given scatter plot can be made as shown below:The labeled points that are given are (5,18) and (1.5, 7.5)
m = Slope of the given scatter plot = (18 - 7.5)/(5 - 1.5)
= 10.5 / 3.5
= 3
The linear model of the scatter plot can be found by substituting the values of x and y using the labelled coordinates.
y - y_1 = m( x - x_1 )
y - 7.5 = 3(x - 1.5)
y - 7.5 = 3x - 4.5
y = 3x - 4.5 + 7.5
y = 3x - 3
The value of x is given as 8. Substitute x in the equation above:
y = 3(8) + 3
y = 24 + 3
y = 27 feet
Therefore, a person would be at a distance of 27 feet, 8 seconds after the experiment begins. The correct answer is option B.

Sanjay needs 90 meters of fence to go around a rectangular garden.
The length l of the garden is three times its width w.
Three of these equations give the correct value for w.
Which equation does NOT?
Answer:
Option A is incorrect.
Step-by-step explanation:
Length of the given parts is l and width is w meters.
It is given in the question that Sanjay needs 90 meters of fence to go around the rectangular park.
It means perimeter of the park is 90 meters.
Since perimeter of a rectangle = 2(length + width)
= 2(L + w)
It is given that length of garden is three times of width so l = 300
therefore, equation will be
Perimeter = 2[3w + w]
90 = 2[3w + w]
Option A ⇒ w + 3w = 90 ⇒ incorrect
Option B ⇒ w + 3w + w + 3w = 90
2(w + 3w) = 90 ⇒ Correct option
Option C ⇒ 2w + 2 (3w) = 90
2 [w + 3w] = 90 ⇒ Correct option
Option D ⇒ 2(3w + w) = 90 ⇒ Correct option
therefore Option A is incorrect option.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 7 to 4. If there were 6125 yes votes, what was the total number of votes?
Answer:
3,500 no votes
Step-by-step explanation:
There were 7 yes votes to every 4 no votes. There were a total of 6,125 yes votes, so set up a proportion to find the number of no votes
Let x represent the number of no votes
7 is to 4 as 6,125 is to x
We get
7/4 = 6,125/x
Now solve for x
First cross multiply
7x = 24,500
Divide both sides by 7 to isolate x..
x = 3,500 no votes
