Help ASAP please
Answer: 6
Step-by-step explanation:
ab:pq = 5:35, and ac:pr=x:42
because ab:pq=5:35, then it becomes 1:7, as you can divide by 5 on both sides. Ac:pr=x:42, and 42=7x. When you solve that x=6.
hope that makes sense!

Ann had 96 filers to post around town. Last week, she posted 1/4 of them. This week, she posted 1/3 of the remaining filers. How many filers has she still not posted
Answer:
48 [fliers]
Step-by-step explanation:
Ann starts with 96 fliers. After she posts 1/4 of them, she will have 3/4*96=72 fliers left. She now has 72 remaining flyers. After posting 1/3 of these, she will have 2/3*72=48 fliers left.
Which function has the greater maximum value: f(x) = -3x2 + 6x + 4, or g(x),
the function in the graph?
Answer: f(x)
Step-by-step explanation:
The function g(x) has the greater maximum value. So, option (A) is the correct answer.
What is the graph of a function?"The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation".
For the given situation,
The function f(x) is expressed as -3x^2 + 6x +4
The function g(x) is shown in the graph.
Plot the function f(x) in the graph to compare with g(x).
The graph for f(x) is shown below.
The function f(x) is the decreasing function, so it has only a minimal value.
The function g(x) is the increasing function, so it has a maximum value.
Hence we can conclude that the function g(x) has the greater maximum value. So, option (A) is the correct answer.

Step-by-step explanation:
Given
See attachment for box plots
Required
Which of the options is true?
Option A compares the IQR of both plots.
IQR is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
Where
[tex]Q_1 \to[/tex] Lower quartile
[tex]Q_2 \to[/tex] Upper quartile
From the attached plots, we have:
Republican
[tex]Q_1 = 170.5[/tex]
[tex]Q_3 = 356[/tex]
So:
[tex]IQR = 356 - 170.5[/tex]
[tex]IQR = 185.5[/tex]
Democratic
[tex]Q_1 = 181[/tex]
[tex]Q_3 = 367.5[/tex]
So:
[tex]IQR = 367.5 - 181[/tex]
[tex]IQR = 186.5[/tex]
We have:
[tex]IQR = 185.5[/tex] --- Republican
[tex]IQR = 186.5[/tex] --- Democratic
Hence, (a) is true

In a survey, 80 percent of those
surveyed had at least one brother or
sister. What fraction of those surveyed
had at least one brother or sister? Write
your answer in the simplest form.
Answer:
4/5
Step-by-step explanation:
If we are given this value as a percent we can simply turn that percentage into a fraction. 80% would be 8/10 but since the question wants the fraction in simplest form we can achieve this by dividing both the numerator and denominator by 2. This would give us 4/5, which if we divide the numerator by the denominator we get 0.80 which is 80%. Therefore, the fraction of those surveyed that had at least one brother or sister is 4/5
70.5 is what percent of 94
Answer:
75%

Answer:
To graph the equation, you need to find the slope and y-intercept.
y = mx + b
⬑[slope-intercept formula; m is the slope, and b is the y-intercept]
y = 4x + −1
⬑[given equation before being simplified]
y = 4x − 1
⬑[given equation]
║m = 4
║b = (0, −1)
Proof:
m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
x₁ = 0
x₂ = 1
y₁ = −1
y₂ = 3
m = [tex]\frac{3 - -1}{1 - 0}[/tex]
║m = 4
║b = (0, −1)
[the value for x₁ and y₁ equals the y-intercept: (0, −1)]

25. Kendra owns a toy store. She charges $5.00 for two cars and one piece of candy. She charges \$3.2 for one car and one piece of candy. How much does Kendra charge per car?
Kendra's charge per car in the toy store is $1.8.
What is the system of equations?"Systems of equations, sometimes called simultaneous equations, are a group of relationships between various unknown variables that can be expressed in terms of algebraic expressions".
For the given situation,
Let the number of cars be 'x' and
The number of candy be 'y'
$5.00 for two cars and one piece of candy
$3.2 for one car and one piece of candy
System of the equation for the above case
Equation 1:
[tex]2x + y = 5[/tex]
Equation 2:
[tex]x + y = 3.2[/tex]
Subtract equation 2 from equation 1,
⇒ [tex]x=1.8[/tex]
On substituting x in equation 2, we get
⇒ [tex]y=3.2-1.8[/tex]
⇒ [tex]y=1.4[/tex]
Hence we can conclude that Kendra's charge per car is $1.8.

If the if a cylinder is 7 in tall and has a volume of 63 Pi inches what is the area of the cross section it goes right down the middle
Answer: [tex]9\pi \ in.^2[/tex]
Step-by-step explanation:
Given
The height of the cylinder is [tex]h=7\ in.[/tex]
The volume of the cylinder is [tex]V=63\pi \ in.^3[/tex]
The volume of the cylinder is the product of area and height
[tex]\Rightarrow V=\pi r^2h\\[/tex]
Insert the values
[tex]\Rightarrow 63\pi =A\times 7\\\\\Rightarrow A=\dfrac{63\pi}{7}\\\\\Rightarrow A=9\pi\ in.^2[/tex]
Thus, the area of the cross-section is [tex]9\pi \ in.^2[/tex]
