Answer: let
Total number of those who took part in the survey (T)=3200
Those who were satisfied (t)=960
Percentage of those who were satisfied (S)=(t/T)*100
S=(960/3200)*100
S=30%
Therefore only 30% were satisfied
Step-by-step explanation:
Thirty percent of the people surveyed were satisfied with the car.
What is the formula used to find the percentage?The formula used to calculate percentages is the ratio of value to total value multiplied by 100.
Let's denote T as the total number of people who owned a certain type of car and t as the number of people who were satisfied with the car.
Given that,
T =3200
t= 960
The percent of people satisfied with the car is obtained by using the below equation.
[tex](\frac{t}{T} ) * 100[/tex]
(960/3200)*100 = 30%
As a result, the percentage of people who are satisfied with the car is 30%.

Please help:( i don't understand this question Kendall’s benchmark test scores are the following: 89, 79, and 93. She has to take her fourth and final benchmark on June 6 th . She really wants to get an A in the class and in order to do so she must have an average of a 90. If Kendall’s teacher decides to count the final exam as two test grades, what would she need on the final test to make sure she gets an A?
Hey there!
The answer to your question is 94.5
We can use this equation, and solve: (we need to use "2x" because the score counts for 2 grades!)
(89 + 79 + 93 + 2x) / 5 = 90
(261 + 2x) / 5 = 90
261 + 2x = 450
2x = 189
x = 94.5
To check if it's right, we can add up all the scores, and divide by 5, and see if it's equal to 90. (Make sure to use 94.5 twice because it counts for 2 test grades!)
(89 + 79 + 93 + 94.5 + 94.5) / 5
450 / 5
90 ✔️
Hope it helps! Have a great day and good luck!

Answer:
-2.05, in fraction form it would be -2 1/20
Answer:
-41/20
Step-by-step explanation:
Hi there!
From the question, I believe you’re asking [tex]\frac{3}{4}[/tex] - [tex]2 \frac{4}{5}[/tex]
First, put the whole number 2 back into the fraction to create an improper fraction.
This would become [tex]\frac{14}{5}[/tex]. Now, we have to find a common denominator between the two fractions. Both 4 and 5 can go into 20, so that will be our common denominator. To turn [tex]\frac{3}{4}[/tex] into a fraction with a denominator of 20, we have to multiply both the numerator and denominator by 5. [tex]\frac{3}{4}[/tex] becomes [tex]\frac{15}{20}[/tex]. We do the same thing for [tex]\frac{14}{5}[/tex] except we multiply the numerator and denominator by 4. We end up with [tex]\frac{56}{20}[/tex]. Now we just have to subtract!
[tex]\frac{15}{20} - \frac{56}{20}[/tex] leaves us with [tex]- \frac{41}{20}[/tex] , which can’t be simplified any further.

K
M
22
L X= ?
Answer:
The value of x is 2
Step-by-step explanation:
In the parallelogram, every two opposite sides are equal in lengthsLet us solve the question
In the given figure
∵ LMNK is a parallelogram
∵ ML and NK are opposite sides
→ By using the rule above
∴ ML = NK
∵ ML = 22
∵ NK = 12x - 2
→ Equate them
∴ 12x - 2 = 22
→ Add 2 to both sides
∵ 12x - 2 + 2 = 22 + 2
∴ 12x = 24
→ Divide both sides by 12
∴ x = 2

In circle M with m \angle LMN= 98m∠LMN=98 and LM=18LM=18 units, find the length of arc LN. Round to the nearest hundredth.
Answer:
To the nearest hundredth, this is 30.79 units
Step-by-step explanation:
To find the length of the arc, we simply apply the length of arc formula
Mathematically, that would be;
theta/360 * 2 * pi * r
Theta here is 98
r is 18 units
So the length of the arc will be;
98/360 * 2 * 22/7 * 18
= 30.7876 units
to the nearest hundredth, this is;
30.79 units
Identify the slope and the y - intercept of the graph below.
What does the 180 mean in this (n-2)180 and why do we multiply it
Answer:
Polygons can be separated into triangles by drawing all the diagonals that can be drawn from one single vertex. If you look back at the formula, you'll see that n – 2 gives the number of triangles in the polygon, and that number is multiplied by 180, the sum of the measures of all the interior angles in a triangle.
A quadratic function is defined by
g(x) = (x + 4)2 + 7
1. What is the vertex of the graph of function g?
2. Does the vertex represent the minimum value or the maximum value of the function?
Explain or show how you know.
3. If you were to shift this graph 6 units down from where it is now, what would be the equation represented by the new graph?
Answer:
1. The vertex of the graph of the function is (-4, 7)
2. The vertex represents a minimum value
3. The equation represented by the new graph is g(x) = (x + 4)² + 1
Step-by-step explanation:
The given quadratic function is given in vertex form, y = a·(x - h)² + k, as follows;
g(x) = (x + 4)² + 7
1. By comparing the given quadratic function and the vertex form of a quadratic equation, we have;
a = 1, h = -4, and k = 7
The vertex of the graph of the function, (h, k) = (-4, 7)
2. Given that a = 1 > 0, the graph of the quadratic function opens upwards and the vertex represents a minimum value
3. Shifting the graph 6 units down from where it is now will give;
The vertex = (h, k - 6) = (-4, 7 - 6) = (-4, 1)
h = -b/(2·a), k = (-b²/(4·a) + c = -a·h² + c
c = k + a·h²
Therefore, initial value of the constant term, c = -1×(-4)² + 7 = 23
After the shifting the graph 6 units down, c = 23 - 6 = 17
∴ k = 1 = -a·(-4)² + 17
∴ -16/16 = -1 = -a
a = 1
Therefore, the equation represented by the new graph is g(x) = (x + 4)² + 1.
1. The vertex of the graph of the function is (-4, 7)
2. The vertex represents a minimum value
3. The equation represented by the new graph is g(x) = (x + 4)² + 1
What is a graph?
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given quadratic function is given in vertex form, y = a·(x - h)² + k, as follows;
g(x) = ( x + 4 )² + 7
1. By comparing the given quadratic function and the vertex form of a quadratic equation, we have;
a = 1, h = -4, and k = 7
The vertex of the graph of the function, (h, k) = (-4, 7)
2. Given that a = 1 > 0, the graph of the quadratic function opens upwards and the vertex represents a minimum value
3. Shifting the graph 6 units down from where it is now will give;
The vertex = (h, k - 6) = (-4, 7 - 6) = (-4, 1)
h = -b/(2·a), k = (-b²/(4·a) + c = -a·h² + c
c = k + a·h²
Therefore, initial value of the constant term, c = -1×(-4)² + 7 = 23
After the shifting the graph 6 units down, c = 23 - 6 = 17
∴ k = 1 = -a·(-4)² + 17
∴ -16/16 = -1 = -a
a = 1
Therefore, the equation represented by the new graph is g(x) = (x + 4)² + 1.

I have the inequality 120A + 100B <= 220 how do i graph this?
Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
Answer:
See below
Step-by-step explanation:
Given inequality
120a + 100b ≤ 220This is a linear inequality, to graph first find intercepts:
a- intercept, when b = 0
120a = 220a = 220/120 = 1.833b- intercept, when a = 0
100b = 220b = 220/100 = 2.2We got two points:
(1.833, 0) and (0, 2.2)Now graph this with following steps
1. Plot these points on the coordinate plane. 2. Construct a solid line passing through those two points. (it would be dotted line is inequality sigh was > or < )3. Shade the area left to the line. (it would be the area to right if inequality sign was ≥)The graph is attached
