Out of all 252 twelfth graders, how many rode in a car to school?
Answer:
D) 114
Step-by-step explanation:
got it right on edge
Out of all 252 twelfth graders, the number of students that rode in a car to school is 114.
How many twelfth graders rode in a car to school?The first step is to determine the total number of students that rode a bicycle to school
Students that rode a bicycle to school = 815 - (276 + 196 + 314) = 29
The second step is to determine how many twelfth graders rode a bicycle to school: 29 - (8 + 10) = 11
Number of twelfth graders that rode a car to school = 252 - (99 + 11 + 28) = 114

A circle has a circumference of 12.It has an arc length 11. What is the central angle of the arc,in degrees?
Answer:[tex]330^{\circ}[/tex]
Step-by-step explanation:
Given
Circumference of circle [tex]C=12\ units[/tex]
Arc length [tex]l=11\ units[/tex]
we know arc length is given by
[tex]l=\frac{\theta }{360^{\circ}}\times 2\pi r[/tex]
substituting value we get
[tex]11=\frac{\theta }{360}\times 12[/tex]
[tex]\frac{11}{12}=\frac{\theta }{360}[/tex]
[tex]\therefore \ \theta =330^{\circ}[/tex]
The central angle of the arc is approximately 330 degrees.
The question involves finding the central angle of an arc in degrees when the circumference of the circle is 12 and the arc length is 11. To solve this, it's essential to understand the relationship between the arc length, the central angle, and the circumference of the circle.
The formula we use is (Central Angle in degrees) / 360 = Arc Length / Circumference. Given that the circumference is 12 and the arc length is 11, we can substitute these values into the formula to find the central angle.
Thus, the calculation is as follows: (Central Angle in degrees) / 360 = 11 / 12.
By cross-multiplication, we find that the
Central Angle in degrees = (11 / 12) × 360.
This gives us a central angle of approximately 330 degrees.
A pizza with a diameter of 13 inches is cut into 12 equal slices. Jayden eats of the pizza, representing an area o Select one square inches. Carson eats 5 slices of pizza, representing an area of Select one square inches.
The complete question is
A pizza with a diameter of 13 inches is cut into 12 equal slices. Jayden eats 1/3 of the pizza, representing an area of ____ square inches. Carson eats 5 slices of pizza, representing an area of ____ square inches.
Answer:
Jayden consume pizza with an area of 44.2498 inches squared.
Carsen consumes pizza with an area of 55.3125 inches squared
Step-by-step explanation:
Diameter is 13 inches,
Radius is diameter divided by 2
Radius = 13/2 = 6.5 inches
Area = pi times radius squared
Area = 3.142 x 6.5^2 = 132.7495.
For jayden, 1/3 of this will be
1/3 x 132.7945 = 44.2498 inches squared.
For carsen, the 12 slice of pizza will each have an area of 132.7945/12 = 11.0625 inches squared,
5 of those slices will have area of 5 x 11.0625 = 55.3125 inches squared.

The polynomial f(x) is written in factored form:
f(x) = (x - 9)(x + 12)(x - 24)
What are the zeros of the polynomial function?
Ox=-9, x = 9, x = -12, x = 12, x = -24, x = 24
O x = -9, x = 12, x= -24
x = 9, x= -12, x = 24
x = 9, x= 12, x = 24
Answer:
{-12, 9, 24}
Step-by-step explanation:
Set the given f(x) = (x - 9)(x + 12)(x - 24) = to 0. Then, one by one, set each factor = to 0 and solve for x: We get the zeros {-12, 9, 24}
Answer: x = 9, x = −12, x = 24

HOW TO DETERMINE SLOPE AND Y-INTERCEPT: Use the instructions below to answer this question.
EQUATION: y=[tex]\frac{-3}{4}[/tex]x-3
-------------------------------------------------
INSTRUCTIONS:FINDING THE Y-INTERCEPT:
Do this simply by finding the number your graph starts at on the Y-Axis (vertical line)! In this case, it's at -3!
FINDING SLOPE:
Remember that slope is rise over run ([tex]\frac{rise}{run}[/tex])
RISE = How far the line goes up and down.
RUN = How far the line goes left or right.
HOW DO I FIND IT? All you have to do is count both rise and run from one point on the line to another! WARNING: The point must hit at a vertex, it cannot be counted if it is in the center of the box, or anywhere that does not touch the edge. I also suggest starting from the Y-Intercept and counting.
GOING LEFT OR DOWN: This is a positive number
GOING RIGHT OR UP: This is a negative number.
(You will see how this applies, below, yayyyy)
CALCULATING OUR NUMERATOR, AKA RISE:
Starting from the y, to get to the next point on the line, you can see we have to go down three. This means our numerator is -3!
CALCULATING OUR DENOMENATOR, AKA RUN:
Starting from where we just stopped, we must continue getting to the next point, and to do that, you can see we have to go to the right four! This means our denomenator is 4!

Denise went bowling with her friends at AMF. She paid $3 to rent shoes and then $4.75 for each game of bowling. If she spent a total of $22, then how many games did Denise bowl?
Answer: 4 games
Step-by-step explanation:
Whether Denise bowls or not, he incurs rent for bowling shoes and per bowling he has to pay $4.75 while he rented shoes for $3.
Then the equation is:
y = 3 + 4.75x
Where
y is the total cost
x is Number of bowling
y = 3 + 4.75x
3 + 4.75x = 22
4.75x = 22 - 3
4.75x = 19
x = 19/4.75
x = 4
Denise bowled 4 games.
Final answer:
To determine the number of games Denise bowled, an equation was set up using the cost of shoe rental and per game cost, and solved algebraically. Denise bowled 4 games.
Explanation:
The subject of this question is Mathematics, specifically focusing on simple algebra and solving equations. Denise's total expense for bowling is composed of a fixed cost for shoe rental and a variable cost for the games she played. The total cost is the sum of these two amounts. We can set up an equation to find out how many games she played:
Let x be the number of games Denise bowled. The cost of shoe rental is a fixed $3, and the cost per game is $4.75. So, the equation representing the total cost is:
3 + 4.75x = 22
Now, we will solve for x:
Subtract 3 from both sides of the equation:4.75x = 22 - 34.75x = 19Divide both sides by 4.75 to isolate x:x = 19 / 4.75x = 4Therefore, Denise bowled 4 games. This is a typical middle school algebra problem involving linear equations and is a good example of applying math skills to real-life situations such as budgeting and planning.

The length of a rectangle is 7 inches longer than its width. If the area of the
rectangle is 144 square inches, what are the dimensions?
The dimensions of the rectangle are 9 inches (width) and 16 inches (length) as obtained from solving the quadratic equation derived from the facts provided.
Explanation:To solve this problem, let's denote the width of the rectangle as x in inches. Since we know that the length of the rectangle is 7 inches longer than its width, we can write it as x + 7 inches. The area of a rectangle is calculated by multiplying its length by its width. Here, it's given as 144 square inches.
Setting up the equation for the area, we get x(x + 7) = 144.
Solving this quadratic equation, we find that x = 9. As a result, the width is 9 inches and the length, being 7 inches longer, is 16 inches. Therefore, the dimensions of the rectangle are 9 inches by 16 inches.
