The correct answer is option B which is [tex]4,072 cm^3[/tex]
Step-by-step explanation:
Given:
The dimensions of the cylinder,
Radius (r) = 12 cm
Height (h) = 9 cm
To find:
The volume of cylinder.
Formula:
Volume of the cylinder = [tex]\pi r^{2} h[/tex]
If r = 12 cm and h = 9 cm then the volume of the cylinder can be found by using the formula as,
Volume of the cylinder = [tex]\pi (12^{2}) (9)[/tex]
= [tex]4071.5 cm^3[/tex]
≈ 4072 cm³
So it is closest to the answer B, 4,072 cm³.

What is the angle of a triangle if one angle is 68 and the other is 52
Answer:
The last angle is 60 degrees
Step-by-step explanation:
All triangles add up to 180 degrees
Step 1: Make an equation
What is the angle of a triangle if one angle is 68 and the other is 52.
68 + 52 + x = 180
Step 2: Combine like terms
68 + 52 + x = 180
120 + x = 180
Step 3: Subtract 120 from both sides
120 + x - 120 = 180 - 120
x = 60
Answer: The last angle is 60 degrees
The sum of the angles in a triangle will be equal to 180°.
68 + 52 = 120°
180 - 120 = 60° (This is the 3rd angle)

between the time Iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14 °. Write an addition expression for the temperature relative to when Iko woke up.
Answer:
x + (11) + (-14) [x being temperature when Iko woke up]
Step-by-step explanation:
Let the temperature be "x" when Iko woke up
Then,
Temperature ROSE 11° in lunch
The temp in lunch was: x + 11
Then the temperature DROPPED 14° when he went to bed, relative to lunch temperature, so we can say:
(x + 11) - 14
So, the final temperature that end of day was:
x + 11 - 14
As addition expression, it will be:
x + (11) + (-14)

The circumference of a circular frisbee is 20 centimeters. If
we multiply the radius of the frisbee by 5, what will be the
circumference of the new frisbee?
OA) 981 cm
OB) 100 cm
OC) 1451 cm
OD 2007 cm
Answer:
100cm
Step-by-step explanation:
since the circumference is 20cm and formula for finding a circumference of a circle is c=2(pi)r, where r is radius and pi is constant value which is equivalent to 22/7. so the radius of 20cm circumference is 3.1847 by using this eqn c/2(pi)=r. now the calculated radius will b multiply by 5 to get 15.92cm which is put in cirumference formula i.e. c=2(pi)r we get 100cm circumference.

[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
y = mx also represents direct proportionality. We can write [m] as -
m = y/x
OR
y₁/x₁ = y₂/x₂
Given is a straight line.
The equation of a straight line is written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Now, from this we get -
m = -A/B {Slope}
c = - C/A {y - intercept}
So, the equation will be -
y = mx + c
We can also calculate slope by -
m = (y₂ - y₁)/(x₂ - x₁)
Therefore, we can write -
m = -A/B → unit rate of change of [y] with respect to [x].
c = - C/A → the point where the graph cuts the [y] axis.

9.0758 to 2 significant figures.
Answer w/ explanation:
The answer is 9.1
To round to 2 significant figures, we have to find the first significant figure. We find the first sig fig by looking for the first nonzero digit in the number (it can be before or after the decimal point), which is "9"
The next digit is "0". This will also be a significant figure in our answer.
It may seem we are done now since we found the two significant figures. However, let's look at the digit after "0" to see if we need to round up or down.
The digit after "0" is "7". Since 7 is greater than 5, we round up the "0" to a "1" in our final answer, making the answer 9.1
Side note:
The definition and concept of significant figures can be very confusing overall, so please continue to ask questions if you are still struggling with them.

1. Find the x-intercept of the line: 5x - y = 10
2. Find the y-intercept of the line: 9x + 3y = -18
3. What are the x- and y- intercepts of the graph of 6x - 4y = -12
Final answer:
The x-intercept of the line 5x - y = 10 is (2, 0), the y-intercept of the line 9x + 3y = -18 is (0, -6), and the equation 6x - 4y = -12 has an x-intercept at (-2, 0) and a y-intercept at (0, 3).
Explanation:
To find the x-intercept of a line, we set the value of y to zero and solve for x. For the equation 5x - y = 10, we set y to 0:
5x - (0) = 10
5x = 10
x = 2
The x-intercept is therefore the point (2, 0).
To find the y-intercept of a line, we set the value of x to zero and solve for y. For the equation 9x + 3y = -18, we set x to 0:
(0) + 3y = -18
3y = -18
y = -6
The y-intercept is therefore the point (0, -6).
For the equation 6x - 4y = -12, the x-intercept and y-intercept can be found similarly. Let's start with the x-intercept. Set y to 0:
6x - (0) = -12
6x = -12
x = -2
The x-intercept is the point (-2, 0). Now, for the y-intercept, we set x to 0:
(0) - 4y = -12
-4y = -12
y = 3
The y-intercept is the point (0, 3). Thus, for 6x - 4y = -12, the intercepts are x = -2 and y = 3.

There are 27 girls and 36 boys who want to participate in a math competition. If each team must have the same ratio of girls and boys what’s the greatest number of teams that can enter?
Since the ratio of girls and boys must be the same in each team, and all the competitors must be involved, it means that each team's ratio of boys : girls must be equal to the total ratio of Boys : Girls = 36 :27= 4 / 3.
Now 4 / 3, the most simplified version of 36 / 27, happens by dividing the numerator & demoninator by 9 (the greatest number it can divide by). So the greatest number will be 9 teams, each of 4 Boys & 3 Girls

Which best describes the graphs of the line that passes through (−12, 15) and (4, −5), and the line that passes through (−8, −9) and (16, 21)?
A)
They are parallel lines.
B)
They are vertical lines.
C)
They are perpendicular lines.
D)
They are intersecting lines.
Answer:
C) They are perpendicular lines.
Step-by-step explanation:
We first need to find the slope of the graph of the lines passing through these points using:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
The slope of the line that passes through (−12, 15) and (4, −5) is
[tex] m_{1} = \frac{ - 5 - 15}{4 - - 12} [/tex]
[tex]m_{1} = \frac{ - 20}{16} = - \frac{5}{4} [/tex]
The slope of the line going through (−8, −9) and (16, 21) is
[tex] m_{2} = \frac{21 - - 9}{16 - - 8} [/tex]
[tex] m_{2} = \frac{21 + 9}{16 + 8} [/tex]
[tex]m_{2} = \frac{30}{24} = \frac{5}{4} [/tex]
The product of the two slopes is
[tex]m_{1} \times m_{2} = - \frac{4}{5} \times \frac{5}{4} = - 1[/tex]
Since
[tex]m_{1} \times m_{2} = - 1[/tex]
the two lines are perpendicular.
