The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of
a right cylinder that has the same base and height as the cone?
Answer:
900 cubic inches.
Step-by-step explanation:
Given the following data
Volume of right circular cone = 300in³
We know that the volume of a right circular cone is given by the formula;
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of right circular cone.r is the radius of the base of the right circular cone.h is the height of the right circular cone.The volume of a right circular cylinder is given by the formula;
[tex] V = \pi r^{2}h[/tex]
Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.
[tex] V = \frac{1}{3} \pi r^{2}h * 3[/tex]
Substituting into the equation, we have;
V = 300 * 3
V = 900in³
Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

Hi. I need help with these questions.
See image for question.
Answer:
a = 3, b = 2Step-by-step explanation:
GivenP(x) = ax² + bx + 1P(1) = 6 and P(-1) = 2To find Values of a and bSolutionSubstitute the values of x:
P(1) = 6
6 = a(1)² + b(1) + 16 = a + b + 1a + b = 5P(-1) = 2
2 = a(-1)² + b(-1) + 12 = a - b + 1a - b = 1a = b + 1Substitute a in the previous equation:
a + b = 5b + 1 + b = 52b = 4b = 2Then finding a:
a = b + 1a = 2 + 1 a = 3So a = 3, b = 2
Solve for x
(x/b)-y=3
Answer:
x = by + 3b

20+3m=5m What does m equal?
Answer:
M= 10
Step-by-step explanation:
I edited it so now it should be right
Answer:
m = 10
Step-by-step explanation:
20 + 3m = 5m
Subtract 20 from both sides
3m = 5m - 20
Subtract 5m on both sides
-2m = -20
Divide both side by -2
-2m/-2 = -20/-2
= m = 10

18 / x equals negative 2
Answer:
x = -1/9
Step-by-step explanation:
[tex]\frac{18}{x} = -2[/tex] multiply by 1/18 to cancel out
[tex]x = -2(\frac{1}{18} )\\x = -\frac{2}{18} \\x = -\frac{1}{9}[/tex]
Hey there!
18/x = -2
Multiply both sides by x
-2x = 18
Divide both of your sides by -2
-2x/-2 = 18/-2
Cancel out: -2x/-2 because it gives you 1
Keep: 18/-2 because it helps us solve for our answer
x = 18/-2
18/-2 = 18 divided by -2 ➡️ -9
Thus your answer is: x = -9 ✅
Good luck on your assignment and enjoy your day!

Which equation represents a line parallel to the y-axis?
A. y = x
B. x = 4
C. y = 4
D. y = x +4
The equation of the line that is parallel to the y-axis is option B. x = 4
What are parallel lines:Parallel lines are two or more lines that are always the same distance apart and never intersect, even if they are extended infinitely in both directions.
In other words, they have the same slope but different y-intercepts, which means that their steepness or inclination is the same.
Note:
The equation of the line that is parallel to the x-axis is y = a. The equation of the line that is parallel to the y-axis is x =aBy the above observations
The equation of the line that is parallel to the y-axis is x = a
From the given options,
The equation of the line that is in the form of x = a is x = 4
Therefore,
The equation of the line that is parallel to the y-axis is option B. x = 4

A police car is approaching a right-angled intersection from the north at 35 mph, and a speeding car is heading east at 30 mph. When the police car is 0.75 miles north of the intersection and the speeding car is 1 mile to the east, what is the rate that the distance between the police car and car is changing?
Answer:
The rate that the distance between the police car and car is changing = 3 m/s
Step-by-step explanation:
The given speed of the police car = 35 mph
The speed of the speeding car = 30 mph
The position of the police car = 0.75 miles north
The position of the speeding car = 1 miles east
The distance of the police car from the speeding car, d = √(0.75² + 1²) = 1.25
d² = x² + y²
2d·dd/dt = 2x·dx/dt + 2·y·dy/dt
Where;
dx/dt = 30 mph
dy/dt = -35 mph
x = 1
y = 0.75
Substituting gives;
2×1.25 ×dd/dt = 2×1×30 - 2×0.75×35
2×1.25 ×dd/dt = 7.5
dd/dt = 7.5/2.5 = 3
dd/dt = 3 m/s
The rate that the distance between the police car and car is changing = dd/dt = 3 m/s
Answer:
The answer is increasing by 3 mph

Selma cannot remember her locker number! She knows that her locker number is prime, and that it is a factor of 435. What are all of Selma's possible locker numbers?
Answer:
Possible locker numbers for Selma are: 3, 5 and 29
Step-by-step explanation:
First of all, let us have a look at the definition of a prime number.
A prime number is a number which is divisible either by 1 or the number itself.
No other number divides the prime number other than 1 and the number itself.
Now, let us factorize the given number 435 and let us observe the what all possibilities are there.
[tex]435 = 3\times 145[/tex]
Factorizing 145 further:
[tex]435 = 3\times 5\times 29[/tex]
No further factors are possible.
Therefore 3, 5 and 29 are the prime factors of 435.
So, the answer is:
Possible locker numbers for Selma are: 3, 5 and 29
