A cake is shaped like a cylinder with a diameter of 9 in. The height of the cake is 6 in.
What is the exact volume of the cake?
Enter your answer in the box.
pi in^3
Answer: 121.5 pi in^3 or 381.7 in^3
Step-by-step explanation:
Volume of a cylinder = pi r^2(h)
Radius = 4.5 in, Height = 6 in
pi (4.5)^2(6)
pi(20.25)(6)
121.5 pi in^3 or 381.7 in^3
The exact volume of a cylindrical cake with a diameter of 9 inches and a height of 6 inches is 121.5π cubic inches.
The volume of a cylinder can be found using the formula V = πr^2h, where V stands for volume, r is the radius of the base of the cylinder, and h is the height of the cylinder. Given the diameter of the cake is 9 inches, the radius is half of that, which is 4.5 inches. Therefore, the exact volume of the cake is calculated as follows:
V = π × (4.5 )² ×2 × 6
Which simplifies to:
V = π × 20.25 ×2 × 6
So, the exact volume of the cake is:
V = 121.5π in^3

Use the figure below to find the value of x and y
Answer:
[tex]x=4, y=8[/tex]
Step-by-step explanation:
step 1
Find the value of y
we know that
In the right triangle of the figure
[tex]cos(30\°)=\frac{4\sqrt{3}}{y}[/tex]
Remember that
[tex]cos(30\°)=\frac{\sqrt{3}}{2}[/tex]
so
[tex]\frac{\sqrt{3}}{2}=\frac{4\sqrt{3}}{y}[/tex]
Simplify
[tex]y=8\ units[/tex]
step 2
Find the value of x
In the right triangle of the figure
[tex]sin(30\°)=\frac{x}{8}[/tex]
Remember that
[tex]sin(30\°)=\frac{1}{2}[/tex]
so
[tex]\frac{1}{2}=\frac{x}{8}[/tex]
[tex]x=4\ units[/tex]
For every $10 worth of candy student council sells, they get to keep $5. This can be represented with variables.
1. What are the variables?
2. What letter can you use to represent each?
3. How are they related>
4. Create an equation relating them to each other. One that you could use to find out the amount of money student council will make for any amount of candy they sell.
1. The variables are “money sold total ($10)” and “money kept by student council($5)”
2. The “money sold total ($10)” can be represented by T. (For Total)
The “money kept by student council($5)” can be represented by K. (for kept)
3. As T increases, K increases.
4. K= t/2
Good luck!
The variables in this problem are the amount of candy sold and the amount of money student council keeps. They are related by the equation m = 0.5c. This equation allows us to find out the amount of money student council will make for any amount of candy they sell.
Explanation:The variables in this problem are the amount of candy sold and the amount of money student council keeps.
We can represent these variables with the letters 'c' for candy sold and 'm' for money kept by student council.
The relationship between the variables is that for every $10 worth of candy sold, student council keeps $5. So, the amount of money student council keeps is half of the amount of candy sold.
We can express this relationship with the equation m = 0.5c.
This equation allows us to find out the amount of money student council will make for any amount of candy they sell.
For example, if they sell 20 worth of candy, we can substitute c = 20 into the equation and solve for m: m = 0.5(20) = 10.
Therefore, student council will make $10 for selling $20 worth of candy.
Graph the line with slope2/3 passing through the point(-2, 1)
Answer:
The graph in the attached figure
Step-by-step explanation:
step 1
Find the equation of the line into point slope form
The equation of the line is equal to
[tex]y-y1=m(x-x1)[/tex]
substitute the given values
[tex]y-1=(2/3)(x+2)[/tex]
step 2
To graph the line find the intercepts
Find the y-intercept
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
[tex]y-1=(2/3)(0+2)[/tex]
[tex]y=(4/3)+1[/tex]
[tex]y=(7/3)[/tex]
The y-intercept is the point (0,7/3)
Find the x-intercept
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
[tex]0-1=(2/3)(x+2)[/tex]
[tex]-1=(2/3)x+(4/3)[/tex]
[tex](2/3)x=-(4/3)-1[/tex]
[tex](2/3)x=-(7/3)[/tex]
[tex]2x=-7[/tex]
[tex]x=-7/2[/tex]
The x-intercept is the point (-7/2,0)
step 3
Plot the intercepts to graph the line

What is 2% of 50??????
Answer:
1
Step-by-step explanation:
2%= 0.2
0.2*5= 1
When finding Percent of whole multiply.
To figure this out you must do a proportion. Typically you would do [tex]\frac{part}{whole}[/tex]
This means that you would set up your proportions like this:
[tex]\frac{x}{50} =\frac{2}{100}[/tex]
^^^you want to find 2% of 50, so 50 is the "whole" and x (what you are looking for) is the part. The reason there is the 100 is because % are always taken out of 100% , and therefore 100 is the "whole". 2 is on top of 100 because it is a "part" of 100
the next step is cross multiplication so you would get:
100x= (50*2) ---> 100x = 100
^^^you then solve this like a normal algebra equation to get x = 1
Hope this helped! Let me know if there is anything else I can do!
can anyone help on these two questions show your work and explain please 5. the table below shows the temperature T(m) of a cup of hot chocolate that is allowed to chill over several minutes.) which expression best fit the data for T(m) ) A. 150(0.85)m B. 150(1.15)m C. 150(0.85)m-1 D. 150(1.15)m ) 7. the function f(x)=3x squared +12x+11 can be written as vertex form as what? and what is vertex form?
Answer:
(1), (3)
Step-by-step explanation:
5. If m starts at 1, a geometric series has the form a₁ (r)ᵐ⁻¹.
If m starts at 0, a geometric series has the form a₀ (r)ᵐ.
Here, m starts at 0. The first term, a₀, is 150. The temperature is decreasing, so we're looking for an r < 1. Therefore, the answer must be (1) 150 (0.85)ᵐ.
7. A quadratic written in vertex form is:
y = a(x - h)² + k
We can find the vertex of the parabola using x = -b/(2a).
x = -12 / (2*3)
x = -2
f(-2) = 3(-2)² + 12(-2) + 11
f(-2) = -1
So the vertex (h, k) is at (-2, -1).
Therefore, the answer must be f(x) = 3(x + 2)² - 1
We can also show this by completing the square.
f(x) = 3x² + 12x + 11
f(x) = 3(x² + 4x) + 11
f(x) = 3(x² + 4x + 4) - 3(4) + 11
f(x) = 3(x + 2)² - 1

Solve for n. n + 1 = 4(n – 8) n = 1 n = 8 n = 11 n = 16
Answer:
The correct option is C) n= 11.
Step-by-step explanation:
Consider the provided equation.
[tex]n+1=4(n-8)[/tex]
Open the parentheses and apply the distributive property as shown:
Distributive property [tex]a(b+c)=ab+ac[/tex]
[tex]n+1=4n-32[/tex]
Now, isolate the variables by adding 32 and subtracting n on both the sides.
[tex]n+1-n+32=4n-32-n+32[/tex]
[tex]33=3n[/tex]
Now divide both the sides by 3.
[tex]\frac{33}{3}=\frac{3n}{3}[/tex]
[tex]11=n[/tex]
Hence the value of n is 11
Thus, the correct option is C) n= 11.

A cube has an edge measuring 7 inches. What is the volume of the cube, in inches³?
Answer:
343 in^3
Step-by-step explanation:
The volume of a cube is found by V = s^3. Here s = 7. So the volume is 7*7*7 = 343 in^3.
Final answer:
The volume of a cube with an edge length of 7 inches is 343 cubic inches.
Explanation:
The volume of a cube is calculated by multiplying the length, width, and height of the cube. Since all sides of a cube are equal, we simply need to cube the length of one side.
In this case, the edge (length, width, and height) of the cube is 7 inches.
The volume of a cube with an edge length of 7 inches can be calculated as follows:
Volume = edge length³Volume = 7³Volume = 7 x 7 x 7 = 343 cubic inchesTherefore, the volume of the cube is 343 cubic inches.
The price of a shirt with a $5 tax. The original shirt price is g dollars.
Select the correct answer.
Question 2 options:
5g
g - 5
g + 5
Final answer:
The price of the shirt after including a $5 tax is represented by the expression 'g + 5', where 'g' is the original price of the shirt.
Explanation:
When calculating the price of an item after tax, you simply add the tax amount to the original price of the item. In this case, the original shirt price is represented by the variable g dollars, and a $5 tax is added to this price. Therefore, the correct answer to the question 'The price of a shirt with a $5 tax. The original shirt price is g dollars.' is g + 5.
What’s the slope between -14,-10 and 12,18
[tex]\bf (\stackrel{x_1}{-14}~,~\stackrel{y_1}{-10})\qquad (\stackrel{x_2}{12}~,~\stackrel{y_2}{18}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{18-(-10)}{12-(-14)}\implies \cfrac{18+10}{12+14}\implies \cfrac{28}{26}\implies \cfrac{14}{13}[/tex]
Answer:
28/26
Step-by-step explanation:
We can find the slope using the equation
y2-y1/x2-x1
We are give two points so lets plug them into the equation above
18-(-10)/12-(-14)
= 18+10/12+14

Solve for t.
-5 − 2t = 3t
First, we have to isolate the t, or keep it by itself, to solve. To do that, we need to move everything with t in it to on side.
-5 - 2t + 2t = 3t + 2t
The -2t and + 2t cross out, leaving us with t on one side, which is exactly what we want!
-5 = 5t
But t isn't alone yet. We need to get rid of its five. To do that, we need to use the same process: use the opposite symbol. In 5t, 5 is being multiplied by t. To get rid of, we need to divide 5. BUT the mega rule in algebra... what you do to one side you must do to the other, or else the equation would not be true anymore, so...
-5/5 = 5t/5
-1 = t
There's your answer! Hope this helps!
Whats is the equation of the following line?
D. Y= - 4/3 x Rise over run
The equation of the line is:
C. [tex]y=\dfrac{-3}{4}x[/tex]
Step-by-step explanation:The line passes through the point (0,0) and (4,-3).
By using the two point formula to find the equation of the line.
i.e. any line passing through two points (a,b) and (c,d) is calculated by using the formula:
[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex]
Here (a,b)=(0,0) and (c,d)=(4,-3)
Hence, the equation of line is calculated as follows:
[tex]y-0=\dfrac{-3-0}{4-0}\times (x-0)\\\\i.e.\\\\y=\dfrac{-3}{4}\times x\\\\i.e.\\\\y=\dfrac{-3}{4}x[/tex]
Hence, the correct answer is: Option: C

B) 4/5
C) 3/5
D) 5/4
E) 4/3
Random answers will be reported!
Answer:
Then tan(x) = 4/3
Step-by-step explanation:
Given that we have a rectangle ABCD, we can affirm the following:
AD = BC = 4
AB = DC = 3
Now, we now that tan = Opposite Side / Adjacent Side
Then the opposite side to the angle x is AB = 4, and the adjacent side to angle x is DC = 3.
Then tan(x) = Opposite Side / Adjacent Side = 4/3 = 1,3333.

3x+1+5x=7+15+7x what is x?
Answer: x=21
Step-by-step explanation:
To solve for x you must first combine you like terms on each side of the equal sign. So you problem will become 8x+1=22+7x. Then get your x on one side and your numbers on the other by taking the one away from the right side and 1 away from 22. Then take away 7 from the left side to cancel it out. Then take 7x away from 8x to leave you with x. making your answer x=21
Answer:
x = 21Step-by-step explanation:
3x + 1 + 5x = 7 + 15 + 7x combine like terms
(3x + 5x) + 1 = (7 + 15) + 7x
8x + 1 = 22 + 7x subtract 1 from both sides
8x = 21 + 7x subtract 7x from both sides
x = 21
4x+24=5x+1 what pus it really need answer
Subtract 4x from both sides
24 = 5x + 1 - 4x
Simplify 5x + 1 - 4x to x + 1
24 = x + 1
Subtract 1 from both sides
24 - 1 = x
Simplify 24 - 1 to 23
23 = x
Switch sides
x = 23
Answer:
Step-by-step explanation:
Subtract 4x from both sides
24 = 5x + 1 - 4x
Simplify 5x + 1 - 4x to x + 1
24 = x + 1
Subtract 1 from both sides
24 - 1 = x
Simplify 24 - 1 to 23
23 = x
Switch sides
x = 23
