Step-by-step explanation:
Cylinder A:r = 3 cm
Volume = 27π cm³
[tex]\sf \boxed{\text{Volume of cylinder=$\pi r^2h$}}[/tex]
[tex]\sf \pi*3*3*h = 27 \pi\\[/tex]
[tex]h = \dfrac{27 \pi}{\pi * 3 * 3}\\\\ \boxed{\bf h = 3 \ cm}[/tex]
Cylinder B:[tex]\sf \r_A : r_B = 3 : 9[/tex][tex]\sf r_A : r_B = 3 : 9[/tex]

[tex]\sf h_A : h_B = 1 : 3\\[/tex]
[tex]\sf \dfrac{3}{h_B}=\dfrac{1}{3}\\\\ cross \ multiply,\\\\ 3*3 = 1*h_B\\\\ h_B = 9 \ cm[/tex]
Volume of cylinder B = π * 9 * 9 * 9

How do I find a point on the line whose equation is 3x-8y=54
Answers
An equation is formed of two equal expressions. A point that will lie on the line 3x-8y=54 is (5,-4.875).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To find a point on the line 3x-8y=54, take any random value of x and substitute for the equation, and solve the equation for y. Now, as you have the value of x and y, you have the coordinate of the point.
Let the value of x be 5.
3x-8y=54
3(5)-8y =54
15-8y = 54
-8y = 54 - 15
-8y = 39
y = -4.875
Hence, a point that will lie on the line 3x-8y=54 is (5,-4.875).

Surface area of a new cereal box with dimensions of
L=8 in
W=1.75in
H=12.125in
Answers
Answer:
264.4375
Step-by-step explanation:
Surface area of a box = 2(lw + lh + wh)
L = 8 , W = 1.75 and H = 12.125
==> plug in values
SA = 2((8)(1.75) + (8)(12.125) + (1.75)(12.125))
==> multiply values that are inside parenthesis together
SA = 2(14 + 97 + 21.21875)
==> add values inside of parenthesis
SA = 2(132.21875)
==> multiply 2 and 132.21875
SA = 264.4375in²

What is the inverse of the function f(x)=-1/2(x+3)?
Answers
The inverse of the function is : [tex]\frac{-1-6x}{2x}[/tex]
What is an inverse function?An inverse function is a function that serves as an eliminator of a given function.
A function that has an inverse is called invertible function and it is denoted as [tex]f^{-1}[/tex].
Analysis:
let y = [tex]\frac{-1}{2(x+3)}[/tex]
so that,
2y(x+3) = -1
2yx + 6y = -1
2yx = -1 -6
x = [tex]\frac{-1 - 6y}{2y}[/tex]
replacing y with x
[tex]f^{-1}[/tex](x) = [tex]\frac{-1-6x}{2x}[/tex]
In conclusion, the inverse of the function is : [tex]\frac{-1-6x}{2x}[/tex]

How many buses do you need for 750 people if each bus holds 150 people?
Answers
Answer:
5 buses
Step-by-step explanation:
As, 150 people are hold by= 1 bus
therefore,
750 people are hold by=1/150x750 buses
=5buses
Answer:
5 buses
Step-by-step explanation:
Given:
Each bus holds 150 peopleTo find:
Buses for 750 peopleSince each bus or a single bus can hold 150 people, we can represent the sentence in math expression as:
[tex]\displaystyle\large{1B = 150P}[/tex]
B stands for Bus and P stands for People. Therefore we have the equation of:
[tex]\displaystyle \large{B=150P}[/tex]
Next is to find how many buses can hold 750 people so we will have to multiply both sides by 5 since 150*5 = 750.
[tex]\displaystyle \large{5B=150*5}\\\displaystyle \large{5B=750}[/tex]
If one bus can hold 150 people then 5 buses can hold 750 people. Hence the solution is 5 buses.

"Given m = -2/5 and b = -7, write the equation of the line containing these points"
can someone help?
Answers
Answer: y = (-2/5)x - 7
This is the same as writing [tex]y = -\frac{2}{5}x-7[/tex]
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7

Using the Empirical Rule, it is found that 16% of the data points are greater than 11.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, the mean is of 9.8 and the standard deviation is of 1.8.
11 is one standard deviation above the mean. Considering the symmetry of the normal distribution, 32%(more than one standard deviation above the mean)/2 = 16% of the data points are greater than 11.
