Answers
Answer:
254.5 ft^3
Step-by-step explanation:
The volume of a cylinder is the area of the base times its height. To find the area of the base, since it is a circle, you would use the area formula of a circle([tex]\pi r^{2}[/tex] where r is the radius). So, the circle would have an area of 81 π. Now, multiplying this by the height, you get the volume. Since the height is just 1, the volume would be 81π which is 254.469004941. This rounded to the nearest tenth is 254.5.
Step-by-Step Explanation:
Height (h) = 1 ft
Radius (r) = 9 ft
Pi (π) = 3.14
Volume of Cylinder = πr^2h
Therefore,
=> πr^2h
= π * r * r * h
= 3.14 * 9 * 9 * 1
= 28.26 * 9 * 1
= 254.34 * 1
= 254.34
Rounding off to nearest 10th = 254.3
Volume of Cylinder = 254.3 ft^3

In the figure, ∆ABD ≅ ∆CBD by Angle-Side-Angle (ASA). Which segments are congruent by CPCTC?
Answers
Answer: AB ≅ CB
Step-by-step explanation:
In the given figure, we have ∆ABD ≅ ∆CBD
The CPCTC property of congruent triangles says that if two triangles are congruent then their corresponding parts ( angles and segments ) are congruent.
Since we have given that ∆ABD ≅ ∆CBD.
Therefore, the corresponding segments are congruent.
As segment AB is corresponding to segment CB. [First two letters]
Therefore, segment AB is congruent to segment CB.
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).

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.

Write 12x+4y=-36 in slope intercept form.
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]
Slope intercept form looks like so:-
y=mx+b
Right now the line's equation is written in standard form, ax+by=c.
First, subtract 12x on both sides:-
4y=-36-12x
Now divide by 4 on both sides:-
y=-9-3x
On further simplification,
switch -9 and -3x places (it's not mandatory)
y=-3x-9
That's our equation in slope intercept form.

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

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.

"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
