Answer:
The cylinder's radius is 2 inches and it’s height is 3 inches.Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in
i have a test tomorrow and i forgot this but how do you do something like this:
-(-14⅞)-15+(-⅚)-14⅞
Answer:
-15 5/6
Step-by-step explanation:
Combine the given terms (through addition and subtraction).
14 7/8 - 15 - 5/6 - 14 7/8
Identify the LCD: It is 24
Therefore we have:
14 21/24 - 15 - 20/24 - 14 21/24
Combining the whole numbers, we get
14 - 15 - 14, or -15
and combining the fractions, we get
21 - 20 - 21
----------------- = -20/24
24
and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6

Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus. If
he arrives at the bus stop three consecutive days at 7:30, what is the approximate probability that he catches the bus all
three days?
Answer: 0.614
Step-by-step explanation:
First find the probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am, the probability he will catch the bus is:
= (P | Day 1) * (P | Day 2) * (P | Day 3)
= 0.85 * 0.85 * 0.85
= 0.614
The approximate probability that he catches the bus all three days is 0.614.
Given that,
Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus.
If he arrives at the bus stop three consecutive days at 7:30,
We have to determine,
What is the approximate probability that he catches the bus all three days.
According to the question,
The probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus,
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am,
Then, the probability he will catch the bus is:
= (P | Day 1) × (P | Day 2) × (P | Day 3)
= 0.85 × 0.85 × 0.85
= 0.614
Hence, The approximate probability that he catches the bus all three days is 0.614.

Solve for n.
n+ 1 = 4(n-8)
Answer:
11
Step-by-step explanation:
n+1=4(n-8)
n+1=4n-32
4n-n-32=1
3n-32=1
3n=1+32
3n=33
n=33/3
n=11
Answer:
n = 11
Step-by-step explanation:
The equation is n+1=4(n-8). This is much easier to solve after expanding, which makes n+1=4n-32. Then, add 33 to each side to make n+33=4n. Next, take away n from each side, to get 33=3n. You want to find n, so divide each side by 3. This means you end up with 11=n.

In the triangle below, which of the following best describes Xy?
Y
40°
40°
A. Angle bisector
B. Median
C. Altitude
O
D. Perpendicular bisector
Answer:
option A is correct answer of this qn
The word which best describes XV is Angle Bisector.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given is a triangle XYZ.
Here a line segment is drawn from the vertex X to the opposite side YZ.
Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.
Here, it is not given that, YV = ZV, so it is not median.
Altitude is the perpendicular line joining the vertex to the opposite side.
Here, it is not given the line is perpendicular. so it is not altitude.
Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.
Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.
So the line is angle bisector.
Hence the correct option is Angel Bisector.

Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)
__
This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form
x +2y = 3 . . . . . . . . . standard form

Answer:
7 buffalos and 3 ducks
Step-by-step explanation:
create a system of equations:
4 y + 2 x = 34
y + x = 10
* y is for buffaos and x is for ducks
solve the equation:
y=10-x
4(10-x)+2x=34
x=3
y=10-3
y=7
7 buffalos and 3 ducks
Four people—Rob, Sonja, Jack, and Ang—enter their names into a drawing. The winner receives either a t-shirt or a mug, and which prize they receive is randomly selected.
What is the probability that either Ang wins and is given a mug, or Jack wins (and is given either prize)? Give the answer as a percent.
Answer: 50%
Step-by-step explanation: Good luck! :D
Answer:
The probability is 37.5%
Step-by-step explanation:
There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.
So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.
