The volume of a cone is computed using the formula volume = 1/3 pi r^2 h
for this cone r = 5 m h = 12 m
Plug in the values : volume = 1/3 * 3.14 * 5^2 * 12 = 314 m^3
Answer: 314 m^3
Step-by-step explanation:
The volume of a cone is [tex]\pi *r^2*h/3[/tex]
[tex]\pi = (3.14) *r^2 = (5^2)* h/3 = (12/3)[/tex]
Step 1. Simplify the expression. [tex]3.14 * 25 * 12/3[/tex]
Step 2. Simplify the expression again. [tex]3.14 *25*4[/tex]
Step 3. Multiply 25 and 4. [tex]3.14 * 100[/tex]
Step 4. Finish simplifying. [tex]314 .m^3[/tex]

You have a bag of marbles with 630 marbles in it: 110 red, 230 green, and 290 blue. You pull out 1 marble, record the color, and replace it.
After you do this 100 times, the table shows the number of times each color was drawn:
Red Green Blue Total
21 35 44 100
Give exact, reduced answers.
a) What is the theoretical probability of drawing a blue?
b) What is the experimental probability of drawing a blue?
Answers
Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

Which expression represents the sum of 2/3m - 1 1/6 and 5/6m - 1 1/3?
HOW DO I DO THIS??????
Answers
Answer:
-m+15/6
2/3m-5/3m-5/2
Answer: 1 5/6m - 2 1/2
Step-by-step explanation:
(2/3m - 1 1/6) + (5/6m - 1 1/3)
2/3m X 2 = 4/6m
4/6m + 5/6m = 11/6m=1 5/6m
-1 1/3 X 2 = -1 2/6
-1 2/6 - 1 1/6 = -2 1/2

x being zinc, what we need to find
Next we can cross multiply

Write the equations of each line in slope-intercept form. (y=mx+b)
Answers
The slope-intercept form of the equation of a line is given by:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
To find the equation of a line in slope-intercept form, we need to determine the values of m and b.
Here are two examples:
The line passes through the points (2, 4) and (4, 8).
To find the slope, we use the formula:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) = (2, 4) and (x2, y2) = (4, 8)
m = (8 - 4)/(4 - 2) = 2
To find the y-intercept, we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
where (x1, y1) is one of the points on the line, for example, (2, 4).
y - 4 = 2(x - 2)
y - 4 = 2x - 4
y = 2x + 0
Therefore, the equation of the line in slope-intercept form is y = 2x.
The line passes through the point (3, 7) and has a slope of -3.
We can use the point-slope form of the equation of a line to find the equation in slope-intercept form.
y - y1 = m(x - x1)
where (x1, y1) is the given point, (3, 7), and m is the slope, which is -3.
y - 7 = -3(x - 3)
y - 7 = -3x + 9
y = -3x + 16
Therefore, the equation of the line in slope-intercept form is y = -3x + 16
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12
y = -2x + 19

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answers
Answer:
Step-by-step explanation:
To make the race close, the length of the race should be 450 meters.
Here's the reasoning behind the answer:
Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.
The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.
During this time, Henri would have walked a distance of 1 x 18 = 18 meters.
So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).
To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.
Let's call the total distance of the race "d."
So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).
We can set up an equation to solve for d:
d/1 = (d + 27)/2.5
Solving for d, we get:
d = 450
So, the race should be 450 meters long for Henri to win in a close race.

PLEASE HELP ME ASAP!! Charlie is practicing the long jump. His first jump is a distance of 16[tex]\frac{5}{6}[/tex] feet. His second jump is a distance of 18 [tex]\frac{2}{3}[/tex] feet. How much longer is Charlie's second jump? Please explain!!!
Answers
Answer:
[tex]2 \frac{1}{6} [/tex]
Step-by-step explanation:
So we have
[tex]16 \frac{5}{6} \: and \: 18 \frac{2}{3} [/tex]
If you have the same denominator for each fraction, you'd be able to subtract the numerators like regular subtraction
Seeing the 2/3, if we multiply each number by 2, you get
[tex]18 \frac{4}{6} [/tex]
Now you have 5/6 and 4/6. Since they both have 6 at the bottom, you can subtract 5 and 4.
5-4=1
Now you have 1/6.
Then you can just subtract the 18 and 16 like normal giving you 2.
After we combine our numbers, we get 2 1/6. Hope this helps
When you do this you end up with 2. Hope this helped
