Answer:
The correct answer is [tex]108\pi (yd^3)[/tex].
Step-by-step explanation:
The formula to find a volume of a cone is [tex]\pi r^2*\frac{h}{3}[/tex], where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height of the cone. By substituting the values in, you'll get that the volume of the cone is equivalent to [tex]\pi*6^2*\frac{9}{3}[/tex] = [tex]36\pi * 3[/tex] = [tex]108\pi (yd^3)[/tex], so that is the answer.
Answer:
108 cu. yd.
Step-by-step explanation:
V = [tex]\frac{\pi r^{2} h}{3}[/tex] = [tex]\frac{ \pi 6^{2} *9}{3}[/tex] = [tex]\frac{36(9)\pi }{3}[/tex] =[tex]\frac{ 324\pi }{3}[/tex] = 108 cu. yd.
Who is my favorite person ever?
The answer would obviously be :
me.According to a medical study, 15% of people will experience an adverse side effect
within one hour after taking a particular experimented drug. Suppose you survey 12
people who participated in the study. What is the probability at most 2 people will
have adverse side effect?
A)O 0.594
B)0.646
C)0.736
D)0.264
Answer:
c
Step-by-step explanation: trust me
The probability that the people that would have adverse effect are at most 2 is 0.736
What is probability?This is the theory that is used in statistics to explain the chances of an event occuring.
To solve for the probability of at most 2, we solve for 1- P(1) + P(2)
= 1/12 + 2/12
= 1 - 0.083+0.167
= 0.73
Therefore the probability that the most people with adverse effect is 2 is 0.736. Option c is correct.

How to calculate a common fraction
To find a common denominator, multiply each part of a fraction by the denominator of the other fraction. For example, to find a common denominator for 1/3 + 2/5, multiply the 1 and 3 by 5 and multiply the 2 and 5 by 3. You should get 5/15 + 6/15. Then you can calculate the fractions.

What equation do I write for a line that has a y intercept of 2 and is perpendicular to y=2/3x+4?
Answer:
y = -3/2x + 2
Step-by-step explanation:
The equation has the format y = mx + b where m is the slope and b is the y-intercept.
The question gives you the y-intercept, so b = 2.
As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.
The slope of the line given in the question is 2/3. The opposite reciprocal of 2/3 is - 3/2.
The equation for the line is y = -3/2x + 2
Where do f(x) and the line y=1 intersect?

The number 26411 is completely divisible by
Answer:
7, you can just your calculator to test it out.
Answer:
Step-by-step explanation:
Where to start?
It isn't 2 and it isn't 3. You tell it's not 2 because it is an odd number.
It isn't 3 because the digits (26411 = 2 + 6 + 4 + 1 + 1) add up to 14 which is not divisible by 3, so the whole number is not divisible by 3.
It is not divisible by 5 because numbers divisible by 5 end either in 0 (which would make it even and divisible by 2) or 5. This one doesn't end in 5.
The very first number you can try is 7. That works. 3773 is the result.
The next prime to try is 11. I have a feeling that will work as well. Let's try it. It works as well. It's the symmetry of 3773 that made me look at eleven. There is a very complicated rule having to do with the odd and even places subtracted that tells you whether a number is divisible by 11 or not.
343 is the resulting number. I think that is 7^3 which is correct. So here's your answer
7 * 7 *7 * 7 * 11 is the answer. It's worthwhile to know how to do this. Factoring large numbers is one of the cornerstones of mathematics. Computers love this kind of thing.

Step-by-step explanation:
i am smart
Answer:
146 mm²
Step-by-step explanation:
First, let's start with the formula for the surface area of a rectangular prism.
A = 2(wl + hl + hw)
Plug in everything that you know.
A = 2[(4 · 5) + (7 · 5) + (7 · 4)]
Simply the equation.
A = 2(20 + 35 + 28)
A = 2(73)
A = 146

Answer:
500
Step-by-step explanation:
i need help big time look at photo
Answer:
The answer is A.
Step-by-step explanation:
The only reason why it is A is because area is just (l x w) or length times width. The length is 9cm and the width is 8cm. If you multiply that, the answer would be 72cm.
Answer:
B- 59 cm 2
Step-by-step explanation:
rec 1 = 8 x 4 = 32
rec 2 = 3 x 7 = 21
rec 3 = 2 x 3 = 6
area of fig = rec 1 + rec 2+ rec 3 = 32+ 21+ 6 = 59 cm2

Find the perimeter of the figure to the nearest hundredth.
Answer:
61.68cm
Step-by-step explanation:
Perimeter of the semicircle = 2πr
r is the radius = 12/2 = 6cm
Perimeter of the semi circle = 2(3.14)(6)
Perimeter of the semi circle = 37.68cm
Adding the remaining sides of the polygon
Perimeter of the figure = 37.68+ 10 + 6 + 8
Perimeter of the figure = 61.68cm
Hence the perimeter of the figure is 61.68cm

Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Step-by-step explanation:
180° = m∠A + m∠B + m∠C
180° = 85° + 53° + m∠C
180° = 138° + m∠C
m∠C = 180° - 138°
= 42°
