Jackson buys a grape snow cone on a hot day. By the time he eats all the "snow" off the top, the paper cone is filled with 27 pi cm^3 cubed of melted purple liquid. The radius of the cone is 3 cm.
What is the height of the cone?
Either enter an exact answer in terms of pi or use 3.14 for pi.
Answer:
9 cm
Step-by-step explanation:
Use the cone volume formula, V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Plug in the volume and radius, and solve for h, the height:
V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
27[tex]\pi[/tex] = [tex]\pi[/tex](3²)[tex]\frac{h}{3}[/tex]
27[tex]\pi \\[/tex] = 9[tex]\pi[/tex][tex]\frac{h}{3}[/tex]
3 = [tex]\frac{h}{3}[/tex]
9 = h
So, the height of the cone is 9 cm

Lin solved the equation 8( x - 3 ) + 7 = 2x( 4 - 17 ) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's solution:
8( x - 3 ) + 7 = 2x( 4 - 17 )
8( x - 3 ) + 7 = 2x(13 )
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x

Answer:
1. Jesús Colón is trying to debate weather or not to help the woman and her two young children. He thought it was a good idea because she was carrying a suitcase and a baby but at the same time he wasn't so sure because he was worried about what the woman would think and if she was racist or prejudice. He even was afraid that the woman would try talk to him in mean ways or to discriminate him just because he was both African and Puerto Rican.
2. Colón had his reputation at stake in this decision due to what the woman would do exactly. Since he didn't help the woman he regretted it and believed he should have helped her even if it would have costed him.
3. I believe he wrote this story to explain that simple actions can lead to a huge change in the future. For example if you see some one who is mean and they need help and you help them then that one mean person can become a really nice person in return just from your actions.
4. I would have helped the woman even though the circumstances because no matter my skin color, reputations, or the way i look i would help anyone because they may not know but deep down i am a good person. And you should not judge a book by its cover.
5. I would not care what others think even though i might fell that its not my place to do something i would do it anyway because nothing can change me. Words may be mean but they can not hurt me.
Step-by-step explanation:
I read everything and answered based on my thoughts and feelings and the text. Have a nice day :)

Calculate the area of the shaded region between the regular polygons. Round to the nearest hundredth.
Answer:
I hope I'll help you with this but I am not sure of it all...
The area of the shaded region is 46,77
Step-by-step explanation:
To determine the area of the shaded hexagon, we must first calculate te area of the whole shaded hexagon and minus that by the white little hexagon.
The formula to calculate the area of a hexagon is (3√3 s2)/ 2
(where s = one side of the hexagon)
if one side a the little white hexagon equals 6 ft;
3√3 6ft.2/2 = 18√3/2 = 9√3
now for the bigger hexagon where one side is 12 ft;
3√3 12 ft.2/2 = 72√3/2 = 36√3
now the area of the bigger one minus the area of the smaller one;
36√3 - 9√3 = 46,77

Step-by-step explanation:
A football team scored 80% of a total of 500 points in the first 11 games of the season. Fill in the model to show 80% of 500
The model that shows the statement of 80% of 500 will be equal to 400 points.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the given data in the question,
Total number of points in the game = 500 points
Total percentage of score done by the team = 80% of total points
Then, the points will be,
= (500 × 80)/100
= 40,000/100
= 400 points.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.
A(n)=6+(n-1)(1/5)
Answer: a’(n)=1/5
Step-by-step explanation:
The first term is 6, the fourth term is 6.6, and the tenth term is 7.8 in the arithmetic sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The given rule for the arithmetic sequence is:
A(n) = 6 + (n - 1)(1/5)
To find the first term, substitute n = 1 in the formula:
A(1) = 6 + (1 - 1)(1/5)
A(1) = 6 + 0
A(1) = 6
Therefore, the first term of the arithmetic sequence is 6.
To find the fourth term, substitute n = 4 in the formula:
A(4) = 6 + (4 - 1)(1/5)
A(4) = 6 + 3/5
A(4) = 6.6
Therefore, the fourth term of the arithmetic sequence is 6.6.
To find the tenth term, substitute n = 10 in the formula:
A(10) = 6 + (10 - 1)(1/5)
A(10) = 6 + 9/5
A(10) = 7.8
Therefore, the tenth term of the arithmetic sequence is 7.8.

Hello! Can someone please help? I would really appreciate it! Thx! :)
Answer:
55
Step-by-step explanation:
a line is 180° so you subtract 180 by 125 and you get 55
Answer: Either 45 or 55 degrees
Explanation: The angle of number 5 is acute or in other words small therefore it cannot be 145 degrees or 125 degrees. Seeing how small #5 is I would go for 55 degrees. If you do 180 (the measure of the line) - 125 = 55

Using the formula for the area of a triangle, area=1/2*base*height , write an expression for the area of ΔABC. This time, base your answer on the work you did in part E. Show your work. The graph so far is provided.
Did you ever get the answer?
I did mine but i don’t know if it’s correct (I haven’t submitted it yet)
Area = 1/2 * base * height
Base= b = 20
Height = BD = 9.05
Area = 1/2 * 20 * 9.05
Area = 90.5 units squared
The expression for the area of ΔABC will be A = 1/2 x CA x BD, and the area is 90.5 square units.
What is the area of the triangle?The area of the triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the triangle.
Then the expression for the area of ΔABC will be
A = 1/2 x CA x BD
A = 1/2 x 20 x 9.05
A = 90.5 square units
