the diameter is a circle is 16in. Find it’s circumference in terms of π.
C= ________in
According to the question,
Diameter of circle = 16 inWe are asked to calculate it’s circumference in terms of π.
★ Circumference of circle = 2πr
___________________________________
Let us first calculate the radius of the circle.
→ Diameter = 2 × Radius
→ 16 in = 2r
→ r = 16 in ÷ 2
→ r = 8 in
___________________________________
Substituting values in the formula of circumference,
→ C = 2πr
→ C = (2 × π × 8) in
→ C = 16π in
Therefore, 16π inches is the required answer.
Use the Substitution Method, what is the point of intersection for the following system:
2x + 2y = 18
Y = 2 - 3
Answer:
[tex]2x + 2(x - 3) = 18 \\ 2x + 2x - 6 = 18 \\ 4x = 24 \\ x = 24 \div 4 = 6 \\ y = x - 3 = 6 - 3 = 3[/tex]

Let’s figure out one more adjustment for the butterscotch chip cookies. The butterscotch chip cookie recipe calls for 12 ounces of chips for every 2 cups of flour. How many ounces of chips are needed if 3 cups of flour are added?
Remember to keep your units consistent.
I believe it would 18 ounces of chips for 3 cups of flour. If you take half of 12 ounces then you get 6 ounces per cup of flour. Adding 6 ounces to the 12 would get us the total of the 18 ounces.
Simplify the ratio-
2kg : 3kg : 1.5 kg
Answer:
1.33kg : 2kg : 1kg
Step-by-step explanation:
2kg : 3kg : 1.5 kg
Given data
We have the ratio
2kg : 3kg : 1.5 kg
Let us reduce the ratio further
2/1.5: 3/1.5 : 1.5/1.5
1.33kg : 2kg : 1kg
Hence the simplified ratio is 1.33kg : 2kg : 1kg

A random sample of internet subscribers from the west coast of the United States was asked if they were
satisfied with their internet speeds. A separate random sample of adults from the east coast was asked the same
question. Here are the results:
A market researcher wants to perform a x2 test of homogeneity on these results.
What is the expected count for the cell corresponding to east coast subscibers who
responded "yes"?
You may round your answer to the nearest hundredth.
Answer:
19.2
Step-by-step explanation:
khan
The expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We need to first calculate the expected frequencies for each cell under the assumption that the null hypothesis of homogeneity is true.
The null hypothesis of homogeneity assumes that the proportion of internet subscribers satisfied with their internet speeds is the same on both the east and west coasts of the United States.
To calculate the expected frequencies, we can use the formula:
Expected frequency = (row total x column total) / grand total
For the cell corresponding to east coast subscribers who responded "yes":
Expected frequency = (row total for east coast x column total for "yes") / grand total
= (80 x 48) / 200
= 19.2
Therefore, the expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

There is just enough water in the container to exactly fill the
hemisphere. The container is held so that the point of the cone
is down and the altitude of the cone is exactly vertical. Find the
height of the water in the cone. Round to the nearest tenth.
Answer: hello your question is Vague hence I will provide a general solution. in which you can input your values into and get your answer.
answer = h = 3 ( V / π r^2 )
Step-by-step explanation:
The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .
The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )
∴ h = 3 ( V / π r^2 )

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answer:
V = 3,367.6 cm³
Step-by-step explanation:
Diameter of sphere (D) = 18.6 cm
radius (r) = ½(18.6) = 9.3
π = 3.14
Formula for volume of a sphere = ⁴/3πr³
Plug in the values
V = ⁴/3 × 3.14 × 9.3³
V = ⁴/3 × 3.14 × 804.357
V = (4*3.14*804.357)/3
V = 3,367.57463
V = 3,367.6 cm³ (nearest tenth)

solve 3x by 4 - 2x+5 by 3 = 5 by 2
Answer:
50
Step-by-step explanation:
The given equation is,
→ 3x/4 - (2x + 5)/3 = 5/2
→ 3x × 3 - 4(2x +5)/12 = 5/2
→ 9x - 8x -20/12 = 5/2
→ (x - 20)/12 = 5/2
→ x - 20 / 6 = 5
→ x - 20 = 30
→ x = 20 + 30
→ x = 50
• Hence the value of x is 50 .Answer:
x=50

Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?
Answer:
54 years
Step-by-step explanation:
Given that :
Let :
Ann's age = x
Mary's age = x/2
Donald's age = x/3
x + x/2 + x/3 = 99
Take the L. C. M
(6x + 3x + 2x) / 6 = 99
11x / 6 = 99
11x = 99 * 6
11x = 594
x = 594 / 11
x = 54
Hence, Ann is 54 years

A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing
books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
Answer:
O no, because people in the bookstore are interested in purchasing books, so they do not represent all shoppers in the mall
Step-by-step explanation:
In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.
Doing this, would help to give an accurate representation of both group in the survey.

Closest to the shaded area
Answer:
B) 30.9
Step-by-step explanation:
So, because the radius is 6, we know the diameter is 12, meaning we know each side is 12, so the total area of the square is 144.
To find the area of a square we should use pi(r) ^2 which is pi(6) ^2 which is 113.09. to find the area of the shaded are we would subtract these. 144- 113.09 this gets us 30.91, this is closest to B) 30.9
