Answer:
A.
2 x 2 = 4 so 4 is the diameter because the diameter is double the radius
diameter x pi = circumference
4 x pi = 3pi or 12.56

Which part of this box plot includes about 50% of the data?
A.
There is not enough information to tell.
B.
The box, from 44 to 52
C.
The lower whisker, from 34 to 44
D.
The upper whisker, from 52 to 59
Answers
Answer:
B
Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.
The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.
Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

A builder bought 5 houses for $2500000 each. He sold $3 of the houses at a profit of 30% and rest of the houses at a loss of 40% . Find his overall profit or loss percent
Answers
Answer:
Step-by-step explanation:
2,500,000 * .3 = 750,000
A) 3* 750,000 = 2,250,000
2,500,000*.4 = 1,000,000
B) 2*1,000,000 = 2,000,000
A-B = profit
profit was 250,000
2,500,000 * 5 = 12,500,000 ( total costs )
12,750,00 ( total sales)
what percent is 250,000 of 12,500,000 ?
250,000 / 12,500,00 = 0.02
this is 2% profit :/ not so good
Susan saw birds and mice eating seeds on the ground. She counted 14 heads and 40 legs in total. How many birds and mice are on the ground?
Answers
Answer:
8 birds and 6 mice
Step-by-step explanation:
Given:
Number of heads = 14
Number of legs = 40
Required
How many birds and mice are on the ground?
Let M represents Mice and B represents Birds
Birds and Mice have 1 head each;
So;
\(B + M = 14\)
Birds have 2 legs; Mice have 4 legs
So;
\(2B + 4M = 40\)
At this point, we have two equations;
Make B the subject of formula in the first equation
\(B + M = 14\) becomes
\(B = 14 - M\)
Substitute 14 - M for B in the second equation
\(2(14 - M) + 4M = 40\)
Open bracket
\(28 - 2M + 4M = 40\)
\(28 + 2M = 40\)
Subtract 28 from both sides
\(28 - 28 + 2M = 40 - 28\)
\(2M = 40 - 28\)
\(2M = 12\)
Divide both sides by 2
\(\frac{2M}{2} = \frac{12}{2}\)
\(M = 6\)
Recall that \(B = 14 - M\)
So;
\(B = 14 - 6\)
\(B = 8\)
Hence, there are 8 birds and 6 mice
A great white shark swims 22 feet below sea level.
If the shark is 67.7 feet from the sailboat, what is the angle of
denression of the boat to the shark
Answers
Answer:
x = 18 degrees
Step-by-step explanation:
Use tan to find the value of x
tan x = 22/67.7 Simplify
tan x = 0.3298 Take the negative of tan to find x
tan^-1 x = 18
The required angle of depression of the boat to the shark is 18.96°.
What are trig ratios?If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
Applying trig ratios, to determine the angle of depression.
Sin x = 22 / 67.7
x = sin ⁻¹[22/67.7]
x = 18.96°
Thus, the required angle of depression of the boat to the shark is 18.96°.

PLEASE HELP ASAP: On a snowy day 85% of the students of Wilson high school were present. If 572 of the students were present, how many students were enrolled at the school?

Do 572 x 100 first to get 57,200.
Then divide 57,200 by 85 to get around 672 students.
However, I haven't done these kinds of questions in a long time, therefore I could be wrong.
On a snowy day 85% of the students of Wilson high school were present., There were 672 students enrolled at Wilson high school.
To find out how many students were enrolled at Wilson high school, we can use the information given in the question. We are told that 85% of the students were present on a snowy day, and that 572 students were present. To find the total number of students enrolled, we can set up a proportion: Present students / Total students = Percentage present / 100 Let's plug in the values we know: 572 / Total students = 85 / 100 To solve for the total number of students, we can cross-multiply and solve for Total students: 572 * 100 = Total students * 85 57200 = Total students * 85 Dividing both sides by 85: 57200 / 85 = Total students Total students = 672 Therefore, there were 672 students enrolled at Wilson high school.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Find the value of c that will make the following two expressions equivalent to 4!!
The answer is 4, Our teacher gave us the answer but I need the work to show how she got it.
2a+10b-8-2(4a-6) and -6a+10b+c
Answers
Answer:
see below
Step-by-step explanation:
We are given 2 equations:
\(2a+10b-8-2(4a-6)\\-6a+10b+c\)
We are told to find c to make them equivalent, so we can make them equal to each other:
2a+10b-8-2(4a-6)=-6a+10b+c
To find c, we have to isolate it, here are the steps:
2a+10b-8-2(4a-6)=-6a+10b+c
subtract 10b from both sides
2a-8-2(4a-6)=-6a+c
rearrange left side
2a-2(4a-6)-8=-6a+c
distribute the positive 2 to the terms in parenthesis
2a-(8a-12)-8=-6a+c
distribute -1 to the terms in parenthesis
2a-8a+12-8=-6a+c
simplify
-6a+4=-6a+c
add -6a to both sides
4=c
