This is because when the top line is facing C in this case and the bottom line is facing B it would be a 90° angle. Due to it being less than 90°, and it can not be a decimal your only choice would be 45°.
The only reason it is not 180° is because when 180° is shown it will go from A to B and show a straight line.
I hope this helped!

A manufacturing plant has 60
supervisors. If 27 of the supervisors are
men, then
O 45% are women
55% are men
55% are women
O 75% are men
O 75% are women
Answers
Answer:
55% are women
Step-by-step explanation:
27÷60= 0.45
0.45x100=45
100-45=55
45% men
55% women
There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.
The number of women = 60 – 27 = 33
The percent of women = (33/60)×100
= 0.55×100
= 55%
Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

2. A set of barbells consist of red and blue discs. Discs with the same color have the same mass. Using a balance,
Lia found that 7 blue discs balance 1 red disc and a 5kg mass, while 2 blue discs and a red disc balance a 4kg
mass. Find the masses of the red and blue discs. (2kg, 1kg)
Answers
Let r be the mass of a red disc and b the mass of a blue disc.
7 blues have the same mass as 1 red along with a 5 kg mass, so
7b = r + 5
7b - r = 5
2 blues and 1 red have the same mass as a 4 kg mass, so
2b + r = 4
Solve for b and r . Notice that adding the equations together eliminates r :
(7b - r) + (2b + r) = 5 + 4
9b = 9
b = 1
Then
7 • 1 - r = 5
r = 7 - 5
r = 2
So each red disc has a mass of 2 kg, and each blue disc has a mass of 1 kg.
what is the value of q in the equation 4/5q = 32
Answers
Answer:
40
Step-by-step explanation:
4/5 * q = 32
First you divide 4/5 by itself so you can eliminate it from the equation and then you have to divide 32 by 4/5 n when you do that you get 40. So q = 40.
A roller coaster at an amusement park rises to a height of 196 feet above the ground. So far, it has risen 36% of this height. To estimate the height the roller coaster has risen so far, Jake did the following.
1. Rounded 36% to 40%
2. Rounded 196 to 200
3. 10% of 200 is 20
4. 20 (4) = 80
5. 36% of 196 is about 80
However, Jake’s estimate was too high by almost 10 feet. Why was his estimate off by so much?
He made a computation error.
He rounded the percent up to 40% and the number up to 200.
He made a rounding error, and should have rounded 196 down to 100.
He should have rounded the percent down to 30% and the number down to 190.

What is 1872.072 rounded to the nearest hundredth?
Answers
Answer:
1872.07
Step-by-step explanation:
The hundredth place is the second digit after the decimal (.).
The 1872 will always be the same since it is hundredth and not something else like tens or hundreds.
1872....
So since the hundredth place is the second digit after the decimal, you can find that the second digit is 7.
4 or less don't round up, 5 or more round up
Since the next digit is 2, it is 4 or less, so don't round up, so you cut off the 2, hence the 1872.07
EDIT: Aha I need my sense of humor back... brb
Answer: 1872.07
Step-by-step explanation: 7 is in hundredth place so we take the number that comes after it and round up or down since it 2 we round down to 0 then add it to 7.
7+0= 7 so 7 stays the same (because numbers from 1-4 round to zero and numbers from 5/9 round to 1)

Determine the slope and y-intercept of a line that passes through the points (-2, 12) and (4, -15).

The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c.
The slope can be calculated.
Slope = (d - b) / )(c - a)
Where (a, b) and (c, d) are the two points on the line.
The line passes through (-2, 12) and (4, -15)
This means,
Slope = (-15 - 12) / (4 + 2) = -27 / 6
m = -27/6
The line passes through the point (-2, 12).
12 = -27/6 x -2 + c
12 = 9 + c
c = 12 - 9
c = 3
Thus,
The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6
The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3

Answers
Answer:
d Geometric sequence; common ratio is −2
Step-by-step explanation:
Identifying Sequences
There are two possible types of sequences to choose from, Arithmetic and Geometric.
The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term. This number is called the common difference.
In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
The given sequence is:
48, -96, 192, -384, 768,....
To identify the type of sequence, we could try subtracting the second term from the first, the third from the second, etc. If those differences were constant, it would be an arithmetic sequence.
In this case, it's not necessary because the sign of the terms is alternating. It can only be possible with geometric sequences with a negative common ratio.
Dividing the second by the first term:
r = -96 / 48 = -2
Dividing the third by the second term:
r = 192 / -96 = -2
The rest of the divisions of successive terms lead to the same common ratio, thus, the answer is:
d Geometric sequence; common ratio is −2
A cylindrical can, open at the top, is to hold 200 cm3 of liquid. Find the height and radius that minimizes the amount of material needed to manufacture the can.
Answers
Answer:
h = 5.42
r = 5.42
Step-by-step explanation:
Find h with respect to r:
V = πr²h = 500
h = 500/πr²
Plug this into the surface area equation:
SA = πr² + 2πrh
= πr² + 2πr(500/πr²)
= πr² + 1000/r
Differentiate and set to 0, solve for r:
dSA/dr = 2πr - 1000/r² = 0
2πr = 1000/r²
r³ = 500/π
r = (500/π)^1/3
≈ 5.42 cm
find h:
h = 500/πr²
= 500/[π(5.42)²]
= 5.42cm
