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
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.

Brittany needed new tires for her truck. She went to the auto shop and bought 4 tires on sale for $85.95 each. The salesman told her that she saved a total of $96.16. If Brittany saved the same amount on each tire, what was the original price of each tire?
Answer:
Answer: $109.99
Step-by-step explanation:
The total amount saved, $96.16, should be divided by the number of tires, 4. The answer is $24.04. Add $24.04 to the price of a single tire, $85.95, and the answer is $109.99, the original price of one tire.

5 768
a
Arithmetic sequence; common difference is 96
b
Arithmetic sequence; common difference is −144
c
Geometric sequence; common ratio is 3
d
Geometric sequence; common ratio is −2
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

Determine the slope and y-intercept of a line that passes through the points (-2, 12) and (4, -15).
Step-by-step explanation:
y²-y¹/x²-x¹
(-15)-(12)/4-(-2)
-3/6
=-0.5
y=mx+b
12=-0.5(-2)+b
12=1+b
12-1=b
11=b
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

for the function of F defined by f (x) = x + 8. what is the value of x when f (x) = 10
Answer:
x = 2
Step-by-step explanation:
f(x) = x + 8
f(x) = 10
10 = x + 8
minus 8 from the both sides
10 - 8 = x

Answer:
9 avocados
Step-by-step explanation:$21.00 - $2.50 = $18.50
3 × $5.00 = $15.00
$18.50 - $15.00 = $3.50
$15 = 3 bags of avocados = 3 bags × 3 avocados = 9 avocados

Step-by-step explanation:
Given: The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch .
The height of the model of the statue = [tex]\dfrac{1}{100}\times\text{ (Height of actual model)}[/tex]

The table shows a relationship between x and y. What is the constant of proportionality, k, which relates the variable y to the variable x?
Answer:
F. [tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Constant of proportionality, k, = [tex] \frac{y}{x} [/tex]
The ratio of each given of values on the table will give you the same value, which represents k.
Thus, using the pair, (2, 1.5), k can be calculated as follows:
[tex] k = \frac{y}{x} = \frac{1.5}{2} [/tex]
Multiply the numerator band denominator by 10 to eliminate the decimal point.
[tex] = \frac{1.5*10}{2*10} = \frac{15}{20} [/tex]
Simplify
[tex] k = \frac{3}{4} [/tex]

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.
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
