The first painter can finish a paint job in 2 hours. The second painter can finish the same job in 8 hours. How long would it take them to finish the job if they were working together?
If two painters who can individually finish a painting job in 2 hours and 8 hours respectively work together, they will be able to finish the job in 1.6 hours.
Explanation:The question is about determining how fast two painters can finish a paint job if they work together, given their individual working speeds. This is related to the field of mathematics and specifically to the concept of rates. The first painter can finish the job in 2 hours, so, his rate of working is 1/2 of the job per hour. The second painter can finish the job in 8 hours, so his rate of working is 1/8 of the job per hour. When they work together, their rates are added together. So, the combined rate of both painters is 1/2 + 1/8 = 5/8 of the job per hour. To find out how long it would take them to finish the job together, we take the reciprocal of this, which gives us 8/5 or 1.6 hours.

Working together, the two painters would take approximately 1.6 hours or 1 hour and 36 minutes to finish the job.
Explanation:To find how long it would take the two painters to finish the job together, we can use the concept of work rates. The first painter can finish the job in 2 hours, so they have a work rate of 1/2 job per hour. Similarly, the second painter can finish the job in 8 hours, so their work rate is 1/8 job per hour.
When the two painters work together, their combined work rate is the sum of their individual work rates. So, the total work rate when they work together is 1/2 + 1/8 = 5/8 job per hour.
To find the time it would take them to finish the job, we can use the formula time = 1 / work rate. Substituting in the combined work rate of 5/8 job per hour, we get:
time = 1 / (5/8) = 8/5 = 1.6
Therefore, it would take the two painters approximately 1.6 hours or 1 hour and 36 minutes to finish the job if they were working together.

If EFGH is a parallelogram, what is the value of x?
A quadrilateral in which opposite sides are parallel is called a parallelogram. The value of x is 37.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
For a parallelogram, any two adjacent angles are always supplementary. Therefore, we can write the sum of the two angles as,
(4x-2)° + 34° = 180°
4x - 2 + 34 =180
4x + 32 =180
4x = 180 - 32
4x = 148
x = 37
Hence, the value of x is 37.

Step-by-step explanation:
Given is that -
Pollsters take a survey of people at a ball game to collect and analyze data about favorite leisure activities of star city’s residents.
This study will be biased and it will produce biased results.
Firstly, few people at ball game do not represent the whole population of the city and it is not necessary that all the people at ball park will respond to the question in the survey.

A quality control expert randomly samples 60 pairs of sunglasses and finds 5 defective pairs. predict how many defective pairs will be in a shipment of 420 sunglasses.
For this case the first thing you should do is find the percentage of sunglasses that are defective.
For this, we make the following rule of three:
60 pairs -------------------> 100%
5 pairs ---------------------> x
From here, we clear the value of x.
We have then:
[tex] x = (\frac{5}{60}) * (100)
x = 8.3%
[/tex]
We now look for the amount of sunglasses that may come with defects.
We have then:
[tex] N = (0.083) * (420)
N = 34.86
[/tex]
Rounding to the nearest whole number:
[tex] N = 35
[/tex]
Answer:
About 35 defective pairs will be in a shipment of 420 sunglasses
Use graphs and tables to find the limit and identify any vertical asymptotes of the function.
Answer:
The limit of the function is [tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex] and the vertical asymptotes is x=8.
Step-by-step explanation:
The given function is
[tex]f(x)=\frac{1}{x-8}[/tex]
We need to find the value of
[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}[/tex]
The graph of the function f(x) is attached below.
From the graph it is clear that the function approaches to -∞ as x approaches to 8 from left. So, by the graph we can say that
[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex]
The table of values is attached below. From the table it is clear that the value of f(x) decreasing as the value of x is closed to 8 from left. So, by the table we can say that
[tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex]
To find the vertical asymptotes equate denominator, equal to 0.
[tex]x-8=0[/tex]
[tex]x=8[/tex]
Therefore the limit of the function is [tex]lim_{x\rightarrow 8^-}\frac{1}{x-8}=-\infty[/tex] and the vertical asymptotes is x=8.

A circular mirror has a diameter of 12 inches. part a what is the area, in square inches, of the mirror?
a. 6 π
b. 12 π
c. 36 π
d. 72 π part b a circular frame that is 3 inches wide surrounds the mirror. what is the combined area, in square inches, of the circular mirror and the frame?
a. 9 π
b. 18 π
c. 54 π
d. 81 π
Final answer:
The area of the circular mirror is 36π square inches, and the combined area of the mirror and frame is the difference between the total area with the frame (81π square inches) and the mirror alone, resulting in 45π square inches.
Explanation:
Part A: Area of the Circular Mirror
To find the area of the circular mirror, we use the formula for the area of a circle, which is A = πr², where r is the radius of the circle. Since the diameter of the mirror is given as 12 inches, the radius would be half of that, which is 6 inches. Plugging the radius into the formula, we get:
A = π(6 inches)² = 36π square inches
Part B: Area of the Circular Mirror and Frame
The frame adds 3 inches to the radius on all sides, making the overall radius of the mirror and frame 9 inches (6 inches + 3 inches). Using the area formula again, A = π(9 inches)² = 81π square inches.
To find the combined area of the mirror and frame, we subtract the area of the mirror from the total area. Hence, combined area = 81π square inches - 36π square inches = 45π square inches.
