The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. Which function could represent this situation?
f(x ) = x – |42.67|
f(x ) = |x| – 42.67
f(x ) = |42.67 – x|
f(x ) = 42.67 – |x|
Answer:
c
Step-by-step explanation:
The function that could represent this situation is f(x ) = |42.67 – x| (Option C).
What quality control?The process of quality control helps a producer to ensure that the correct standard is maintained in the production of goods. It involves the testing of products to ensure that they conform to specifications.
Now we are told that factory wants to ensure that the discrepancy in diameter is not more than 0.002 mm. Since the discrepancy could be above or below the given value then it follows that the function that could represent this situation is f(x ) = |42.67 – x| (Option C).

A group of 8 friends went to lunh and Spent a total of $76 which included the food bill in the tip of $16 they decide to split the bill into evenly among themselves
Answer:
The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
The solution x=60 represents the total food bill.
Step-by-step explanation:
As in the question it is mentioned that there is eight group of friends and the total amount incurred is $76 that also involved $16
Now let us assume the food bill be x
So the equation would be
(x + 16) ÷ 8 = 76 ÷ 8
(x + 16) ÷ 8 = 9.5
x + 16 = 9.5 × 8
x = 76 -16
x = 60
So, the bill of food is 60

what would be the measure of angle A?
A. 70 degrees
B. 79 degrees
C. 55 degrees
D. 44 degrees
Answer:
D because that is the smallest angle on there baby doll
Step-by-step explanation:
have a nice day sugar bear
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4x + 8x - 9 + 57 = 180, that is
12x + 48 = 180 ( subtract 48 from both sides )
12x = 132 ( divide both sides by 12 )
x = 11
Thus
∠ A = 4x = 4 × 11 = 44° → D

An airplane travels at a constant speed of 320 miles per hour. How far, in miles, will the airplane travel in 15 minutes?
Answer:
80 miles.
Step-by-step explanation:
If it is traveling at 320 miles per hour, and its asking how much its traveled in 15 minutes you do this:
Since 15 minutes is 1/4 of an hour, you take 1/4 of how fast they are traveling at mph, which in this case is 320 mph.
320/4=80
The airplane will travel 80 miles in 15 minutes.
What is Distance?The length along a line or line segment between two points on the line or line segment.
we need to use the formula of distance.
distance = speed × time
Since the speed of the airplane is 320 miles per hour, we need to convert 15 minutes to hours:
15 minutes = 15/60 = 0.25 hours
Now we can substitute the values into the formula:
distance = speed × time
distance = 320 × 0.25
distance = 80
Therefore, the airplane will travel 80 miles in 15 minutes.

The first five terms of an arithmetic sequence are 8, 13/2, 5, 7/2, and 2. Which function, f(x), could be used to describe the xth term of the sequence?
Answer:
f(x) = 8 - 1.5x
Step-by-step explanation:
Here, we want to write a function that can be used to describe the x th term of the sequence
Mathematically, this can be calculated by looking at the numbers in the sequence
The difference between each successive term
is -1.5 ( 6.5-8, 3.5 -5)
So the formula for then x th term will be;
f(x) = 8 - 1.5x
where x refers to the number of the term , for example the 4th term
Answer:
-1.5x+9.5
Step-by-step explanation:
-1.5(1)+9.5=8
-1.5(2)+9.5=6.5
-1.5(3)+9.5=5

Answer:
3x-14=2x+10
add 14 to both sides
3x-14+14=2x+10+14
3x=2x+24
subtract 2x from both sides
3x-2x=2x+24-2x
x=24
Plug x into the equations
3(24)-14=58
2(24)+10=58
they are the same angle
B=122
58-180=122
116-360=244

subtract 2x from both sides
3x-2x=2x+24-2x
