One label on a package of bolts says that each bolt has a diameter of 0.45 inch. To be in the package, the percent error of the diameter must be less than 4%. A test on the production line shows a bolt with a diameter of 0.43 inch. Should this bolt go into the package?
Answers
Answer:
No, should notStep-by-step explanation:
The diameter is 0.45 in
The percent error is < 4%
The lower limit of allowance is:
0.45 - 4% = 0.45*(1 - 0.04) = 0.45*0.96 = 0.432Less than 4% error means the diameter should be greater than 0.432 in.
The bolt with the diameter 0.43 in is outside of the allowance and should not go into the package

Step-by-step explanation:
12x + 15 = 5x + 85 {Subtract 15 from both sides}
12x + 15 - 15 = 5x + 85 - 15
12x = 5x + 70 {Subtract 5x from both sides}
12x - 5x = 70
7x = 70 {Divide both sides by 7}
x = 70/7
x = 10
∠U = 5x = 5*10 = 50

The volume of the cylinder is 235.6 cubic feet. Find the height. Round your answer to the nearest whole number.
Answers
Answer: 3 feet
Step-by-step explanation:
Here's the complete question:
The volume of the cylinder is 235.6 cubic feet the radius is 5ft. Find the height.
Note that Volume of a cylinder = πr²h
where Volume = 235.6 feet³
Radius = 5 feet
Height = Unknown
Then, we put the values back into the question and this will be:
V = πr²h
235.6 = 3.14 × 5² × h
235.6 = 3.14 × 25 × h
235.6 = 78.5 × h
h = 235.6 / 78.5
h = 3 feet
The height is 3 feet
Y/-3=1/6 HELP PLEASE
Answers
Answer:
y = -0.5
Step-by-step explanation:
Since 6 can be multiplied to -3, we can make an equation to make 6 turn into -3
6 ÷ -2 = -3
So since we did that with 6, the denominator, we do the same with 1, the numerator
1 ÷ -2 = -0.5
So the new numerator is -0.5, and the new denominator is -3

Find the measures of the numbered angles in each rhombus
Answers
Answer:
2=41 1=49 3=49
Step-by-step explanation:
Angle 2 = 41 because it is directly across the given angle.
Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.
41+41=82
180-82=98
98 / 2 = 49
Angles and 3 both equal 49
Answer:
2=41°(Alternate Interior angles)
1=41°(diagonal of rhombus bisects the interior angles)
3=49°(180-82/2)
Step-by-step explanation:
Select the correct answer.
The sum of two complementary angles is 90°. For one pair of complementary angles, the measure of the first angle is 15 less than twice the
measure of the second angle. Write system of equations that can be used to determine the measure of the first d, angle, a, and the measure of
the second angle, b.
A. a+b=90, 2b-15=a
B. a+b=90, 2b+15=a
C. a+b=90, a-2b=15
D. a+b=90, 2a-15=b
Answers
Answer:
A
Step-by-step explanation:
The first angle (a) is 15 less than twice the second angle (b)
So, twice the second angle is 15 more than the first:
2b = a+15
Simplify:
2b - 15 = a

Answers
Answer:
y = -2/3 + 18
Step-by-step explanation:
2x + 3y = 18 ----- here is the equation...
-2x - 2x ----- bring the 2x to the other side
3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself
y = -2/3 + 18 ----- Done!
Answer:
y= -2/3x + 6

Subtract 2 from both sides of the Equation:
3y=18-2x
Divide each term by 3 and simplify:

What is the median of the data?
Enter your answer as a number, like this: 42
Answers
Answer:
22
Step-by-step explanation:
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
The median of the data is given by M = 22
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
Let the median of the data be represented as M
Now , the values of the data are given by set A
where the value of A = { 23 , 21 , 21 , 25 , 27 , 16 , 55 , 3 , 11 , 38 }
Now , arranging the values in ascending order is
A = { 3 , 11 , 16 , 21 , 21 , 23 , 25 , 27 , 38 , 55 }
The number of elements = 10
So , the median is M = ( 21 + 23 ) / 2
M = 44/2
M = 22
Therefore , the value of M is 22
Hence , the median is M = 22
