So, 12 divided by 144140 is approximately 0.000083158.
Division is a mathematical operation used to distribute a quantity or a number of items into equal parts. It involves finding out how many times one number (called the divisor) can be subtracted or taken away from another number (called the dividend) until there is nothing left or the subtraction cannot be done anymore.
The result of the division is called the quotient, and it represents the number of equal parts or groups that the dividend can be divided into by the divisor. In the division expression "a ÷ b," where "a" is the dividend and "b" is the divisor, the quotient is represented by "a/b."
For example, in the division 12 ÷ 3:
12 is the dividend (the total quantity to be divided).
3 is the divisor (the number of equal parts to divide the dividend).
The quotient is 4, as 12 can be divided into 4 equal parts of size 3.
Division is the opposite operation of multiplication. If you have two numbers, the product of their multiplication can be divided by one of the numbers to get the other number. For example, 12 × 3 = 36, and 36 ÷ 3 = 12.

How large is the sample?
a.200 cartons
b.the 50th carton
c.1000 cartons
d.cannot determine from this information
Answer:
Option a is correct
200 cartons is the sample size
Step-by-step explanation:
As per the statement:
For ten shipments of 1000 cartons of eggs, she examines every 50th carton to see how many cartons contain cracked eggs.
First examine how many cartons are examined per shipment.
For every 50th cartons, 1 are examined
For every 100th cartons, 2 are examined
then;
For 1000 cartons , we have 20 are examined.
Examined per shipment = 20 cartons
We have to find how large is the sample.
Since, there are total 10 shipment
then;
For 10 shipment, we have
[tex]20 \times 10 = 200[/tex] cartons
Therefore, 200 cartons is the sample size

Straight-line depreciation is a method of calculating an asset’s value by subtracting its salvage value from its acquisition or purchase price divided by the estimated useful life of the asset. suppose a manufacturing robot cost $1.5 million in 2005 and is sold in 2010 for $50,000. what is the linear equation representing the value of the robot?
Answer:
Linear equation is V(t) = 1500 - 290t
Step-by-step explanation:
To find the linear equation representing the value of the robot we will calculate per year depreciation in the cost of the robot.
Rate of depreciation = [tex]\frac{\text{(Manufacturing cost in 2005-selling price in 2010)}}{5}[/tex]
= [tex]\frac{[(1.5)(10^{6})-50000]}{5}[/tex]
= [tex]\frac{(1500000-50000)}{5}[/tex]
= [tex]\frac{1450000}{5}=290000[/tex]
If depreciation is represented by V(t) (in $000) then equation will be
V(t) = 1500 - 290t

Erica bought 3 1/2 yards of fabric. If she uses 2/3 of the fabric to make a curtain, how much will she have left?
Final answer:
Erica will have 1 1/6 yards of fabric left after using 2/3 of the 3 1/2 yards she purchased to make a curtain.
Explanation:
The student's question is about how much fabric Erica will have left after using 2/3 of the 3 1/2 yards she bought to make a curtain. To solve this problem, we first need to convert the mixed number of yards of fabric to an improper fraction. We start by multiplying the whole number, 3, by the denominator of the fraction, 2, and then adding the numerator, 1. This gives us (3 × 2) + 1 equals 7, so Erica has 7/2 yards of fabric.
Next, we determine how much fabric she uses by multiplying 7/2 yards by 2/3. Doing the multiplication, (7/2) × (2/3), we can cancel out the common factor of 2 to simplify the calculation. The result is 7/3 yards of fabric used for the curtain.
To find out how much fabric is left, we subtract the used fabric from the total amount Erica originally had, which is 7/2 yards. So, we calculate 7/2 - 7/3 yards. To subtract these fractions, they need to have a common denominator. Multiplying 7/2 by 3/3 and 7/3 by 2/2 gives us equivalent fractions with a common denominator of 6. We now have (21/6) - (14/6) yards, and subtracting these gives us 7/6 yards of fabric remaining. This can also be represented as 1 1/6 yards, which is how much Erica will have left after making the curtain.

What is the converse of the following true conditional? If the converse is true, rewrite the statements as a bioconditional. If either is false, give a counter example. If two lines are parallel, they do not intersect
The converse of the statement 'If two lines are parallel, they do not intersect' is 'If two lines do not intersect, they are parallel', which is false. A counterexample to this converse is skew lines that do not intersect but are not parallel. Thus, we can't write both statements as a biconditional
Explanation:The subject of your question is regarding conditional statements and their converses in mathematics. A conditional statement is often expressed in the form: 'If p, then q', where p is a hypothesis and q is a conclusion. The converse of a conditional statement switches the hypothesis and the conclusion, i.e., 'If q, then p'.
In the context of your question, the conditional statement given is 'If two lines are parallel, they do not intersect'. The converse of this statement is 'If two lines do not intersect, they are parallel'. However, this converse is not true. A counterexample can be two lines that do not intersect but are not parallel because they are skew lines, which exist in three dimensions and do not lie in the same plane. Thus, the statements can't be written as a biconditional as one is not a valid conditional.

A highway makes an angle of 6 with the horizontal. This angle is maintained for a horizontal distance of 5 miles.
To the nearest hundredth of a mile, how high does the highway rise in this 5-mile section? Show the steps you use to find the distance.
Within a specific stretch spanning 5 miles, the roadway inclines approximately 0.53 miles or 2771.64 feet, rounded to the nearest hundredth of a mile.
Trigonometric principles aid in determining the elevation gained by the highway over this distance.
Given:
An angle of ascent (θ) of 6 degrees and a horizontal distance (adjacent side) of 5 miles, our objective is to ascertain the vertical distance (opposite side).
Utilizing the tangent function in trigonometry:
[tex]\[ \tan(\theta) = \frac{{\text{{opposite}}}}{{\text{{adjacent}}}} \][/tex]
[tex]\[ \tan(6^\circ) = \frac{{\text{{height}}}}{{5}} \][/tex]
The calculation for the height is:
height = 5 × tan(6°)
Plugging in the values:
height ≈ 5 × 0.1051
height ≈ 0.5255 miles
To convert this to feet (1 mile = 5280 feet):
height ≈ 0.5255 × 5280
height ≈ 2771.64 feet
Thus, within this 5-mile segment, the roadway ascends approximately 0.53 miles or 2771.64 feet, rounded to the nearest hundredth of a mile.

Ariel wants to write 8 entries for her blog. After 2 hours, she has 5 entries left. After 4 hours, she has 2 entries left. Which graph represents Ariel's remaining entries?
graph of line going through (0, 0) with a slope of 1.5
graph of line going through (0, 2) with a slope of 2
graph of line going through (0, 8) with a slope of 1.5
graph of line going through (0, 3) with a slope of 3
Answer:
Graph of line going through (0, 8) with a slope of 1.5 represents Ariel's remaining entries
Step-by-step explanation:
Ariel wants to write 8 entries for her blog.
After 2 hours, she has 5 entries left. [tex](x_1,y_1)=(2,5)[/tex]
After 4 hours, she has 2 entries left. [tex](x_2,y_2)=(4,2)[/tex]
So, now using two point slope form:
[tex]y-y_1=m(x-x_1)[/tex] ---1
where [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
So , substituting the given points we get the equation that represents the given situation .
[tex]m = \frac{2-5}{4-2}[/tex]
[tex]m = \frac{-3}{2}[/tex]
[tex]m = -1.5[/tex]
Now,
[tex]y-5 = -1.5(x-2)[/tex]
[tex]y-5 = -1.5x+3[/tex]
Thus the slope of the given situation is 1.5
Now at x = 0
[tex]y-5 = -1.5*0+3[/tex]
[tex]y=8[/tex]
So, at 0 hour 8 entries left .
So, graph of line going through (0, 8) with a slope of 1.5 represents Ariel's remaining entries
