Answer:
average rate of change in steel production over the eight days=-0.15 tons per day
Step-by-step explanation:
The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons.
Production is dropped by 1.2 tons, so its negative
Average rate of change = Change in production / number of days
Average rate of change = -1.2/ 8= -0.15

Given the statement 'If you have a ruby, then you have at least $1000.' and the fact that you have a ruby, the Law of Detachment leads to the conclusion 'You have at least $1000.'
Explanation:The Law of Detachment (also known as Modus Ponens) in logic says that if a conditional statement ('if p then q') is true and the first part of the statement (p) is true, then the second part of the statement (q) is true. Let's apply it to your statement.
The original statement is 'If you have a ruby, then you have at least $1000.' You confirmed the first part 'You have a ruby.' So, according to the Law of Detachment, the resulting correct statement would be 'You have at least $1000.' The other statements about selling or someone buying the ruby are irrelevant to the Law of Detachment.

Which is the more reasonable measurement of the diameter of a blood cell: 7.4 ⋅ 10−3 mm or 7.4 ⋅ 103 mm? Justify your answer.
Answer:
[tex]7.4\times 10^{-3}\ mm[/tex]
Step-by-step explanation:
Actual measurement of diameter of a blood cell is 6 to 8 μm
Let diameter be d
[tex]1\mu m=10^{-6}\ m[/tex]
[tex]6\times 10^{-6}\ m\leq d\leq 8\times 10^{-6}\ m[/tex]
Now we check the given measurement between the range.
[tex]7.4\times 10^{-3}\ mm[/tex]Change into meter. As we know 1000 mm = 1 m or 1 mm = 10⁻³ m
[tex]7.4\times 10^{-3}\times 10^{-3}\ m[/tex]
[tex]7.4\times 10^{-6}\ m[/tex]
[tex]7.4\times 10^{3}\ mm[/tex][tex]7.4\times 10^{3}\times 10^{-3}\ m[/tex]
[tex]7.4\ m[/tex]
So, [tex]7.4\times 10^{-6}\ m[/tex] lie between [tex]6\times 10^{-6}\ m\leq d\leq 8\times 10^{-6}\ m[/tex]
Hence, [tex]7.4\times 10^{-6}\ m[/tex] more reasonable measurement of diameter of blood cell because it lies between range of diameter of blood cell.

Jack wants to fill a rectangular box with sand. The length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. Each bag of sand contains 0.15 cubic foot of sand. How many bags of sand will Jack need to fill the box completely?
[1 foot = 12 inches]
Numerical Answers Expected!
The number of bags of sand that Jack need to fill the box completely are:
2
Step-by-step explanation:The length(l) of the sand box is 3 feet, width(w) is 6 inches, and height(h) is 2.4 inches.
Also,
1 foot=12 inches
This means that:
1 inch=1/12 foot
i.e.
6 inches=0.5 feet
i.e.
w=0.5 feet
and
h=2.4 inches
i.e. h=0.2 feet
Now, we find the volume of the rectangular box.
The volume of the rectangular box is given by:
Volume=lwh
Hence,
Volume=3×0.5×0.2
i.e.
Volume=0.3 cubic feet.
Also, the volume of one bag of sand= 0.15 cubic feet
This means that the number of bags of sand that will fill the box completely is:
(Volume of rectangular box) / (Volume of one bag of sand)
= 0.3/0.15
=2
Hence, number of bags =2

A box contains 19 large marbles and 11 small marbles. each marble is either green or white. 5 of the large marbles are green, and 6 of the small marbles are white. if a marble is randomly selected from the box, what is the probability that it is large or green? express your answer as a fraction or a decimal number rounded to four decimal places.
The probability that a randomly selected marble is either large or green is approximately 0.6333 or you can express it as a fraction: 19/30.
Consider the total number of marbles that satisfy either of these conditions.
Total large marbles: 19
Total green marbles: 5
However, the large marbles include the green marbles, so we need to subtract the overlap:
Number of large green marbles: 5
Total marbles that are either large or green = Total large marbles + Total green marbles - Number of large green marbles
Total marbles that are either large or green = 19 + 5 - 5
= 19
Now, we'll find the probability by dividing the total marbles that are either large or green by the total number of marbles:
Probability = (Total marbles that are either large or green) / (Total number of marbles)
Probability = 19 / (19 + 11)
Probability ≈ 0.6333 (rounded to four decimal places)
Therefore, the probability that a randomly selected marble is either large or green is approximately 0.6333 or you can express it as a fraction: 19/30.

The probability that randomly selected marble from the box is large or green is 0.7667.
Explanation:The probability of selecting a large or green marble from a box can be found by analysing the given information. We have 19 large marbles, out of which 5 are green. We also have 11 small marbles, out of which 6 are small and green since small marbles cannot be large. This means there are a total of 30 marbles (19 large and 11 small), and 9 of them are green. To calculate the probability that a marble is large or green, we need to include all large marbles (since they meet one condition) and add the small green marbles (since they meet the other condition, but aren't already counted with the large marbles).
The number of favorable outcomes is therefore 19 (large marbles) plus 4 (small green marbles), since 5 large marbles have already been counted as green, we don't count them again. That makes a total of 23 favorable outcomes. The probability is the number of favorable outcomes divided by the total number of marbles:
Probability = 23 / 30. As a decimal rounded to four places, this is approximately 0.7667.
Define a variable and write an expression for the phrase.
the quotient of 2 times a number and 8
.
Answer:
The expresion for the phrase is:
[tex]\frac{2x}{8}[/tex]
Step-by-step explanation:
In order to get the expression for the phrase, we have to understand the described operations in it.
The phrase starts with "the quotient of...", therefore the expression must be a fraction:
[tex]\frac{A}{B}[/tex]
To get what is the numerator (A) and the denominator (B), we have to analyze carefully the rest of the phrase: "...2 times a number and 8"
In this case, the word "and" separates the numerator from the denominator:
Numerator: "2 times a number"
This unknown number is called x
Therefore, numerator of the fraction (A) is:
[tex]A = 2x[/tex]
And the Denominator: "8"
Therefore: [tex]B=8[/tex]
Finally, replacing values:
[tex]\frac{A}{B} = \frac{2x}{8}[/tex]

Two cars leave the same location traveling in opposite directions. One car leaves at 3:00 p.m. traveling at an average rate of 55 miles per hour. The other car leaves at 4:00 p.m. traveling at an average rate of 75 miles per hour. Let x represent the number of hours after the first car leaves. How many hours after the first car leaves will the two cars be 380 miles apart?
Enter an equation that can be used to solve this problem in the first box. Solve for x and enter the number of hours in the second box.
Equation:
x =
x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours

The length of one side of a square is 3n+2. The Perimeter of the square is 4(3n+2).Which expression is equivalent to the perimeter.
Answer:
[tex]P=12n+8[/tex]
Step-by-step explanation:
A square is a geometric figure that is made up of four equal and parallel sides.
The perimeter is the contour of a surface or figure. In other words, in a figure, the perimeter is the sum of all its sides.
In this sense, since in a square all its sides are equal, the perimeter of a square is given by:
[tex]Perimeter=P=l+l+l+l=4l\\\\Where:\\\\l=Length \hspace{3}of \hspace{3}one\hspace{3} of\hspace{3} its\hspace{3} sides[/tex]
So, in this case:
[tex]l=3n+2[/tex]
Therefore the perimeter is:
[tex]P=3n+2+3n+2+3n+2+3n+2[/tex]
Adding like terms:
[tex]P=(3n+3n+3n+3n)+(2+2+2+2)=12n+8[/tex]

The equation for the cost in dollars of producing computer chips is y =.000015x^2-.03x+35. Where x is the number of chips produced . Find the number of chips that minimizes the cost. What is the cost for that number of chips?
1000 chips minimize the production cost in the given equation, and the minimum cost for producing these chips is $20.
Explanation:To find the number of chips that minimizes the cost in the given quadratic equation, y = 0.000015x^2 - 0.03x + 35, we can use the vertex formula for a parabola, which is derived from the general quadratic equation.
The general form of a quadratic equation is y = ax^2 + bx + c, and the x-coordinate of the vertex, which gives us the number of chips that minimizes the cost, can be found using x = -b/(2a). For our equation, a = 0.000015 and b = -0.03.
Substituting the values of a and b into the vertex formula:
x = -(-0.03)/(2 * 0.000015)x = 0.03/0.00003x = 1000 (number of chips)Now, we plug this value back into the original equation to find the minimum cost:
y = 0.000015(1000)^2 - 0.03(1000) + 35y = 15 - 30 + 35y = $20 (cost for producing 1000 chips)This gives us the minimum cost and the number of chips that lead to this cost. Therefore, 1000 chips minimize the cost, and the minimum cost for producing these chips is $20.
Line segment YZ was used to translate ABCDE. YZ is 5.5 inches long.what is the length of AA + BB + CC + DD +EE?
Answer:
AA' + BB' + CC' + DD' +EE' = 27.5 inches
Step-by-step explanation:
A translation moves all points of a figure the same distance in the same direction. If line segment YZ is 5.5 inches long, then the distance between original point A and translated point A' would be 5.5 inches. That is also valid to the other points. So, length of AA' = BB' = CC' = DD' = EE' = 5.5 inches. In consequence, AA' + BB' + CC' + DD' +EE' = 5*5.5 inches = 27.5 inches
