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. What is the average rate of change in steel production over the eight days? Express the answer in tons per day.
A. +1.2
B. -1.2
C. +0.15
D. -0.15
Answer:
option D.
Step-by-step explanation:
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
so sorry -0.15

Step-by-step explanation:
Rewrite the formula to solve for the positive value of r in terms of h and v.
Answer:
[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
Step-by-step explanation:
The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
Where
r is radius of cone and h is its height
We need to solve the above formula for r.
Cross multiplying both sides of the given formula
[tex]3V=\pi r^ 2h[/tex]
Dividing both sides by πh.
[tex]\dfrac{3V}{\pi h}=\dfrac{\pi r^2 h}{\pi h}\\\\r^2=\dfrac{3V}{\pi h}\\\\r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
So, the formula for r is [tex]\sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:
-¼ ( x + 2) + 5 = - x
( this is a multi-step equation)
The value of x after simplfication of equation -¼ ( x + 2) + 5 = - x is -6.
Consider the equation,
( - 1 / 4 ) × ( x + 2 ) + 5 = - x
Now,
( - x / 4 ) + ( - 2 / 4 ) + 5 = - x
( - x / 4 ) - ( 1 / 2 ) + 5 = - x
Now, LCM of 2 and 1 is 2.
Therefore,
( - x / 4 ) + [ ( 10 - 1 ) / 2 ] = - x
( - x / 4 ) + ( 9 / 2 ) = - x
Adding x on both sides of the equation.
( - x / 4 ) + x + ( 9 / 2 ) = - x + x
Subtracting ( 9 / 2 ) from each side of the equation,
( - x / 4 ) + x + ( 9 / 2 ) - ( 9 / 2 ) = ( - 9 / 2)
( - x / 4 ) + x = ( - 9 / 2 )
LCM of 4 and 1 is 4
[ ( - x + 4x ) / 4 ] = ( - 9 / 2 )
( 3x / 4 ) = ( - 9 / 2 )
By cross multiplying,
2 × 3x = - 9 × 4
6x = - 36
Dividing each side of the equation by 6.
( 6x / 6 ) = ( - 36 / 6 )
x = - 6

Answer:
Q1. [tex](-\frac{3}{2},0)[/tex]
Q2. (-16, 0)
Step-by-step explanation:
The midpoint of a line segment is given by the formula:
[tex]\boxed{\text{Midpoint}=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )}[/tex]
In the formula, [tex](x_1,y_1)[/tex] is the first endpoint while [tex](x_2,y_2)[/tex] is the second endpoint of the line segment.
__________
Q1. Substitute the given endpoints into the formula:
Midpoint
[tex]=(\frac{-5+2}{2} ,\frac{5-5}{2} )[/tex]
[tex]=(\frac{-3}{2} ,\frac{0}{2} )[/tex]
[tex]= \bf{(-\frac{3}{2} ,0)}[/tex]
__________
Q2. Let the other endpoint be (x, y).
Substitute the given midpoint and one endpoint:
(-6, 4)=[tex](\frac{x+4}{2} ,\frac{y+8}{2} )[/tex]
Comparing the x-coordinate:
[tex]\frac{x+4}{2} =-6[/tex]
Multiply both sides by 2:
x +4= -12
Subtract 4 from both sides:
x= -12 -4
x= -16
Comparing the y-coordinate:
[tex]\frac{y+8}{2} =4[/tex]
Multiply both sides by 2:
y +8= 8
Subtract 8 on both sides:
y= 8 -8
y= 0
The coordinates of the other endpoint is thus (-16, 0).

your own work, please ...
my own work is
1.
the midpoint between 2 points (x1, y1) and (x2, y2) is
((x1 + x2)/2, (y1 + y2)/2)
so, our midpoint is
((-5 + 2)/2, (5 + -5)/2) = (-3/2, 0/2) = (-3/2, 0)
2.
we have
((x1 + 4)/2, (y1 + 8)/2) = (-6, 4)
so,
(x1 + 4)/2 = -6
x1 + 4 = -12
x1 = -16
(y1 + 8)/2 = 4
y1 + 8 = 8
y1 = 0
so, the other endpoint is (-16, 0).

Movie a costs 4 dollars
Movie b costs 5 dollars
Movie theater got 200 dollars and sold 47 tickets
How many tickets did movie a sell
Answer:
ticket for movie A = 35
ticket for movie B = 12
Step-by-step explanation:
Let A= is ticket for movie A
Let A= is ticket for movie B
We have A + B = 47 (1)
4A + 5B = 200 (2)
From (1) multiply 5 in both side 5A + 5B = 47(5)= 235
4A + 5B = 200
So A = 35
B= 47-35 = 12

Answer:
30/75 2/5
Step-by-step explanation:
there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75. This can be simplified to 2/5 if both sides are divided by fifteen.
To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%

This question is incomplete, the complete question is;
In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 58 items is selected. The mean of the sample is determined to be 36. The associated number of degrees of freedom for reading the t value is :
a. 35.
b. 57.
c. 36.
d. 58.
Answer: Option b. 57 is the correct answer.
Step-by-step explanation:
Given that;
sample size n = 58
sample mean x" = 36
degrees of freedom for reading the t value is = ?
we know that;
Degree of freedom df = n - 1
where n is the sample size
so we substitute
Degree of freedom df = 58 - 1
Degree of freedom df = 57
Therefore Option b. 57 is the correct answer.

A vacation home in Orlando, Florida, rents for $130 per day. The function (x) = 130x gives the cost of renting the
home for x days. What is the reasonable range of the function in this context?
The reasonable range of the given function is given by {130, 260, 390, 520, .......}.
What is a range?A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range simply refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.
How to determine the reasonable range of the given function?In order to determine the reasonable range of the given function, we would create an input and output table to model the relationship between the range and domain as follows:
x 130x y___
1 130(1) 130
2 130(2) 260
3 130(3) 390

Find an expression which represents the sum of (10x - 4y) and (4x -8y) in simplest terms.
Answer:
14x - 12y
Step-by-step explanation:
Let's write the sum:
(10x - 4y) + (4x -8y)
Because we're only doing addition and subtractaction, we can drop the parentheses that aren't preceded by a minus sign, they don't change the order.
10x - 4y + 4x - 8y
as long as we don't change the sign preceding each component, we can reorder as we wish
10x + 4x - 4y - 8y
(10x + 4x) - (4y + 8y)
note that because we added a parenthesis preceded by a - the sign inside changed.
We perform additions inside of the parentheses:
10x + 4x = 14x
4y + 8y = 12y
and we arrive at the final result:
14x - 12y
Simplify and answer the boxes.
