Final answer:
It takes 3.5 minutes for a copy machine to make 154 copies at a rate of 44 copies per minute.
Explanation:
To find out how long it takes for a copy machine to make 154 copies at a rate of 44 copies per minute, we need to perform a division calculation. First, we divide the total number of copies needed (154 copies) by the rate at which the machine produces copies, which is 44 copies per minute.
The calculation is as follows:
154 copies ÷ 44 copies per minute = 3.5 minutes.
This means it would take the copy machine 3.5 minutes to produce 154 copies.

The given equation is -2x-11y=5, We need to find the slope intercept equation, slope and y intercept.
What is slope intercept form of a line?y=mx+c
m is the slope of the line
c is the y intercept of line
The given equation is -2x-11y=5
We need to separate the y variable to find the slope intercept form
-11y=5+2x
To convert the above equation to slope intercept form, we need to divide both sides by -11.
y=-5/11-2/11x
Therefore y=-2/11x-5/11 is the required slope intercept form for -2x - 11y = 5
Slope is -2/11
y intercept is -5/11

It takes the earth 24 hours to complete a full rotation. It takes mercury approximately 58 days, 15 hours, and 30 minutes to complete a full rotation. How many hours does it take mercury to complete a full rotation?
Mercury takes approximately 1407.5 hours to complete a full rotation, calculated by converting 58 days, 15 hours, and 30 minutes entirely into hours.
Explanation:To calculate how many hours it takes for Mercury to complete a full rotation, we need to convert the given time of approximately 58 days, 15 hours, and 30 minutes into hours. Here are the step-by-step calculations:
First, convert the days into hours. Since there are 24 hours in a day, we multiply 58 days by 24 hours per day.58 days × 24 hours/day = 1392 hoursNext, add the additional hours to the total from the days.1392 hours + 15 hours = 1407 hoursFinally, convert the minutes to hours. There are 60 minutes in an hour, so we divide 30 minutes by 60.30 minutes ÷ 60 minutes/hour = 0.5 hoursAdd this to the total number of hours.1407 hours + 0.5 hours = 1407.5 hoursTherefore, it takes Mercury approximately 1407.5 hours to complete a full rotation.

Which word describes the slope of the line?
positive
negative
zero
undefined
Answer:
positive
Step-by-step explanation:
The slope is the inclination of the line with respect to the x-axis. It is denoted by the letter [tex]m[/tex]. In mathematical language, the slope [tex]m[/tex] of the line is defined as the difference on the y-axis divided by the difference on the x-axis for two different points [tex]P_1(x_1,y_1)[/tex] and [tex]P_2(x_2,y_2)[/tex] on the line:
[tex]m=\frac{\Delta y}{\Delta x} =\frac{y_2-y_1}{x_2-x_1}[/tex]
If:
[tex]m>0[/tex] The slope is positive and the line is increasing from left to right[tex]m<0[/tex] The slope is negative and the line is decreasing from left to rightIf a line is vertical the slope is undefined[tex]m=0[/tex] is a constant function.
Since the graph of the linear function shown is increasing from left to right, we can conclude that the slope is positive.
Solve for a. 15(25−5a)=4−a
A- 0
B-−1
C-all real numbers
D- no solution
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
[tex]\dfrac{1}{5}(25-5a)=4-a[/tex]
We need to find the value of 'a'.
First we simplify the brackets :
[tex]\dfrac{1}{5}(25-5a)=4-a\\\\25-5a=5(4-a)\\\\25-5a=20-5a\\\\25-20=-5a+5a\\\\5=0[/tex]
which is wrong.
Hence, there is no solution.
Therefore, Option 'D' is correct.

Answer: This is the CORRECT answer ----> y = 2x + 20
Step-by-step explanation: slope, y2 - y1/x2 - x1
replace it with these numbers 120 - 60/50 - 20=60/30
than,simplified it we get 2/1. so, now we have the slope of our equation
y = 2x + b. but we still have b (or where the y intersects.) now are slope we have to change it to 1/2 because we are going backwards. So multiply 60 by .5, Thus will give us 30
Now we have y = 2x + 30, But that's not one of your answer,
So y = 2x + 20 cant be -20 because this is a positive y intersect and We know it is a slope of 2.
Therefore the answer is : y = 2x + 20
ALSO I know it's correct because I got it right on the test!! Hoped I helped :))

For safety. the recommended height of a zebra fence is 5 ft. Because of uneven ground surfaces, the actual height of the fence can vary from recommendation by 3 inWrite and solve an absolute value equation to find the maximum and minimum heights of the fence. Then, find the maximum and minimum heights of the fence
The maximum and minimum heights for the zebra fence, considering the 3-inch allowance, are 5.25 feet (63 inches) and 4.75 feet (57 inches), respectively. This was computed by converting the standard height to inches, and applying an absolute value equation to figure out the range for the fence's height.
Explanation:The recommended height of the fence is 5 ft, but this can vary by 3 inches due to uneven ground surfaces. The question asks for an equation to calculate the maximum and minimum heights.
To start, we need to convert all measurements to the same units. 5 feet is equivalent to 60 inches.
Next, we can set up the absolute value equation to represent the possible variation in height. This may look like |x - 60| ≤ 3. Here, x is the actual height of the fence.
Then, solve the equation to get our two possible results: x ≤ 60 + 3 and x ≥ 60 - 3. Therefore, the maximum and minimum heights of the fence are 63 inches (or 5.25 feet) and 57 inches (or 4.75 feet) respectively.
