An absolute value inequality for 35 degrees C with the temperature able to vary as much as 1% is 34.65 ≤ x ≤ 35.35
The term inequality is defined as a relationship between two expressions or values that are not equal to each other
Here we have given that in your chemistry experiment, you are trying to keep the water temperature at 35°C.
And in the experiment to work properly, here the actual temperature can vary as much as 1%.
Here let us consider that x refers the actual temperature
Then it can be written as,
=> 1% of 35
When we simplify this one then we get,
=> 0.01(35) = 0.35
Here let us consider that the value is less that the simplified version, then it can be written as,
=> l x - 35 l ≤ 0.35
Therefore, it can be rewritten as,
=> -0.35 ≤ x - 35 ≤ 0.35
When we simplify this by add the value 35, then we get the resulting inequality as,
=> 34.65 ≤ x ≤ 35.35

What is midpoint formula Class 11?
The midpoint formula is a mathematical formula used to find the midpoint of a line segment, given the coordinates of the two endpoints of the segment. In class 11, it is defined as:
Midpoint = ( (x1 + x2)/2 , (y1 + y2)/2 )
Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment, and (x, y) are the coordinates of the midpoint of the segment.
For example, if the two endpoints of a line segment are (5,6) and (9,11)
Midpoint = ( (5 + 9)/2 , (6 + 11)/2 )
Midpoint = (7,8.5)
The midpoint of the line segment with endpoints (5,6) and (9,11) is (7,8.5)
It's worth noting that this formula can be adapted for three-dimensional points, where the midpoint formula would be
((x1 + x2)/2, (y1 + y2)/2, (z1 + z2)/2)

We must determine,
The trend line equation is used to calculate the hiker's elevation after 150 minutes.
In response to the question,
A trend line's equation for the hiker's elevation is y = 9.16x + 659.
Where x is the number of minutes and y is the elevation of the hiker in feet.
Substitute the value of x = 150minute in the given equation to find the trend line to estimate the hiker's elevation after 150minutes.

Enlarging or contracting a figure's size is known as dilatation. In other words, a scale factor is used to either enlarge or diminish the image while maintaining similarity between the preimage and the image.
What Is A Dilation ?In line with the illustrations below. A dilation that produces a smaller image is called a reduction (conjure up shrinking), whereas a dilation that produces a larger image is called an enlargement (conjure up stretching).Image reduction occurs when the scale factor is between 0 and 1.An expansion of the image occurs when the scale factor exceeds 1.The center point of the dilation is located, and the distances between this center point and various points on the preimage and the image are measured in order to determine the scale factor for the dilation. According to Math Bits Notebook, we can determine the scale factor by dividing these distances by two.Given that each angle is congruent, each segment is proportional, the slope of each segment is preserved, and the perimeter of the preimage and image have the same scale factor, using dilation scale factors allows us to enlarge or reduce a figure to the desired size.To Learn more About dilatation Refer To:

C=36x+200
R=76x
Break-even point: ([],[])
Answer:
The break even point is 380.
Step-by-step explanation:
36x + 200 = 76x
200 = 76x - 36x
200 = 40x
200/40 = x
5 = x
C = 36(5) + 200 R = 76(5)
C = 180 + 200 R = 380
C = 380
Answer:
The breakeven point is 5 units
Step-by-step explanation:
C is the cost ($) and R is the revenue ($).
We are told that :
R=76x
C=36x+200
Profit would be the Revenue minus the Cost:
Profit = R - C
The "breakeven point" is the situation in which there is neither a profit nor a loss. That means that the total profit equals the total cost for x units. We want to find the value of x that would result in no profit or loss: Profit = 0.
0 = R-C
====
Profit = 76x - (36x+200)
Profit = 40x - 200
0 = 40x - 200 [The Breakeven Point]
-40x = -200
x = 5 units
5 units results in 76*5 or $380 in revenue.
5 units results in a cost of 36*(5)+200 or $380 in costs.
The result is breakeven (Profit = $390 - $380) of $0.00
