The depth of a local river averages 25 ft, which is represented as |−25|. In January, it measured 5 ft deep, or |−5|, and in July, it was 27 ft, or |−27|. What is the difference between depths in January and July?
2 feet
12 feet
22 feet
32 feet
Based on the depth of the local river in January and the depth of the river in July, the difference between depths in January and July is 22 feet.
What is the difference in depth?The difference in the depth between July and January can be found as:
= Absolute value of depth in July - Absolute value of depth in January
Solving for the difference in depth gives:
= 27 - 5
= 22 feet

An intersection is the point where two lines or curves meet We can find intersections graphically by plotting curves on the same graph and determining their intersection. We can find an intersection algebraically by following these steps: Solve each equation for one of the variables, calling it y. Set the expressions for y found in the first step equal and solve for the other variable, calling it x. This is the x-value of the intersection. Return the x value of the intersection back to one of the original equations and solve for y.This is the y variable for the intersection.In the graph the intersection both functions is the point when f(x)=g(x)

the concentration of the pollutant that pours into a lake is a function of time and initially increases quite rapidly, but due to the natural mixing and self-cleansing action of the lake, the concentration levels off and stabilizes at some saturation level. a train travels at a constant speed and its distance from the point of origin is a function of time. the population of a city, which is a function of time, starts increasing rather slowly, but continues to grow at a faster and faster rate.
The concentration of a contaminant that enters a lake is a function of time and initially rises rather quickly. However, it is due to the lake's inherent mixing and self-cleansing activity.
What is concentration?Concentration in chemistry is calculated by dividing a constituent's abundance by the total volume of a mixture. The terms "concentration" can refer to any type of chemical mixture, but are most frequently used to describe the solutes and solvents in solutions. There are four different types of concentrations that can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. There are different types of molar (quantity) concentrations, including normal concentration and osmotic concentration.
Concentration is frequently expressed qualitatively in everyday, non-technical language using words like "dilute" for solutions with a low concentration and "concentrated" for solutions with a high concentration.
If y increases quickly with x, the slope of the graph will be greater (i.e. will be steeper). The slope of the graph will be lower if y increases slowly with x. (i.e. will be less steeper). Straight lines result from constant slope in graphs. 1. Less investment results in a significant boost in production at first. Consequently, graph
1) Begins with a steeper slope. The rate of expansion slows down at the end, therefore the graph
2) will be more gradual. So, D is the proper graph. 2. The slope of the graph increases while train speed stays constant. As a result, graph will be
3) Straight line So, C is the proper graph. The focus rises quickly at first. Small time therefore yields large
4) an improvement in concentration Therefore, graph will be steeper in beginning. At end, the concentration becomes constant, so graph will be almost horizontal at end.
5)Thus correct graph is B. In beginning, the population increases slowly. Thus large time gives less increase in population. Therefore, graph will be less steep in beginning. At end, the population increases rapidly, so graph will be more and more steeper at end. Thus correct graph is A.

Determine the truth value of the following conditional statement. If true, explain your reasoning. If false, give a counterexample.
If ∠1 and ∠ 2 form a linear pair, they are supplementary angles.
∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In the given image ∠1 and ∠ 2 are linear pairs.
Now,
∠1 = ∠3 (opposite angle)
∠2 = ∠4 (opposite angle)
Now,
∠1 + ∠2 + ∠3 +∠4 = 360°
(∠1 + ∠2) + 180° = 360°
(∠1 + ∠2) = 180°
If the sum of two angles is 180° then they will be supplementary angles.
Hence "∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles".

yazmin noticed her favorite workout tops were on sale for $6.00 off the original price. she purchased 4 of the tops and spent a total of $51.80. write and solve an equation to determine x, the original price of the workout tops?
the original price of the workout tops is $18.95
How to find the original price of the workout tops?
Let's say that the original price is x, we know that the tops are on sale for $6.00 off the original price, so if Yazmin buys 4 of these, the cost will be:
C(x) = (x - $6.00)*4
And we know that the cost is $51.80, replacing that we get:
$51.80 = (x - $6.00)*4
Now we need to solve this linear equation for x.
$51.80/4 = x - $6.00
$51.80/4 + $6.00 = x = $18.95
We conclude that the original price of the workout tops is $18.95

ZA and ZB are
supplementary angles. If mA = (x + 4)° and m
LB = (2x - 7)°, then find the measure of ZA.
Supplementary angles have a sum of 180°
Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.
( 7x - 15 ) + ( 2x - 3 ) = 180
Now we can combine like terms and use inverse operations to find the value of x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Then Angle A will have a measure of 7x - 15 or 7• 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle b will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
NOTE: 139 + 41 = 180

A theater owner wants to provide enough seating for 786 people. The main floor has 24 rows of 20 seats in each row. If the balcony has 17 rows, how many seats must be in each row to satisfy the owner's seating requirements?
Answer:
18
Step-by-step explanation:
24 x 20 = 480 (amount of seats on main floor)
786 - 480 = 306 (amount of seats needed on balcony)
306 ÷ 17 = 18 (amount of seats on each row of balcony)
Step-by-step explanation:
The main floor has 24*20 = 480 seats.
So you need 786- 480 = 306 more seats
There are 17 rows in the balcony and let's say there are x seats in each row. Since you need 323 seats, this means
19x = 323
x = 306/17
x = 18
So there must be 18 seats in each row up in the balcony.
