The freezing point of water in degrees Celsius is 0 while in degrees Fahrenheit it is 32. The boiling point of water is 100 degrees Celsius and 212 degrees Fahrenheit. Given that the function F is linear, use this information to find an equation for F
The function F to be used to convert the temperature is; F = ⁹/₅C + 32
How to Solve Algebra Word Problems?
From the given information, we can tag the coordinates as;
(32,0) and (212,100)
Thus, the slope is calculated as;
m = (100-0)/(212-32)
m = 100/180
m = 5/9
The intercept is;
c = y - mx
c = 0 - (5/9)(32)
c = 0 - 160/9
c = -160/9
The line equation is;
y = 5/9 x + (-160/9)
y = 5/9 x - 160/9
y = 5/9 (x - 32)
Let x = F and y = C and we have;
F = ⁹/₅C + 32

Find the measure of the missing angles.
62°
b\co
The measures of angles B and C are 118° and 62°, respectively.
What are the measures of two missing angles generated by the intersection of two lines?
A system of three angles is generated by two lines intersecting each other. In accordance with Euclidean geometry, angle C is opposite to the angle with measure 62° and angle B is supplementary to the same angle.
When two angles are opposite, then both have the same measure, and when two angles are supplementary, then the sum of their measures equals 180°. Therefore, the measures of angles B and C are 118° and 62°, respectively.

The Yankees won 95 games in 2010 and 97 games in 2011. What is the percent change in the number of wins from 2010 to 2011?
Please answer
The percentage change is 2.1%
How to calculate the percentage change ?The Yankees won 95 games in 2010
They also won 97 games in 2011
Therefore the percentage change can be calculated as follows
= 97 - 95/97 × 100
= 2/97 × 100
= 0.021 × 100
= 2.1
Hence the percentage change is 2.1%

The individuals of a set are the various data or variable of a data set.
The study's participants or study subjects are referred to as individuals. The trait of the person being measured or observed is known as a variable. For instance, if we were to do a research on climbers of Mount Everest, the participants would be the real climbers who succeeded in reaching the summit.
A categorical variable places each individual in to a category such as male or female.
A quantitative variable has numerical values that measure some characteristic of each individual, such as height in centimeter or salary in dollars.
The problem deals with the concept of types of variables. We use the definition of variables to identify/determine the type variable from the known information.

A is between c and t. if ct = 25 and at = 18, what is the length of segment ca?
The length of the segment CA is 7.
Length of the segment
Basically, length of the line segment is fixed, which is the distance between two fixed points.
The length here can be measured by metric units such as centimeters (cm), millimeters (mm) or by conventional units like feet or inches.
Given,
A is lies between C and T.
Then the values of CT = 25 and AT = 18.
Now we have to find the length of the segment CA.
Consider the point C, A and T are in straight line.
Then A lies between C and T.
So, it is the center point between C and T.
Here we have the length of total line that is
=> CT = 25.
And the length of AT, that is
=> AT = 18.
Then we need to find the length of the segment CA,
By subtracting the length of AT from the total length CT,
That is,
=> CA = CT - AT
Apply the values,
=> CA = 25 - 18
=> CA = 7.
Therefore, the length of the segment CA is 7.

31. What is the formula for the perimeter of a square with the side s
and a perimeter p?
Answer: p = 4s
Step-by-step explanation:
The perimeter is the measurement around a shape's sides. In other words, if a square has four sides, we will add up all the sides to find the perimeter.
Since a square's sides are all congruent, we can multiply the length of one side (s) by 4 to find the total perimeter (p). This becomes:
p = 4s

Step-by-step explanation:
I assume these are all angles.
4x is the arc angle (at the center of the circle) between the 2 endpoints of the short triangle side (baseline).
the trials itself is isoceles, so both legs have the same length, bedclothes the arc angles between their endpoints are equal.
now, when we move the reference point of an arc angle back, back, back to the circle arc, the angle is cut in half.
so, the inner top angle of the triangle is therefore 4x/2 = 2x.
because of the isoceles nature, the second triangle inner angle at the baseline is also x.
the sum of the triangle angles is therefore
2x + x + x = 4x
and we know the sum of all angles in a triangle is always 180°.
so,
4x = 180
x = 180/4 = 45°
4x is then again 180°, and 2× 8y are then the remaining 180° of the full circle 360°.
2× 8y = 180
8y = 90
y = 90/8 = 11.25
x = 45
y = 11.25

how many mg of vitamin c does tomato juice have per serving?
A marathon is 26.2 miles. How many hours would it take a runner whose average speed is 4.25 meters/sec to complete a marathon?
Given the distance and average speed, the runner will take approximately 2.76 hours to complete the marathon.
How long will it take the runner to complete the marathon?
Speed is simply distance traveled per unit time.
Speed = distance / time
Given the data in the question;
Distance = 26.2 milesSpeed = 4.25m/sTime t = ?First, convert the unit of distance from miles to meter.
Distance = 26.2 miles = ( 26.2 × 1609.34 )m = 42164.708m
Now, plug the values into the equation and solve for time.
Speed = distance / time
4.25m/s = 42164.708m / time
Time = 42164.708m ÷ 4.25m/s
Time = 9921.1077647s
Next, convert to hours,
Time = 9921.1077647 ÷ ( 60 × 60 )
Time = 9921.1077647 ÷ 3600
Time = 2.76 hours
Given the distance and average speed, the runner will take approximately 2.76 hours to complete the marathon.

Fahrenheit. During that time, the temperature rose, stayed steady, and fell, at
different rates. On the set of axes below, Hunter created a graph of temperature over time.
How long did the temperature hold steady for??
For 6 hours the temperature is held steady
Solution :
Line Graph:
A line graph—also known as a line plot or a line chart—is a graph that uses lines to connect individual data points. A line graph displays quantitative values over a specified time interval. In finance, line graphs are commonly used to depict the historical price action of an asset or security.
Line graphs can be compared with other visualizations of data including bar charts, pie charts, and (in trading) candlestick charts, among others
Temperature Rose:
It is the increase over ambient temperature of the winding due to energizing and loading
stayed steady:
A steady situation continues or develops gradually without any interruptions and is not likely to change quickly.
Temperature fall :
Temperature drop (T1−T2) is a direct indication of energy extracted. For a given resource, it is dependent on T2 which is in turn dependent on the minimum temperature of the process Ti.
There, we can see that the temperature between 12 noon to 6 pm is not changed much.
therefore we can say that for 6 hours the temperature is holding steady.
