According to the question, the model has linear relationship between the temperatures which are in degree Fahrenheit and in Celsius.
Now, to calculate the rate of change of the temperature which is defined in the ratio of y-axis and x-axis. Therefore, the expression can be written as:
Rate of change of the temperature = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
From the graph model, the coordinate values are (0,32) and (30,86)
[tex]x_{2} = 30; x_{1}=0; y_{2}=86; y_{1}=32[/tex]
Substituting the given values in the standard expression to calculate the rate of change of the temperature:
Rate of change of the temperature = [tex]\frac{86-32}{30-0}=\frac{54}{30} =\frac{9}{5}[/tex]
Hence, the rate of change of the temperature is 9/5.
What is rate of change in the graph?
In the graph, the rate of change of a quantity defines the relationship between the two quantities. The calculated values are either positive, negative or zero. It is a slope of a line in the form of ratio of vertical to horizontal axis.

determine measure of the third angle
Answer:
48°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°.
We can use this information to find the value of third angle, represented with x.
70 + 62 + x = 180 add like terms
132 + x = 180 subtract 132 from both sides
x = 48°
Suppose you pull a card from a standard 52-card deck. Find the probability of following event. The card is a 4 .
1/2 is the probability of following event. The card is a 4 .
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.In a standard 52 card deck, there are 4 categories each having 13 cards.
Spades ; Hearts ; Diamonds ; Clubs
Hearts and Diamonds are red.
No. of red cards= 13 x 2 = 26
Probability, P(r) = No. of red cards/ Total no. of cards

A tailor used 5 meters of string to make 7 Halloween masks. He used ____ of a meter for each mask.
Answer:
.715 meters
Step-by-step explanation:
Three cards are randomly chosen from a deck of 52 cards without replacement. What is the probability that they will all be red?
The probability that all three cards will be red is [tex]\frac{2}{17}[/tex]
In a deck of cards, the total number of cards is 52.
The total number of red cards in a deck is 26 i.e., half the total number of cards.
Selection of 3 cards from 52 cards is done according to 52C3.
Selection of 3 cards from 26 red cards is done according to 26C3.
∴ Probability = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
= [tex]\frac{26C3}{52C3}[/tex]
= [tex]\frac{2600}{22100}[/tex]
= [tex]\frac{2}{17}[/tex].
Hence, the probability that all three chosen cards from the deck of 52 cards will be red is [tex]\frac{2}{17}[/tex].

ilhan begin her training at 7:22 am. she crossed the finish line at 8:07 pm, after swimming 2.4 miles, cycling 112 miles and running 26.2 miles. find her average speed of the race
Ilhan's average speed in the race is 11.03 miles per hour.
What is the average speed?The average speed is a scalar measure of the total distance divided by the total time.
The average speed shows an object's displacement rate from one point to another.
Speed measures the rate of fastness, while the average speed shows the average rate of fastness of an object in movement.
The average speed is measured in magnitude without direction as a scalar quantity.
Data and Calculations:Beginning time for the race = 7:22 am
Ending time for the race = 8:07 pm
Time used = 12hours 45 minutes or 12.75 hours (8:07 pm - 7:22 am)
Distance:Swimming 2.4 miles
Cycling 112 miles
Running 26.2 mile
Total distance = 140.6 miles
Average speed = Distance/Time
= 11.03 miles per hour (140.6/12.75)

The length of a rectangle is 4 less than 5 times its width? If the perimeter of the
rectangle is 112 square feet, what is the length and width of the rectangle?
The length and width of the rectangle is 46 feet and 10 feet respectively.
Let the length of the rectangle be x and the width of the rectangle be y.
Now, the length of the rectangle is 4 less than 5 times its width.
Therefore,
x = 5y - 4
The perimeter of a rectangle is given as two times the sum of its length and breadth.
Perimeter = 2( length + breadth)
P = 2( x + y)
Now, the perimeter of the rectangle is 112 square feet.
Therefore,
112 = 2( 5y - 4 + y)
( 112 /2) = 5y - 4 + y
6y - 4 = 56
6y = 56 + 4
6y = 60
y = ( 60 / 6)
y = 10
Now,
x = 5y - 4
x = 5 × 10 - 4
x = 50 - 4
x = 46
So, the length of the rectangle is x = 46 feet and the breadth of the rectangle is y = 10 feet.

The formula for calculating the volume of a cone is V=1/3(pi)r(to the third power)h. Solve this formula for h.
The expression for the height is given as 3V/pir³
Volume of coneA cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the ape-x or vertex.
The formula for calculating the volume of a cone is expressed according to the equation;
V = 1/3pir³h
We are to make h the subject of the formula;
V = 1/3pir³h
Cross multiply
3V = pir³h
Divide both sides by pir³
3V/pir³ = pir³h/pir³
3V/pir³ = h
Swap
h = 3V/pir³
Hence the expression for the height is given as 3V/pir³

The grounds crew needs to mow the football field before their next game. Mr. Comb can mow the field in 5 hours, and Mr. Ramset can mow the same field in 4.5 hours. If they worked together, how long would it take for both of them to mow the field if they worked together? Round your answer to the nearest minute.
Answer:

Mr. Comb's rate is 1 field in 5 hours or 1/5.
Mr. Ramset's rate is 1 fiend in 4.5 hours.
If we take the time and rate that it takes Mr. Comb's to mow one field and add it to the time and rate that it takes Mr. Ramset's to move one field we can find out how long it takes them to mow one field together

9.5/22.5T = 1 We want to solve for T, so we will multiply both sides of the equation by 22.5/9.5
9.5/22.5(22.5/9.5)T= 1 22.5/9.5
