On a winter’s day, 9 degrees Fahrenheit is the highest temperature recorded. Write an inequality that represents the temperature t in degrees Fahrenheit at any time on this day.
Answer: The inequality that represents the temperature t in degrees Fahrenheit at any time on this day is [tex]t\leq 9[/tex] degree Fahrenheit.
Explanation:
It is given that on a winter’s day, 9 degrees Fahrenheit is the highest temperature recorded. It means the temperature on this day must be less than or equal to 9 degree Fahrenheit.
Let t represents the temperature in degrees Fahrenheit at any time on this day. Then,
[tex]t\leq 9[/tex]
Therefore, the inequality that represents the temperature t in degrees Fahrenheit at any time on this day is [tex]t\leq 9[/tex] degree Fahrenheit.
Answer:
[tex]t\leq 9^{0}F[/tex]
Step-by-step explanation:
We have been given that highest temperature recorded on a winter’s day is 9 degrees Fahrenheit and we are asked to write an inequality that represents the temperature t in degrees Fahrenheit at any time on this day.
Since we know that highest temperature can't exceed 9 degrees Fahrenheit on the given day and it will be less than or equal to 9.
Therefore, our inequality will be,[tex]t\leq 9^{0}F[/tex]

What is the slope of the line in the graph?
The slope of the line in the given graph with the coordinates (x₁ , y₁ ) = (4, 5) and (x₂ , y₂) = (2, 3) is equal to 1.
The slope of a line is calculated by rise over run.
Here is the formula for calculating the slope of a line:
Slope = (y₂ - y₁) / (x₂ - x₁)
Here, the points (x₁ , y₁ ) = (4, 5) and (x₂ , y₂) = (2, 3) are on the line. Plugging these points into the formula, we get:
Slope
= (3 - 5) / (2 - 4)
= (-2) / (-2)
= 1
Therefore, the slope of the line is 1.

to function properly, rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance. A 40 foot long rain water pipe runs under the edge of a roof. What is the vertical distance, in inches, the pipe bust drop between its ends? Round your number to the nearest tenth.
Answer: Hence, There is vertical distance of 19 inches the pipe must drop between its ends.
Step-by-step explanation:
Since we have given that
Rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance.
For 1 inch = 25 inches of vertical distance the pipe must drop.
If there is a 40 foot long rain water pipe runs under the edge of a roof.
Then, we need to find the vertical distance in inches the pope must drop.
First, we change 40 feet into inches.
Since 1 foot = 12 inches
40 feet = 40×12 inches = 480 inches
So, Vertical distance the pipe must drop is given by
[tex]\dfrac{480}{25}\\\\=19.2\ inches[/tex]
Hence, There is vertical distance of 19.2 inches ≈ 19 inches the pipe must drop between its ends.

Solve the recurrence relation for the variables indicated below: bn = 8bn-1 - 15bn-2 b1 = 2 b2 = 16 If the explicit formula for the sequence is written in the form bn = u(s1)n + v(s2)n then find s1 and s2 .
The recurrence relation is given by bn = 8bn-1 - 15bn-2 with b1 = 2 and b2 = 16.
How to depict the solution?Since it is linear homogeneous recurrence relation ,so first find its characteristic equation.
r² - 8r + 15 = 0
( r - 3 )( r - 5 ) = 0
r = 3 , 5
So, the general solution of the given recurrence relation is
bn = u(3)n + v(5)n ------------ ( 1 )
Now use the initial conditions b1 = 2 and b2 = 16.
From ( 1 ) , b1 = u(3)1 + v(5)1
2 = 3u + 5v ---------- ( 2 )
and b2 = u(3)2 + v(5)2
16 = 9u+ 25v------- ( 3 )
Solving ( 2 ) and ( 3 ) , we get u= - 1 and v = 1
Therefore, the required solution is bn = - (3)n + (5)n

The smallest number of new spools that Ted will need for this job is 8 spools of cable.
Given that, Ted is installing lighting in a new block of 12 apartments. He will need 60 metres of cable for each apartment. Each new spool holds 100 metres of cable.
We need to find the smallest number of new spools that Ted will need for this job.
What are the spools?A cylindrical device on which film, magnetic tape, thread, or other flexible materials can be wound; a reel.
Now, 60 meters per apartment x 12 apartments =720 total meters for all 12 apartments.
720 meters / 100 meters per spool =7.2 spools
so, Ted will need at least 8 spools of cable.
Therefore, the smallest number of new spools that Ted will need for this job is 8 spools of cable.

Which expression can be simplified by applying the additive inverse property
We have to identify the expression in which Additive inverse identity is applied.
Additive inverse property states that "The additive inverse of a number 'x' is a number that when it is added to 'x', yields zero".
Consider the first expression,
A. [tex] -329-164+513+206+(-164) [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
B. [tex] 1.6+0.2-1.8-0.5 [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
C. [tex] -\frac{7}{10}-\frac{3}{4}+1\frac{1}{2}+(-\frac{7}{10}) [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
D. [tex] 9\frac{3}{4}\+4\frac{5}{8}+(-9\frac{3}{4}+(2\frac{3}{5}) [/tex]
Here, [tex] 9\frac{3}{4} [/tex] when added to [tex] -9\frac{3}{4} [/tex] will yield zero. Therefore, [tex] -9\frac{3}{4} [/tex] is the additive inverse of [tex] 9\frac{3}{4} [/tex].

The price of a shirt was $38. It was reduced by 20% and then again by 10%.
a. What is the final price of the shirt?
b. What would the price of the shirt be if it were reduced by 30% from the original?
c. Explain why the two prices in a. and b. differ.
Answer:
A- The final price of the shirt was $27.36.
B- If it were reduced by 30% from the original price, the price of the shirt would be $26.6.
C- There is a difference between both prices because in the first case, the discount is split, making a first discount on a larger basis, and the second on a smaller basis, already made the first discount.
In contrast, at the second price, the entire percentage is made on the major basis. Therefore, the discount is larger.
Step-by-step explanation:
A- The final price of the shirt is determined by the following calculation:
(38 x 0.8) x 0.9 = FINAL PRICE
38 is multiplied by 0.8 because the price was reduced by 20% (0.2 is the 20% of 1, that is, of a unit. Therefore, the remaining price would be that 0.8 or 80%)
Then, using the same logic, we have to multiply that result by 0.9 in order to get the final price.
Therefore:
(38 x 0.8) x 0.9 = 30.4 x 0.9 = 27.36
B- Here, we would have to multiply 38 x 0.7, which gives a result of 26.6
