Which graph has a rate of change of zero?
Answer:
The second (bottom) graphStep-by-step explanation:
The first line is:
x = 3It has undefined rate of change
The second line is:
y = 3It has rate of change of zero (no change in y-value for any x-value)
Answer:
The first graph is : x=3Here, the rate of change is not defined.
The second graph : y=3Here, the rate of change is zero .i.e., y is independent of x.
Therefore, 2nd graph has a rate of change of zero.
On their most recent 8-mile training run, Pepe averaged a speed of
I of a mile in 4.5 minutes, while Paula averaged of a mile in 7.5
minutes.
How many minutes did it take the faster runner to finish the 8 mile
run?
Answer:
36 minutes
Step-by-step explanation:
Given that:
The length of run = 8 miles
Average speed of Pepe = 4.5 minutes per minute
Average speed of Paula = 7.5 minutes per minute
To find:
Minutes taken by the faster runner to finish the 8 mile run?
Solution:
First of all, let us have a look at the relation between Time and Speed.
[tex]Speed = \dfrac{Distance}{Time}[/tex]
If the distance is a constant, then
[tex]Speed \propto \dfrac{1}{Time}[/tex]
i.e. Speed is inversely proportional to time.
That means faster runner will take smaller amount of time.
So, faster runner is Pepe who is taking lesser time.
Time taken to complete 1 mile = 4.5 minutes
Time taken to complete 8 miles = 4.5 [tex]\times[/tex] 8 minutes = 36 minutes
So, the faster runner i.e. Pepe takes 36 minutes.
Simplify. Assume that all variables are positive.
Answer: [tex]-3x^{2} y\sqrt[3]{2y}[/tex]

Answer:
C) 19
Step-by-step explanation:
The two angles next to each other are complementary angles meaning they add up to 90°. We can use this information to solve for y:
3y + 2 + 31 = 90
3y + 33 = 90
3y = 57
y = 19

Diet cola was on sale last week; it cost $10 for every 4 packs of cola. How much do 2 packs of cola cost?
Answer:
2 pack of cola would cost $5.
Step-by-step explanation:
the reason for this being is that
4 packs of cola = $10
2 is half of 4
5 is half of 10
$5<====
Answer:
I would say 5$
Step-by-step explanation:
You are going from 4 packs to 2 packs (so you are dividing by 2). So if you divide 10$ by 2 you get 5$

A painting is 23 inches high and 11 inches wide. What is the diagonal length across the painting?
Answer:
the diagonal length is 25.50
Step-by-step explanation:
The computation of the diagonal length across the painting is as follows:
As we know know that
The Diagonal length would be
= [tex]\sqrt{w^2 + l^2}[/tex]
where
w = width
l = length
So, the diagonal length is
[tex]= \sqrt{23^2 + 11^2}\\\\= \sqrt{529 }+ 121} \\\\= \sqrt{650}[/tex]
Hence, the diagonal length is 25.50

You roll a 6-sided die.
What is P(not factor of 35)?
Simplify your answer and write it as a fraction or whole number.
Answer:
[tex]\huge\boxed{\text{P(not factor of 35) = } \frac{2}{3}}[/tex]
Step-by-step explanation:
We can use basic probability to find the probability that this roll is not a factor of 35.
First off, we know that with a six sided die there are 6 possible things we can roll.
1, 2, 3, 4, 5, or 6
Now, what are the factors of 35? The factors of 35 will be any whole number that can be multiplied by another whole number to get 35.
We know [tex]1 \cdot 35 = 35[/tex], so two factors are 1 and 35.We know [tex]5 \cdot 7 = 35[/tex], so two factors are 5 and 7.Therefore, the factors of 35 are 1, 5, 7, 35.
Both 5 and 7 are inside the range of 1-6. So the probability of rolling a side that's a factor of 35 will be [tex]\frac{2}{6} = \frac{1}{3}[/tex] since there are two factors and 6 possible options.
This means, logically, there is a [tex]\frac{4}{6} = \frac{2}{3}[/tex] chance of not rolling a factor of 35.
Hope this helped!

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Paul has scored 75, 80, and 91 on the first three. What range of scores on the fourth test will give Paul a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Answer:
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
Step-by-step explanation:
The average is given by the sum of all scores divided by the number of scores.
In this question:
Sum of all scores: 75 + 80 + 91 + x = 246 + x
Number of tests : 4
Grade of 70:
[tex]\frac{246 + x}{4} = 70[/tex]
[tex]246 + x = 280[/tex]
[tex]x = 280 - 246[/tex]
[tex]x = 34[/tex]
Grade of 79:
[tex]\frac{246 + x}{4} = 79[/tex]
[tex]246 + x = 316[/tex]
[tex]x = 316 - 246[/tex]
[tex]x = 70[/tex]
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.

Find the value in f each variable
Answer:
x=63°, y=47°, w=70°, z=121°
Step-by-step explanation:
Angles in a Triangle
To find the value of the variables given in the figure, we must recall some properties of the angles in a triangle and in a line:
The sum of all interior angles in a triangle is 180°The sum of all exterior angles in a triangle is 360°Two adjacent angles formed by the intersection of two lines add up to 180° (linear angles)The exterior angles of the triangle have the measures z-13, z, and z+10. They must add up to 360°, thus:
z - 13 + z + z + 10 = 360
Simplifying:
3z - 3 = 360
Adding 3:
3z = 360 + 3 = 363
z = 363/3
z = 121°
Now we use the bottom left vertex of the triangle, where the angles z-13 and w must add up to 180° because they are linear angles:
z - 13 + w = 180
Since z=123°
123 - 13 + w = 180
Rearranging:
w = 180 - 123 + 13
w = 70°
Similarly angles y and z+10 are linear, thus
y + z + 10 = 180
y + 123 + 10 = 180
Solving:
y = 47°
Finally, the sum of the interior angles of the triangle is 180°, thus:
x + 70 + 47 = 180
x = 180 - 70 - 47
x = 63°
Solution: x=63°, y=47°, w=70°, z=121°

It costs Linus a processing fee of $45 to set up a new cell phone account with AT&T plus $65 per month for the cell phone plan. His sister, Lucy, also wants to use the cell phone to call her friends each month. Lucy agrees to pay Linus $15 towards the processing fee and tells him she will pay $20 per month.
Define a variable.
Write an expression that represents how much Linus will have to pay for the cell phone if Lucy contributes.
Determine how much Linus will pay if he has the cell phone for 6 months.
Step-by-step explanation:
Let x represent the number of months for the cell phone plan.
Since Lucy is contributing, Linus does not have to pay the full cost.
Instead Linus will have to pay:
($45 + $65x) - ($15 + $20x)
= $30 + $45x.
If x = 6,
Linus will pay $30 + $45(6) = $300.
