Answer:
24 hours
Step-by-step explanation:
Let x represent the time required to fill both pipes if they are left open
1/6 + (-1/8)= 1/x
1/6 - 1/8= 1/x
Divide through by 48
48(1/6) -48(1/8) = 48(1/x)
8 - 6 = 48 x
2= 48/x
2x= 48
x= 48/2
x= 24
Hence it will take 24 hours to fill the pipe if the drain is left open

Write a function rule. Then find the value of y for the given value of x.
y is 4 more than the product of 7 and x; x = 3
Answer:
25
Step-by-step explanation:
x = 3
according to the condition,
y = 7× x + 4
y = 7× 3 +4
y = 21 + 4
y = 25

(4 pts.)
What is the price of one CD? One DVD?
Answer:
I know Dave's one is 13.04$ Just to get you started.
Step-by-step explanation:
If you divide Dave's one, which is 67 by 5, you get 13.05.
Do the same with Joyce's.

The college tutoring center staff are considering whether the center should increase the number of math workshops they offer to help students improve their performance in math classes. Faculty would like to know if requiring student attendance at these math workshops will improve overall passing rates for their students in their math classes. They plan to use the number of workshops attended to predict the final exam score and regression analysis to determine the effectiveness of the mandatory workshop attendance policy.
For each of the following classify the variable as explanatory, response, or neither.
a. Whether the student attended a workshop.
b. Number of workshops attended
c. Whether the student passes the course
Answer:
a. Whether the student attended a workshop. Neither
b. Number of workshops attended. Explanatory variable
c. Whether the student passes the course. Response variable
Step-by-step explanation:
In a given experiment, the response variable addresses the core of the question that was asked. In the experiment above, we are trying to determine the passing rate. That is the response variable. The explanatory variable provides an explanation for the response.
The number of workshops attended by the students would provide an explanation of their passing rates. Whether the student attended a workshop is not a consideration in the experiment, because it is believed that they would attend the workshop.
The distance between two points is √39 One endpoint is (4,−3). It is known that the y-coordinate of the other endpoint is 2.
What is the x-coordinate of this endpoint?
Answer:
[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]
Step-by-step explanation:
We have the two points: (4, -3) and (x, 2).
We know that the distance between them is √39.
To find our x-coordinate of the second point, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Let (4, -3) be (x₁, y₁) and let (x, 2) be (x₂, y₂). We also know that the distance d is √39. Substitute:
[tex]\sqrt{39}=\sqrt{(x-4)^2+(2-(-3))^2[/tex]
Solve for x. First, let's square both sides. This cancels out the square roots:
[tex]39=(x-4)^2+(2+3)^2[/tex]
Evaluate the second term on the right:
[tex]39=(x-4)^2+(5)^2[/tex]
Square:
[tex]39=(x-4)^2+25[/tex]
Subtract 25 from both sides:
[tex]14=(x-4)^2[/tex]
Take the square root of both sides. Since we're taking an even root, we need plus/minus. So:
[tex]x-4=\pm\sqrt{14}[/tex]
Add 4 to both sides:
[tex]x=4\pm\sqrt{14}[/tex]
Therefore, there exists two possibilities for our second point. It can either be:
[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]
And we're done!

a car rental service charges customers for the number of miles they travel rounded to the nearest whole mile George travels 40.8 miles how many miles will he be charged explain
Answer:
41 miles
Step-by-step explanation:
the company is saying they will round the number of miles, and charge you that number
when rounding 40.8, you round up to 41
1,2,3,4 rounds down to 0
5,6,7,8,9 rounds up to the next 0 up
The required miles he will be charged for is 41 miles.
Given that,
A car rental service charges customers for the number of miles they travel rounded to the nearest whole mile George travels 40.8 miles
To determine how many miles will he be charged.
The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.
Here,
The customer traveled for 40.8 miles,
Now round it to the nearest whole miles, Since 40.8 where 0.8 is 0.2 near to the 1 so the round of 40.8 become 40.8 + 0.2 = 41
Thus, The required miles he will be charged for is 41 miles.

If the sum of three consecutive numbers is 1998, what is the first one?
Answer: 665
Step-by-step explanation: X + X + 1 + X + 2 = 1998
3X + 3 = 1998
3X + 3 - 3 = 1998 - 3
3X = 1995
3X/3 = 1995/3
X = 665

3) You paid $5 for a bucket of popcorn and $1.25 per candy bar. How many candy bars
can you buy to spend no more than $10?
4 dollars flat $4.00
Step-by-step explanation:
1.25x4= 5$ 5$+5$=10$
Answer:
4 candy bars
Step-by-step explanation:
you have to subtract $5 from $10, which is $5, then take the .25 from the candy bar. Add $4 candy bars to $5, $9, and then add in the .25. .25 times 4 is $1, and $9+$1 is $10
