This graph shows the water level in a bathtub, in inches, over time, in minutes.
After the tub started to drain, how many minutes did it take for the tub to drain completely?
Enter your answer below
? Min

Hello! I know somebody might have already answered this question, but I figured I could add more to it. In order to help you know whenever a question shows up like this again, I'll make an ordered situation for you.
Let's go ahead and make the situation!
The Situation: Let's call the person trying to figure this problem out by Alison. Alison turns on the water and allows it to run in the tub for about 9 minutes. She then turns the water off while she runs to answer the front door. She soon comes back and allows water to run into the tub for a couple more minutes before she takes a short bath. After the bath, Alison allows the water to completely drain from the tub. That's how the problem would've went, but your question.
When you're asking the question you're also trying to figure out how it would've gone. So, since you tried following the paragraph I made for the picture/problem I can show how'd it help you comprehend it better. After Alison turns on the water, turns it back off then comes back to run the water AGAIN.. She finally drains it from the tub, which is what the picture exactly shows. BUT when did she turn it off?!!!
Look at the problem, at the point where the Water level(in) starts decreasing. We know that we end with the Water level(in) at 0, but how'd it get there? The point at 12 in time is when it starts decreasing! But, from there it continues until it's at 15(min)
THE FINAL ANSWER: At 12(min) it decreases until it hits 15(min) which is when the tub is empty. So, if you do common math 15(min) - 12(min) is 3(min) So, it took 3(min) to empty the tub when it was the most full.

2.5 to the nearest tenth
Answers
Here's an example:

The 4 is in the tenth spot, so you look at the next unit over, which in this example is the 7.
To round, the key is 4 and below, don't change, 5 and above, round up.
2.478382 would round to 2.5.
Here's another example just so it's clear:
For 3.7913, the 9 would make the 7 round up and the answer would be 3.8.

Solve for n.
25n−3=5n+8
the n-3 and n+8 are powers
Answers
Final answer:
The equation 25n⁻³ = 5n⁺⁸ suggests an incorrect use of exponents, as no solution exists if we assume the bases should be the same. However, if the bases are 25 and 5, after simplifying, we find that the solution is n = 14.
Explanation:
To solve the equation 25n⁻³ = 5n⁺⁸, we need to use properties of exponents and logarithms. Here are the steps:
Assuming the bases are the same and only the exponents are different, equate the exponents: n - 3 = n + 8.This implies that no solution exists because once the bases are the same, the exponents on both sides must be equal for the equation to hold true, but here they are not.Alternatively, if 25 and 5 are the bases, we can rewrite the equation as (52)n-3 = 5n+8, then applying properties of exponents gives us 52n-6 = 5n+8. Equating the exponents yields 2n - 6 = n + 8, which we can solve for n.
Subtract n from both sides: n - 6 = 8.Add 6 to both sides to isolate n: n = 14.125 invitations to 75 invitations

What is the pattern for n times 3 plus 1

"Be excused, my dear Aunt Sally";
or other variant phrase);
__________________________________________
Using this "order of operations" rules; we know that "multiplication" comes BEFORE "addition"; as such:
_________________
Given: "n * 3 + 1"; we can write:
________________________
(n*3) + 1 ; with the parentheses as an emphasis that this "multiplication" component comes first.
___________________________________________
By convention, when a variable has a coefficient other than "1", we usually write the term with the coefficient coming before the variable.
___________________________________________
So, we can rewrite:
__________________
(n*3) + 1 ; as:
__________________
(3*n) + 1 .
__________________
By convention; if we have a coefficient multiplied by a variable (symbolized with an "alphabet letter"), we simply write that coefficent, followed by the [variable symbolized with an "alphabet letter"]. By convention, the implication is that multiplication is inherent in these circumstances.
So, "(3*n)" can be rewritten as "3n";

An “A” train leaves a subway station every 12 minutes. An “E” train leaves every 9 minutes. If both trains just left the station on parallel tracks, when will both leave the station together again?
A. in 108 minutes
B. in 36 minutes
C. in 72 minutes
D. in 24 minutes
Answers
B. In 36 minutes because 12×3=36 and 9×4=36 and this is the first number they share.
The A train and the E train will both leave the station together again in 36 minutes. Hence the correct option is B.
To find out when both the A train and the E train will leave the station together again, we need to calculate the Least Common Multiple (LCM) of their departure intervals, which are 12 minutes for the A train and 9 minutes for the E train. To find the LCM, we list multiples of each:
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108...
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108...
We can see that the common multiples of 9 and 12 are 36, 72, and 108. The smallest of these is 36 minutes, so that is the first time they will both leave the station together after initially departing at the same time.
Therefore, the correct answer is B. in 36 minutes.

find the area and perimeter of the shape below. Help plzzz.
Answers
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²

Equation: $157.30 × 10%
3. A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 10% off of their total dinner bill, not including applicable sales tax or their server’s tip. The bill totals $157.30 before tax and tip. What is the new total after the server applies the 10% off coupon?
Answers
157.30-15.73=
$141.57
this is still without the tax and tip or assuming there is none because it doesn't say how much they want to tip or weather they are planning to tip at all. It also doesn't say the percent of tax.
To find the new total after a 10% discount on a $157.30 dinner bill, you multiply $157.30 by 0.10 to get the discount amount of $15.73. Then subtract the discount from the original bill to get the new total, which is $141.57.
Explanation:To calculate the new total after applying a 10% discount to a $157.30 dinner bill, we first need to find the amount of the discount. To do this, we convert the percent to a decimal by dividing by 100. Therefore, 10% as a decimal is 0.10. Next, we multiply this decimal by the total bill amount.
$157.30 × 0.10 = $15.73
This value represents the amount of discount the family will receive. To find the new total, we simply subtract this discount from the original total bill amount.
$157.30 - $15.73 = $141.57
Thus, the new total after applying the 10% discount is $141.57.
