Answer:
40 gallons
Step-by-step explanation:
Let the number of gallons that would completely fill the bathtub be represented by N.
Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;
30% of N = 12
x N = 12
30N = 12 x 100
30N = 1200
divide both sides by 30,
N = 
= 40
The number of gallons that would completely fill the bathtub is 40 gallons.
Answer:

+ 4p + 3
Step-by-step explanation:
I am having a little trouble reading the number. I think 5 is the question number and not part of the problem. I think this is the problem:
(4p - 6
- 3) - (8
+ 7
- 6) You take the opposite of everything inside the second set of parentheses. You can think of it as multiplying through by -1
4p - 6
- 3 - 8
- 7
+ 6 Now we combine like terms. That is the numbers with the same variable p and the same power of p.
-13
- 8
+ 4p + 3

Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
Answer:
2
Step-by-step explanation:
We are given that Ticket writing on campus follows a Poisson process.
Last year the campus police wrote 1460 tickets
So, 
1 year = 365 days
So, E(Y) =
So, the standard deviation of the number of tickets written per day by the campus police = 
Hence the standard deviation of the number of tickets written per day by the campus police is 2
seven ones and 6 hundredths
