WILL MARK AS BRAINIEST!Jill has a hot tub that holds 1,260 gallons of water. She needs to drain the hot tub, so that it can be moved to a new location in her backyard. If draining the hot tub is modeled by the equation y = -793/2 x + 1,260, how long will it take to drain the hot tub?
A) 2 hours 48 minutes
B) 2 hours 59 minutes
C) 3 hours 11 minutes
D) 3 hours 22 minutes
Answers
Answer:
C) 3 hours 11 minutes
Step-by-step explanation:
We are given that Jill has a hot tub that holds 1,260 gallons of water.
Draining the hot tub is modeled by the equation :
Now we are asked to find how long will it take to drain the hot tub
So, substitute y = 0 in equation :
So, it will take 3.17780580076 hours
Now 1 hour = 60 minutes
So, 0.17780580076 hours =
= minutes
≈ 11 minutes
So, it will take 3 hours and 11 minutes
Hence it will take 3 hours and 11 minutes to drain the hot tub .

We have to match each of the words to it's definition:
- Additive inverse-- the opposite or negative of a number; the sum of a number and its additive inverse is zero
( Since we know that for any real number a the additive inverse of the number is " -a " )
- Integer-- a number belonging to the set made up of the whole numbers and their opposites.
( We know that the integers are the numbers of the form {.....-4,-3,-2,-1,0,1,2,3,4,.....} )
- Irrational number -- a number that cannot be written as a ratio of two integers, which has an infinite decimal representation that does not repeat
( We know that irrational number is an opposite of a rational number
Hence, it could not be written in the form of p/q where p and q are integers and q≠0]
also the decimal expansion of such a number is non-recurring and non-repeating )
- Natural number -- a number belonging to the set made up of the numbers that are used to count: 1, 2, 3, and so on .
( These are the numbers which are used to count)
- Rational number -- a number that can be written as a ratio of two integers in the form a/b with b ≠ 0
- Whole number -- a number belonging to the set made up of zero and the natural numbers.

If Katherine is 9, and Joel is 3, 20 years later they'll be 29 and 23. Katherine is 6 years older than him.
k + 20 = 6 + (j + 20) => k = 6 + j; but k =3*j => 3*j = 6 + j => j = 3( Joel has 3 years) and k = 9 (Katherine has 9 years);

Answers
Answer:
Step-by-step explanation:
Given
ID Card of 5 digits
Possibly Digits = {0,1...,9}
Required
Probability that a card has exact number 94213
First, we have o determine the total possible number of ID card numbers
Let the card number be represented by ABCDE
Given that repetition of digits is not allowed;
A can be any of 10 digits
B can any of the remaining 9 digits
C can be any of the remaining 8 digits
D can be any of the remaining 7 digits
E can be any of the remaining 6 digits
Total number of cards = 10 * 9 *8 * 7 * 6
Total = 30240
Provided that the card number is generated at random; each card number has the same probability of
Hence, the probability of having 94213 is
