Answer: 1 1/4feet
Step-by-step explanation:
From the question, we are informed that the depth of the water in the pool changes by −3/4 foot every hour and that the depth of the water was 5 feet when she started draining.
The depth of the water after 5 hours will be:
= 5 - 3/4(5)
= 5 - 15/4
= 5 - 3 3/4
= 1 1/4 feet
Group of answer choices.
A. It can be expressed as a non repeating, non terminating decimal.
B. It can be a perfect square
C. It cannot be pie π
D. It is not possible to have a irrational number solution.
Answer:
A. It can be expressed as a non repeating, non terminating decimal.
Step-by-step explanation:
An irrational number can be defined as real numbers that cannot be expressed as a simple fraction or ratio of two integers.
Additionally, it is the opposite of a rational number and as such its decimal is continuous without having any repetition or termination. For example, pie (π) = 3.14159 is an example of an irrational number.
Assuming the solution to a mathematical problem is an irrational number. The statement which is true about the solution is that it can be expressed as a non-repeating, and non-terminating decimal.

Now I feel guilty and sleezy. Giving answers alone without explanations
is something I almost never do, because it doesn't help anybody do
anything but cheat. But it's all I have time for right now. If a mod comes
along and decides to delete this because of no explanations, then let him
delete it. It'll serve us right, you and me both.
Answer:
Step-by-step explanation:
12 .x=3 y= -3
-x+2(y-1)
=-3+2(-3-1) = -3 -6 -2 = -9 -2 = -11
13.a=3
-5(a^2) -a + 5
=-5(3^2) -3 + 5 = -5(9) +2 = -45 +2 =-43
14. a = -2 b=4
-4a +3(2b-1)
= -4(-2) +3( 2(4)-1 ) =8 +3(8-1) = 8 +3(7) = 8 +21 =29
15. x = -2
3x^2 - 4x +1 =3(-2^2) -4(-2) +1 = 3(4) -4(-2) + 1 = 12 +8 +1 =20 +1 =21
