If a filter can process 10 gallons of water per minute, then how many gallons of water can it process in one day

1 answer:

8 0

I don't know if this will be correct, but let me explain what I think, so a day has 24 hours so multiply 10 * 24 and your answer should be 240.

A university offers 3 calculus classes: Math 2A, 2B and 2C. In both parts, you are given data about a group of students who have

ankoles [38]

Answer:

4 students

Step-by-step explanation:

The total number of students is given by:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N$

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N\\51+80+70-15-20-13 + |A\cap B \cap C| = 157\\ |A\cap B \cap C| =4$

4 students in Group A have taken all three classes.

*The number of students that have taken two classes has be subtracted so those students do not get counted twice

Do a and b have the same value in the equations 2(a-1.1)=5.8 and 5/2b-2 3/4=7 1/4

luda_lava [24]

Answer:

Step-by-step explanation:

Solve each equation and compare the solutions

2(a - 1.1) = 5.8
a - 1.1 = 5.8/2
a - 1.1 = 2.9
a = 2.9 + 1.1
a = 4

(5/2)b - 2 3/4 = 7 1/4
2.5b = 7 1/4 + 2 3/4
2.5b = 10
b = 10/2.5
b = 4

Both a and b have same value

What do you know about the slopes of lines that are parallel? Explain

Rudiy27

Parallel lines have to have the same slope. The must stay the same distance apart at all times to be parallel and the only way to do that is to change in exactly the same manner as they move so slope is the change in x over the change in y. it must be the same
