Answer:

25

Step-by-step explanation:

We'll compare it with the study of sets, the most noticeable operation of which is:

where,

n(A ∪ B) is the Union Set, i. e, the set that contains all the elements

n(A) is a subset of the Union Set

n(B) is another subset of the Union Set, and

n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.

Let set A contains the students who play basketball and set B, the students who play Volleyball.

10 students play both of them, i. e.,

Using the above operation:

=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

=> n(A ∪ B) = 25 + 20 - 10

=> n(A ∪ B) = 35

The total number of students in the class

= students into the given sports + students who don't play any of them

The students who play neither = 60 - 35

= 25

Answer:

x=17.

Step-by-step explanation:

1) the unknown inside third angle of the triangle is: 180-(8x-11);

2) the sum of all the angles in the triange is 180, it can be written:

180-(8x-11)+5x+(2x+6)=180;

3) the required value of x is: 17

Answer:

6

Step-by-step explanation:

Using a system of equations, the amount of solution a and b required to make the required gallons of the solution are 29.41 and 20.59 respectively.

Let :

a + b = 50 - - - - (1)

0.24a + 0.41b = 50 × 0.31

0.24a + 0.41b = 15.5 - - - - (2)

From (1) :

a = 50 - b - - - - (3)

Substituting (3) into (2)

0.24(50 - b) + 0.41b = 15.5

12 - 0.24b + 0.41b = 15.5

0.17b = 15.5 - 12

0.17b = 3.5

b = 20.588

From (3) :

a = 50 - 20.588

a = 29.412

Therefore, about 29.41 gallons of solution a and 20.59 gallons of solution b is required.

Answer:

2 [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

First, we will turn 5 2/5 into an improper fraction:

5 * 5 = 25 + 2 = 27/5

So they worked for 27/5 days.

We want to divide the days worked by the distance to get the unit rate of distance per day:

[tex]\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}[/tex]

So our answer is 2 [tex]\frac{2}{9}[/tex]

Answer:

≈3.14

Step-by-step explanation:

The formula for finding the area of a circle is:

π·r²

π=approximately 3.14(pi)

r=radius

If you follow this formula,

you would multiply 3.14 by 2², which is basically 2x2.

2x2=4   3.14x4=12.56

But since pi is an irrational number that goes on forever, you usually round pi to the hundredths place, which would be 3.14. But since you're finding the area of 1/4 circle, you need to divide the answer by 4. 12.56/4=3.14, so the answer is about 3.14.

Answer:

35

Step-by-step explanation:

It is easiest to find the full number if you find just 1/7 first. We know that we have 3/7 in total, so divide the number, 15, by 3 to get 1/7 of the total number. This gives 5. Therefore, 5 is 1/7 of the total. Thus, to find the total, simply multiply 5 by 7. This gives the total 7/7, 35.

Answer:

Reflections are mirror images over what they are being reflected off.

Think of your own reflection in the mirror. It's not exact, like pictures is it? You could also think of it as folding a piece of paper that has wet paint on it in half. The painted image transfers to the other side of the paper, but it's not exactly the same as the original.

I don't know how exactly to explain it, but that is how I think of it.
