The formula of the set is generally written as follows.
The term set in math is defined as an organized collection of objects and can be represented in set-builder form or roster form.
Here we need to find the formula that can be used in set.
The general formula of the set can be written as follows:
=> n ( P ∪ Q ) = n(P) + n(Q) – n ( P ∩ Q)
where
n(P U Q) refers the number of elements present in one of the sets P or Q.
n(P ⋂ Q) refers the number of elements present in both the sets P & Q.
Where as If P ∩ Q = ∅, then the value is calculated as,
=> n ( P ∪ Q ) = n(P) + n(Q)
Here we have also want to know that sets P and Q are equal only if all the elements they contain intersect, and none of them have any unique elements which are not present in the other set.

decrease 784 in the ratio 3:4
Answer:
336 and 448
Step-by-step explanation:
sum the ratio
divide the actual number by the sum i.e 784÷7=122
multiply 112 by 3 and by 4
The numbers are 336 and 448 respectively.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The term "arithmetic" (which comes from the Greek word "arithmos," "number") often refers to the fundamental concepts in number theory, measurement, and computation (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
We have to decrease 784 in the ratio 3:4
Consider that after decreasing, the numbers are x and y.
From the given data:
(x / y) = (3 / 4)
⇒ 4x = 3y
⇒ y = (4x/3) ...(i)
also, x + y = 784
Substituting from eq (i)
x + (4x/3) = 784
(7x / 3) = 784
x = (743 × 3) / 7
x = 336
and y = 784 - 336 = 448
Hence, the numbers are 336 and 448 respectively.

Help please
x + 1/4 = 5/6
solve the equation for x
Answer:
x =7/12
Step-by-step explanation:
x + 1/4 = 5/6
start subtract 1/4 from both sides of the equation which will move the -1/4 to the other side to get X by itself
x=5/6 - 1/4
find common denominator, which is 12
x=10/12 - 3/12
solve by subtacting
x=7/12

Dots sells T-shirts ($5) and shorts ($8). In April, total sales were $560. People bought 4 times as many T-shirts as shorts.
Answer:
Number of T-shirts sold = 80 and number of shorts sold = 20
Step-by-step explanation:
This question is incomplete. If we have to calculate the number of shirts and T-shirts sold by Dots then we will calculate this question as below.
Let the number of shorts sold = s
And the number of T-shirts sold = T
Dots sells T-shirts at $5 and shots at $8 in April.
Equation for this situation will be,
5T + 8s = 560 -----(1)
Number of T-shirts sold are 4 times the shorts,
T = 4s ----- (2)
By substituting the value of T from equation (2) in equation (1),
5(4s) + 8s = 560
20s + 8s = 560
28s = 560
s = 20
From equation (2),
T = 4(20)
T = 80
Number of T-shirts sold = 80 and number of shorts sold = 20

Use the information below to respond to numbers 5,6,7 and 8.
Celeste was selling meal tickets for the holiday program at her school. The cost of a dinner ticket is
$10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold;
however, she remembered that she was given 100 tickets and she collected $900.
The system of equations shown can be used to represent this situation:
S x + y = 100
(10x + 6y=900
5. What does the variable x represent in the system of equations? *
1 point
O A. The number of dinner tickets sold.
O B. The number of dessert tickets sold.
O C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets.
O Other:
X is next to the number 10, so x would be the number of dinner tickets sold.
Rewrite x + y = 100 to x = 100-y
Now replace that in the 2nd equation:
10(100-y) + 6y = 900
Simplify:
1000 -10y + 6y = 900
Combine like terms:
1000 -4y = 900
Subtract 1000 from both sides
-4y = -100
Divide both sides by-4
Y = 25
Replace y in the first equation and solve for x
X + 25 = 100
X = 75
A) 75 dinner tickets were sold
B) 25 dessert tickets were sold
C) 75 x 10 = $750
D) 25 x 6 = $150

50 hundredths = ______ thousandths equals?
Answer:
50/100 = 500/1000 or alternatively .50 = .500
Answer:
500
Step-by-step explanation:
50 hundredths written in standard form is 0.50 .
**Adding zeroes to the end of a decimal does not change the value of the number.
1 hundredth = 0.01
1 thousandth = 0.001
So, if there are 50 hundredths, how many thousandths would there be?
The difference between hundredths and thousandths are the placement of the decimal point and how many decimal places there are after it. Hundredths have 2, while thousandths have 3.
Back to the example, 1 hundredth = 10 thousandths:
0.01 = 0.010
If there are 50 hundredths, that would mean that there are 10 times more thousandths in the same number.
0.50 = 0.500
50 hundredths = 500 thousandths

Set up and solve a proportion: On average, I can answer 14 out of 21 questions correctly in a trivia game. Assuming
this situation is proportional, how many MORE questions am I likely to get correct if there are 30 questions in all?
Answer:
20
Step-by-step explanation:
Since this is a ratio problem we first plug in all that we know
14:x
21:30
Now we find a way to get from 21 to 30
The ratio 14:21 can be simplified if we divide each by 7 give us 2:3
Now we plug the new ratio in
2:x
3:30
We get from 3 to 30 by multiplying by 10 so we also multiply 2 by 10 and we get 20
