In A School Election 3/4 Of The Students Vote. There Are 1464 Ballots. Write And Solve An Equation To Find The Number Of Students

Answers

Answer 1

Answer: A simple way to turn this into an equation is by replacing the words with letters:
1464B = 3/4 S

Then you have to remove the 3/4 from the right side of the equation. You can do this by dividing both sides by 3/4:
1464 / 3/4 = S

Then you have to do the sum:
1464
/ 3
= 0488

488
X 4
= 1952

There are 1952 students.

Students sold 400 tickets to the spring band concert. The students sold adult and child (under 12 years old) tickets. Each adult ticket was $5.00 and each child ticket was $2.00. The total amount of money earned from the sale of tickets was $1475

Answers

You will have a system of equations.
Let's say that the number of adult tickets sold is x. The number of child ticket sold is y.
We know that they sold 400 tickets, so: x + y = 400
We also know that they earned $1475
An adult ticket is $5 and a child ticket is $2, so: x * 5 + y * 2 = 1475
Because x + y = 400, we know that y = 400 - x. We use this in the main equation instead of the variable y:
x * 5 + (400-x) * 2 = 1475
5x + 800 - 2x = 1475
3x + 800 = 1475
3x = 675
x = 225

Because x + y = 400, we can calculate that y = 175

They sold 225 adult tickets and 175 child tickets.

How do you model a decimal using a fraction

Answers

Okie dokie,
When converting a decimal, you use the place the decimal is in...
Let's review the places: tenths, hundredths, thousandths, etc.
You look at the last number to determine what place you're using!
-------------------
Now here's an example for the tenths place:
.5
it's in the tenths place, right? so put it over that number (with no decimal) over a 10.
(mobile) 5/10 or $(5)/(10)$
Now, decide if you can simplify. You can! 5/10 simplifies down to 1/2.
$(1)/(2)$ is your answer!
--------
Example for the hundredths place:
.26
the last number is in the hundredths place, so put the number (without a decimal) over 100!
26/100 or $(26)/(100)$
You can simplify this!
13/50 is your answer!

Calculators can also come in handy!
Good luck!

Students were asked to choose their favorite subject and, and 3/5 choose either history or biology. If 1/5 of the students choose history, what fraction choose biology?

Answers

2/5

3/5 chose either history or biology, and 1/5 chose history. If we want to find what fraction chose biology, we just subtract those who chose history for those who chose either one. 3/5 minus 1/5 is 2/5.

What is the probability that a number selected at random from the set {2, 3, 7, 12, 15, 22, 72, 108} will be divisible by both 2 and 3 ?F. 1/4
G. 3/8
H. 3/5
J. 5/8
K. 7/8

Answers

Total amount of numbers in the set = 8 .

Total amount that are divisible by both 2 and 3 = 3 .

So the probability of picking one of them is 3/8 = 37.5 percent.
