35 percent of the students are boys which is 259 find the total number of the students and girls

Answers

Answer:

740 total students, 481 total girls

Step-by-step explanation:

Let x be the total number of students and y be the total number of girls

x -

You know that 35% of the students is 259 students. If you convert this into algebra, you can write : 0.35x = 259, after simplifying, you know that x = 740.

You know that 35% of the students are boys, so 65% must be girls. You can say that 65% of x is y and write the equation 0.65(740)=y. After simplifying, you can see that y = 481.

I hope this helps :)

Find a and b.........

Answers

Answer:

a is 10

b is 37

Step-by-step explanation:

Now we must agree that the diagram above is a parallelogram.

this figure has its opposite sides parallel to each other, and also equal to each in length, this means a+5=15.

hence a is 10.

and the opposite angles of the parallelogram are equal thus, 111=3b,

hence b is 37°.

I must say I was shocked to see 111 is divisible by 3...

Number of Players
game 1 players: 52
game 1 winners: 14

game 3 players: 61
Game 4 winners: 25

Based on the data recorded in the table, how many winners would you expect if there are 100 players?

Answers

30 winners if there were 100 players

There are 33 winners which would you expect if there are 100 players, and its calculated values can be defined as follows:

Winning percentage:

[tex]\text{Number of Players } \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{ Number of Winners}[/tex]

game 1 52 14

game 2 77 25

game 3 61 25

Total 190 64

According to Heath, there have been 64 winners out of a total of 190 players.
