35 percent of the students are boys which is 259 find the total number of the students and girls
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.
y-
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 :)

The table below shows a record of three Baloon Pop games.
Number of Players
game 1 players: 52
game 1 winners: 14
game 2 players:77
game 2 winners: 25
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?
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.
[tex]\to \frac{64}{190}\\\\\to 0.33\\\\[/tex]
Calculating the Winning percentage [tex]= 0.33 \times 100= 33\%[/tex]

However, she knows only one can be correct, who is it?A.Luis states that she needs to find the area of each face, and then add them together.B.Emily states that you only need to find the area of one side and then multiply by four (the number of sides around the cube).C.Francesca states that you need to find the area of the bottom and the four sides. Since the cube is open at the top, you don’t need to include that.D.Roberto said that you need to find the area of the base and multiply by the height of the cube.

A circle has a radius of 5p6q3 cm. The area of the circle can be found using the formula A = πr2. What is the area of this circle in square centimeters?
Answer:
25p^12q^6πcm²
Step-by-step explanation:
Given the area of the circle expressed as;
A = πr^2
Given
r = 5p^6q^3 cm
Substitute into the formula
A = π(5p^6q^3 )²
A = π(25p^12q^6)
A = 25p^12q^6πcm²
hence the area of this circle in square centimeters is 25p^12q^6πcm²
The area of the circle whose radius be 5p⁶q³ is 25πp¹²q⁶ square centimeters.
What is a circle?It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circle has a radius of [tex]\rm 5 \ p^6 \ q^3[/tex] cm.
The area of the circle can be found using the formula
[tex]\rm A = \pi \ r^2[/tex]
Then the area of the circle will be
[tex]\rm A = \pi (5 \ p^6 \ q^3)^2\\\\A = \pi * 5^2 \ (P^6)^2 (q^3)^2\\\\A = 25 \ \pi \ p^{12} \ q^6[/tex]
Thus, the area of the circle is 25πp¹²q⁶ square cm.

Find the sum of 13x+5 and 8+25x.
Find a and b.........
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...
well you can follow me, for questions or further explanations.
