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 :)
Answer:
9
Step-by-step explanation:
area of a circle = pi times radius^2
254.34= 3.14 X r^2 get rid of 3.14 by dividing both sides by 3.14
254.34/3.14= r^2
81= r^2
find the square root of 81=9
