If n lines are drawn in a plane, how many regions do they separate the plane into? induction

grandymaker [24]

Hello,

Let's assume i the number of lines,
u(i) the number of regions:

$u_0=1\\\\
u_1=2=1+1=1+u_0\\\\
u_2=4=2+u_1\\\\
u_3=7=3+u_2\\\\
u_4=11=4+u_3\\\\
u_5=16=5+u_4\\\\
...\\\\
\boxed{u_{n+1}=(n+1)+u_{n}}\\\\

u_{n+1}=(n+1)+n+(n-1)+...+1+u_0\\\\

\boxed{u_{n+1}= \dfrac{(n+1)*(n+2)}{2}+1 }$

Of the 1200 people who attended the Friday night football game, 57% were high schoolers. How many students attended the game?

Brilliant_brown [7]

Answer:

684

Step-by-step explanation:

Using proportions (equivalent ratios), we can find the number of students that make up the 57% out of the total number of people:

$\frac{57}{100}=\frac{x}{1200}$

Cross-multiply: 100x = (57)(1200) or 100x = 68,400

Divide: 100x/100 = 68,400/100

Solve for x: x = 684 students

42 liters of juice were evenly

I am Lyosha [343]

Answer: 42/6=7

Step-by-step explanation:

there's 42 liters of juice right? so to <u>divide</u> it into six batches all you got to do is divide all the liters of juice into how many batches you need. So as it says in the question, just divide 42 by 6 and you'll get your answer which is 7.
