<h3>Answer: 8 pairs of perpendicular lines</h3>

===============================================

The 8 perpendicular pairs of lines are:

AB and BC
BC and CD
CD and DE
DE and EF
EF and FG
FG and GH
GH and HA
HA and AB

I started with AB and worked counterclockwise around the figure so that I could methodically list each pair of perpendicular lines. Perpendicular lines always form a 90 degree angle. While the square angle markers aren't there, I'm assuming your teacher meant to put them in.

Alternatively, you can count the number of right angles and you'll also get 8 as the answer.

A weather report said there is a 60% chance of rain on Monday, and a 30% chance of rain on Tuesday. Based on the report, what is

sergey [27]

Answer:

The answer is 18 percent, or 9/50.

Step-by-step explanation:

We first convert the chance of rain on Monday into a fraction.

60%=60/100=3/5.

We then convert the chance of rain on Tuesday into a fraction.

30%=30/100=3/10.

Because the two events are independent(i.e. If it rains on Tuesday doesn't depend on if it rains on Monday) we multiply them together to get the probability they both happen. That chance is:

3/5 * 3/10=(3*3)/(5*10)=9/50(fraction form)=18/100=18%(percent form)
