A Boxerville Express commuter train leaves the station every 30 minutes. When Theo arrives at the station, a woman tells him she has been there for 10 minutes and that she just missed the last train. If the variable T stands for the amount of time Theo will have to wait, which of the following choices is the most reasonable value for T?

A. 5 minutes

B. 20 minutes

B: 20 minutes

Step-by-step explanation:

Because it comes every 30 minutes and he is 10 minutes late we do

30-10=20

Therefore he has to wait 20 minutes for the next train.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
