No @ david.

That's 2-root-2 X 2 = 4-root-2.
or 4 X 1.414 = 5.6 reh reh reh

Two ships, A and B are moving at the same speed and begin moving at the same time. Ship A is to travel from point A1 (Latitude 40N, Longitude 30E) to point A2 (40N,30W), while ship B is to travel from point B1 (40S,20W) to point B2 (40S,40E).
Which of the following is true? (Choose all that apply):
A. Ship A will arrive before Ship B
B. Ship A will arrive after Ship B
C. Ship A and Ship B will arrive at the same time.
D. Ship A and Ship B will cover equal distances.
E. Ship A will cover more distance than Ship B.

Determine the value (in degrees) of angle y
y + 80 + 40 = 180 y = 180-(80 + 40) y = 180-120 y = 60 degrees. Two ships, A and B are moving at the same speed and begin moving at the same time. Ship A is to travel from point A1 (Latitude 40N, Longitude 30E) to point A2 (40N,30W), while ship B is to travel from point B1 (40S,20W) to point B2 (40S,40E).
Which of the following is true? (Choose all that apply):
A. Ship A will arrive before Ship B
B. Ship A will arrive after Ship B
C. Ship A and Ship B will arrive at the same time.
D. Ship A and Ship B will cover equal distances.
E. Ship A will cover more distance than Ship B.
They have both covered 60(whatever the unit is). |

Yes, correct answer is 4.
yes, y is 60

y + 80 + 40 = 180 y = 180-(80 + 40) y = 180-120 y = 60 degrees. They have both covered 60(whatever the unit is). True, they both cover 60 degrees of longitude. There is one more correct option. |

They will also arrive at the same time unless either of em blows a gasket. |

If you have 3 bulbs in a room and the 3 switches are outside the room. how would you know the switch that controls what bulb? Note, you are only allowed to enter the room once.

Area of ABC is SQRT(2) times larger than area of DEF. |

Y has no value? I know the perimeter of ABC is 24 cm. I need to know at least one angle in DEF to determine the perimeter. Is it an isoceles triangle or equilateral? |

If you have 3 bulbs in a room and the 3 switches are outside the room. how would you know the switch that controls what bulb? Note, you are only allowed to enter the room once.
Label the switches: 1, 2 and 3 Switch 1: Leave it alone Switch 2: Switch it on for some time and then switch it off Switch 3: Switch it on. Enter the room: Switch 3 controls the bulb currently on Switch 2 controls the bulb that is off but warm Switch 1 controls the bulb that is off but cool |

I know the perimeter of ABC is 24 cm. I need to know at least one angle in DEF to determine the perimeter.
Is it an isoceles triangle or equilateral?
i think its an isoceles triangle. You dont need any angles in triangle DEF. Since there are two equal angles (y) then there are 2 equal sides (10). |

Label the switches: 1, 2 and 3
Switch 1: Leave it alone
Switch 2: Switch it on for some time and then switch it off
Switch 3: Switch it on.
Enter the room:
Switch 3 controls the bulb currently on
Switch 2 controls the bulb that is off but warm
Switch 1 controls the bulb that is off but cool
Correct |

Good boy. So it's 8 + 8 + 8 = 10 + 10 + 4. Good job! |

Area of ABC = 16*SQRT(3)
Area of DEF = 8*SQRT(6)

Area of ABC = 16*SQRT(3)
Area of DEF = 8*SQRT(6)
Nah. . . . . . . . Incorrect! |

Imagine a large empty bin. Say that each minute people would come and put in one golf ball a piece. The first minute (starting at 12 noon), 1 person came and put in a ball. The second minute, 2 people put in one ball a piece. A minute later, 4 people put in 1 ball a piece. This pattern continued until the bin was exactly full at 6pm. At what time was the bin half empty?
