Answer:
current speed = 12 mph
Step-by-step explanation:
distance / rate = time
time upstream + time downstream = 26
25 / (13-c) + 25 / (13+c) = 26 ( c = current speed)
solve for c = 12 mi/hr
Answer:
Step-by-step explanation:
it's 12 by 10, 12 x 10 = 120. because it's a triangle, you divide 120 by 2.
120 / 2 = 60. therefore the area of the triangle is 60. I also don't know the unit im supposed to use. is it centimeters? inches? miles?
Answer:
A
B
E
Step-by-step explanation:
If you find what 11 squared is: 121
All number greater than or equal to 121 will be solutions.
he magician starts with the birthday boy and moves clockwise, passing out 100100100100 pieces of paper numbered 1111 through 100100100100. He cycles around the circle until all the pieces are distributed. He then uses a random number generator to pick an integer 1111 through 100100100100, and chooses the volunteer with that number.
Method2: The magician starts with the birthday boy and moves counter-clockwise, passing out 75757575 pieces of paper numbered 1111 through 75757575. He cycles around the circle until all the pieces are distributed. He then uses a random number generator to pick an integer 1111 through 75757575, and chooses the volunteer with that number.
Method 3\: The magician starts with the birthday boy and moves clockwise, passing out 30303030 pieces of paper numbered 1111 through 30303030. He cycles around the circle until all the pieces are distributed. He gives #1111 to the birthday boy, #2222 to the next kid, and so on. He then counts the number of windows in the room and chooses the volunteer with that number.
yes probabilites can be used to make fair ones
