5h = - 8 - 7
5h = - 15
h = - 3
Answer:
Step-by-step explanation:
There is 60 min. in 1 hour. 60 ÷ 15 =4. 4×24 = 96
83 x 72 = 5,976. 82 x 73 = 5,986. The way to do this is to take the two biggest numbers and use them in the tens place. Then take the other numbers and put them in the ones space. Then switch the ones slot numbers around to get two different numbers over 5000.
Answer: At least 7
Step-by-step explanation:
A good tip is to cut the same shape and fold it and count how many symmetry :)
Urn 1 = 4 green balls and 6 blue balls, a total of 10 balls
Urn 2 = 6 green balls and 2 blue balls, a total of 8 balls.
Probability of blue balls:
Urn 1 : P = 6/10
Urn 2 : P = 2/8
Probability that both balls are blue:
6/10 * 2/8 = 6*2 / 10*8 = 12/80 = 6/40 = 3/20
Answer is B. 3/20
