Answer:
A
Step-by-step explanation:
30/.5 = 60
60 + 10 = 70
First off change everything to minutes. The 600 is irrelevant in this problem. He can mow this size in 80 minutes. 8 hours is 8x60= 480. 480/80 is 6 and therefore he can mow 6 lawns in this size in time of 8 hours
answer: Rolling Two Dice. Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.
Step-by-step explanation: hopefully this is right
Answer:
M(-4, -1)
Step-by-step explanation:
M = (A +B)/2
M = ((-7, 2) +(-1, -4))/2 = (-8, -2)/2 = (-4, -1)
The location of M is (-4, -1).
The first step to solve this problem is to convert the first mixed number to an improper fraction.
