Answer: 6
Step-by-step explanation: as we already know, 45 is half of 90. So that means he is mowing 2 lawns in an hour. So in 6 hours he mows twice the amount.
I think they use experimental probabilities because experiment probabilities are WAY reliable than theoretical probability
Answer:
5 1/2
Step-by-step explanation:
Let's convert all the mixed fractions to complex fractions.
6/12 + 3/12 + 4/12 + 20/12 + 33/12
Add the fractions together
66/12
How many 12's go into 66?
5 12's go into 66.
5 6/12
Simplify
5 1/2
The ratio in which Adm, Ming and Clinton sold sandwiches = 4:7:3
Number of sandwiches sold by Ming = 91
Let us assume the common ratio to be = x
Then
7x = 91
x = 91/7
= 13
Then
The number of sandwiches sold by Adm = 4 * 13
= 52
The number of sandwiches sold by Clinton = 3 * 13
= 39
So
The total number of sandwiches
sold by Adm, Ming and Clinton = 52 + 91 + 39
= 182.
So a total of 182 sandwiches were sold by Adm, Ming and Clinton.
