Answer:

5 gardeners

Step-by-step explanation:

1 gardener - 6 trees in 30 min

or 1 tree in 5 min so in one minute gardener can plant 1/5 tree

in 45 min 1 gardener can plant 9 trees

so you would need 5 gardeners to do 45 trees in 45 min

MA_775_DIABLO [31]

Answer:

1. Degree= 6, trinomial

2. degree= 4, binomial

Step-by-step explanation:

1. The largest exponent is 6 making it the degree and there are three terms because (m^5n^2), (mn^2), (n^6).

2. Since (9a^2bc^2) has the more than 1 exponent, you add them and the  degree is 4. There are two terms because (2a^3b), (9a^2bc^2).

The mechanic dose 4 oil changes in 2 hours. How many oil changes can the mechanic do in 8 hours HELLOOOO OLEASE HELP THIS IS DUE
Yuki888 [10]

Answer:

16 oil changes

Step-by-step explanation:

You can write this into ratio form to help explain this. The ratio 4:2 can be used to explain this problem with the 4 meaning 4 oil changes and the 2 meaning after every two hours. You want to make it to where the 2 hours is at 8 hours so you would multiply 4 on both sides of the ratio which will give you the new ratio of 16:8. The mechanic can do 16 oil changes within 8 hours.
