Andre sometimes mows on the weekend to make extra money. two weeks ago, he mowed a neighbor's lawn for 1/2 hour and earned $10. last week, he mowed his uncles lawn for 3/2 hours and earned $30. this week, he mowed the lawn of a community center for 2 hours and earned $30. which job paid better than others?

Andre got better paid when he mowed for neighbor's and uncle's lawn which is $20/hr than Community center's lawn which is $15/hr.

Step-by-step explanation:

Given:

Andre mowed a neighbor's lawn for 1/2 hour and earned $10.

For 1/2 hour = $10

So for 1 hour = Money earned in 1 hour.

By using Unitary method we get;

Money earned in 1 hour =

Hence Andre hourly rate to mowed neighbor's lawn is $20.

Also Given:

Andre mowed a Uncle's lawn for 3/2 hour and earned $30.

For 3/2 hour = $30

So for 1 hour = Money earned in 1 hour.

By using Unitary method we get;

Money earned in 1 hour =

Hence Andre hourly rate to mowed Uncle's lawn is $20.

Also Given:

Andre mowed Community center's lawn for 2 hour and earned $30.

For 2 hour = $30

So for 1 hour = Money earned in 1 hour.

By using Unitary method we get;

Money earned in 1 hour =

Hence Andre hourly rate to mowed Community Center's lawn is $15.

Now Since we can see that when he mowed neighbor and uncle's lawn he was paid at rate of $20 and when he mowed Community Center's lawn he got paid at rate of $15.

Hence Andre got better paid when he mowed for neighbor's and uncle's lawn which is $20/hr than Community center's lawn which is $15/hr.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
