2.4⋅(−3.4)⋅(−1.25)=−3.4⋅2.4⋅(−1.25) 2.4⋅(−3.4)⋅(−1.25)=−3.4⋅2.4⋅(−1.25) (42⋅3.5)+(42⋅1.3)+(42⋅5.2)=42⋅(3.5+1.3+5.2) (42⋅3.5)+(42⋅1.3)+(42⋅5.2)=42⋅(3.5+1.3+5.2) −2.5⋅(4⋅3.67)=(−2.5⋅4)⋅3.67 −2.5⋅(4⋅3.67)=(−2.5⋅4)⋅3.67 −3⋅(6.48)=(−3⋅6)+(−3⋅0.4)+(−3⋅0.08) −3⋅(6.48)=(−3⋅6)+(−3⋅0.4)+(−3⋅0.08) All of them
Luke: 2 miles in 40 minutes, 20 minutes a mile, (2/40 = 20 minutes a mile)
Luke's speed is 3 miles an hour (60minutes/20minutes a mile = 3miles).
Sally: 0.05 miles a minute, 60 minutes in an hour, 60 x 0.05 = 3 miles an hour. Or 0.05 miles a minute, 40 minutes walked, 40 x 0.05 = 2 miles walked.
There are a few other ways to show that they are accurate rates.
So yes, they are both correct rates.
Answer:
30%
Step-by-step explanation:
Method 1-
Divide 9 by 9/30. You get 30. This is the percent that you need!
Method 2-
You can also simplify 9/30 down to 3/10. You just multiply this by 10 on both sides. This makes 30/100, or 30%
