Step-by-step explanation:
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.
First, determine what 15% of $40 is.
Convert 15% to a decimal: 0.15
Then multiply this decimal by $40: 0.15 x 40 = 6
So the discount is $6.
We subtract the discount from original price to get sale price.
40-6= 34
So the item will cost $34.
Answer:
B. The mean would be higher
Step-by-step explanation:
If you add them all together, you get the number 173
Answer is 18
18 • 7 = 126
126 - 11 = 115
4 • 18 = 72
72 - 7 = 65
115 + 65 = 180
They are supplementary angles, which mean they together equal 180°
