Answer:
i think its the 3rd one im sorry if im wrong
Step-by-step explanation:
Julie cannot be right. That's because if you add three odd numbers together, <em>you always get an odd number. </em>The number 50 is an Even number.
Let's try adding 3 odd numbers together a couple of times...3 + 3 + 3 = 9 5 + 1 + 5 = 11 7 + 3 + 5 = 15
We tried 3 examples, we could not get any even number. So,
Julie's claim is wrong.
Question 50.
a. Description
You walk 0.5 miles during 10 minutes, stop and wait for the bus during 4 minutes, then ride the bus for 2 miles during 4 minutes.
b. slopes
the slope of each line represents the average speed of every track.
1) first track
slope = 0.5 miles / 10 minutes = 0.05 miles / minutes.
Given that the slope is constant, you walked at a constant speed of 0.05 miles/minute.
2) second track
slope = 0 => you didn,t move (you were waiting the bus)
3) third track
slope = (2.5 - 0.5) miles / (18 min - 14 min) = 2 miles / 4 min = 0.5 miles / min
means the speed of the bus was constant and equal to 0.5 miles / min.
Ellie: 20*15=300
Heather: 18*18= 324
Heather's floor model is greater by 24 feet
Y = 8/cos60 = 16
x = sqr(16^2 + 8^2) = 8sqr(3) = 13.86 approx
