Answer:
99.4 feet.
Step-by-step explanation:
You'd add 52.7 and 46.7, including 52.7 because she was already 52.7 feet under before she went even deeper.
42 = 2(W+L)
21= (W+L)
L= 3+5W)
21= W +(3+5W)
21= 3+6W
21-3=6W
18=6W
W=18/6
=3
Answer:
w = PERIMETER/2 - LENGTH
<u>w = 42/2 - (3+5w)</u>
PS. I THINK THIS IS RIGHT. NOT TOO SURE, BUT MOST LIKELY.
Answer:
the first one
Step-by-step explanation:
because x has an coefficient
<em>1452 feet</em>
- Step-by-step explanation:
<em>1 hour = 60min×60sec = 3600 sec</em>
<em>1 miles = 5280 feet</em>
<em>22 miles = 22×5280ft = 116160 ft</em>
<em />
<em>3600sec ................. 116160 ft</em>
<em>45sec ................................ x ft</em>
<em>x = 45×116160/3600</em>
<em>= 5227200/3600</em>
<em>= 1452 feet</em>
