Answer:
Step-by-step explanation:
so the question is asking about the time from 1500 feet to 1100 feet. How long did they fall, w/o a parachute. aka "freefall" so, at 1500 feet the jumper is really at time zero. so, plug in to the formula
1100 = -16
+1500
( x represents seconds so i'll change it to t so we know it's time )
1100 = -16
+ 1500
now we can solve for t , to see how long the jumper falls
-400 = - 16 ( subtracting 1500 from both sides of equation )
25 = ( dividing both sides by -16 )
oh.. look at how nice that turns out.. :)
= t ( take the square root on both sides )
5 = t
the jumper fell for 5 seconds to get to 1100 feet
Answer:
28
Step-by-step explanation:
32 - 9 = 23,
24 + 4 = 28
He started at the wrong end of the number.
He should have started with the 3-8 and borrowed ending up with 85
To answer this question we have to go through each answer, and use this equation:
(a = area, w = width, l = length, h = height)
a=2(wl+hl+hw)
to solve, and see if it's correct.
A) a=2(9·4+3·4+3·9) = 150
<span>Correct!
</span>B) a=2(3·7+4·7+4·3) = 122
Incorrect.
C) a=2(5·8+5·8+5·5) = 210
Incorrect.
D) a=2(7·5+6·5+6·7) = 214
Correct!
The correct answers are A, and D.
