Answer:
Step-by-step explanation:
a. 29/8 + 2(19/4) + 3(27/8) = 29/8 + 38/4 + 81/8 = 29/8 + 76/8 + 81/8 = 186/8 in.
b. 186/8 times 2 = 372/8 in
c. the shortest plane would be 27/8 and the largest would be 19/4 or 38/8.
If you subtract the two, you get 11/8. The difference is 11/8 in.
<span>The 2 factors of 24 that add up to 11 are 3 and 8. We know that 3 and 8 are also both factors of 24 because 3x8=24.</span>
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as,
.
It is known that, when height i.e.
meter, then velocity
m/sec.
So, we get the formula as,
.
Now, when the hammer hits the ground, the height
meter.
Thus, we have,

⇒ 
⇒ 
⇒ 
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
Answer:
k= 5b-3/
4
Step-by-step explanation:
3−3k+7k=5b
(Combine −3k and 7k to get 4k.)
3+4k=5b
(Subtract 3 from both sides)
4k=5b−3
(Divide both sides by 4.)
k= 5b-3/
