CAN YOU PLEASE HELP ME WITH THIS
schepotkina [342]

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.

A construction worker drops a hammer from a height of 25 m.
Snezhnost [94]

Answer:

Time at which the hammer reaches the ground is 2.3 seconds.

Step-by-step explanation:

We are given the formula as, h(t)=-4.9t^2+v_{o}+h_{o}.

It is known that, when height i.e. h_{o}=25 meter, then velocity v_{o}=0 m/sec.

So, we get the formula as, h(t)=-4.9t^2+25.

Now, when the hammer hits the ground, the height h_{o}=0 meter.

Thus, we have,

h(t)=-4.9t^2+25

⇒ 0=-4.9t^2+25

⇒ 4.9t^2=25

⇒ t^2=5.1

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/
