2 1/2 yds = 2.5 x 36 = 90 inches...what she started with

2 ft 8 in = 2(12) + 8 = 32 inches...what she had left

90 - x = 32
90 - 32 = x
x = 58 inches....so she used 58 inches

What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?

Kay [80]

Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = $d(\pi r^h ) / dt$

= $\pi h\frac{d(r^2)}{dt}$ = $-\pi h *2r *dr/dt$

hence ; dv / dt = -2400 π

7 x 5e = 105 <br><br><br>plz help

Anon25 [30]

e=3.

So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
