3 divide by what number equals 5

1 answer:

4 0

First write the equation
3/n = 5

Multiply both sides by n
3/n * n = 5 * n

Simplify
3 = 5 * n

Divide both sides by 5
3/5 = 5 * n/5

Simplify
3/5 = n

Divide
0.6 = n

So 3/0.6 = 5

Answer:

answer of 11

Step-by-step explanation:

given A=30°

R.H.S=2sinA cosA

=2 * sin30° * cos30°

$2 \times \frac{1}{2} \times \frac{ \sqrt{3} }{2}$

$= \frac{ \sqrt{3} }{2}$

=sin60°

sin 2*30°

=sin2A

L.H.S=R.H.S

A right circular cylinder is changing shape. The radius is decreasing at the rate of 2 inches/sec while it's height is increasin

Savatey [412]

Answer:

Step-by-step explanation:

Volume of a cylinder is expressed as;

$V = \pi r^2 h$

$\frac{dV}{dt} = \frac{dV}{dr} \frac{dr}{dt} +\frac{dV}{dh} \frac{dh}{dt}$

dV/dr = 2πrh

dV/dr = 2π(4)(6)

dV/dr = 48(3.14)

dV/dr = 150.72in³/m

dV/dh = πr²

dV/dh = 3.14(4)²

dV/dh = 50.24

Given

dh/dt = 5in/s

dr/dt = 2in/s

Substitute into the dV/dt

dV/dt = 150.72(2)+50.24(5)

dV/dt = 301.44 + 251.2

dV/dt= 552.640in³/s

The volume is changing at the rate of 552.640in³/s
