Vlada [557]

At the time 4 PM will it be after they each have worked 4 shifts. Option E is correct.

<h3>What exactly is simplification?</h3>

Simplifying means making something easier to do or comprehend, as well as making something less difficult.

Mashud and Iqbal are security guards at a top-secret federal vault. They each work 8-hour shifts, If Mashud begins his shift at 8 PM,

The time will it be after they each have worked 4 shifts;

8 PM + 8 hour =4 AM

4 AM + 8 hour = 12 PM

12 PM+ 8 hour =8 PM

8 PM + 8 hour = 4 PM

Hence,  option E  is correct.

They will each have worked four shifts by the time it is 8 PM.

A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 2x. Find the height of t
weqwewe [10]
V(cylinder)=πR²H
Radius of the cylinder R=x, height of the cylinder H=y.
We can write for the cylinder
V(cylinder)=πx²y

V(cone) =(1/3)πr²h
Radius of the cone r=2x.
We can write for the cone
V(cone)= (1/3)π(2x)²h=(1/3)π *4*x²h

V(cylinder) =V(cone)
πx²y=(1/3)π *4*x²h
y=(4/3)*h
h=(3/4)*y
