Step-by-step explanation:

a=12,l=10,h=?

Using pythagorus theorem;

   h=10cm, p=? and b=12/2=6cm

now,

    p=\sqrt{x}h^2+b^2

       =\sqrt{10^2+6^2

A manufacturing machine has two processes. One of them is repeated 4 times and the second only once. The entire cycle
Allushta [10]

Answer:

The inequality representing the time taken by the entire cycle is:

4x+y\leq 3

Step-by-step explanation:

The time taken to complete one cycle of a manufacturing machine is no longer than 3 minutes.  

It is provided that the manufacturing machine has two processes.

One of them is repeated 4 times and the second only once.

Assume that the variable <em>x</em> represents the time taken to complete the first process once.

Then the  time taken to complete the first process 4 times would be, 4<em>x</em>.

Also assume that the variable <em>y</em> represents the time taken to complete the second process.

Then the inequality representing the time taken by the entire cycle is:

4x+y\leq 3

Consider the graph below representing the above equation.

DeShawn left the hospital and drove toward the ferry office at an average speed of 30 mph. Shaun left sometime later driving in
kvv77 [185]

Answer:

The number of hours DeShawn drove before Shaun caught up = 5 hours

Step-by-step explanation:

Average speed of DeShawn = 30 mph

Average speed of Shawn = 50 mph

After driving for three hours Shaun caught up with DeShawn.

Distance traveled by Shaun in 3 hours,

               Distance = Time x Average speed = 50 x 3 = 150 miles.

So DeShawn also travels 150 miles, we need to find time DeShawn taken to travel this 150 miles,

                Distance = Time x Average speed

                  150 = Time x 30

                   Time = 5 hours.

The number of hours DeShawn drove before Shaun caught up = 5 hours
