Y=68+4x
100=68+4x
-68=-68
32=4x
Divide both sides by 4 
x=it will take 8 min. for the water to reach 100 degrees
y=total degrees 
x=#  of minutes

If a wind turbine makes 76 full revolutions every 1 minute what is it’s angular speed?
Maslowich

Answer: 7.958 \frac{rad}{s}

Step-by-step explanation:

We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed \omega of the object in revolutions per minute (rpm) is:

\omega=76 rpm=76 \frac{rev}{min} (1)

However, we have to convert this to \frac{rad}{s}, since this is the unit used in the International Systme of Units for angular speed.

So, we can do this knowing that:

\omega=\frac{2 \pi}{T}  (2)

Where:

2 \pi=360\° is the value of one revolution

T=1 min=60 s is the period of rotation

With this information in mind, let's make the conversion:

\omega=76 \frac{rev}{min}. \frac{1 min}{60 s}. \frac{2 \pi}{1 rev} (3)

\omega=7.958 \frac{rad}{s} (4) This is the wind turbine angular speed

Geometry math question no Guessing and Please show work thank you
Lelu [443]

DE + EF = 4x+2

DE = x+7

EF = 7

Substitute these in

x + 7 + 7 = 4x + 2

x + 14 = 4x + 2

subtract x from both sides

14 = 3x + 2

subtract 2 from both sides

3x = 12

divide both sides by 3

x = 4

substitute this in to find the length of DE

DE = x + 7

(4) + 7 = 11

the answer is 11
