Ayanna bought three dozen donuts from Dunkin Donuts. She wants to share these between herself and three friends. How many donuts
Thepotemich [5.8K]

Answer:

9

Step-by-step explanation:

Ok... So there are 12 donuts in a dozen. And if she bought 3 dozen, she will have 36 donuts. If she plans to share them with her 3 friends, there will be 4 people total sharing the donuts. Then all you have to do is divide the 36 donuts among the 4 friends. 36/4=9. So they will all get 9 donuts.

3(12)/4=x

36/4=x

9=x

<u>x=9</u>

The pressure, P (in lbs/ft2 ), in a pipe varies over time. Five times an hour, the pressure oscillates from a low of 90 to a hig
Lunna [17]

P=160-70*cos(2π*(1/12)*t)

• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

So, combining everything we get

P=160-70*cos(2π*(1/12)*t)

Given the equation,D=m/v if D=6/7 and =m+3 then m=.
mamaluj [8]

Answer:

m=18

Step-by-step explanation:

The equation given is D=\frac{m}{v}

and also we have that D=\frac{6}{7}, thus:

\frac{6}{7}=\frac{m}{v}

------------

I think the question is missing which variable is defined as =m+3, so I will solve for v=m+3 since is the only other variable in the equation.

substituting v=m+3  into \frac{6}{7}=\frac{m}{v}:

\frac{6}{7}=\frac{m}{m+3}

and we solve for m:

(m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m

m is equal to 18.
