Answer:

A= 429

B= 50

Explanation:

A+B= 479 (take away)

A-B= 379

A-A+B+B= 479-379 (simplify)

2B= 100

I think you know how to do it now..

B=50

A=50+379 ---> 429

This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!

Which method is valid for proving that two circles are similar?
Masteriza [31]
First I'm going to go through the choices with you and evaluate
each one.  Then after that, I'm going to hand you a secret that
I promise is going to knock your socks off.


a- Calculate the ratio of the diameter to the radius for each circle
and show that they are equal.
-- That won't tell you anything. The ratio of the diameter
to the radius of EVERY circle is 2 .

b- Calculate the ratio of degrees to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The circumference
of EVERY circle subtends a central angle of 360°.

c- Calculate the ratio of the área to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The ratio of the area
to the circumference of EVERY circle is (radius/2). 
They're only equal if the circles are the same size.

d- Calculate the ratio of the diameter to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The ratio of the diameter
to the circumference of EVERY circle is  1/pi.   If the ratio isn't
1/pi, then you're not looking at a circle. 

None of these choices tells you whether the two circles are similar.
What are you going to do ?  How can you tell ? ?

Here's the surprise I promised you.
Beware of flying socks:

All circles are similar to all other circles.

Good night.

What value of “n” makes the equation true?
Doss [256]

Answer:

12 OR 1/12 (Check how you write your equations! Just look below for the one that it actually is lol)

Step-by-step explanation:

6 = (1/2)n

6/(1/2) = n

12 = n

OR

6 = 1/(2n)

6(2n) = 1

12n = 1

n = 1/12

Suppose you have a tablet with a capacity of 35 gigabytes. for a plain text​ book, one byte typically corresponds to one charact
steposvetlana [31]
The first thing we must keep in mind is the following unit conversion:
 1 gigabytes = 1 * 10 ^ 9 bytes

 We have then that for 35 gigabytes:
 35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes


 Part A:
 
For this case we make the following rule of three:
 2000 bytes --------------> 1 page
 35*10^9 bytes ----------> x
 From here, we clear x:
 x = (35 * 10 ^ 9) / (2000)

x = 17500000 pages

 Part B:
 
Then, the number of 500-page books is:
 n = (17500000) / (500)

n = 35000
