Create a System of Equations:

25x + 5(x+16) = 590

solve yourself

9*7=63

Since this is an isoceles, angle A and B = 75

Now we do sin and cos stuff here

6 sin 75 =~ 5.8

6 cos 75 = 3.1

and i think the area would be (3.1*5.8)/2 which is 8.99 ~ 9

not exactly 

but eh

Or use point slope

we know slope is 3

so

 \(y-3=3(x-4)\\ y-3=3x-12\\ y=3x-9 \)

so -9

Slope =   -9/-3 = 3

   y = 3x + b    sub in one of  the given points to calc b

   3 = 3(4) + b     b = -9

Angle  A and  B are equal  =  75 degrees

6 sin 75 = height =  ~ 5.8          6 cos 75 = 1/2 of the base       base = 3.1

area = 1/2 base * height =  1/2   3.1  *  5.8 =  9 units²

A petagram is 10¹⁵  grams

2 x 10^-16  gm / 10¹⁵  gm/ petagram = 2 x 10^-31  petagram

thanks for the explanation. 

Right!  ...........

Now that you have an answer, you delete the fucking question, leaving Geno’s answer post looking like a moronic orphan.

You should be banned!!

Yeah I hope that nobody gets covid and stays happy 

we have the 6 edges(not including corners) that have exactly two faces painted which means there is (5-2)6=3*6=18 sides that have exactly two faces painted so we have \(\boxed{18\text{ sides with exactly two faces painted}}\)

We have the equation 25x+5(16+x)=590 We distribute to get 25x+(5)(16)+(5)(x)=590 then we combine like terms to get (25x+5x)+(80)=590 then 30x+80=590 Next we subtract 80 from both sides 30x+80−80=590−80 then 30x=510 so we have that x=17 so Gisele has \(\boxed{17\text{ quarters}}\)

Hi Guest!

Let x be the number of quarters Gisele has. Thus Gisele must have x+16 nickels. 

To calculate cents, we can write 25x + 5(x+16) = 590

Simplifying, 25x + 5x + 80 = 590 or 30x = 510

Solving for x, we get x = 17

Gisele has 17 quarters.

By the way the question is asked, I assume that none of the sums land on an axis.

The easist way to do this is to assign values to each of the complex numbers, such as:

     z₁  =  1 + 5i     z₂  =  -4 - i     z₃  =  -3 + 4i     z₄  =  5 - 3i

and then find each of the sums, locating the quadrant that contains each of the sums.

I have figured out the answer which is, 3,3,4,3,2,4

2²⁰⁰¹ · 5¹⁹⁵⁰ / 4²⁷  

Since  4²⁷  =  (2²)²⁷  =  2⁵⁴   --->   2²⁰⁰¹ · 5¹⁹⁵⁰ / 2⁵⁴  

                                              --->   ( 2²⁰⁰¹ / 2⁵⁴ ) · 5¹⁹⁵⁰ 

                                              --->   2¹⁹⁴⁷ · 5¹⁹⁵⁰ 

                                              --->   2¹⁹⁴⁷ · 5¹⁹⁴⁷ · 5³

                                              --->   10¹⁹⁴⁷ · 5³ 

                                              --->   5³ · 10¹⁹⁴⁷ 

                                              --->   125 · 10¹⁹⁴⁷ 

                                              --->   1.25 · 10² · 10¹⁹⁴⁷

                                             --->   1.25 · 10¹⁹⁴⁹  

I'll let you take it from here ...  

Thank you for the help, I found the hypotenuse was 5 and found sin L to be 2/5

Is it a tinypic photo? TinyPic has recently shut down, and deleted the pictures of all the users who have had a free account...(sigh, competition between google photos...)...I'm no internet expert...but I think they might be gone forever? Just include the link of your previous question, and I may be able to reanswer it...

:)

Hint: Use AM-GM inequality. which states that \(\frac{x+y}{2}\geq\sqrt{xy}\). (You can prove this with the trivial inequality. )

Please don't post AoPS problems. Is this from Algebra B?
