YEE complementary counting!
yes
so basically, what that is guest is you count the solutions you DONT want, then subtract. This is because it is sometimes faster this way.
Welp the image has been blocked so idk
Honestly, this is just a bash.
test test test.
Did you get it?
If so, nice!
So we have 12 liters in the end.
First, we can set acid percentage to 10%
a=.1
And we also have 12-a as the full solution at 100%
Soo..
.1a+12-x=.3(12)
solve the rest
:D
I got the same for 1
1) the angles in this ratio 3:7 add up to 90. So 90/(10)=9, 9*3=27, 9*7=63. 63 is your answer, and checking, we have 63+27=90
If you can't tell even at this point...
i really don't know what to say
try using a bit more brainpower.
Maybe try simplifying your equation you have?
Wait why is that?
OooOOh because we're on a clock? okie
How did you come to that?
is there like a rule?
But isn't it asking for the shaded?
Im really bad at trig
don trust me but
We have Pythagorean theorem, 36+x=100, x=64, AC=8.
Now, cos A would then be i THINK AC/BC, which is 8/10. Or, exactly 0.800000000.
I got the same thing!
\(\frac{1}{\sqrt{10}}\)
Nice work! I guess you have that many upvotes for a reason
Doesn't look like it, but I would just like to check.
hint:
Either:
average the solutions for x
find the vertex
Well
your name certainly is correct then
62) Just solve the system...?
Expand:
18+3x=8x-3x
Move all x to right:
18=8x-3x-3x
Combine:
18=2x
Divide by 2:
9=x
why was the previous picture "blocked by moderator!"?
Triangle with legs 12 & 16 has a hypotenuse of 144+256=400, sqrt400=20.
Now, realize that these are similar triangles (as an exercise, figure out why!)
So, we have 20:16=x:20
Solve that.
You can factor and use the circle formula, which is:
\((x – h)^2 + (y – k)^2 = r^2\)
the center (h, k) and the radius r
Hmmm
nevermind
I got it right
you can still solve if you want though :p
Hi, Melody! Please correct your diagram; CQ = 7 and QD = 3
Thanks!
AR:AC = 6 / 13
I used 10 cm square and the result is the same as Melody's
Point B travels 3/4pi inches more than point A.
here is the picture:
x^2 + 4x + y^2 + 6y = 51 complete the square for x and y
(x+2)^2 + (y+3)^2 = 51 + 4 + 9 this is a circle with center -2 -3 and radius 8
x^2 + 4 + y^2 + 6y = 3
(x+2)^2 + (y+3)^2 = 3 + 4 + 9 this is a circle with center -2 -3 and radius 4 (diameter 8)
