I might be biased since I've only ever really done Kumon and Mathnasium as a child and those aren't the best options if you want in depth and higher level difficulty, but I've been doing spirit of math for a while now and I think it's a really good program and that you should consider taking it? They have courses from kindergarten to 11, 11 being equivalent to about a first year or second year university math course (according to their website) and I think they have really good problems (lots of experience just from doing these problems) and teach you really useful skills.
I wish this was sponsered but it isn't lol
tl;dr Spirit of math offers good courses (right know it's online but if there wasn't a pandemic it's in person) and all you need is like a B in all subjects or something like that to get in. Good topics + experience. There are grades but they don't matter :)
From the tangency condition, the smallest radius is 2a.
Opposite angles in parallelogram are =
13x-25 = 9x-1
4x = 24
x = 6 angle a = 13(6)-25 = 53
Angle A and angle D are supplementary (add to 180)
53 + D = 180 D = ..............
Interest = 10000 X .02 x 3
New balance is 10 000 plus interest calculated above....
Anyone else have an answer for this ? I'd like to know if I was wrong and why....or if I was correct.....I kind of 'punted' a bit ...
Thank you so much! I can't believe I didn't think of squaring it!.
Start by squaring the entire thing.
\(a^2 < 77 < (a+1)^2\)
Let's start with the first condition: a^2 < 77. From here, we know that a is equal to 8 or less.
Also, (8 + 1)^2 = 81, which works.
The integer a is 8.
Thank you so much!
1. 30, 540 subtracted from the angles results in 30
2. 6, s=sqrt2*d/2, solve for d
7. regular measure = 120 for hexagon, square =90
CAB=30, (180-30)/2=75, 180-75=105
105+30=135
180-135=$45$
I would like help with all of them if it's possible, thanks!
A Q III
B 5 pi/4
C pi/4
D = 1/sin = - 2/sqrt2 = -2 sqrt 2 /2 = - sqrt 2
This is an aops exam isn't it?
A Q IV
B - pi/4
D = (- sqrt(2)/2) / (sqrt( 2)/2 ) = -1
Which problem do you need help on, or all of them?
B = 15 and C = 90.
similar triangle ratios
5 is to 15 as 6 is to n
5/15 = 6/n
n = 6 * 15/5 = 18 units
You have 26 + 26 + 10 = 62 choices for each of the eight characters positions in your password
862 = 2.183 X 1014
(a,b) = (5 + 7i, 5 - 7i).
The number of ways is 1240.
a + b + c = 8 + 3 + 6 = 17.
Try letting x = a and y = 1/b. Then you should get the result that xyz can be -2, -1, 1 or 2.
x = 1/4.
80*0.2=80/5=16, 82+16=98
For the week 82 + 20% (80) = 82 + .2 (80) = 98 bux
