see attached image. sorry that’s it’s all jumbled up weird, i could only figure out how to put them all together using photoshop. hope these help you out :))
The answer is B, 3210. the square root of 3210 is 56.6569 which is not a perfect square.
X = 160 because you can set this problem up like an equation by having all the angles added together to equal 720
d $=d*100 cent
Let the unit cost of soda be p cents. So, unit cost of hot dog=2p cents
Total cost=cost of hot dog+cost of soda
or, 100d=h*2p+s*p=p(2h+s)
Or, p=100d(s+2h)p=100d(s+2h)
Remember:
x/y times z/t=(xz)/(yt) and
x/y+z/y=(x+z)/y
conver the bottom number to the same number as the 21/100 or convert 10 to 100
obviously multiply by 10
but msut multiply by 1 to keep same value
remember that 10/10=1 so
multiply 3/10 by 10/10
3/10 times 10/10=30/100
so add
30/100+21/100=(30+21)/100=51/100
