Answer:
Step-by-step explanation:
They are testing whether you remember the basic 30,60,90 degree triangle side relationship. The ratio of sides for this triangle are 1 opposite the 30 degree angle, square root of three opposite the 60 degree angle and a hypotenuse of 2 opposite the 90 degree angle.
x/2=2/1
x=4/1=4
bottom answer choice
x/4=3^(1/2)/1
x=4(3^(1/2))
third answer choice
6 1/3=19/3
8.25=8 1/4=33/4
in multiplying fraction, all you have to do is
multiply the numerators 19x33=627
same with the denominators 3x4=12
627/12 reduce if possible
209/4
Answer:
7 / 10 14 / 20 21 / 30
Step-by-step explanation:
7 out of 10 is its simplest form the equivalent ratio of 7 * 210 * 2 equals 14 / 27 / 10 * 3 * 3 equals 21/30 letter answer
Games: $471; System: $157
s = cost of the system, and g = cost of the games
It is given that s+g = 628
and g=3*s
s+3*s = 628
4s = 628
s = 157
s+g = 628
157+g= 628
g= 628-157
g= 471
