Answer:
87.5%
Step-by-step explanation:
7 are shaded
8 total boxes are there
7/8= .875
.875*100=87.5%
Answer:
4.0
Step-by-step explanation:
Using trig identity Tangent, tangent is equal to opposite / adjacent side. Therefore tan30 = x/7, because x is the side opposite to 30 degrees and it is adjacent to 7, (note: adjacent side is never the hypotenuse)
To save time, tan 30 = sqrt(3)/3,
sqrt(3)/3 = x/7
x = 7*sqrt(3)/3 ~ 4.041
So the factors are
79=2*5*7
100=2*2*5*5
2*5 is common to both so that is the greatest common factor (10)
10 is the answer
