Let x=0.166666...-----------(1equation)
Multiplying by 10 in both sides
10x=1.66666...-------------(2equation)
Multiplying by 10 in both sides
100x=16.6666...----------(3equation)
Subtracting 2equation from 3equation
100x-10x=16.666..-1.666..
90x=15
x=15/90
0.16666....=15/90
[Note that you don't have to evaluate k to solve the problem]
That means that
So, you want such that
70% of the students pack there lunches. 14/20 = 7/10 = 0.7
Answer:
60°
Step-by-step explanation:
90+30=120°
180-120=60°
Answer:
x = 79
Step-by-step explanation:
This is an isosecles triangle so the bottom angles have equal measure
and since the sum of interior angles in a triangle is equal to 180
2x + 32 = 180 subtract 32 from both sides
2x = 158 divide both sides by 2
x = 79
