Step-by-step explanation:
ans.
Total ratio of votes=6+5
=11
1 ratio of votes=6644÷11
=604
Ratio of no votes=5
Number of no votes=Ratio of no votes×1 ratio of no votes
=604×5

To get the reciprocal, simply flip the numerator and denominator. The reciprocal of 3/10 is 10/3.
Step-by-step explanation:
Total money paid=$110+$5.5=115.5
Cost of each shirt=$8
Therefore,
No. of T shirt req.=115.5/8=14.4
So they req. 15 T-Shirts
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
