You need to do the following equation:
(5/12)*(3/10)
5*3=15
12*10=120
15/120=5/40 of the adults who visited were men.
Answer:
5-24.97
7-92.31
8- -14.16
Step-by-step explanation:
Yes because K is a variable not a number
Answer:
∠ ADC = 100° , ∠ DCB = 39°
Step-by-step explanation:
(3y + 7) and ( 3y - 13) are angles on a straight line and sum to 180° , so
3y + 7 + 3y - 13 = 180
6y - 6 = 180 ( add 6 to both sides )
6y = 186 ( divide both sides by 6 )
y = 31
Then
∠ ADC = 3y + 7 = 3(31) + 7 = 93 + 7 = 100°
and
∠ BDC = 3y - 13 = 3(31) - 13 = 93 - 13 = 80°
∠ BDC = 180° - (61 + 80)° ← angle sum in Δ BCD = 180°
= 180° - 141°
= 39°
