Answer:
11/40 + 1/4 + 1/20
Step-by-step explanation:
Draw a Venn diagram: (as shown)
Consumer Ed. : 22-4=18
French : 20-4=16
Neither : 80-18-16-4=42
Using probability notation where P(A) means probability of event A occurring.
P(Consumer Ed.) = 22/80
P(French) = 20/80
P(Both) = 4/80
<em>'or ' </em>in the question means you add.
=> 22/80 + 20/80 + 4/80
=> 11/40 + 1/4 + 1/20
4/6=2/3 (divide both numerator and denominator by 2 (gcd)).
Hope this helps.
True,
Good luck! I hope I helped!
Respuesta:
1/2 litros
Explicación paso a paso:
Dos botellas de 3/4 litros:
Litros totales = 2 * 3/4 = 6/4 litros
Número de personas entre las que se dividirá = 3
Fracción que cada uno obtendrá:
Litros totales / número de personas
= (6/4) ÷ (3)
= 6/4 * 1/3
= 6/12
= 1/2 litros
First, we have to find the length of each side of triangle. Equilateral triangle means 3 sides r in same length, so each side will be 21 ÷ 3 = 7
Now we need to calculate the height of the triangle. We can do this by Pythagoras theorem
Let the height be h
(7/2)^2 + x^2 = 7^2
The area should be 6.0621778265
Or u can say 6.06 corrected to 3 sig fig
