The other angle has to be 50 degrees. To figure this out, you have to know complementary means. It means that the angles add up to 90 degrees. So, then you have to do 90 minus 40 to find the missing angle number. The difference is 50.
Answer:
(mn+n²)/(m+n)
Step-by-step explanation:
probability of blue marble= n/(n+m)
probability of red marble= m/(n+m)
probability that process stops = Probability of both blue + probability of both red= n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)
= (n²+m²)/(n+m)²
P(1st marbel is blue)= P(blue and red) + P(blue and blue)
= mn/(n+m) + n²/(n+m)
= (mn+n²)/(m+n)
P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)
= (mn+n²)/(m+n)
Answer:
y = 97°
Explanation:
Opposite angles in a quadrilateral inscribed in a circle sum ups to 180°
So following the rule:
A + C = 180°
y + 83° = 180°
y = 180° - 83°
y = 97°

Answer: each bottle costs $0.91
Step-by-step explanation: the total amount (before tax) is $5.49, we already know that one bag of apple was purchased for $1.85 so we can subtract that from the total. $5.49-$1.85=$3.64 Four bottle of juice were purchased so we can divide $3.64 by 4 which equals $0.92
