Answer: 25 bags of chips and 25 soda
Step-by-step explanation:
The amount I have with me is $100.
Since bags of chips cost $3 each and Soda costs $1 each. Both will cost total of $4 each.
In order to know the amount I can buy with $100 that is with me, I will have to divide $100 by $4 which gives $25.
This shows I can get 25 bags of soda @$25 at the rate of $1 each and have a balance of $75 which is enough to buy 25bags of chips @$3 each.
Since b = c, the angles B and C also equal
so you get
180 - 45 = 135
135/2 = =67.5 for each angle
now we know 2 sides and all 3 angles, use the law of sines to find a
b/sin B = a/sin A
4/(sin 67.5) = a/(sin 45)
a = 4(sin 45)/(sin 67.5)
a^2 = (4(sin 45)/(sin 67.5))^2
a^2 = 9.37
Answer is C
Answer: The boys ate half a pie more than the girls did (5/10 more).
Step-by-step explanation:
2/5 = 4/10
The difference between 9/10 and 4/10 is 5/10, or one half, so that's your answer.
