Answer:
Step-by-step explanation:
you are given the law of sines, in the question, so i'm guessing you don't get "law of sines" ???
some times I think people might just be lazy and they don't try, but I can understand if you really don't get "law of sines' b/c it is kinda abstract.
Any way here is how you solve this problem and please ask if you don't understand about something I do to solve this. Ask about it if you don't get it. :)
Sin(45) / c = Sin(45) / 3
now algebraically solve for c
3* Sin(45) / Sin(45) = c
if you're thinking the answer is 3 you're right.
indecently , if you didn't notice, this is an isosceles triangle and they do have the same length legs. so you know that x = 3 right away from that, but, it's good to understand Law of Sines as well. :)
Answer:
$0.21
Step-by-step explanation:
Let x be the amount of money earned per hour before raise and y be amount of money earned per hour after raise.
We have been given that before raise he worked 38 hours and earned $220. We can represent this information as:
We are also told that the next week, he received a raise. After raise he worked 30 hours and made $180. We can represent this information as: .
Let us solve for x and y.
Therefore, before raise Mike earned $5.7894 per hour.
Therefore, after raise Mike earned $6 per hour.
Now let us subtract 5.7894 from 6 to find Mike's raise.
Therefore, amount of Mike's raise to the nearest cent is $0.21.
Answer: C
Step-by-step explanation:
1 ml = 0.001 l
1 l = 1000 kl
(14 over 5) · (15 over 5)
= 14·13·12·11·10/5! · 15·14·13·12·11/5!
= 6012006
(n over k) is the Binomial coefficient
The second value of the ratio is guests, which is currently 3. To make this 30, you would multiply it by 10, and do the same to the first value, representing bouncy balls, to get the number of balls necessary for 30 people to maintain the same ratio. 9 * 10 = 90, so 90 balls would be required if the same ratio is to be kept.
