Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units
Sorry this took me so long to answer!
Answer:
Justice lived in Germany for 15 months and he lived in Holland for 9 months.
Step-by-step explanation:
1. You must make a system of equations:

Where
is the number on months he lived in Germany and
is the number on months he lived in Holland.
2. You can solve this system of equations by using the Elimination Method. If you multiply the first equation by -120, you can cancel the variable
when you add both equations, and then you can calculate
. When you obtain the value of
, you can substitute it into one of the original equations and solve for
. Then:



5+5 equals 55 and 2+2 equals fish :v

Answer:
42 tickets
Step-by-step explanation:
First winning = 90 tickets
Bonus won = 5 times the number of tickets of the original second prize
Total tickets won = 300
That is ;
First winning + bonus = 300 tickets
Let :
Number Tickets won by original second price = x
Bonus = 5x
Then;
90 + 5x = 300
5x = 300 - 90
5x = 210
x = 210 / 5
x = 42
