Answer:
d. 32.9
Step-by-step explanation:
To find c, we'll use the Law of Sines that says:
And we'll isolate a to get:
We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have
So, let's round it to 32.9 to match the answer number D.
The formula for interest compounded annually is A=P(1+(r/n)^nt.
In this context: A=50,000 r=0.036 n=1, since it's compounded annually (Once per year) and t=10.
Now plug in and solve for P.
50,000=P(1+(0.036/1)^(1 * 10)
50,000= 1.42 P (I just distributed).
Divide both sides by 1.42 to get a final answer of $35,105.28.
5n+5p is the right answer.
Answer:
$3.08 for 7 stamps
Step-by-step explanation:
The unit rate (price per stamp) is:
$2.20
-------------- = $0.44/stamp
5 stamps
Then 7 stamps would cost:
$0.44
------------ * 7 stamps = $3.08 for 7 stamps
1 stamp
