Answer:
55,637.8 square inches
Step-by-step explanation:
We can find side n using the Law of Sines:
n/sin(N) = p/sin(P)
n = p(sin(N)/sin(P)) = 600·sin(64°)/sin(96°)
n ≈ 542.246913 . . . . inches
The angle O is ...
O = 180° -N -P = 180° -64° -96° = 20°
Then the area is ...
A = 1/2·np·sin(O)
A = (1/2)(542.246913 in)(600 in)·sin(20°) ≈ 55,637.81008 in²
The area of ∆NOP is about 55,637.8 in².
Answer:
Cost = 17.08
Step-by-step explanation:
The cost is 4.88 per pound.
We buy 3.5 pounds
Cost = number of pounds * cost per pound
Cost = 3.5 * 4.88
Cost = 17.08
The mean is the average of the numbers: a calculated "central" value of a set of numbers.
Therefore: If the amount spent on books per month by all her classmates is leveled that amount would be $30
To calculate it: add up all the numbers, then divide by how many numbers there are
Answer:
$104,710.29
Step-by-step explanation:
The amount is given by ...
A = Pe^(rt)
where P is the principal invested at annual rate r for t years. Filling in the numbers, we get ...
A = 30000e^(.05·25) = 30000e^1.25 ≈ 104,710.29
The balance will be about $104,710.29 on the child's 25th birthday.
