Answer:
n = 2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan 30 = n / 2 sqrt(3)
2 sqrt(3) tan 30 = n
2 sqrt(3) * sqrt(3)/3 = n
2 = n
Answer:
15 dollers
Step-by-step explanation:
This factors to 64 - 4i^2
64 + 4
68 is the answer
So 3 pounds cost 4$ and we need to figure out how much it is to purchase 1 pound of them.
All you need to do is divide the given cost by the given amount of pounds.
4 / 3 = 1.33333333333
<h3>So 1 pound will cost 1.33$</h3>
Hope this helps!
Let a be the amount of peanuts; and
Let b the amount of walnuts
Equation 1 would be: A + B = 100
249a + 389b = 319 (100)
Equation 2 would be: 249a + 389b = 31900
From equation 1:
a = 100 – b
249 (100 – b) + 389b = 31900
24900 – 249b + 389b = 31900
140b = 7000
b = 50 lbs
then from equation 1:
A + 50 = 100
A = 50 pounds
