Set h to 640 and solve for t:
640 = -490t^2 + 1120t
Subtract 640 from both sides:
-490t^2 + 1120t - 640 = 0
The formula to solve a quadratic equation is:
x = -b -/+ sqrtroot (b^2-4ac)/(2a) where a = -490, b = 1120 and c = -640
Solve:
x = -1120 -/+ sqrtroot (1120^2-4(-490)(-640) )/ 2(-490)
x = 8/7 = 1.1428 = 1.14

A producer is said to have an absolute advantage over another producer when he required less amount of input to produce the same good compared to the other producer.
While a producer is said to have a comparative advantage over another producer when he produces his goods at a lesser opportunity cost compared to the other produer.
Here, time is one of the inputs used in production and Maria produces a scarf at a lesser time compared to Sofia. Thus, Maria has an absolute advantage over Maria in the production of scarves.
Therefore, the true statement is "<span>Maria has an absolute advantage over Sofia".</span>
Answer:
(-b-81)/6=a
Step-by-step explanation:
3b−2a-17 = 4a+4b+64
3b-4b-17-64=4a+2a
-b-81=6a
(-b-81)/6=a
x
1 x 5 = 5
16 x 4 = 64
is the answer
In simplest form the answer would be
because it cant be divided any farther.
