Answer:
10^3 kg
Step-by-step explanation:
Think about it that you have the total yield 10^8 kg of rice from 10^5 km^2 of land. You now only want How much does 1 km^2 of land produce. Which can be shown as
10^8/10^5=??/1. To get the denominator to equal one you divide the top and bottom of the first problem by 10^5. 10^8/10^5 is 10^3. So it's 10^3 kg
Answer:
heya! ^^
so the question demands us to calculate what is 20% of 60.
that's quite simple. so let's see how we gótta do this question.
hope helpful :D
X=6 is the answer. good luck
Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.
