Answer:
∠ BNM = 150°
Step-by-step explanation:
Project MN to meet AB at point P, then
Δ ANP is a right triangle with sum of angles = 180°, thus
x = 180° - (90 + 30)° = 180° - 120° = 60°
∠ BNM = x + 90 = 60 + 90 = 150°
Answer:
25 silk leaves
Step-by-step explanation:
The opportunity cost would be what was normally stopped by doing something else, we have two scenarios:
First stage:
A combination of 60 silk roses and 80 silk leaves
Second stage:
A combination of 70 silk roses and 55 silk leaves
Therefore, comparing the two scenarios, by producing more silk roses, the amount of silk leaves is decreased, by the following amount:
80 silk leaves - 55 silk leaves = 25 silk leaves.
Therefore the opportunity cost is 25 silk leaves

Im pretty sure he earned 495 in interest, because you take 5,500 time .03 (from the three percent) and you get 165- then multiply by three because of the three years (495)
Answer:
a. Concentration of nitrogen in water draining from fertilized lands
b. Quantitative
c. Water draining from fertilized lands
Step-by-step explanation:
a. Here we are evaluating the Concentration in miligrams of Nitrogen per liter of water, that drains from fertilized lands.. So thats what is defined as the variable.
b. When we talk about qualitative variblaes, we refer to variables that we can't define with numbers. For example the colour of a car, that's a qualitative variable. In this problem, can put a number on the nitrogen concetration. When we can measure the variable with numbers we consider it to be a quantitative variable. Therefore this is a quantitative variable
c. The implied population is the population where we want to interfer the analysis. In here we want to know the concentration of water draining from fertilized lands. So we are using random samples from a lake, and we extrapolate that analysis to a bigger universe, that it´s the water draining from fertilized lands
