Answer:
Step-by-step explanation:
In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,
Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.
In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio (
) to solve for the unknown. Substitute in the given values,
Manipulate the equation such that it is solved for the parameter(x),
Solve,
Answer:
N$ 612.5
Step by step explaination:
Given,
Principal or'P'=N$2500
Time or'n'=3 years & 6 months or 3.5 years
Rate of profit or 'r'=7% or 7/100
Profit or 'I'=?
_____________________________________
We know,
I=P*n*r
I=2500*3.5*7/100
I=612.5
So,simple interest is N$ 612.5.
I think the order is step 3, step 1, and then step 2
Your answer for air is correct. Glass has a higher refractive index compared to water.
So the answers should go in this order: Water, Glass, Air
Explanation:
Light moves slower in glass, so glass has a higher refractive index than water. This means that light is refracted at a greater angle
We should first convert 23 1/2 million dollars to a mixed number:
Then we need to divide this by 4, since 4 people won an equal amount of the prize:
And to solve this, we must multiply both the numerator and the denominator by 
. This will then cancel out the 4 in the denominator:
This is the amount each individual person won; we must convert this to a mixed number since the question asked us to:
So now we know that each person won 
million dollars.
