Answer:
what question is this
please explain more
Step-by-step explanation:
To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:
A/P = 1 + rt.
Next, isolate rt by subtracting 1 from both sides:
A/P - 1 = rt
Finally, divide both sides by t:
A/P - 1
----------- = r
t
This could be written in other formats, such as:
A - P
-------- = r
Pt
Answer:
Find below the calculations of the two areas, each with two methods. The results are:


Explanation:
<u>A) Method 1</u>
When you are not given the height, but you are given two sides and the included angle between the two sides, you can use this formula:

Where,
is the measure of the included angle.
1. <u>Upper triangle:</u>

2. <u>Lower triangle:</u>

<u></u>
<u>B) Method 2</u>
You can find the height of the triangle using trigonometric properties, and then use the very well known formula:

Use it for both triangles.
3. <u>Upper triangle:</u>
The trigonometric ratio that you can use is:

Notice the height is the opposite leg to the angle of 60º, and the side that measures 100 units is the hypotenuse of that right triangle. Then:


3. <u>Lower triangle:</u>

Answer: 4611/1000
Move the decimal place until it is a whole number and if you moved it 3 places the denominator will have that much zeros
Answer: 
<u>Multiply both sides by 5/3</u>
