As it says in the answer, you usually add / subtract the exponents when needed.
Answer:
57.3°
Step-by-step explanation:
A 25 feet ladder leans against a building.
The ladder's base is 13.5 feet from the building.
The ladder, the wall of the building and the ground form a right-angled triangle of:
Hypotenuse = 25 feet
Base = 13.5 feet
We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)
Let's say the angle = X°
According to a trigonometric equation;
cos X° = adjacent side ÷ hypotenuse = 
= 0.54
= 57.5=3° (Answer rounded up to nearest one decimal place).
∴ The angle of elevation = 57.3°
well, let's assume you haven't been dead for 3 years then, 30,400 a year, expressed as a unit rate per hour?
assuming a year has 365 days.
a day has 24 hours, therefore a year will have 365*24 hours.
so 30400 per year, will be 30400/(365*24) per hour, namely about 3.47031963, which we can round up to about 3 deaths per hour.
First let's find the result of the sum:
30 + 40 + 70 = 140
Now let's review the operations of each one:
Jillian added 30and40and then 70:
30 + 40 = 70
70 + 70 = 140
Samuel added 30 and 70 and then 40
30 + 70 = 100
100 + 40 = 140
answer
both are correct.
Conclusion: the order of the factors does not alter the product.
