The simple reason why it is very important for a given measurement always be reported to the correct number of significant figures is because solved answers usually, frequently and most of the time depend on the number of significant figures in the values used during the calculation
<h3>Significant figures</h3>
There are accurate figures which is used in solving mathematical problems
So therefore, the simple reason why it is very important for a given measurement always be reported to the correct number of significant figures is because solved answers usually, frequently and most of the time depend on the number of significant figures in the values used during the calculation

The grade is the ratio of rise to run, i.e. the slope aka the tangent.


Answer: (a) 6 degrees
For part b, the road is the hypotenuse c of a right triangle whose tangent of the small angle is 1/10. The height h or rise is the side opposite the small angle.


We could just take the sine of the angle we got but let's get it from the tangent exactly.

Dividing by squared cosine





Answer: (b) Rise of 0.199 km
Answer:
By using cross multiplication method, 1/2 is the difference between two fractions 5/6 and 1/3.
Step-by-step explanation:
Answer:
22 units²
Step-by-step explanation:
1/2b*h=area
You can either count the units or use the distance formula.

b = 4 units
h = 11 units
area = (1/2*4)*11 = 22 units²
Answer:
Negative
