Problem 16)
We use ASA (angle side angle) to show the two triangles are congruent. Why ASA instead of AAS? Because the single pair of sides are between the two angles.
--------------------------------------------
Problem 18)
Similar to problem 16, we'll have two pairs of congruent angles, and a pair of congruent sides. However, the sides are NOT between the two angles. So that means we use AAS in this case.
Answer:
20%
Step-by-step explanation:
The answer is option D) The point where the fence post enters the ground.
Step-by-step explanation:
Given,
The fence above the ground= 6 feet
The fence below the ground= 4 feet
Total height of the fence= (6 feet +4 feet)= 10 feet
option A) The middle of the fence is somewhere between 0 feet and 10 feet. It may be any value (example: 2 feet or 5 feet or anything between 0 to 10).
option B) The top of the fence is the topmost point of the fence which is 6 feet from inside the ground and 10 feet from above the ground.
option C) The bottom of the fence is 4 feet from the ground and 10 feet from the top of the fence.
option D) The point where the fence post enters the ground represents the exact point along the ground. The point is a (small dot mark) which is 0 feet.
Answer:
a statistical question is one that we can answer using data
example: How much do 5 gorillas weigh at the zoo called wilderness?
Answer:
a) rounded to the ones place and 2 significant figures.
b) rounded to tenths place and 1 significant figure.
Step-by-step explanation:
Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.
A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.
B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
