Answer:
14.60
Step-by-step explanation:
Note that there are 100 centimeters in 1 meter. The plant is 13 meters tall, and grows 8 centimeter every month. It is asking you for 20 months worth (x = 20) of growth.
First, solve for the amount of centimeters total in 20 months:
8 centimeter per month x 20 months = 160 centimeters per 20 months.
Remember, there are 100 centimeters in every meter. Therefore:
160 centimeter/ 100 centimeters per meter = 1.60 meters.
Add the growth to the original height:
13.00 + 1.60 = 14.60
14.60 meters is your answer.

the answer is G) Change 30 to 3,000
D might be the answer I am pretty sure it is D if not then sorry

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.
Angle x isn't the same as the 40° angle so it must be its supplement.
Answer: C 140°

r=1.2, h=2.9, V = (1/3) πr²h
Nothing hard here, we just plug in the numbers,
V = (1/3) π (1.2)² (2.9) ≈ 4.37310
Answer: B. 4.4 cubic inches
4.
Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is
Answer: B similar not congruent
5.
The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°
Answer: A 70°
