Answer:
first one
Step-by-step explanation:
The <u>correct answer</u> is:
The scale drawing is larger.
Explanation:
A scale for a scale drawing is written as a ratio in the form
(scale size):(actual size).
For example, on a map you may have a scale that says 1 in: 2 mi. This means that 1 inch on the scale is equal to 2 miles on the map.
The scale for this problem is 10 cm: 1 mm. This means that 10 cm on the scale drawing represents 1 mm on the actual object.
10 cm is larger than 1 mm, so the scale drawing is larger.
180 - 34 - (180 - 115). 180°, and the sum of all interior angles in a triangle is 180°.
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
