Alborosie

Answer: Town 1

Step-by-step explanation:

Town 1's population is growing at a factor of 1.02 which means that it is increasing by 2% a year.

Town 2 is growing at a factor of 0.999 which means that it is decreasing at a rate of:

= 1 - 0.999

= 0.1%

Town 3's population is increasing by 150 a year and town 4 is 200 people a year.

Town 1 will eclipse them all eventually because it is <u>growing proportionally at 2%</u>.

Towns 3 and 4 will eventually see 150 and 200 people fall below 2% of their town's population which means they will be growing at a slower rate than Town 1.

The half-life of the radioactive element unobtanium-43 is 10 seconds. If 48 grams of unobtanium-43 are initially present, how ma

natka813 [3]

Answer:

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

Step-by-step explanation:

Given;

initial mass of the radioactive element = 48 grams

half life, t = 10 seconds

time of decay (s) remaining mass of the radioactive element

0 ------------------------------------------------- 48 grams

10------------------------------------------------- 24 grams

20 ------------------------------------------------- 12 grams

30 -------------------------------------------------- 6 grams

40 --------------------------------------------------- 3 grams

50 ----------------------------------------------------- 1.5 grams

60------------------------------------------------------0.75 grams

Thus;

At time, 10 seconds, the mass remaining is 24 grams

At time, 20 seconds, the mass remaining is 12 grams

At time, 30 seconds, the mass remaining is 6 grams

At time, 40 seconds, the mass remaining is 3 grams

At time, 50 seconds, the mass remaining is 1.5 grams

HELP±! FAST<br><br>What is the scale factor?

cupoosta [38]

Answer:

$\frac{5}{3}$

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal.

To determine the scale factor calculate the ratio of corresponding sides, that is

$\frac{NO}{GH}$ = $\frac{15}{9}$ = $\frac{5}{3}$
