Answer:

a) 36°

b ) 18°

Step-by-step explanation:

The formula is given as:

The measure of each exterior angle =360°/n, where n = number of sides of a polygon.

a) decagon

Decagon = 10 sides

Hence, the measure of each exterior angle = 360°/10

= 36°

b) 20-gon

20-gon = 20 sides

Hence, the measure of each exterior angle = 360°/20

= 18°

Value of peters house has risen 20% a year for the last three years. If the value of peters home three years ago was $120 thousa
notka56 [123]

Answer:

The value now = $207,360

Step-by-step explanation:

Rate of increase = 20% per year = 20/100 = 0.2 per year

value 3 years ago = $120,000

interest at year 1:

20% of 120,000

= 0.2 × 120,000 = 24,000

Value at the end of year 1

= initial value + interest

= 120,000 + 24,000 = $144,000

In year 2:

20% of 144,000

= 0.2 × 144,000 = 28,800

Value at the end of year 2:

144,000 + 28,800 = $172,800

In year 3

0.2 × 172,800 = 34,560

Value at the end of year 3:

34,560 + 172,800 = $207,360

How many times larger then 2x10² is 2x10⁸​
Brrunno [24]

Answer:

1,000,000 times larger

Step-by-step explanation:

2 x 10^{8} = 200,000,000

2 x 10^{2} = 200

200,000,000 divided by 200 is 1,000,000

It can also be solved by subtracting the exponents from 10. Then dividing the two number being put the scientific notation.

10^{8} - 10^{2} = 10^{6

2 ÷ 2 = 1

Now solve:

1 x 10^{6 = 1,000,000
