Write the proportion 20/100 = x/20

Now multiply 20 x 20.

You get 400

Now divide it by 100.

You get 4

20% of 20 is 4.

Answer:

$24(f(n))$

Step-by-step explanation:

$f(n+3) = 3^{n+3}\\f(n+1) = 3^{n+1}$

$f(n+3) - f(n+1) = 3^{n+3} - 3^{n+1}$

$= 27(3^n) - 3(3^n)$

$= 24(3^n)$

$= 24(f(n))$

hope this helped! :)

I’ve done question a. But can you help me on b and c

spin [16.1K]

Answer:

Step-by-step explanation:

b) Diameter of Mercury = 4.88 * 10³ = 4.88 * 1000 = 4880 km

Radius of Mercury = 4880÷ 2 = 2440 km

c) Mass of Jupiter = 1.898 * 10²⁷ = 18.98 * 10²⁶

Mass of Saturn = 5.68 * 10²⁶

Difference = 18.98 * 10²⁶ - 5.68*10²⁶

= (18.98 - 5.68) * 10²⁶

= 13.30 * 10²⁶

= 1.330 * 10²⁷
