Answer:

16683 candies

Step-by-step explanation:

Given:

Initial value is 45000.
Reduction per day is 18%.

The equation would be:

$C(t) = 45000*(1 - 0.18)^t=45000*0.82^t$ , where C(t) is the number of candies left after t days

Find the value of C(5):

C(5) = 45000*0.82⁵ ≈ 16683 rounded

1) 0.00274

2) 0.872

3) 0.00240

Step-by-step explanation:

1) 365/(365×365) = 1/365

= 0.002739726027

= 0.00274 (3 sf)

2) (364/365)^50

= 0.8718182573

= 0.872 (3 sf)

3) [365 × (364^48)]/(365^50)

= 0.002401685062

= 0.00240 (3 sf)

The speed of an airplane is 885 km per hour. Find the distance covered by the airplane in 3 hours and 20 minutes. Also, express

torisob [31]

Answer:

$2.95\cdot 10^3\:\mathrm{km}$

Step-by-step explanation:

Distance is given by $D=st$ , where $s$ represents speed or rate and $t$ represents time.

What we're given:

speed of $885\:\mathrm{km/h}$
time of $3.\overline{3}$ hours

Thus, the distance covered by the airplane is:

$d=885\cdot 3.\overline{3}=2,950\:\mathrm{km}$

In scientific notation:

$2,950\:\mathrm{km}\implies\boxed{2.95\cdot 10^3\:\mathrm{km}}$
