$\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}$

$\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}$

$\text {Difference = }5.97 \times 10^{24} - 4.87 \times 10^{24}$

$\text {Difference = }(5.97 - 4.87) \times 10^{24}$

$\text {Difference = }1.1 \times 10^{24} \text { kg}$

--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24}
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg

Ostrovityanka [42]

Answer:

Number of algae in 7 days = 70.355

Step-by-step explanation:

Given:

Algae in beginning = 50

Rate of increasing = 5% per day = 0.05

Number of days = 7 days

Find:

Number of algae in 7 days.

Computation:

$Number\ of\ algae\ in\ 7\ days = Algae\ in\ beginning(1+Rate\ of\ increasing)^{Number\ of\ days}\\\\Number\ of\ algae\ in\ 7\ days = 50(1+0.05)^7\\\\Number\ of\ algae\ in\ 7\ days = 70.355$
