Planet Earth has a mass of kilograms. And although 70% of the Earth's surface is made of water, the water's mass is only percent of the Earth's total mass. Use scientific notation to estimate the mass of the planet's water. In your final answer, include all of your estimates and calculations.

the estimate of the mass of the planet water be

Step-by-step explanation:

The computation of the estimate the mass of the planet's water is given below:

As we know that

The mass of the water would be the percentage of the total mass of the earth

So let us assume the W be the mass of the water

So,

Hence, the estimate of the mass of the planet water be

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
