Answer:

60 marbles

Step-by-step explanation:

Given:  24 red marbles is 40% of how many marbles

Let number of marbles be x

"24 red marbles is 40% of how many marbles"

             24 = 40% of x

solve for x

First change % to decimal

    24 = 0.40x

Division property of equality, divide by 0.04 both sides

     x = 24÷0.40

     x = 60

Hence, 40% of 60 is 24

The area of the surface of a sphere is described by the formula S=4(3.14)r^2. The earth has a radius of 3960 miles and dry land
Stella [2.4K]

Answer: 57,512,581.63miles^2

Step-by-step explanation:

Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

S=4(3.14)r^2\\S=4(3.14)(3,960miles)^2\\S=196,960,896miles^2

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by \frac{29.2}{100}=0.292

Threfore, the area of dry land is the following:

S_{land}=(0.292)(196,960,896miles^2)=57,512,581.63miles^2
