Answer:

250 ft.

Step-by-step explanation:

It seems that you are learning the side-splitter theorem right now. If a line is parallel to one side of the triangle and intersects the other two sides, it divides the side proportionally. From the picture we can tell that the streets are parallel, with a line of intersection. Therefore, we can create the following equation of proportionality:

$\frac{375}{300} = \frac{x}{200}$

Now that we have this equation, we can use the butterfly method to solve for x. We cross multiply:

$375*200=300x\\$

Now, all we have to do is isolate the variable to find x:

$75000=300x\\x=250$

Therefore, the distance of Orange Ave between the 3rd St. and 4th St. is 250 ft.

I hope this helps! Please let me know if you have any further questions :)

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:

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