the male elephant at the city zoo weigh 8,000 pound, which is the same as 4 tons. the female elephant weigh 7,000 pounds. how many tons does she weigh?

3.5 tons

Step-by-step explanation:

Divide the pounds for the male by the amount of tons it is.

8000/4 = 2000

This is how many pounds are in one ton.  Divide the weight of the female by this.

7000/2000 = 3.5

The female weighs 3.5 tons.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
