Answer:

x = 85

Step-by-step explanation:

The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,

a^2 + b^2 = c^2

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.

Substitute in the given values and solve,

13^2 + 84^2 - x^2\\\\169 + 7056 = x^2\\\\7225 = x^2\\\\85 = x

8090 [49]
V=(4/3)pir^3
find smaller
V=(4/3)pi8^3
V=(4/3)pi512
V=(2048/3)pi

twice of that
Vbig=2*(2048/3)pi
Vbig=(4096/3)pi
find radius
(4096/3)pi=(4/3)pir^3
divide both sides by pi
(4096/3)=(4/3)r^3
times both sides by 3
4096=4r^3
divide both sides by 4
1024=r^3
cube root both sides
8∛2=r

I see the amount was $90.00 then reduced to $<br>75.00 , what is the percent ?
VashaNatasha [74]

Answer:

16 2/3 %

Step-by-step explanation:

Since the price went down, we are find the percent decrease.

Percent decrease = (original price - new price)/ original price

                               = (90 - 75)/90

                                =15/90

                                  .1666666666666

Changing to percent form

                                      16.6666666666666666666666%

                                       16 2/3 %
