Answer:

x=5,y=5,z=5

Step-by-step explanation:

x=15-y-z

15-y-z-y+z=5

15-2y=5

y=5

x+y+z=15

15-2y+y+z=15

15-10+5+z=15

z=5

x-y+z=5

x-5+5=5

x=5

List the following objects in order from lowest inertia to highest inertia: Earth, desk, baseball, fork, house, feather,
kirill115 [55]

Answer:

Feather, fork, baseball, desk, cow, tow truck, house, Earth, Sun

Step-by-step explanation:

The bigger the object, the more inertia it has, since it's harder to move a bigger object. So, since a feather is the smallest thing with the least amount mass, it should be the easiest to move, giving it the least amount of inertia. It's the opposite for the Sun, since it's the biggest object on the list.

A triangle has sides with lengths of 7 feet, 15 feet, and 17 feet. is it a right triangle?
aksik [14]
To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.

a^2 + b^2 = c^2

c is the hypotenuse, the longest side of a right triangle.
a and b are the legs of the right triangle.

a = 7
b = 15
c = 17

7^2 + 15^2 = 17^2 ?

49 + 225 = 289 ?

274 ≠ 289

Thus, this triangle is not a right triangle since it does not satisfy the Pythagorean Theorem.

Have an awesome day! :)
