Answer:
≈ 12.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the third side, then
x² + 6² = 14²
x² + 36 = 196 ( subtract 36 from both sides )
x² = 160 ( take the square root of both sides )
x = 
≈ 12.6 ( to the nearest tenth )
Answer:
Step-by-step explanation:
~
6x + 4y = 800
-6x -6x
--------------------
4y = -6x + 800
÷4 ÷4 ÷4
---------------------
y = -6/4x + 200
First subtract, then divide, and then you have it. 6/4 is your slope. Your rise is -6 and your run is 4.
Answer:
- Mass
- Surface area
- Volume
Step-by-step explanation:
The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object
<u>Mass </u>
A property of a physical body and a measure of its resistance to acceleration when a net force is applied.
<u>Surface </u>
The area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
<u>Volume </u>
The Measure of the amount of space that a substance or an object takes up.
