Answer:
$14.4
Step-by-step explanation:
20%= .2
$18 x .2 = $3.60
$18 - $3.6 = $14.4
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.
The value of x in the expression, x 2 = 9 is 4.5
9 divided by 2 = 4.5
The 5 is in the hundreds place so the value of the 5 is 500.
Subtracting 1 from 5 the number becomes 4 ( 5-1 = 4) which would mean the new value would be 400
The answer is b. 400
