1200= 80%
? =100%
to find the ? you can multiply 100(1200)=120000
then 120000 divided by 80= 1500
the original price was 1500, with the discount of 20% you save 300$ and the price is 1200$

The sum of the area of these three rectangles will be 3x² + 20x.
<h3>What is the area of the rectangle?</h3>
Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The lengths and the widths of the following three rectangles are labeled.
The area of the first rectangle will be
A₁ = x · x
A₁ = x² square units
The area of the second rectangle will be
A₂ = 20 · x
A₂ = 20x
The area of the third rectangle will be
A₃ = 2x · x
A₃ = 2x²
Then the sum of the area of these three rectangles will be
A = A₁ + A₂ + A₃
A = x² + 20x + 2x²
A = 3x² + 20x
Thus, the sum of the area of these three rectangles will be 3x² + 20x.

Answer:
Step-by-step explanation:
3D space (x, y, z) = (10, 45, 57)
I will use x² + y² = (2D Hyp)² and (2D Hyp)² + z² = (3D Hyp)²
which is just x² + y² + z² = (3D Hyp)²
10² + 45² + 57² = (3D Hyp)²
100 + 2025 + 3249 = 5374 = (3D Hyp)² the destance from the origin
= 73.31 the destance from the origin
The radius of can is 2.524 inches
<em><u>Solution:</u></em>
Given that large can of tuna fish that has a volume of 66 cubic inches and a height of 3.3 inches
To find: Radius
Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,
<em><u>The volume of cylinder is given as:</u></em>
Where,
"r" is the radius of cylinder
"h" is the height of cylinder
is a constant equal to 3.14
Substituting the given values in above formula,
Thus the radius of can is 2.524 inches
