Answer:
Sale Price = $36
Step-by-step explanation:
To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.
Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36
So 8 meals for $10 each , 2 tickets for $45 each, and 2 jerseys for $65 each
So (8x10) + (2x45) + (2x65) is the equation
And the answer is $300 because 8x10 is 80, 2x45 is 90, 2x65 is 130 and if you add it all up you'll get $300
80 + 90 = 170 + 130 = 300
Hope this helps! :)

Step-by-step explanation:
- 6,2 × 10² = 0 × t + ½ × (-9/8) × t² + 2582,91
- 6,2 × 100 = 0 + ½ × (-9/8) × t × t + 2582,91
- 620 = ½ × (-9/8) × t × t + 2582,91
- 620 = (-9/16) × t × t + 2582,91
- 620 = (-9/16 t²) + 2582,91
- 6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91
Conclusion:
6,2 × 10² ≠ 0 × t + ½ × (-9/8) × t² + 2582,91
When you have to describe a 3D shape you have to keep the following definitions in mind:
<em>1. The face of a 3D shape is a flat surface.</em>
The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.
<em />
<em>2. The edge is where two faces meet.</em>
For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.
<em>3. The vertex is a corner, where the edges meet.</em>
There are three vertices on each end of the shape, so it has a total of 6 vertices.
A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.
so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.
the diameter of that circle is 10, so its radius is half that, or 5.
