Yes, by the time you add up all estimations, you must add taxes.
Divide 28 by 3 and count how many are left over.
28 / 3 = 9 1/3
So each boy had 9 toy cars, and because you can't have 1/3 cars, you round 1/3 to 1. So there was 1 left over car.
Answer:
2.5
Step-by-step explanation:
A triangle ABC with vertices A(0, 0), B(0, 4), and C(6, 0) is dilated to form a triangle A'B'C' with vertices A′(0, 0), B′(0, 10), and C′(15, 0). If the center of dilation is point A or A' (the origin), then
![\dfrac{A'B'}{AB}=\dfrac{A'C'}{AC}.](https://tex.z-dn.net/?f=%5Cdfrac%7BA%27B%27%7D%7BAB%7D%3D%5Cdfrac%7BA%27C%27%7D%7BAC%7D.)
Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is
![k=\dfrac{10}{4}=\dfrac{15}{6}=2.5.](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B10%7D%7B4%7D%3D%5Cdfrac%7B15%7D%7B6%7D%3D2.5.)

Step-by-step explanation:
Answer:
Option C. 50 square centimeters
Step-by-step explanation:
we know that
The surface area is equal to the area of four triangles plus the area of rectangle
so
![SA=2[\frac{1}{2}(4)(2)]+2[\frac{1}{2}(6)(3)]+(6)(4)](https://tex.z-dn.net/?f=SA%3D2%5B%5Cfrac%7B1%7D%7B2%7D%284%29%282%29%5D%2B2%5B%5Cfrac%7B1%7D%7B2%7D%286%29%283%29%5D%2B%286%29%284%29)
![SA=8+18+24](https://tex.z-dn.net/?f=SA%3D8%2B18%2B24)
![SA=50\ cm^{2}](https://tex.z-dn.net/?f=SA%3D50%5C%20cm%5E%7B2%7D)
