Answer:
C(m) = 0.10x + 41
Step-by-step explanation:
C(m) = 0.10m + 41
Answer: 10y + 1
Step-by-step explanation:
The perimeter is the total distance round the figure.
Now, in this case it is going to be
Perimeter = 3y + 5 + 6y + y - 4
= 3y + 6y + y + 5 - 4
= 10y + 1
The answer Is 3.482 × 10^9
Answer:
The scale factor of triangle ABC to triangle RST is 1/3
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ----> the scale factor
To find the scale factor divide the length side of the image (reduced triangle) by the corresponding length side of the pre-image (original triangle)
![z=\frac{RS}{AB}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BRS%7D%7BAB%7D)
substitute the values
![z=\frac{6}{18}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B6%7D%7B18%7D)
simplify
![z=\frac{1}{3}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B1%7D%7B3%7D)
The scale factor is less than 1
so
Is a reduction
