Answer:
The scaling factor is 4.
Step-by-step explanation:
To find the scaling factor from A to B, we must know that these are similar triangles. Since this is not stated in the problem, we will assume these are similar triangles.
Similar triangles simply have the same scaling ratio, allowing for any size triangle to be created with the same relative dimensions. With this in mind, let's check to see the multiple of each side by simply taking the sides of the triangle B divided by the sides of triangle A.
40 / 10 = 4
44 / 11 = 4
72 / 18 = 4
Notice how each of the sides from triangle B to triangle A has the same multiple, 4. This tells us that the scale from A to B is 4.
Hence, the scaling factor is 4.
Cheers.
Answer:
$309.01
Step-by-step explanation:
To calculate tax, you need to turn the percent to a decimal. This is done by moving the decimal point two spaces to the left, adding zeros and needed.
4.75% = 0.0475
Now take the price of the bike, 295, and multiply it by 0.0475.
295 x 0.0475 = 14.0125
All you need are the first two numbers after the decimal point since you are dealing with money.
Add the product, 14.01, to the price of the bike, 295, and you have your answer.
$309.01

Answer:
39.25
Step-by-step explanation:
Area of the shaded part= Area of the Square - Area of the Triangle
Area of the Triangle= b*h/2= 2*3/2= 3
Area of the Square= side²= (6.5)²= 42.25
Area of the shaded part= 42.25 - 3= 39.25
