Triangle abc is dilated by a scale factor of 0.5 with the origin as the center of dilation, resulting in the image triangle a'b'c'. if a=(2,2), b=(4,3), and c=(6,3), what is the length of bar (b'c')

1 units

Step-by-step explanation:

Given : Triangle ABC is dilated with the origin as the center of dilation, resulting in the image triangle A'B'C'.

The scale factor dilation (k) = 0.5

To find the length of , first we need to calculate the distance from B to C or

If B=(4,3), and C=(6,3), then , by using distance formula

Now, the length of B'C' = units

Hence, the length of B'C' = 1 units

the correct answer is 1: 2

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
