Answer:
Option B
Step-by-step explanation:
Given that the point A(4,6) is dilated with a scale factor of 2
about the point O(2,1) as centre of dilation
This implies that the new point A' will lie on the lineOA with distance equal to double of OA.
Or A will be the mid point of OA' and AA' will have same slope as OA
Considering the above two conditions we find that
Option A cannot be right.
Option B: Midpoint of OA' = (4,6) matches with given
Slope of AA'=
= slope of OA
Thus option B satisfies both
So answer is B
1/4 yard. There isn't much more of a way to explain it. Its just remembrance for this
Answer:
you have the answer correct actually

It is really good but I think you have to ask you mom
Answer: P = 0.125 = 1/8
Step-by-step explanation:
We know that he has a blue coat and a black coat.
If he dresses at random, then the probability of getting the blue coat is equal to the quotient between the number of blue coats (1) and the total number of coats (2).
Then the probability is:
p = 1/2
We also know that he has blue pants and brown pants, the probability of getting at random the blue pants is calculated in the same way than above, then:
q = 1/2
And for the shirt he has a blue shirt and a red one, the probability of randomly selecting the blue one is calculated in the same way than above, then:
k = 1/2
Now, the joint probability (he selects all blue clothes) is equal to the product of the individual probabilities:
P = p*q*k = (1/2)*(1/2)*(1/2) = 1/8 = 0.125
