Answer:
A.
Step-by-step explanation:
Since VA and BC are equal in length so their central angles would also be equal.
So
<VWA = <BWC
32x-27 = 120
32x = 120+27
32x = 147
Dividing both sides by 32
x ≈ 4.6
unit rate of speed is 0.27 miles per minute .
<u>Step-by-step explanation:</u>
Here we have , it took marjorie 15 minutes to drive from her house to her daughter's school. If the school was 4 miles away from her house, We need to find what was her unit rate of speed . Let's find out:
We know that , ...........(1)
According to question we have following parameters as :
Putting these value in equation (1) we get:
⇒
⇒
⇒
⇒
Therefore , unit rate of speed is 0.27 miles per minute .
The missing justification is the Subtraction property of equality.
This is because to get 1/3x=4, you need to subtract 3 from both sides.
In order for it to be a square, we see that it has to have a distance of 3 from the points B and C, since the distance between A and B is 3. A square is a parallelogram, so AD needs to be parallel to BC. Hence, since the vector BC is (0,3), we have that the vector AD is also (0,3). So, adding the coordinates of the vector to A, we get that D=(0,3).
Step-by-step explanation:
(a^2+3b)/(c-2d)
substitute a=3,b=8,c=2,d=5
(3^2+3(8))/(2-2(5))
=(9+24)/(2-10)
=33/(-8)
=-4.125
