Answer:
Step-by-step explanation:
For two polygons to be considered similar, the corresponding angles need to be congruent and at the same time, the corresponding sides sides need to be proportional.
The corresponding side of QR is BC
BC = 2 and QR = 12
As you can see QR is 6 times longer than BC and so PQ should be proportional to AB by the same factor.
if AB is 4 then multiply that by 6:
4 x 6 = 24
Line PQ is 24
Answer:
y=-2x+13
Step-by-step explanation:
Slope-intercept form of a line is y=mx+b where m is slope and b is y-intercept.
The slope of y=-2x-2 is -2 since m=-2.
A line that is parallel to the given line is going to have the same slope.
So we already know the equation we are looking for should be in the form y=-2x+b.
We just to need to find b.
We can use the given point on our line do that.
5=-2(4)+b
5=-8+b
8+5=b
13=b
So the equation is y=-2x+13.
Answer: (E) Not necessarily, because this wasn't an experiment
Step-by-step explanation:
As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.
An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.
keep dividing by the prime numbers is ascending order 2, 3 5 ....... ( if they are factors) , of course) until you end up with a prime number:-
80 / 2 = 40
40 / 2 = 20
20 / 2 = 10
10 / 2 = 5
So 80 = 2*2*2*2*5
