Answer:
The correct option is A) Q and W are similar but not congruent.
Step-by-step explanation:
Consider the provided graph.
Figure Q is a quadrilateral with sides measuring 5 and 2
Figure S is a quadrilateral with sides measuring 5 and 2.
Figure W is a quadrilateral with sides measuring 10 and 4.
Two figures are similar if the shape of the figures are same but not necessarily same size.
Two figures are congruent if the size and shape of the figure are same.
Note: If two figures are congruent, then they are also similar, but converse is not true.
The dimensions of Q is equals to the corresponding dimensions of the rectangle S. Thus, Q and S are similar and congruent as they have the same shape and the same size.
The dimension of quadrilateral W is 2 times of quadrilateral Q and S. Thus the dimensions of W is proportional to dimensions of Q.
That means quadrilateral W is similar to Q and S but not congruent.
Thus, the correct option is A) Q and W are similar but not congruent.

I took the liberty of finding for the complete question.
And here I believe that the problem asks for the half life of Curium. Assuming
that the radioactive decay of Curium is of 1st order, therefore the
rate equation is in the form of:
A = Ao e^(-kt)
where,
A = amount after t years = 2755
Ao = initial amount = 3312
k = rate constant
t = number of years passed = 6
Therefore the rate constant is:
2755/3312 = e^(-6k)
-6k = ln (2755/3312)
k = 0.0307/yr
The half life, t’, can be calculated using the formula:
t’ = ln 2 / k
Substituting the value of k:
t’ = ln 2 / 0.0307
t’ = 22.586 years
or
t’ = 22.6 years
Answer:8,400 miles
Step-by-step explanation: You would do 2,100•4 because you are driving 2,100 miles a week and there are 4 weeks you would have to times the amount of miles by how many weeks
Answer:
b = 10
Step-by-step explanation:
P = 2 (l + b)
l = 15
P = 50
Substitute
50 = 2 (15 + b)
multiply
50 = 30 + 2b
subtract
20 = 2b
divide
b = 10
