Answer:
a) NT = 8
b) RS = 8
c) RT = 16
d) ZR = 24
Step-by-step explanation:
All of the marked sides are congruent. (That's what the marks mean.) It might help you to put 8 next to each hash mark like it is on NS. So, you have ...
NT = RS = ST = TZ = NS = 8
Segments on the same line sum, so ...
RT = RS +ST = 2RS = 16
ZR = RS +ST +TZ = 3RS = 24
a) NT = 8
b) RS = 8
c) RT = 16
d) ZR = 24
Without knowing anything about the sequence, this is impossible to answer. But suppose the sequence is arithmetic, in which case each term differs by some constant :
Then we can write
and from the formula above, we see this means the 10th term in the sequence is . But that's all the specific info we can gather about such an arithmetic sequence. If we set the first term to be some unknown , then the sum of the first 19 terms in the sequence would be
If we knew one more term in the sequence, we could determine the value of and derive the value of (if the first term is not immediately given), and then go on to find an exact numeric value for the sum.
The answer is A because the median is the middle number (4) in an ascending or descending list of numbers and the mean is 3 because if you take the four numbers above 0 you get the total then divide the total by how many numbers there are you get your mean and 15 divided by 5 is 3. Hopefully this helped if not I can explain a little more if you need it!!
24/0.20 = 120 . . . . . divide by the coefficient
ANSWER: 120
Answer:
The solution is (0,4).
Step-by-step explanation:
We are given the following system of equations:
Solving by substitution.
In the first equation, we have that:
Replacing in the second equation:
Multiplying everything by 7
Now, with y, we can find x.
So the solution is (0,4).
