Answer: choice B is true.
Step-by-step explanation:
We are asked to find which value is similar to the value of the expression:
30% of 81.
We know that 30% of 81 could also be represented mathematically as:
30%×81=
which could also be written as:
choice A:
=
Which is not similar to equation (1).
Hence choice A is not similar.
Choice B:
This expression is similar to equation (1).
Hence choice B is true.
Choice C:
Which is not similar to equation (1).
Hence, choice C is not true.
Choice D:
=
Which is not similar to equation (1).
Hence, choice D is not true.
Choice E:
Which is not similar to equation (1).
choice D is not true.
Answer:
an = 1/2 (n) (n+1)
Step-by-step explanation:
1,3,6,10,.........
3-1=2
6-3=3
Each term is different so there is no common difference. It is not an arithmetic sequence
3/1=3
6/3 =2
Each term is different so there is no common ratio. It is not a geometric sequence
1 3 6 10
+2 +3 +4
a1 = 1
a2 = 3
a3 = 6 = 2*3
a4 = 10 = 2*5
You must rewrite the formula for t.
x = t - yz
-t = -x - yz
t = x + yz
