Ratio-Proportion is the answer
Answer:
5002
Step-by-step explanation:
The given series is an arithmetic progression with
a = the first term
d = common difference
n = number of terms
S = the sum of the nth term
Recall that
S = n/2(2a + (n-1)d)
As such,
a = 2
d = 8 -2 = 14 - 8 = 6
n = 41
Hence
S = 41/2(2*2 + (41 - 1)6)
= 41/2 ( 4+ 240)
= 41 * 244/2
= 5002
ANSWER
0.1
EXPLANATION
We want to estimate the quotient of 1.64 ÷ 22.
To do this, we will approximate the two numbers to whole number and solve it.
It becomes:
2 ÷ 20
That is:
Note: since 2 cannot be divided by 20, we write 0. and add a 0 to the back of 2.
The estimate of the quotient is 0.1.
Answer:
When you round 490.625 to the nearest tenth its 490.6.
