Answer:
1 : 2000000
Step-by-step explanation:
we have to convert 20km into cm so
20km×100000
=2000000
So ratio is 1:2000000

Answer:
Step-by-step explanation:
<u>You need to find the difference:</u>
- 17.50x + 25 - (8.50x + 3) =
- 17.50x - 8.50x + 25 - 3 =
- 9x + 22
Correct one is B
Answer:
4) 40 Square inches
Step-by-step explanation:
You do 2 x 4 then divide by 2. after that you multiply by 4. Then you add the square which is 2 x 2
Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
