Answer:
$300
Step-by-step explanation:
90 x 2 = 180
60 x 2 = 120
120 + 180 = 300
Ans:- 4:12:24
first add the ratios,that is =10
Then find the amount the 1st person payed= 1/10 *40
=4
2nd person payed= 3/10*40=12
3rd person payed= 6/10*40=24
therefore your answer is 4:12:24
can you also answer my question
Answer:
Common difference = 11
Second term is -1
fourth term is 21
Step-by-step explanation:
Given:
The given sequence are.
-12, __, 10, __, 32, 43
We need to find common difference and missing terms of the given sequence.
Solution:
The difference between two consecutive number of the sequence is called common difference.
The consecutive number of the given series are 32, 43
So, the common difference is
common difference = 11
Therefore, the common difference of the given series is 11.
Now, we add first term and common difference for the first missing number of the sequence.
= -12 +11
= -1
So, the second term of the given sequence is -1.
Similarly, we add third term and common difference for the fourth missing number of the sequence.
= 10 + 11
= 21
So, the fourth term of the given sequence is 21.
Therefore, the complete sequence is given below.
-12, -1, 10, 21, 32, 43
