Answer:Abigail age=32 and Cynthia age=24
Step-by-step explanation:
The long way to compute the sum is to expand each number completely, then add:
3.61 * 10^5 = 3.61 * 100,000 = 361,000
6.05 * 10^6 = 6.05 * 1,000,000 = 6,050,000
Then
3.61 * 10^5 + 6.05 * 10^6 = 6,411,000 = 6.411 * 10^6
A shorter way would be to expand the larger of the two numbers until the powers of 10 match up, then add:
6.05 * 10^6 = 60.5 * 10^5
Then
3.61 * 10^5 + 60.5 * 10^5 = (3.61 + 60.5) * 10^5 = 64.11 * 10^5 = 6.411 * 10^6
Answer:
48
Step-by-step explanation:
given that c = 5 and d = 4?
so insert the value of c and d equals 5 and 4 respectively
6c2 – 5d + 8
6 (5) × 2 - 5 (4) + 8
30 × 2 - 20 + 8
60 - 20 + 8
40 + 8
48
To find the number divide 14 by 70%
14/0.70 = 20
The number is 20
The answer would be three
