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: 3/10 of a mile
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the 2/5 of the way that she travelled on her bike before it broke by the total distance (3/4 of a mile)
2/5 x 3/4 = 3/10 of a mile
She travelled 3/10 of a mile on her bike before it broke
Feel free to ask for more if needed or if you did not understand something.
The volume equation for a cylinder is V=(pi)(di^2)(h)/4, so in this problem it is V=pi(8^2)(10)/4 --> V=pi(64)(10)/4 --> V=pi(640)/4 --> V=160pi or 502.65
Answer:
n + 25 = 100
n = 75
Step-by-step explanation:
When you write an equation for what's given, you get n + 25 = 100.
Then you do some simple math and subtract 25 from 100 to find n. Or 75.
