Answer:
No coz 2:3 is 2+3=5
1:2 is 1+2=3 so they are not equivalent.
The answer is c. forgive me if i am wrong
The equation to model this would be 65 = 11r + 9s.
In this equation, we know that the total number he works is 65. We also know he burns 11 every time he runs for an hour. Therefore we can multiply 11 by r. We also know he burns 9 for every hour he spends swimming. Therefore we can multiply 9 by s.
When we put all three of these things together, we get 65 = 11r + 9s.
Answer:
3 days: 8 heads.
10 days: 1024 heads.
Step-by-step explanation:
If each time the hero cuts off all the heads, then the amount doubles each time. This can also be represented using powers of 2, with 2^n, where n is the number of days.
2^1 = 2, so two heads the first time he cuts it.
2^2 = 4, so four heads the second time he cuts it.
With three, 2^3 is 8 so there are 8 heads.
With ten, 2^10 is 1024 so there are 1024 heads.
Answer:
None of those is right
But if you have to put something then try A and B
Step-by-step explanation:
Here's the right answer for each equation
A. 100
B. 1000
C. 1000
D. 10000
E. 100
So if the question was to select each equation that the number 100 makes true.
Then the answers would have been A and E
Hope this helps, have a beautiful day
