There are 0.015 kilograms in 15 grams. Since each can weighs 0.015 kg and the payment rate is 50p per kilogram, 0.015 multiplied by 66 amounts to 1 kilogram! Therefore, 66 cans are needed to generate one kilogram. As a result, earning £15 would mean that with 2 kg equating to one dollar, then 15 multiplied by 2 equals 30. Consequently, 66 times 30 gives 1980!
66 relates to each kilogram, and 30 indicates how many 50p are required for one dollar!
Thus, to obtain £15, Adam has to recycle a total of 1980 cans!
Response:
- Marti is declared the winner
Step-by-step explanation:
Continuation of question:
- After 10 seconds, the race concluded. The winner is the racer farthest from the starting point. Which car deserves the title of winner? Use mathematical reasoning to support your conclusion.
- Table is attached
Solution
Greg
- Travel speed = 13 ft/s
- Initial position = 30.7 ft from the starting point after 2 seconds
Distance from the starting point after 10 seconds:
30.7 + 13*(10 - 2) = 30.7 + 13*8 = 30.7 + 104 = 134.7 ft
Marti
Travel speed = 16.5 ft/s
- Starting position = 2 ft from the beginning line
Distance from starting point after 10 seconds:
2 + 10*16.5 = 2 + 165 = 167 ft
- In comparing the distances from the start line, 134.7 ft against 167 ft, Marti is further from the start line and is thus declared the winner.
Answer:
How much is the rent? And how many clothes does she want to buy?
Step-by-step explanation:
Greetings!
Let's rewrite the equation:
b = 4c - s².
Plug in your values:
b = 4(25) - (9)²
Now simplify:
4 times 25 equals 100
9 squared equals 81
So, b = 100 - 81
Calculate:
100 minus 81 equals 19
b is 19.
I hope this helps!
