Answer:
1) 250 meters= 0.25 km
2) 12 meters= 0.012km
3) 1 meter= 0.001 km
The constant of proportionality is 1000 meters in 1km (1000 meters)
I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!
Answer:
growth because 'b' > 1 b decay because 'b' is < 1
Second one is a
im pretty sure
7x7=49 and 8x8=64
Answer:
Step-by-step explanation:
Let q represent the number of quarters. Then Tony's coin value is ...
0.25q +0.10(25 -q) = 4.00
0.15q +2.50 = 4.00 . . . . . . . . eliminate parentheses, collect terms
0.15q = 1.50 . . . . . . . . . . . . . . subtract 2.50
q = 10 . . . . . . . . . . . . . . . . . . . . divide by the coefficient of q
Then the number of dimes is ...
25 -10 = 15
Tony has 15 dimes and 10 quarters.
