Answer:
Step-by-step explanation:
Set up the equation:
Since C(t) gives the number of cars purchased in the t-th year after 1998, then make the number of cars equal to 15 000 and solve for t - the year:
20t^2 = 15000
t^2 = 750
t =
The year will be simply 1998 + 5 \sqrt{30}
Answer:
0.1 yards of fabric
Step-by-step explanation:
Data provided in the question:
Number of outfits made for the doll = 14
Fabric used in each outfit = yards of fabric
Starting fabric available = 10 × or
yards
Now,
The total fabric used in making the outfits of 14 dolls
= 14 × yards of fabric
= yards of fabric
Therefore,
The fabric left after making the outfits
= Fabric available in the start - Fabric used in making the outfits
= yards -
yards
= yards
= yards
= yards
= 0.1 yards of fabric
