r=0.25 miles
l=2×

×0.25
=0.5 × 3.14
=1.57
120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes

Answer:
d. 463246.7
Step-by-step explanation:
V=4
/3πr^3=4/3·π·48^3≈463246.7
If 100 miles = 1 in.
650 = 6.5 x 100 and 6.5 x 1 = 6.5
so, if the journey is 650 m...... the map is 6.5 in.
Answer:
Principal = 3500
Time = 8 years
We are given that compound quarterly
So, No. of compounds per year = 2
Rate of interest = 5%
Formula : 
Substitute the values :


Interest = 3863.345 - 3500 = 363.345
Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345
