Answer:
75 km
Step-by-step explanation:
Given the following :
Scale on first map = 1cm to 20 km
Distance fromFresno to San Francisco = 15km on first map
Scale on 2nd map = 1cm to 100 km
1cm / 20km = 15km
Let of Distance from Fresno to San Francisco on 2nd map = d
1cm / 100km = d
1 : 20 = 15
1 : 100 = d
20/ 100 = 15/d
1/5 = 15/d
d = 15 * 5
d = 75 km
Answer:
The certificate will be worth $5,559.92 on Ruth's 19th birthday.
Step-by-step explanation:
The compound interest formula is given by:

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:

So


The certificate will be worth $5,559.92 on Ruth's 19th birthday.
