Use the recursive formula to find the first five terms in the arithmetic sequence: f(1)=8
f(n)=f(n-1)+10
a.) 8, 18, 28, 38, 48 b.) 8, 13, 18, 23, 28
c.) 10, 20, 30, 40, 50 d.) 18, 28, 38, 48, 58

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
