Agroup of tourists spends $156 to rent snorkels and fins. a total of 15 snorkels and 18 pairs of fins are rented. renting a snorkel costs four times as much as renting a pair of fins. how much does it cost to rent a snorkel?

At any given time, the amount of money in a club's bank account will equal the starting amount plus the amount saved each week. We can set up an equation for each club that adds these two parts together to give us that total:

$ saved up by each club after X weeks = starting $ + ($ saved per week)*(X number of weeks)

For each club, here are the equations we need:

Total $ Saved by Science Club after X weeks = 20 + 10X
Total $ Saved by Music Club after X weeks = 50 + 5X
Total $ Saved by Math Club after X weeks = 0 + 15X

We can use "Y" to represent the total $ saved by each club:

Ysci = 20 + 10X

Ymus = 50 + 5X

Ymath = 15X

To find all the possible times when any two clubs will have saved the same amount of money, we just need to graph these three equations and find the points where each pair of lines intersect. After graphing the equations, we're looking for the X-values for the intersection points where:

1) Ysci = Ymus

(The point at which 20 + 10X = 50 + 5X)

2) Ysci = Ymath

(The point at which 20 + 10X = 15X)

Ymus = Ymath

(The point at which 50 + 5X = 15X)

We can check the graphing solution by solving these pairs of equations with algebra. We just combine all "X" terms on one side and all number terms on the other side to solve for X.

1) Ysci = Ymus

20 + 10X = 50 + 5X

5X = 30

X = 6

2) Ysci = Ymath

20 + 10X = 15X

20 = 5X

X = 4

Ymus = Ymath

50 + 5X = 15X

50 = 10X

X = 5

Answer Summary:
1) $ saved by Science Club = $ saved by Music Club after 6 weeks;
2) $ saved by Science Club = $ saved by Math Club after 4 weeks;
3) $ saved by Music Club = $ saved by Math Club after 5 weeks.

the answer is 45 i just did it on oddesy ware

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
