Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin=\$ 168

10 snorkel and 12 pairs of fin

Let the cost to  rent a snorkel be =\$x

and cost of a pair of fin is =\$y

x=3y            (given condition)

10x+12y=168

10\times 3y+12y=168

30y+12y=168

42y=168

y=168/42

y=4

Cost of a pair of fin=  y=\$ 4

x=3y

x=3\times 4

x=12

Cost of rent a snorkel=\$ 12

Total cost of a rent snorkel

9. Find the length of a base of a triangle with<br>an Area of 100 and a height of 25.​
liraira [26]

Answer:

8 (units)

Step-by-step explanation:

The formula to find the area of a triangle is A = 1/2(b*h). Since we know the area already, we can substitute that value in to calculate the answer backwards.

Plug in the numbers known:

A = 100

h = 25

Equation: 100 = 1/2(b*25)

Now solve:

100 = 1/2(b*25)

200 = b * 25

<em>8 = b</em>

So, the answer to your question is 8 (units).

Hope this helps!
