$5.50 x 2 is $11.00
$2.50 x 2 is $5.00
$11 plus $5 is $16
it costs $16 to rent a pair of skates for 4 hours
Answer:
Step-by-step explanation:
Let the number of months be x
Alligator 1 weight = 4 + 2x
Alligator 2 weight = 8 + x
- 4 + 2x = 8 + x
- 2x - x = 8 - 4
- x = 4
The answer is 4 months
Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
So the three sides of the triangle are
15, 8 and 17

*The underlined problems is what you do first*
1. BC = 9 tan 45 = 9 ft
AC = 9 tan 60 = 9 sqrt(3) ft
AB = AC - BC = 9sqrt3 - 9 ft ~ 6.59 ft
2. G-Zoo = 200sqrt3 / tan 60 = 200 ft
G-Library = 200sqrt3 / tan 30 = 600 ft
Zoo-Library = G-Library - G-Zoo = 600 - 200 = 400 ft
