Answer:
a) Set up triangles where the hypotenuse is 16ft (the ladder) and one of the two edges are 1, 2, 3, 4, 5ft (the base of the ladder). Use a^2 + b^2 = c^2 where a is the base length, c is the hypotenuse and b is the value you are trying to find.
Ex w/ 1ft base:
1^2 + b^2 = 16^2
1 + b^2 = 256
b^2 = 255
b = 15.97ft.
b) Simply take your answers from part a) and add 5.5ft (the height of the girl) to them.
Ex w/ 1ft base:
15.97ft + 5.5ft = 21.47ft
c) Using logic here think about it. Let's take the 1ft base as the example. Marissa standing on top of the ladder is 21.47ft. That's clearly not high enough to reach the cat . . . but what happens if Marissa reaches upwards. As long as her arms can reach roughly 1.53ft above her head she should be able to reach it.

She will have about 3 minutes 20 seconds to work on each exercise because 1/3 of an hour is 20 minutes. You can find that by dividing 60 by 3. Next you have to divided 20 by 6. Your answer will be 3.33333333333. So you would get about 3 minutes 20 seconds
Answer:
( x - 2 ) ( x + 2 ) ( x² + 4 ) - ( x² - 2 ) ( x² + 3 )
(x²– 4) (x²+4) – (x⁴ + x² – 6)
( x⁴ – 16 ) – ( x⁴ + x² – 6 )
( x⁴ – 16 ) + ( – x⁴ – x² + 6 )
– x² – 10
I hope I helped you^_^
Well, if you are talking how much she can swim per minute, you have to divide 1700 by 40 to get the unit per minute, 1700 being the meters she can swim, and 40 are the minutes she takes to swim. So, 1700 divided by 40 would be 42.5 meters per minute. So Angela's unit is 42.5 meters per minute. YOU'RE WELCOME :D
