The rate (or speed) of the tortoise is 27 miles/year. At 10 years,
(27 miles/year)*(10 years) = 270 miles
Answer:
446.75 y^2
Step-by-step explanation:
First, Kelly found the area of a circle, not half a circle, which is on top of the figure. She also shouldn't have subtracted the area of the circle by the airea of the base, as she is trying to find the area of the ENTIRE figure.
.5 TIMES pi times 9^2 = 122.75
the second part, calculating the square base is correct..
122.75+324 = 446.75 y^2
The answer is 21
the area of the small rectangle is 6 and the area of the bigger one is 15
15+6=21
Okay, (Assuming this is workings, dunno if it's the right method) multiply the bottom equation by -4 (for simplicity's sake here) so you get -4x+12y=12. (Changing the signs here) then to get rid of the x in the equation, add the two together.
4x-2y=8
+
-4x+12y=12
=
10y=20
Divide 20 by 10 to get y=2. then put the answer for y back into one of the equations.
x- 3(2)=-3
x-6=-3
x=3
in sum, y=2 and x=3.
That is how it's done, hope it helps:)
