Answer:
in 7 days level of water changed in lake= -28
the water level change each day= -28/7= -4cm
Step-by-step explanation:
To get the area of the half circle, do π r².
Let's use 3.14 as pi.
First square 2 to get 4 then multiply it by 3.14 to get 12.56. Since this is a half circle we have to divide it by 2 for the area: 6.28.
Then for the triangle multiply 6 times 2 (12) then divide it by 2 to get 6. Then add the two together to get 12.28 then round to the nearest tenth to get a final answer of 12.3 m². Hope this helps!
Your equation is x + (3+2x) + (2+x) = 45
x being the first number, (3+2x) being the second, and (2+x) being the third.
not sure if i was supposed to try to simplify. hope this helps!!
