Answer:
The number of trees at the begging of the 4-year period was 2560.
Step-by-step explanation:
Let’s say that x is number of trees at the begging of the first year, we know that for four years the number of trees were incised by 1/4 of the number of trees of the preceding year, so at the end of the first year the number of trees was
, and for the next three years we have that
Start End
Second year 
-------------- 
Third year 
-------------
Fourth year 
--------------
So the formula to calculate the number of trees in the fourth year is
we know that all of the trees thrived and there were 6250 at the end of 4 year period, then
⇒
Therefore the number of trees at the begging of the 4-year period was 2560.
Answer:
B
Step-by-step explanation:
sorry if its wrong
Step-by-step explanation:
Radius (r) = 2 ft
V = 4/3 × 22/7 × (2)³
= 4/3 × 22/7 × 8
= 33.52 ft³
Answer:
It will be 120°
It because if you matched those two points you will have two angles of 90° degree inside that square and in the triangle at the above 120-90= 30 degrees for both angles and since that all angles of the triangle are equal 180 then 180-(30+30)=120°.
Sorry if my explanation isn't that good.
Answer:
Step-by-step explanation:
- Start with y: y
- Start with y, divide by 7: (y/7)
- Start with y, divide by 7, then subtract 2: (y/7) - 2
