Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>

Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
Answer:
825/3 = 275 which is how many miles she drove in January.

46 cm
Step-by-step explanation:
If Susan can knit 1 cm per night and knits for 10 nights the is 10cm. Then you add the 10cm to the 36cm to get 46cm.
Let x = number of months.
Let y = total number of fish in pond.
6% of 3,000 = 180 fish
We can use an equation to help us with this problem.
y = 3,000 + 180x - 400x. Combine like terms.
y = 3,000 - 220x. Plug 9 in for x.
y = 3,000 - 220(9). Solve for y
y = 1,020.
There are 1,020 fish in the pond after 9 months.
7/10-3/10=2/5
3/10+1/10=2/5
