Answer:
720 mi²
Step-by-step explanation:
The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:
Area of a rectangle:
Replace the known values:
The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:
And last but not least, don't forget to put the unit!

Answer:
y = 0
Step-by-step explanation:
We assume you want to find y such that ...
- y = 3x +6
- 2x +4y = -4
Dividing the second equation by 2, we can write an expression for x.
x +2y = -2
x = -2y -2
Substituting this into the first equation gives ...
y = 3(-2y -2) +6
y = -6y -6 +6 . . . eliminate parentheses
7y = 0 . . . . . . . . . add 6y
y = 0 . . . . . . . . . . divide by 7
The value of y in the system of equations is 0.
The interest rate would be 20%.

We want to isolate r in this equation to rewrite the formula. The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have
We want to cancel the exponent, t, next. We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent. We will raise both sides of this to the 1/t power:
Now we cancel the 1 by subtracting, giving us
Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:
