Answer:
23
Step-by-step explanation:
Area = π·r2 = 3.14·2.712 = 23 square kilometers(*)
Answer:
The slope is 9.
Step-by-step explanation:
Slope intercept form is y = mx + b
y = how far up
x = how far along
m = slope
b = value of y when x = 0
y = 9x - 2
The m is replaced by 9 which is the slope.
Answer:
c = 8.7 inches
Step-by-step explanation:
a^2 + b^2 = c^2
Substitute in the known values for a and b (the order doesn't matter):
(4.8)^2 + (7.3)^2 = c^2
multiply 4.8 times itself, 7.3 times itself:
23.04 + 53.29 = c^2
76.33 = c^2
Now find the square root of both sides of the equation (square root of c^2 = c):
8.736= c
It says round to the nearest tenth, so c = 8.7 inches

Answer:
n = m r - r t
Step-by-step explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t
