Answer:
67 million square miles
Step-by-step explanation:
The area of a sphere is given by ...
A = 4πr²
So the area of the Earth is approximately ...
A = 4π(4000 mi)² ≈ 2.01×10^8 mi²
The area of the 1/3 that is not covered by water is approximately ...
(2.01×10^2 mi²)/3 = 6.7×10^7 mi²
The land area is estimated to be about 67 million square miles.
Answer:
x = 
Step-by-step explanation:
Given
Ax + By = C ( isolate the term in x by subtracting By from both sides )
Ax = C - By ( divide both sides by A )
x =
Substitute the values of the size of the 5 batches to the
model.
For example
@x = 20
f(20) = 2*20 – 23 = 17
f(25) = 2*25 – 23 = 27
f(26) =29
f(27) = 31
f(34) = 45
Therefore the answer is the first choice (17, 27, 29, 31,
42)
Answer:
x = 0
Step-by-step explanation:
3(x - 2) + 15= -3(x - 3)
3x - 6 + 15 = -3x + 9
3x + 9 = -3x + 9
3x + 3x = 9 - 9
6x = 0
x = 0
