The answer would be 483,972 miles = 55
Answer:
39
Step-by-step explanation:
(16-2w)^2 + (3y÷3z)
Let w=5 y=9 and z=3
(16-2*5)^2 + (3*9÷3*3)
PEMDAS says parentheses first
Multiply and divide in the parentheses
(16-10)^2 + (27÷9)
Then add and subtract in the parentheses
(6)^2 + (3)
Now the exponent
36 +3
39
Answer:
Step-by-step explanation:
We can treat this as a units conversion problem. Each multiplier is a fraction that has the same value in the numerator as the denominator, but expresses that value with different units. We choose to cancel units we don't want, and replace them with units we do want. Ultimately, we're evaluating the expression ...
time = quantity/rate
(4 mi²) × (640 ac/mi²) × (5 min)/(2.5 ac) × (1 h)/(60 min)
= (4·640·5)/(2.5·60) h = 85 1/3 h
It will take about 85 hours to plant the farm.
__
At 8 hours per day, that is (85 1/3)/(8) = 10 2/3 days.
It will take about 11 days to plant the farm.
Step-by-step explanation:
Midpoint = 1/2(6+9,8+7)
= 1/2(15,15) = (15/2,15/2)
