Answer: 3/18 simplified 1/6
Step-by-step explanation:
6+5+7= whole (18)
1+2=part (3)
You would have to put 4.99 times 20 which will cost 99.80 for 20 gallons.
5.702 rounded to the nearest unit is 6. Look one decimal place further to determine what to round to. Greater than or equal to 5, round up. Less than 5, keep it the same.
For example, 5.402 rounded to the nearest unit would be 5 because the next decimal point is 4
For exponential functions
y=ab^x,
where
a is the scale vertical stretch factor,
b is the base, and
x the exponent (also independent variable)
It is a know fact that if the scale factor (1/2 or 2 in the answer choices) is positive, the graph is increasing if the base (3 or 1/3) is greater than 1.
This means that the base cannot be equal to 1/3. This eliminates choices 3 and 4.
Next, for a base greater than 1 (3>1), and the scale factor positive, it is a dilation (image gets bigger) if the scale factor is greater than 1. This eliminates the first choice where a=2.
This leaves us with the second choice where a=1/2, b=3, which is a shrink of the given exponential base function.
(3/4)/3
3/12
1/4
So he spent a 1/4 hour milking each group.
