0.02
0.03
0.04
0.045
0.05
0.055

0.099991
0.099992
0.0999999999999999999999999

.
etc.

If you just want the number that's exactly in the middle
between 0.01 and 0.1 , then that's called the "average"
of 0.01 and 0.1 .

To find the average of any list of items ...
-- add them all up
-- divide their sum by the number of items on the list.

Your list has only two items on it.

-- Add them up . . . . . (0.01 + 0.1) = 0.11

-- Divide the sum by
the number of items on the list: 0.11 / 2 = 0.055 .

any number like 0.01 0.02 0.03 and so on to 0.09

1/3x+y=4
explain your answer Please!

Answers

Answer:

$y=-(1)/(3) x+ 4$

Step-by-step explanation:

You just have to subtract 1/3x on both sides of the equation to cancel the 1/3x on the left.

Combine 1/3 and x

Subtract y from both sides x/3 =4-y

Multiple both sides by 3 3• x/3 =3•(4-y)

Simplify both sides
X=12-3y

Reorder
X=-3y+12

One rate of an equivalent ratio is 9/n. Select two other rates, one that can be solved using equivalent fractions, and the other that can be solved with unit rates

Answers

The values given is not sufficient.
However, the rates could 18/2n or 90/10n

In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.

Rename each decimal as a percent: 0.03
0.3
0.045 and
0.49
Would really appreciate the help!

Answers

percent means out of 100 so 1%=0.01

so we multiply each decimal with 100 and get the decimal

0.03 times 100=3%
0.3 times 100=30%
0.045 times 100=4.5%
0.49 times 100=49%
