What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?

Semmy [17]

Answer:

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

$\frac{3}{10}+\frac{1}{5} = ?$

To make adding our two fractions easier, we need to make sure they have like denominators.

$\frac{1*2}{5*2} =\frac{2}{10}$

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

$\frac{3}{10} +\frac{2}{10}=\frac{5}{10}$

$\frac{5}{10} =\frac{1}{2}$ or $0.50$

The farmer brought 80 acorn squash to the market.

shepuryov [24]

The total number of acorn squash that the farmer brought to the market = 80
Percentage of acorn squash was less when the day ended = 35%
Then
The amount by which the
number of acorn squash decreased at the end of the day = (35/100) * 80
   = 280/10
   = 28
Then
The number of acorn squash left with the farmer = 80 - 28
   = 52
So from the above deduction, we can easily conclude that the farmer was left with 52 acorn squash at the end of the day.

0.5 is a rational number.<br> True<br> False

velikii [3]

Answer:

true

Step-by-step explanation:

Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .

Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)

Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .

Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.

So in this case, yes, 0.5 is a rational number.
