Which number is an irrational number

12345 [234]

Answer:

A choice.

Step-by-step explanation:

Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.

From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.

B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.

For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.

Gina measured the amount of water her friends drink each day in gallons. The line plot shows the measurements.

vova2212 [387]

Line plots are used to represent data using lines and dots

The difference between the greatest amount of water and the least is 1/2

From the line plot (see attachment), we have the following parameters:

$Least = 8\frac 28$

$Greatest = 8\frac 68$

<h3>Calculating the difference</h3>

The difference (d) is then calculated as:

$d =Greatest -Least$

So, we have:

$d =8\frac 68 -8\frac 28$

Subtract the common terms (8)

$d =\frac 68 -\frac 28$

Take LCM

$d =\frac {6-2}8$

$d =\frac {4}8$

Reduce the fraction

$d =\frac {1}2$

Hence, the difference between the greatest amount of water and the least is 1/2

kenny6666 [7]

Answer:

The Federal taxes of total budget is 30%

C is correct.

Step-by-step explanation:

The chart below summarizes Ralph's annual expenses for the upcoming year.

We need to find the percentage for federal taxes.

First we find total annual budget from chart. We will add all the taxes.

Total annual budget = Federal taxes + State tax + Housing + Food + Medical +

Transportation + Recreation

Total Annual Budget = 18380 + 3448 + 15000 + 4880 + 6652 + 4332 + 3500 +

3260 + 1750

= 61202

Total Annual Budget = $61,202

Federal Taxes = $18,380

Now, we will find the percentage of federal taxes.

% of federal taxes $=\dfrac{18380}{61202}\times 100$

$=30.03\approx 30\%$

Hence, The Federal taxes of total budget is 30%
