Use the number line to determine whether the two fractions 1/2, 4/8 are equivalent. Yes or no.

You could do that (yes), but in many cases, you would need to determine equivalence some other way (no) before plotting the numbers on a number line.

If the number line is graduated in a manner that makes 1/2 clear, and also makes 4/8 clear, then it is possible to determine that both values lie at the same point. If the number line is graduated in tenths or hundredths (for example), you would need to convert both numbers to that format before plotting.

Which ordered pair is the vertex of y=|x+5|-1
nataly862011 [7]

We can tell that this absolute value function opens up, so the vertex will be at the x value where the output is the lowest. The lowest you can make |x+5| go is 0, because everything else will be a positive number is greater. The one x value that does that is -5. Plug in -5, and you will get |-5+5|-1=-1. So, the ordered pair for the vertex will be (-5,-1)

A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles. What is the probability of selecting a red marble, replacing
RUDIKE [14]

Answer:

3/20

Step-by-step explanation:

The total number of marbles is

3 red marbles+ 2 blue marbles+ 5 green marbles = 10 marbles

P(1st marble is red) = red marbles/total

                                =3/10

We replace the marble so there are still 10 marbles in the bag

P(2nd marble is green) = green marbles/total

                                =5/10 = 1/2

P(1st red, 2nd green) = P(1st marble is red) * P(2nd marble is green)

                                   =3/10 *1/2

                                    =3/20

Tina lives in a state that charges her 4.5% state income tax on her federal taxable income. If her federal taxable income is $61
Irina-Kira [14]

$ 2772 is paid in state income tax

<em><u>Solution:</u></em>

Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income

Federal taxable income = $61,600

<em><u>To find: Amount paid by Tina in state income tax</u></em>

Tax rate = 4.5 %

<em><u>Which means, 4.5 % of $61,600 is paid as tax</u></em>

Tax\ Rate = 4.5 \% \text{ of } 61600

Here, "of" means multiplication or product

Tax\ Rate = 4.5 \% \times 61600\\\\Tax\ Rate = \frac{4.5}{100} \times 61600\\\\Tax\ Rate = 0.045 \times 61600\\\\Tax\ Rate = 2772

Thus $ 2772 is paid in state income tax
