Use long division to determine the decimal equivalent of fraction with numerator 2 and denominator 3. 0 point 6 bar 0 point 7 ba

VikaD [51]

Answer:

The correct answer is A

$0.\bar6$

Step-by-step explanation:

We want to determine the decimal equivalence of $\frac{2}{3}$ .

We perform the long division as shown in the attachment.

Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is $2$ , will be inside the long division sign.

We see that the quotient of our long division is $0.6666...$ .

We can rewrite this as $0.\bar6$

Therefore $\frac{2}{3}=0.\bar6$ .

Ada is making fresh orange juice for her family. She discovers that for every 3 oranges she squeezes, she gets 5 ounces of juice

ycow [4]

The ratios that have the same constant of proportionality as Ada's observation 15/9, 30/18

According to the question:

We are required to select all the ratios that have the same constant of proportionality as Ada's observation.

let y and x represent amount of juice and oranges respectively;

y = juices squeezed out

x = Oranges squeezed in

y = k × x

5 = k × 3

5 = 3k

k = 5/3

The ratios equivalent to the constant of proportionality is 15/9, 30/18

Write an equation in which the quadratic expression 4x^2-26x+42 equals 0. Must show all work to receive credit.

Masteriza [31]

Answer:

(a) (x + 3)(2x + 7) = 0

(b) These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.

Step-by-step explanation:

(a) We set 4x² -26x + 42 equal to 0:

4x² -26x + 42 = 0

Let's divide both sides by 2 to simplify this a bit:

2x² - 13x + 21 = 0

Now, we need factors a and b of 2 and c and d of 21 such that ac + bd = -13. The factors of 2 are: 1 and 2, so let's say a = 1 and b = 2. The factors of 21 are: (1, 21), (3, 7), (-1, -21), and (-3, -7). We see that if c = -7 and d = -3, this works:

ac + bd = 1 * (-7) + 2 * (-3) = -7 - 6 = -13

So, the factored form is:

(x - (-3))(2x - (-7)) = 0

(x + 3)(2x + 7) = 0

(b) So now we need to solve this. Set each of the two parenthetical expressions equal to 0:

x + 3 = 0

x = -3

AND

2x + 7 = 0

x = -7/2

These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.
