Hello!

An irrational number cannot be written as a fraction. Let's look at our options.

In D, the exponent and square root cancel each other out. This leaves us with ten, which is a rational and whole number.

For B, and repeating decimal can be written as a fraction using a specific formula. Therefore B is also rational.

For A, the square root of 196 is 14, which is a whole number and is therefore rational.

For C, the square root of 8 is 2.8284....... and continues on in no specified order. Therefore it cannot be converted into a fraction. Therefore, C)√8 is irrational.

I hope this helps!

How many extraneous solutions does the equation below have?
FrozenT [24]

<u>Answer</u>

0


<u>Explanation</u>

(2m)/(2m+3)-(2m)/(2m-3)=1

Simplifying the left hand first

(2m)/(2m+3)-(2m)/(2m-3) = {2m(2m-3) - 2m(2m+3)}/(4m²-9)

                                        (4m²-6m-4m²-6m)/(4m²-9)

                                         = (-12m) / (4m²-9)

Now this equet to 1

(-12m) / (4m²-9) = 1

-12m =  4m²-9

4m²+ 12m -9 =0 ⇒⇒⇒ This is a quadratic equation that has 2 real solutions.

4m²+ 12m -9 =0

m² + 3m + (3/2)²= 9/4 + 9/4

(m + 3/2)² = 18/4

m = √18/2 - 3/2                or m = -√18/2 - 3/2

    = 0.621                                       = -3.621

So we can say that the equation has NO extraneous solutions.

Show your work. What is 93 divided by 3 using repeated subtraction.
tamaranim1 [39]
To use repeated subtraction, you could keep subtracting 3 until you reach 0.
So, we can do
93-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3=0
This has 31 -3s,
So 91/3 is 31.

During a school event, Noah is selling pizza at the food stand for $1.25 per slice.
Eddi Din [679]

Answer:

1. When he sold 20 slices of pizza at $1.25 each, he made $20

  When he sold 50 slices of pizza at $1.25 each, he made $62.5

2. 96 slices of pizza. You would get that by dividing 120 by 1.25, as he needs to make $120, and each slice costs $1.25

What is the dollar value of 7 nickels and 8 quarters
victus00 [196]

Answer:

$2.35

Step-by-step explanation:

Nickels are worth 5 cents each and quarters are worth 25 cents.

7 nickels = 7 * 5 cents = 35 cents

8 quarters = 8 * 25 cents = 200 cents

Total = 200 + 35 = 235 cents

There are 100 cents per dollar, so we can find the dollar value by:

235/100 = $2.35
