per pair of socks.
PLEASE QUICK QUICK

Answers

Answer:

The unit price is 7.79

Step-by-step explanation:

To find the unit price, you should divide what the money is by how many pairs the package has. So for this problem it would mean the equation would be 23.27/3 and the answer is 7.79.

Answers

Answer:

2/7

Step-by-step explanation:

So we multiply 3 by 2, and get 6.

Then we multiply 1 by 4, and get 4.

Next we give both terms new denominators -- 4 × 2 = 8.

So now our fractions look like this:

6/8 - 4/8

6 − 4 = 2

So the answer is:

2/8

Answers

For 1) Use the pythagorean theorem and the formula for it is a^2+b^2=c2
so that will be 3^2+3^2=c^2
9+9=c^2
18=c2
then
$√(18) which is √(9(2)) √(9) √(2) the finally 3 √(2) ---- is the unsimplified formsimplified form is$ ≈4.2426
and the nearest hundredth 4.24

The correct answers are:

#1: A) c = √18

B) c = 3√2

C) c = 4.24

#2: A) 4/13 > 3/10

B) 79/260

#3: 4.36

Explanation:

#1: A) We use the Pythagorean Theorem to solve this:

a² + b² = c²

3² + 3² = c²

9 + 9 = c²

18 = c²

Taking the square root of each side:

√18 = √c²

√18 = c

B) To simplify √18, we first find the prime factorization of 18:

18 = 9*2

9 = 3*3

This gives us

18 = 3*3*2

When we take the square root, we are looking for pairs. We have a pair of 3's; this means we take a 3 out:

3√2

C) In the calculator, we see that 3√2 = 4.24.

#2: A) First, we find a common denominator. The first thing that both 13 and 10 will divide into is 130:

(4*10)/130; (3*13)/130

40/130; 39/130

Since 40 > 39, this means that 4/13 > 3/10.

B) There is not enough space between the two fractions to use 130 as the denominator; we will double that to 260:

(40*2)/260; (39*2)/260

80/260; 78/260

The fraction between these two would be 79/260.

#3: Using the Babylonian method, we first make a guess. Since 9 is nearly half of 19, we will start there.

Next, we divide 19 by our guess:

19/9 = 2.111

We average this quotient with our guess:

(9 + 2.111)/2 = 11.111/2 = 5.5555

This is our new guess. Now divide 19 by this guess:

19/5.5555 = 3.4200342

Average this with our guess:

(5.5555+3.4200342)/2 = 4.4877671

This is our new guess. Divide 19 by this guess:

19/4.4877671 = 4.233731291

Average this with our new guess:

(4.4877671+4.233731291)/2 = 4.360749196

This is our new guess. Divide 19 by this guess:

19/4.360749196 = 4.357049476

Average this with our new guess:

(4.360749196+4.357049476)/2 = 4.358899

Make this our new guess. Divide 19 by this guess:

19/4.358899 = 4.3588988

Average this with our guess:

(4.358899+4.3588988)/2 = 4.3588989

Since the hundredths place has been the same the last few lines, we round to that: 4.36.

Decrease from 126 ounces to 48 ounces percent

Answers

Answer: There is 61.9% decrease in the value from 126 ounces to 48 ounces.

Step-by-step explanation:

Original value=126 ounces

New value = 48 ounces

Difference = 126-48 = 78 ounces

So, Percentage of decrease value is given by

$(Difference)/(Original)* 100\n\n=(78)/(126)* 100\n\n=61.9\%$

So , there is 61.9% decrease in the value from 126 ounces to 48 ounces.

Answer:

Decrease in percentage = 61.9%

Step-by-step explanation:

Decrease from 126 ounces to 48 ounces percent

First find out the amount of decrease. Subtract the number to find the amount of decrease

$126-48=78$

now find out which percentage is 78

percentage = $(78)/(126) \cdot 100=61.9$

Decrease in percentage = 61.9%

Which of the statements below best describes why the graph relating the total amount of gasoline in the tank, y, to the number of gallons that she added to it, x, will be continuous or discrete? A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount. B. The graph will be continuous because we are not told a maximum value for the amount of gas. C. The graph will be discrete because there are already exactly 4 gallons of gas in the tank.
