Step-by-step explanation:

Distance formula:

[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]

Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Ricky charges $112.50 for a 3-hour job.

Now,

Since, Ricky charges for 3 hour job = $112.50

Hence, The charges for 1 hour job = $112.50 / 3

                                                     = $37.5

So, The charges for 5 hour job = 5 x $37.5

                                                = $187.5

Thus, The charge for a 5-hour job will be $187.5.

Step-by-step explanation:

Multiply 10 by 4 which 4 represents the starting Iphone memory storage and then 10 represents the value of memory for the 10th model.

By solving the exponent, we find that the 10th version will have 2048 gigabytes of memory.

An exponent is a number that is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.

Answer:

She needs $175.

Step-by-step explanation:

3.50 X 6= $21. (196-21=175)

So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.

Let's say Olive oil = O, Balsamic Vinegar = B, Salad Dressing = S

For the salad dressing she uses 3 parts olive oil to 2 parts balsamic vinegar

So we can say for every 3 ml of olive oil, she needs 2ml of balsamic vinegar

We know she has 120ml of olive oil, so first step is to find how much balsamic vinegar she will be using.

Remember, for every 3 ml of Olive Oil, she needs 2ml of Balsamic Vinegar .

if you do 120 divided by 3 = 40

So she is making 40 times the amount of salad dressing.

This means you need to multiply the  amount of balsamic vinegar by 40.

B = 40 times 2 = 80 ml

So now for the dressing we know :

She uses 120 ml of olive oil and 80 ml of balsamic vinegar.

So to find how many ml of salad dressing she can make, you just add the two.

S = O + B = 120 + 80 = 200 ml

Using proportions, it is found that she can make 80 milliliters of salad dressing.

The rule of three is:

3 parts of olive oil - 2 parts of balsamic vinegar.

120 ml - x ml

Applying cross multiplication:

[tex]3x = 2(120)[/tex]

[tex]3x = 240[/tex]

[tex]x = \frac{240}{3}[/tex]

[tex]x = 80[/tex]

She can make 80 milliliters of salad dressing.

Answer:

  B) x scale of -15 to 15

  C) y scale of 0 to 15

Step-by-step explanation:

The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)

An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...

  -15 ≤ x ≤ 15 . . . . choice B

 0 ≤ y ≤ 15 . . . . . . choice C

Determine the value of T

[tex]\frac{1}{2}(4.5 + b_2) * 6 = 21[/tex]
