How do you add and subtract radicals? If you could please give me the instructions step by step and with examples, that would be

helpful too.
It is for a homework assignment in school, but I wasn't there the day they did it.
p.s I need an explanation right away.

You can add and subtract radicals by ensuring that they have same radical parts.

<h3>What's radical?</h3>

It should be noted that a radical expression is an expression that contains the radical symbol which is ✓.

The necessary steps to add or subtract radicals include:

Identify the radical parts.

Add them together.

If there's unlike radical parts, one will manipulate the parts involved before solving.

Example: Add ✓63 + 5✓7

It should be noted that ✓63 = ✓9 × ✓7 = 3✓7

Therefore, ✓63 + 5✓7 will be:

= 3✓7 + 5✓7

= 8✓7.

a large water bottle holds 32 fluid ounces which is 0.946353 liter. round this decimal to the nearest thousandth. explain how yo
Aneli [31]

Answer:

0.946 liter

Step-by-step explanation:

Here, we are told to round 0.946353 to the nearest thousandth.

The nearest thousandth is simply the third value after the decimal point.

Now to successfully round this number, we need to consider the number after this number. If the number is less than 5, then we round it up as zero and add to the thousandth digit.

in the case where the fourth number is higher than or equal to 5, we turn it to 1 and add it to the thousandth number

In the case of this question however, we can see that the number is less than 5, so we can only round to 0 and this does not affect the thousandth digit .

What is the measure (in radians) of central angle theta in the circle below? enter an exact expression.
Llana [10]

Answer:

Measure of central angle is 3.665 radians

Step-by-step explanation:

In this question, we are trying to get the value of the central angle.

As we can see, the radius of the circle is 12cm while the length of the major arc is 14 pi cm.

Mathematically the length of an arc is calculated as follows;

Length of arc = theta/360 * 2 * pi * r

Plugging the values we have from the question;

14 pi = theta/360 * 2 * pi * 12

divide both sides by 2pi

7 = theta/360 * 12

360 * 7 = 12 theta

theta = (360 * 7)/12

theta = 210

Since 1 degree = pi/180 radian

it means 210 degrees = 210 * pi/180 = 3.665 radians

It’s linear so you map out the first differences and then put it into y=Mx+b form. For the you gotta find the y intercept
Alika [10]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

Let's find the slope (m) :

  • \dfrac{y2 - y1}{x2 - x1}

  • \dfrac{16 - 11}{9 - 6}

  • \dfrac{5}{3}

slope of given line is 5/3

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :

  • y = mx + c

  • 11 =   \bigg(\dfrac{5}{ 3}  \times 6 \bigg)  + c

  • 11 = (5 \times 2) + c

  • 11 = 10 + c

  • c = 11 - 10

  • c = 1

value of y - intercept (c) = 1, so our equation will be :

  • y = mx + c

  • y =  \dfrac{5}{3}x  + 1

Find the slope of the line containing the points in the table below
zhannawk [14.2K]

Answer:

slope = 3

Step-by-step explanation:

Choose any two points: For example, (2, 4) and (4, 10)

Find the difference in y. This is called the "rise."

rise = 10 - 4 = 6

In the same order, find the difference in x. this is called the "run."

run = 4 - 2 = 2

slope = rise/run

slope = 6/2

slope = 3

skelet666 [1.2K]
<span>Christa went shopping for back to school clothes.
She paid a total of 176 dollars before the tax was added on.
Now, how much will she be paying if the sales tax is 6% what was the total amount she paid.
Solutions:
=> 176 dollars * 6% to get the amount
=> 6% / 100% = 0.06
=> 176 dollars * .06 = 10.56
Now, let’s add to get the answer
=> 176 dollars + 10.56 dollars = 186.56 dollars</span>
