A Farmer Watered 3/8 of a field, What Percentage to the Fraction of the field the farmer watered?

Answers & Step-by-step explanation:

A square root is a number that when multiplied by itself, equals the number you were asked to square root. For example, 2 is the square root of 4, because 2 x 2 = 4.

There is a method in algebra to simplify square roots into smaller square roots, where one can be solved. To do this, we need to find a perfect square that can be multiplied with the other square root to equal the number you were asked to square root.

Now, let's solve your problems!

___________________________________________________________

[tex]\sqrt{56}[/tex] = [tex]\sqrt{2^{2} * 14[/tex]

Now, we pull out the [tex]2^{2}[/tex] from under the radical, since we can square root this. [tex]\sqrt{2^{2} }[/tex] is simply 2.

[tex]2\sqrt{14}[/tex]

Since we can't solve [tex]\sqrt{14}[/tex], this is the final answer that your assignment is wanting.

___________________________________________________________

[tex]\sqrt{84}[/tex] = [tex]\sqrt{2^{2} * 21[/tex]

Now, we pull out the [tex]2^{2}[/tex] from under the radical, since we can square root this. [tex]\sqrt{2^{2} }[/tex] is simply 2.

[tex]2\sqrt{21}[/tex]

Since we can't solve [tex]\sqrt{21}[/tex], this is the final answer.

___________________________________________________________

[tex]\sqrt{-9}[/tex] = [tex]\sqrt{-1 * 9}[/tex]

Now, since this the number is negative, we must separate the negative out. so [tex]\sqrt{-9}[/tex] becomes [tex]\sqrt{-1 * 9}[/tex]. Since the square root of 9 is 3, we can rewrite this as:

[tex]3\sqrt{-1}[/tex]

However, since [tex]\sqrt{-1}[/tex] is imaginary, we must replace it with i. This also allows us to get rid of the square roots.

The answer becomes:

3i

___________________________________________________________

[tex]3\sqrt{18}[/tex]

This one is already partly simplified. Notice how the 3 is not under the radical. The only thing we have to work with is the [tex]\sqrt{18}[/tex].

[tex]\sqrt{18}[/tex] = [tex]\sqrt{9 * 2}[/tex]

We can square root 9 to get 3.

[tex]3\sqrt{2}[/tex]

Now, we multiply back the 3 from earlier to get:

[tex]9\sqrt{2}[/tex]

___________________________________________________________

[tex]\sqrt{28a^{2}b^{3} }[/tex]

This one may look daunting because we have the variables, but we can break it down and solve it just as easily as the rest. The first step is to square root the a² term, the answer is a. We can rewrite this as:

[tex]a\sqrt{28b^{3} }[/tex]

Next, we need to simplify [tex]\sqrt{28}[/tex], just like we did with all the other problems.

[tex]\sqrt{28}[/tex] = [tex]\sqrt{4 * 7}[/tex]

Since [tex]\sqrt{4}[/tex] is 2, we can move it out of the radical.

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

Since we can do anything with the [tex]b^{3}[/tex] term, that stays under the radical.

The answer is:

[tex]2a\sqrt{7b^{3} }[/tex]

Answer:

[See Below]

Step-by-step explanation:

C.

The solution to this is x ≤ 4.

So then we look at the graphs and choose the correct one.

When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.

Answer: Bentley have to pay  $20.5 in a month in which he downloaded 10 songs.

Bentley have to pay  $(13+0.75s) in a month in which he downloaded s songs.

Step-by-step explanation:

As per given,

Total amount need to pay = (Monthly cost) + (Number of songs downloads)  x (Charges for each song)

Here, Monthly cost = $13

Charges for each song = $0.75

If Number of songs downloads = 10

Then, Total amount need to pay = $ (13 +(10) (0.75))

= $( 13+7.5)

= $ 20.5

So, Bentley have to pay  $20.5 in a month in which he downloaded 10 songs.

If Number of songs downloads = s

Then, Total amount need to pay (in $) = 13 + (s)(0.75)

= 13+0.75s

So, Bentley have to pay  $(13+0.75s) in a month in which he downloaded s songs.

If Number of songs downloads = 10

$ 20.5

If Number of songs downloads = s

13+0.75s

brainliest or a thank you please :)) <33

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

In a square ABCD, if AB = (3x-8) and BC = (x+12), find the value of x. Also, find the length of each side of the square.

Note that all sides of a square are equal. Hence AB = BC for the square ABCD.

Given AB = (3x-8) and BC = (x+12), then AB = BC

3x-8 = x+12

collect like terms;

3x-x = 12+8

2x = 20

x = 20/2

x = 10

Substitute x = 10 into any of the side. Using side AB

AB = 3x-8

AB = 3(10)-8

AB = 30-8

AB = 22

BC = x+12

BC = 10+12

BC = 22

Hence x = 10 and the length of each side is 22

Answer:

AC =5

BC =  12

AB = 13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

(n-1)^2 + (2n)^2 = (n+7)^2

FOILing

n^2-2n+1  + 4n^2 = n^2+14n+49

Combine like terms

5n^2-2n+1   = n^2+14n+49

Bring everything to the left

5n^2-2n+1 -n^2-14n-49  = n^2+14n+49-n^2-14n-49

4n^2 -16n -48 = 0

Divide by 4

n^2 -4n -12 = 0

Factor

( n-6)(n+2) =0

Using the zero product property

n-6 =0  n+2 =0

n=6    n=-2

Since the length cannot be negative

n=6

AC = n-1 = 6-1 =5

BC = 2n = 2*6 = 12

AB = n+7 = 6+7 = 13

Given :

Hypotenuse of right angle triangle = n + 7

Base = n - 1

Altitude = 2n

Using Pythagoras theorem :

→ ( n + 7 )² = (n - 1)² + (2n)²

→ n² + 14n + 49 = n² - 2n + 1 + 4n²

→ n² + 14n + 49 = 5n² - 2n + 1 = 0

→ n² + 14n + 49 - 5n² + 2n - 1 = 0

→ -4n² + 16n + 48 = 0

→ -4(n² - 4n - 12) = 0

→ n² - 6n + 2n - 12 = 0

→ n(n - 6) + 2(n - 6) = 0

→ (n - 6)(n + 2) = 0

As n ≠ Negative

So, n ≠ -2

So, n = 6

Hypotenuse = n + 7 = 6 + 7 = 13

Base = n - 1 = 6 - 1 = 5

Altitude = 2n = 2 × 6 = 12

So,

AB = 13

AC = 5

BC = 12

Step-by-step explanation:

===============================================

Let a,b,c,d be scalars.

In general if v and w are two vectors such that

v = <a, b>

w = <c,d>

then the difference of the two vectors is

v - w = <a-c, b-d>

so we subtract the coordinates

-----------------

Using that idea for the given vectors leads to

v = <9, -1>

w = <-1, -6>

v - w = <9 - (-1), -1-(-6)>

v - w = <9+1, -1+6>

v - w = < 10, 5 >

Answer:

x + 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of rectangle = 3x + 6

Width of rectangle = 4x – 1

Width of door =..?

A careful observation of the diagram shows that the door is located along the length of rectangular room.

In a rectangle, two sides are equal. Therefore,

x + door + x = 3x + 6

Making door subject of the above formula, we have:

x + door + x = 3x + 6

door + x + x = 3x + 6

door + 2x = 3x + 6

Subtract 2x from both side

door + 2x – 2x = 3x + 6 – 2x

door = 3x – 2x + 6

door = x + 6

Therefore, the width of the door is x + 6

and independent variable It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. and a Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

Answer:

Real numbers are mainly classified into rational and irrational numbers. Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.

There are 4 types of real numbers.

Rational Numbers

Irrational Number

Natural Numbers

Whole Numbers

Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers.

The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers.

Rational Numbers; Any number specified in the form of a p/q or ratio fraction is called a rational number. The numerator is defined as p, and the denominator is represented as q, where q is not equal to zero. A rational number may be an integer, whole, and natural number.

For example: 0.67, 17, 214, etc.

Irrational Number; Irrational numbers are defined as the real number that cannot be represented as a simple fraction. In other words, it cannot be represented as a ratio, such as p/q, where p and q are integers, q≠0. It is the opposite of rational numbers.

For example; √5, √11, √21, etc.

Natural Numbers; An integer greater than 0 is a natural number. Natural numbers start at 1 and move to infinity.

For example; 1, 2, 3, 4, 5.

Whole Numbers; The whole number is the number system that contains all positive integers from 0 to infinity. The whole number is an integer of 0 or greater numbers.

For example: 1, 2, 3, 4, 5…..
