Answer: The independent variable is the brand and the dependant variable is the amount of water you use.

Step-by-step explanation:

The Independent variable is the condition that you change in an experiment.

The dependant variable is the condition that you measure in an experiment.

The independent variable in the student's experiment is the type of paper towel used.

In an experiment, there are three types of variables:

In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

Answer:

Step-by-step explanation:

We have:

[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]

And we want to find two different angles between 0 and 180 that satisfy this equation.

First, let's get our sine out of the denominator. Notice that this is the same as:

[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]

Cross-multiply:

[tex]2\sin(\theta)=\sqrt{3}[/tex]

Divide both sides by 2:

[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]

Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!

#2 is correct. However, double check #3. The answer's down there too... :)

[Blank space...]

[More blank space...]

[And more...]

Answer for 1)

We have:

[tex]\sin(\theta)=\sqrt{3}/2[/tex]

So, at what points between 0 and 180 does sine equal √3/2?

If we refer to the unit circle, we can see that this happens twice: at 60.

Thus, the second time it occurs will be at 180-60 or 120.

So:

[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]

Answer for 3)

So you are correct for the first three. So:

[tex]\sin(54)=t[/tex]

However, sine stays positive. So, our angle must be between 0 and 180.

So, instead of 180+54, it should be 180-54, giving us:

[tex]\sin(54)=\sin(126)=t[/tex]

Answer:

I Couldn't find a variable to solve for.  This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Step-by-step explanation:

Simplify

-4 + 2x = 5 + -1(x + -3) + 3x

Reorder your terms

-4 + 2x = 5 + -1(-3 + x) + 3x

-4 + 2x = 5 + (-3 * -1 + x * -1) + 3x

-4 + 2x = 5 + (3 + -1x) + 3x

Combine your like terms 5 + 3 = 8

-4 + 2x = 8 + -1x + 3x

Combineyour like terms -1x + 3x = 2x

-4 + 2x = 8 + 2x

Add -2x to each side of your equation.

-4 + 2x + -2x = 8 + 2x + -2x

Combine your like terms: 2x + -2x = 0

-4 + 0 = 8 + 2x + -2x

-4 = 8 + 2x + -2x

Combine your like terms: 2x + -2x = 0

-4 = 8 + 0

-4 = 8

Solving

-4 = 8

I'm sorry but I Couldn't find a variable to solve for.  This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer:

Step-by-step explanation:

Since we are to construct the fence around the park, to determine the length of the fence, we will find the perimeter of the rectangular car park.

Perimeter of the car park = 2(Length  + Width)

Given

Width of car park = 12m

Length of the car park = 34 m

Substituting the given data into the formula;

Perimeter of the park = 2(12+34)

Perimeter of the park = 2(46)

Perimeter of the park = 92m

Hence the length of fence that should be ordered to guarantee that there will be enough to surround the car park is 92m

Answer:

la respuesta correcta es $35.15

Answer:13 miles over the speed limit

Step-by-step explanation:

Answer:

H

Step-by-step explanation:

The fine for speeding is $17 mile per hour. Thus, for speeding for a total of x miles per hour above the posted speed limit of 30 mile per hour, there will be a fine of: 17(x - 30)

X in the equation is the speed of the driver and the negative sign in the equation shows that the driver was traveling at a total speed greater than the posted speed limit (thus, x - 30 is the speed above the posted speed limit in which the driver will be fined for).

Since the driver was fined $221, the equation becomes:

17(x - 30) = 221

divide both sides by 17

x - 30 = 221/17

x - 30 = 13

x = 13 + 30

x = 43

The driver was fined for travelling at a speed of 43 miles per hour which is 13 greater than the posted speed limit.

Step-by-step explanation:

its c don't pick any other answers only c

According to the operation done by Sylvi, the correct expression is 4.75 × 3.25 = 15.4375. Hence, option (c) is correct.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the operation given in the question,

15.4375 ÷ 3.25 = 4.75

As per the rules, if a number is in the division on the left-hand side, after going to the right-hand side it will become in the form of multiplication with another number.

Then,

4.75 × 3.25 = 15.4375.

Answer:

For the first three situations, the sum is zero.

Step-by-step explanation:

As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.

Shawna spends $20 and she earns $20,

So, the sum of the total amount is

-20+20=0

A diver dove down 20.14 feet under-water and then descended 20.14 feet.

First, the diver ascends 20.14 feet then descends the same.

As the ascending and the descending are opposite to each other.

The sum of both is

+20.14-20.14=0

So, in this case, the diver has a sum of zero.

For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,

So, the total points are

+2-2=0

So, in this case, the golfer has a sum of zero points.

In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.

This time, there is an addition of $5.50 to the money you already have.

So, the total money, after receiving the $5.50 is

$5.50+$5.50=$11

In this case, the sum of the total amount is not zero.

Hence, for the first three situations, the sum is zero.

Answer:

Yes they are parallel

Step-by-step explanation:

They have the same slope.

x= 1 + 5 √2

x= 1 - 5 √2

The values of x in the expression are x = 1 + √51 and x = 1 – √51.

We have,

Expanding the left side of the equation, we get:

(x – 1)2 = x2 – 2x + 1

So, we have:

x2 – 2x + 1 = 50

Subtracting 50 from both sides, we get:

x2 – 2x – 49 = 0

Now, we can use the quadratic formula to solve for x:

x = [2 ± √(22 – 4(1)(–49))] / (2)

x = [2 ± √(204)] / (2)

x = [2 ± 2√51] / (2)

x = 1 ± √51

Therefore,

The values of x are x = 1 + √51 and x = 1 – √51.
