A cell is placed in a 15% solute solution and the cell shrinks. What is the tonicity of the 15% solution solution

Answer:

Step-by-step explanation:

x = 4y - 3

2x +3y = 16

First, plug the equation x = 4y - 3 into the second equation so it looks like this:

2 (4y - 3) + 3y = 16    Now we only have one variable to solve for.

8y - 6 + 3y = 16    Simplify like variables

11y - 6 = 16     try to get y by itself

11y = 16 + 6

11y = 22     divide both sides by 11

y = 2

Now you can put Y back into the first equation

x = 4y - 3

x = 4(2) - 3

x = 8 - 3

x = 5

so the answer is x = 5 and y = 2

The distance between the two given points (5, 5) and (1 ,5) on a coordinate plane is equal to 4 units.

As given in the question,

Let the coordinates of the two given points in the coordinate plane are represented by:

 (x₁ , y₁) = (5, 5)

(x₂ , y₂ ) = (1 ,5)

Distance between two points  = √ ( x₂ - x₁)² + ( y₂ - y₁)²

Substitute the value we get,

Required Distance

= √ ( 1 - 5 )² + ( 5 - 5 )²

= √ ( -4 )² + ( 0 )²

= √ 16

= 4 units as distance is always positive.

Therefore, the distance between the given points on a coordinate plane is equal to 4 units.

The above question is incomplete , the complete question is :

According to the unitary method, the store that has the best deal is Store 1 and it cost $202.18

The term unitary method is known as a process of finding the value of a single unit, and based on this value.

Here we have the original prices of the rugs are as follows:

Store #1: $289

Store #2: $265

Store #3: $310

And the discount on each store is written as,

Store #1: 20% (decrease)

Store #2: 12%(decrease)

Store #3: 30%(increase)

And the tax details are given as,

Store #1: 8%

Store #2: 8%

Store #3: no tax.

Then the shipping and the handling charges is $5.9

Then the price for each of the store is calculated as,

=> Store 1 = 289 - [(289 x 0.20) + (289 x 0.08) + 5.9] = 202.18

=> Store 2 = 265 - [(265 x 0.12) + (265 x 0.08) + 5.9] = 206.1

=> Store 3 = 310 + (310 x 0.30) - 5.9 = 397.1

By rounding to the nearest tenth, we may determine the radius to be RG = 20.1 feet.

1.The circumferences of the two circles are 220 feet and 126 feet, respectively. We may think of a circle's circumference as a form of "perimeter."

2. The following is the radius of the circle made by Ana's brother in the blue car:

We know that the following formula determines a circle's circumference:

[tex]C=2\Pi \ r[/tex]

Then, we must get r by solving this equation. We know that C is 220 feet and pi is 3.14. Next, we have

[tex]220=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{220}{2 \pi} \\\Rightarrow r=\frac{220}{2 \cdot 3.14} \\\Rightarrow r=35.0318[/tex]

The radius, rounded to the closest tenth, is RB = 35.0 feet (or 35 feet).

3. Using the same method, we can determine the radius of the circle that Ana's sister drew in the green automobile (she travelled 126 feet).

[tex]126=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{126}{2 \cdot 3.14} \\\Rightarrow r=20.0637[/tex]

Answer:

The multiplicative inverse of -11/7 is "A. -7/11".

Step-by-step explanation:

The multiplicative inverse of a fraction is found by flipping the numerator and denominator. So, if a fraction a/b has a multiplicative inverse, then it must be true that:

a/b * (b/a) = 1

In this case, we want to find the multiplicative inverse of -11/7:

-11/7 * x = 1

So, we flip the numerator and denominator of -11/7 to find x:

x = -7/11

Therefore, the multiplicative inverse of -11/7 is -7/11, which is option A.

The 45 45 90 triangle theorem states that 45 45 90 special right triangles have sides of which the lengths are in a special ratio of 1 : 1 : 2 and two 45° angles and one right angle of 90°.

When two rays intersect and form a 90˚ angle or are perpendicular to each other at the intersection, they are said to form a right angle. It is the most frequently encountered angle in our daily lives. It can be noticed in room corners, box edges, mobile phone screens, and so on.

A square's and a rectangle's sides always make a right angle with each other. It is represented in radians as /2.

The angle formed by two lines that are perpendicular to each other is called a right angle. A right angle is equal to 90° and is in the shape of the letter "L". In the following figure, ray AB and BC form a right angle ABC.

The equation (x-6)²(x+2)² can be factored by using the difference of squares factorization. This factorization states that for any two binomials a-b and a+b, their product can be written as (a-b)(a+b)= a²-b². In this case, we have (x-6)² and (x+2)², which can be factored as (x-6)² = (x-6)(x-6) = (x-6)², and (x+2)² = (x+2)(x+2) = (x+2)².

So, the equation (x-6)²(x+2)² can be factorized as (x-6)²(x+2)² = (x-6)² * (x+2).

The roots of the equation are the values of x that make the equation equal to zero. To find the roots of the equation, we set each of the factors to zero and solve for x.

The entire area bounded by any triangle's three sides is referred to as the triangle's area.

In essence, it is equivalent to 1/2 of base times height, or A = 1/2 b times h. A triangular polygon's base (b) and height (h) must be known in order to calculate its area.

Whether a triangle is scalene, isosceles, or equilateral, it can be used to solve any kind of triangle.

Be aware that the triangle's base and height are at right angles to one another. In square units, the area unit is measured (m2, cm2).

Example :

Consider this triangle with a base of 3 cm and a height of 4 cm. What is its area?

Employing the formula,

Triangle's area is equal to half of b times h.

= 1/2 × 4 (cm) × 3 (cm) (cm)

= 2 (cm) × 3 (cm) (cm)

= 6 cm2.

In addition to the method mentioned above, Heron's formula can be used to determine a triangle's area when we know the lengths of its three sides.

In addition, when two sides of a triangle are known as well as the angle that forms between them, the area can be calculated using trigonometric functions. For each of these circumstances, we shall calculate the area.

The methods used in factoring are Greatest Common Factor (GCF), Grouping Method, Using Identities, Factor Theorem, and Polynomial with Four Terms.

Greatest Common Factor (GCF): To factorise, We have to find out the greatest common factor, of the given polynomial.

a(b + c) = ab + ac

But in the matter of factorisation, it is just an inverse process;

ab + ac = a(b + c)

where p is the greatest common factor.

Grouping Method: This method is also stated to be factoring by pairs. In this method, the given polynomial is distributed in pairs to find the zeros. 

Factoring Using Identities: The factorisation can be accomplished also by using algebraic identities. The most typical identities used in terms of the factorisation are:

(α + β)² = α² + 2αβ + β²

(α – β)² = α² – 2αβ + β²

α² – β² = (α + β)(α – β)

Factor Theorem: For a polynomial g(x) of a degree greater than or equal to 1,

x - b is a factor of g(x), if g(b) = 0

If g(b) = 0, then x - b is a factor of g(x)

Where ‘b’ is a real number.

Factoring Polynomial with Four Terms:

For example, x³ + x² – x – 1 is the polynomial. 

Split the given polynomial into two parts.

(x³ + x²) + ( –x – 1)

We can see, from the first part, x² is the greatest common factor and from the second part, we can take out the minus sign. Thus,

x²(x + 1) - 1(x + 1)

Again, regrouping the terms as the factors.

(x² - 1) (x + 1)Therefore, the factorisation of x³+ x² – x – 1 gives (x² -1) (x+1).

What exactly is a math graph?

The term "graph" has at least two separate meanings in mathematics. The word "graph" in elementary mathematics refers to a plot or a function graph. In mathematical terms, a graph is a collection of points and the relationships between a subset of those points (which may be empty).

To graph this solution set, we use a number line, and place an open dot at 5 to indicate that 5 is not included in the solution set. Then, we shade the portion of the number line to the left of 5, which represents all the values of g that are less than 5. The graph of the solution set would look like this:

An absolute value equation is an equation that contains an absolute value expression. To solve an absolute value equation, you need to consider two cases: when the argument inside the absolute value is positive and when it is negative.

Here is an example of how to solve an absolute value equation:

|x - 3| = 5

To solve this equation, we need to consider two cases: x - 3 = 5 and x - 3 = -5.

Case 1: x - 3 = 5

In this case, we can add 3 to both sides of the equation to get x = 8.

Case 2: x - 3 = -5

In this case, we can add 3 to both sides of the equation to get x = -2.
