Answer:

10% profit

Step-by-step explanation:

since the item was sold for more than it cost, this is a profit

percent profit = [tex]\frac{P}{C}[/tex] × 100%

profit P = SP - CP = Rs 220 - Rs 200 = Rs 20 , then

% profit = [tex]\frac{20}{200}[/tex] × 100% = 0.1 × 100% = 10%

Answer:

Add like terms

4a² + 4ab + b²

Now, let's add the amount for the items bought

a² –ab -b²  + 2a² +8ab-2b² + a² –3ab + 4b²

add like terms

4a² +  4ab + b²

Answer:

  -8/3

Step-by-step explanation:

You want the slope of the line shown in the graph.

Whether counting grid squares on the graph, or using the slope formula, it is convenient to choose two points on the grid where the line crosses the intersection of grid lines.

It appears, the line passes through grid points (1, 4) and (4, -4). Using the slope formula, we find the slope of the line to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (-4 -4)/(4 -1) = -8/3

The slope of the line is -8/3.

The slope is the ratio of "rise" to "run" for the line. From the two points we see where the line crosses grid intersections, we have a "rise" of -1 from y=4 to y=-4, and a "run" of 3 from x=1 to x=4.

  rise/run = -8/3 = slope of the line

The statement which is true about the system of three linear equations is that: B. the system can be either inconsistent and independent or consistent and dependent.

A system of three linear equations can be defined as a type of algebraic equation of the first order that has three (3) variables with each of its term having an exponent of one (1).

In Mathematics, a system of three linear equations is considered as a consistent system when it has at least one solution. However, a system of three linear equations is considered as an inconsistent system when it has no real solution.

Additionally, a system of three linear equations is considered as an independent system when it possesses exactly one solution while it is a dependent system if it has an infinite number of solutions.

The surface area of the figure is calculated as 150.72 [tex]mi^2[/tex] and when rounded off to the nearest hundredth, it comes out as 151 [tex]mi^2[/tex].

A solid object's surface area can be stated as a measurement of the overall space that the object's surface takes up. As an alternate, surface area can also be described as the area of the entire outer part, or which is said as the uppermost layer of any kind of 3D object.

Square units are used in the calculation. The total area of all the outside surfaces makes up the surface area of a three-dimensional object, which is also expressed in square units.

As an example, we can take that in order to find the exact surface area of a cuboid, we have to add the areas of all 6 faces.

In this figure, we can see that it can be stated as a cylinder.

So, as we know the formula of the surface area of a cylinder can be written as:

2[tex]\pi[/tex]rh + 2[tex]\pi r^2[/tex]

Here r = 8/2

=4 mi

h = 2 mi

Thus, putting the values, we have,

Surface area = [2 x 3.14 x 4 x 2] + [2 x 3.14 x 4 x 4]

= 50.24 + 100.48

The fraction of Jena's income does she plan to spend each month on these two items together is 1/2

Amount of Jena's income spent on savings = 1/3 × $3800

= 1266.666666666666

Approximately,

= $1,266.67

Amount of Jena's income spent on groceries = 1/6 × $3800

= 633.3333333333333

Approximately,

= $633.33

Amount spent on the two items = $1,266.67 + $633.33

= $1900

Fraction of Jena's income spent on the two items = 1/3 + 1/6

= (2+1) / 6

= 3/6

= 1/2

So therefore, Jena spent 1/2 of her income on savings and groceries.

The average rate of change of the function is found as 1.

For the given question;

The function is given by the equation;

g(x) = -x² - 9x + 27

The interval of the function lies as;

-9 ≤ x ≤ -1.

Let,

a = -1 ans b = -9

Then,

g(a) = g(-1), Put x = -1 in the function.

g(-1) = -(-1)² - 9(-1) + 27

g(-1) = 35

Now, g(b) = g(-9), Put x = -9 in the function.

g(-9) = -(-9)² - 9(-9) + 27

g(-9) = 27

Thus, the average rate of change of the function is-

Average rate of change = [g(a) - g(b)]/[a - b]

= [35 - 27]/[-1 + 9]

= 8/8

= 1

Thus, the average rate of change of the function is found as 1.

A transformative sequence is a particular arrangement of transforming events. This suggests that a series of transformations may manage more than one transition, and that the order in which they occur is crucial. A and B are similar in this case.

When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.

Formally, two sets of points are said to be congruent if, and only if, an isometry, which is a collection of rigid motions including translation, rotation, and reflection, can transform them into one another.

This shows that resizing an object will not allow it to be properly aligned with another object, only by moving and reflecting it. Therefore, two independent plane figures on a piece of paper are congruent if we can cut them out and then precisely line them up. The paper might be distributed.

Each box is the same size in terms of length and width. The only change is where the figure is located.

Transformations can be divided into four categories: translation, rotation, reflection, and dilation.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Congruent refers to things that are exactly the same size and shape.

Hence, A and B are congruent.

Explanation:

The probability of red and purple can be calculated as the frequency for rean and purple over the total frequency

Red has a frequency of 4

Orange has a frequency of 1

Yellow has a frequency of 1

Green has a frequency of 7

Blue has a frequency of 1

Purple has a frequency of 2

The total frequency is

4 + 1 + 1 + 7 + 1 + 2 = 16

And the frequency for red and purple is

4 + 2 = 6

Then, the probability is equal to

P = 6/16 = 0.375
