a 12 inch pizza is divided into 10 slices. what is the length of the crust from one slice?

Answer:

Below

Step-by-step explanation:

x = first number  

x+1 = second number

x *  (x+1) = 272

x^2  +x  = 272

x^2 + x - 272 = 0     Use Quadratic Formula to find:

x=   16    x+1 = 17          OR       x =   -17     x+1 = -16

Answer:

Percentile = 90

Therefore, the test score 12 is at the 90th percentile.

Step-by-step explanation:

Percentile = (Number of scores less than or equal to score) / (Total number of scores) * 100

Percentile = (9) / (10) * 100

Answer:

Percentile = 90Therefore, the test score 12 is at the 90th percentile

Percentile = (Number of scores less than or equal to score) / (Total number of scores) * 100Percentile = (9) / (10) * 100Step-by-step explanation:

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Consider that on a coordinate plane-xy, the x-values increase from left to right, and y-values increase from bottom to up.

Given that the linear graph passes through (1,1).

It is given that the graph goes 3 units up for every 2 units right. This can also be understood as the graph goes 3 units down for every 2 units left.

From the point (1,1), the x-value corresponding to 2 units left is given by,

x=1-2

x= -1

Similarly, from the point (1,1), the y-value corresponding to 3 units down is given by,

y = 1 - 3

y= -2

So the point (-1,-2) must also lie on the same linear graph.

Therefore, option (b) is the correct choice.

Answer:

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

Step-by-step explanation:

To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.

One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:

-27 and 1

-9 and 3

-3 and 9

-1 and 27

We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:

3z^2 + 26z - 9 = (3z - 1)(z + 9)

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.

A square has it's sides equal

A = l²

The area of 2 walls = 128/2 = 64

Therefore the length of each sides = √64

= 4meters

To find out how much black cord the design needs, we must find the perimeter of the figures. In this case, it would be: 107.42ft

To find the perimeter of four-sided figures, we just have to add the length of their sides as shown below:

To find the area of the triangle we must add its sides, in this case it is a triangle that has all the sides equal so it would be like this:

2ft + 2ft + 2ft = 6ft

Finally, the perimeter of the circle is calculated by multiplying 2 * number pi * radius. So the operation would look like this:

2*3.14*1.5=9.42ft

Now all that remains is to add all the sides and we will know how much black cord we need

9.42ft + 24ft + 28ft + 52ft = 107.42ft

Additionally, the area of the figures is calculated as follows:

The distance from the top left corner of the foundation to the bottom right corner is 27 meters.

The distance between two points in space can be calculated using the Pythagorean theorem. In this case, we want to find the distance from the top left corner of the foundation to the bottom right corner.

To do this, we will use the length and width of the foundation, which are 20 meters and 18 meters respectively.

The Pythagorean theorem states that in a right triangle, the square of the distance (c) between the two points is equal to the sum of the squares of the other two sides (a and b). Mathematically, this can be represented as

=> c² = a² + b².

In our case, the two sides are the length (20m) and width (18m) of the foundation. To find the distance, we will first find the square of c by adding the squares of a and b. So,

=> c² = 20² + 18² = 400 + 324 = 724.

To find the distance, we will take the square root of c².

So,

c = √724 = 26.83

When we rounded to the nearest meter, c = 27m.

Answer:

To approximate the solution to the system of equations, we need to find the point where the two lines intersect. From the second equation, we know that y = (1/2)x + 1. Substituting this expression for y into the first equation gives:

3x + 2[(1/2)x + 1] = -4

Simplifying and solving for x, we get:

3x + x + 2 = -4

4x = -6

x = -1.5

Substituting this value of x back into the second equation gives:

y = (1/2)(-1.5) + 1 = 0.25

Therefore, the solution to the system of equations is approximately (-1.5, 0.25).

So the answer is (−1.5, 0.25).

The perimeter of a regular decagon with sides 5√6 is 50√6 ( option A)

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

The perimeter of a shape is obtained by adding all the sides together.

Therefore, if one side is 5√6 inches, a decagon which is of 10sides will have 5√6 inches at all it's sides because it is a regular polygon.

Therefore P= 5√6 × 10

P = 50√6 inches.

The fraction of crayons that are blue triangle is 1/5.

The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs

A fraction represents a part of a whole.

1. Let's say Alexa had a total of 5x crayons in the bag.

the number of blue crayons in the bag is 2x,

There is one triangle for every two round crayons,

(1/2) × 2x = x (By condition)

So, the fraction of crayons that are blue triangle is x / 5x = 1/5.

The number of blue round crayons is 2x.

The number of non-blue crayons is 5x - 2x = 3x,

The ratio of blue rounds to non-blue crayons is 2x / 3x = 2/3.

2.

4 out of 5 wall footballs are rubber, 4/5 of the footballs in the bag are rubber.

The fraction of rubber footballs that are brown is 2/3.

The fraction of footballs that are brown rubber footballs is (4/5) × (2/3) = 8/15.

The fraction of non-brown rubber footballs is (4/5) - (8/15) = 4/15.

The ratio of rubber footballs to non-rubber footballs is (4/5) / (1/5) = 4.

So there are 4 times as many rubber footballs as non-rubber footballs

Hence,  the fraction of crayons that are blue triangle is 1/5.

Step-by-step explanation:

If you spin the spinner 75 times, the expected number of 2's is 15.

Since the spinner has 5 spots ranging from 1-5, the probability of getting a 2 on any given spin is 1/5.

Therefore, if you spin the spinner 75 times, the expected number of 2's is: (1/5) * 75 = 15

So, if you spin the spinner 75 times, you can expect to get 15 2's.

Probability itself has a number from 0 to 1.

The probability value is 0 (zero) for an event that is impossible or unlikely to occur, for example, cows laying eggs.

In the given situation, the required value of x for the given pair of adjacent angles is 30°.

When two angles have a similar vertex and side, they are referred to as neighboring angles.

The vertex of an angle is the point at which the rays that make up its sides come to an end.

When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.

The definition of adjacent is next to or nearby.

Two next-door residences are an illustration of proximity.

Typically, we think of those who live on our street as neighbors.

So, we have:

x + x + 30 = 90

Now, solve for x as follows:

x + x + 30 = 90

2x + 30 = 90

2x = 90 - 30

2x = 60

x = 60/2

x = 30

Therefore, in the given situation, the required value of x for the given pair of adjacent angles is 30°.

____ The given question is not correct, the correct question is given below:

What is happening after Time (T e )? There are three correct statements.

Answer:

1/4

Step-by-step explanation:

You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).

Here the denominators are 2 and 4 so the LCM is 4.

After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.

So convert both 1/2 and 1/4

1/4 x 1/1 = 1/4

1/2 x 2/2 = 2/4

Now we can just subtract the numerator from each other.

2/4 - 1/4 = 1/4

We cannot simplify the difference any more so keep it the same.
