Adding 9 to both sides of the equation we have:

a/5 + 9 = 8 + 9 + 9

It's evident that a/5 + 9 is not equal to 8 + 9, but to 8+9+9 instead.

The length of base is l = 5.

The width of base is b = 4.

The volume of pyramid is V = 60.

The formula for the volume of the pyramid is,

[tex]V=\frac{1}{3}l\cdot b\cdot h[/tex]

Factor the following polynomials. Remember, factoring strategies for quadratic polynomials may be needed here.

Answers

For this problem, we are given a polynomial, and we need to factor it.

The polynomial is given below:

We can use the difference between two squares to factor this polynomial. The base form of this notable product is shown below:

[tex]\begin{gathered} (a-b)(a+b)=a^2-b^2\\ \\ \end{gathered}[/tex]

We can do the same with the original polynomial:

Answer:

The number is not a square number because the exponent is an odd number.

Step-by-step explanation:

Square numbers or perfect squares are any numbers that once put to the square root equals a whole number. Such as 4 is a square number because the square root of 4 is 2 or 2 to the second power. Numbers that are raised to even powers also fall under this rule. For example, 16 is a square number as it is equal to 2 to the fourth power, or 16 to the fourth root is 2. Since 1953125 can also be written by 5 to the ninth power it does not go under this rule due to the power being 9.  9 is an odd number. For it to be a perfect square the exponent would have to be an even number.

Kimberly has an empty cardboard box that weighs 0.5 pounds. She puts 10 loaves of bread and a 4-pound jar of peanut butter in the box. The total weight of the box and its contents is 19.5 pounds. One way to represent this situation is with the equation 0.5 - 106 + 4 = 19.5 In this situation, what does the solution to the equation represent? In other words, if you solved for b. what would the value of b tell you? You do not have to find the solution to answer the question

Answers

The equation is represented by:

0.5 + 10b + 4 = 19.5

In which 19.5 is the total weight of the box and it's contents.

0.5 is the weight of the cardboard box.

4 is the weight of the jar of peanut butter.

10b is the weight of all loaves of bread.

And b is the weight of a single loaf of bread

The answer is:

The solution of the equation, which is the value of b, represents the weight of a single loaf of bread.

Assume that a particular professional baseball team has 10 pitchers, 6 Infielders, and 9 other players. If 3 players' names are selected at random determine the probability that 2 are pitchers and 1 is an infielderWhat is the probability of selecting 2 pitchers and 1 infielder?Type an integer or a simplified fraction)

Answers

The probability of choosing 2 pitcher and one infielder out of the total number of player can be obtained as follows:

We need to slect two pitchers and one infielder out of 10 pitchers and 6 infielders, the number of ways we can do this is:

[tex](_{10}C_2)(_6C_1)=270[/tex]

Out of the 25 players if we choose 3 we can do this in the following number of possibilities:

[tex]_{25}C_3=2300[/tex]

Then the probability is:

[tex]P=\frac{270}{2300}=\frac{27}{230}[/tex]

Therefore, the probability of choosing 2 pitchers and one infielder is 27/230.

The rat population in major metropolitan city is given by the formula n(t)=40e^0.015t where t is measured in years since 1991 and n(t) is measured in millions. What does the model predict the rat population was in the year 2008?

Answers

To use the model we need to find the value of t. To do this we substract the year we want to know from the year the model began, then:

[tex]t=2008-1991=17[/tex]

Now that we have t we plug it in the function:

[tex]n(17)=40e^{0.015\cdot17}=51.618[/tex]

Therefore the model predict that there were 51.618 millions of rats in 2008.

Determine the X intercepts of the para bola whose graph is given below write your answer as ordered pairs separated by a comma if necessary

Answers

Answer:

The x-intercepts are (-1, 0) and (4, 0)

Explanation:

Given:

A graph of a parabola

To find:

the x-intercepts of the parabola in ordered pairs

The x-intercept is the value of x when y = 0

On a graph, it is the value of x when the line crosses the x-axis

The line crosses the x axis at x = -1 and x = 4

The x intercept in ordered pairs will be in the form (x, y)

when x = -1, y = 0

when x = 4, y = 0

The x-intercepts are (-1, 0) and (4, 0)

Explanation:

Given:

[tex]\left\{\begin{array}{l} y<-2 x+3 \\ y \geq x-4 \end{array}\right.[/tex]

The second inequality in the system is:

[tex]y\geq x-4[/tex]

The intercepts of the boundary line (y=x-4) are (0, -4) and (4,0).

Since the inequality has an equal to sign attached, we use a solid line.

At (0,0)

[tex]\begin{gathered} y\geq x-4 \\ 0\geq-4 \end{gathered}[/tex]

Since the inequality 0≥-4 is true, shade the side that contains (0, 0) as shown in the graph below:

So, we use a solid line and shade above the boundary line.

Determine the value of k for which f(x) is continuous.

Answers

These are the conditions of the continuity in a function:

First, the value of x must have an image.

Second, the lateral limits must be equal:

[tex]\lim_{x\to a^+}f(x)=\lim_{x\to a^-}f(x)[/tex]

Finally, the value of the limit must be equal to the image of x. This means that:

[tex]f(a)=\lim_{x\to a^}f(x)[/tex]

In this case, we must find a value of k that can make the two lateral limits equal in x =3:

[tex]\lim_{x\to3^+}x^2+k=\lim_{x\to3^-}kx+5[/tex]

We can solve these two limits easily by replacing the x with the value of 3

[tex]3^2+k=3k+5[/tex][tex]\begin{gathered} 9+k=3k+5 \\ 4=2k \\ k=2 \end{gathered}[/tex]

Finally, we can see that the answer is k=2.

Answers

Sam's school and the library are actually 420m apart.

What is the Scale Drawing?

A scale drawing is a more compact representation of the original image, structure, or object.

The town is depicted at scale on the town map.

Original dimensions divided by the scale drawing's dimensions gives the drawing's scale.

The first step is to establish the map's scale in order to calculate the precise distance between Sam's school and the library.

Map scale: 250 m / 5 cm = 50

In this scale, 1 cm equals 50 m.

Scale of the drawing times the distance on the map equals the actual distance between Sam's school and the library.

50 x 8.4 = 420m

Answers

yes, 5/6 as a decimal is 0.83

How many solutions does the system formed by x − y = 4 and ay − ax + 4a = 0 have for a nonzero number a? Give your answer and complete the explanation.

Answers

Given system of equations have no solutions that is nonzero.

We have been given the system of equations formed by x − y = 4 and   ay - ax + 4a = 0

We need to find the number of non-zero solutions the system have for a nonzero number 'a'

x - y = 4          ............(1)

ay - ax + 4a = 0            ............(2)

From equation (1),

x = 4 + y

Substitute x = 4 + y in equation (2),

ay - a(4 + y) + 4a = 0  

ay - 4a - ay + 4a = 0  

-4a + 4a = 0

0 = 0

This means that the system have no solutions that is nonzero.

Therefore, given system of equations have no solutions that is nonzero.
