Karen earn a commission of $140.00 per course that you sell on the internet. She
sold 112 courses.
What is her commission?

Answers

Answer:

$ 15680

Step-by-step explanation:

From the question given above, we were told that Karen earn a commission of $ 140 per course.

To know her commission for selling 112 courses, we simply do the following:

Karen earn a commission of $ 140 for 1 course.

Therefore, she will ear $ X for 112 courses i.e

$ X = $ 140 × 112 course/ 1 course

$ X = $ 15680

Therefore, Karen commission for selling 112 courses is $ 15680

The following is a factor of the polynomial is x+2.

What is Factor theorem?

Factor theorem is a special kind of the polynomial remainder theorem that links the factors of a polynomial and its zeros.

The factor theorem removes all the known zeros from a given polynomial equation and leaves all the unknown zeros. The resultant polynomial has a lower degree in which the zeros can be easily found.

As per the factor theorem, (y – a) can be considered as a factor of the polynomial g(y) of degree n ≥ 1, if and only if g(a) = 0. Here, a is any real number. The formula of the factor theorem is g(y) = (y – a) q(y). It is important to note that all the following statements apply for any polynomial g(y):

(y – a) is a factor of g(y).g(a) = 0.The remainder becomes zero when g(y) is divided by (y – a).The solution to g(y) = 0 is a and the zero of the function g(y) is a.

Given:

f(x)=x³ + 12x² + 9x - 22

To the above equation (x + 2) is a factor of x³ + 12x² + 9x - 22.

As,

f(-2)= (-2)³ + 12(-2)² + 9(-2) - 22

f(x)= -8 + 48 -18 -22

f(x)= 40 -40

f(x) = 0

Hence, the factor of x+2

For every 1/150 square mile Xavier mows, Boa mows 1/120square miles. How many square miles does Xavier mow for every 1 square mile?

A. 3/5
B. 4/5
C. 5/4
D 15/17

Answers

Answer:

4/5

Step-by-step explanation:

step 1: Divide 1/150 by 1/120. (You should get 0.8)

step 2: convert 0.8 into a fraction over 10. (8/10)

step 3: simplify that fraction by dividing 8/10 by 2, which will give you your final answer, 4/5.

The required square miles that Xavier mow 4 / 5. Option B is correct.

Given that,
For every 1/150 square mile Xavier mows, Boa mows 1/120square miles, how many square miles does Xavier mow for every 1 square mile is to be determined.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Ration of Xavier to Boa = 1 / 150  /  1 / 120
                                       = 120 / 150
                                       = 12 / 15
                                        = 4 / 5

Thus,  the required square miles that Xavier mow 4 / 5. Option B is correct.

kelly is going to buy 12 items from Pablo's Food Truck. 1/6 of the items are tacos, 25% are empanadas, 1/3 are tamales and the rest are burritos. How many burritos did kelly buy?

Answers

Answer: 3 burritos

Step-by-step explanation:

Fraction of tacos = 1/6

Fraction of empanadas = 25% = 1/4

Fraction of tamales = 1/3

Fraction of burritos = 1 - (1/6 + 1/4 + 1/3)

It should be noted that the lowest common multiple for 6, 4 and 3 is 12.

Fraction of burritos = 1 - (1/6 + 1/4 + 1/3)

= 1 - (2/12 + 3/12 + 4/12)

= 1 - 9/12

= 3/12 or 1/4

The number of burritos bought by Kelly will now be:

= 1/4 × 12

= 3 burritos

Calculate the density of benzene if 0.10L has a mass of 36.4g.

Answers

Answer:

[tex]d=0.364\ g/cm^3[/tex]

Step-by-step explanation:

It is given that,

Mass of benzene, m = 0.1 L

Mass, m = 36.4 g

We know that, 1 L = 1000 cm³

0.1 L = 100 cm³

The density of an object is equal to its mass divided by its volume. So,

[tex]\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3[/tex]

So, the density of benzene is [tex]0.364\ g/cm^3[/tex].

sing the expression x + 3, write one equation that has one solution, one equation that has no solution, and one equation that has infinitely many solutions. Explain

Answers

Answer:  one solution  x + 3 = 5   x = 2   no other other value for x is possible

No solution:  (x + 3) = 2(x +3)  

Infinitely many solutions:  x+3 = 3 + x

Step-by-step explanation:

why (x + 3) = 2(x +3)  has no solution. Can you solve?

x+3=2x+6 -x=3 x=-3 substute -3 for x

(-3)+ 3)= 2[(-3) +3]

-3+3 = -6 +3

0 = -3 False!

x+3 = 3 + x  has infinitely many solutions. Substitute any number for x, and the equation is true   (5)+3=3+(5) 8=8 .  11111+3 =3+11111  11114=11114

An equation can either have: one solution, no solution, or infinitely many solutions. Some equations that can be derived from [tex]x + 3[/tex] and their solution type are:

[tex]x + 3 = 2x[/tex] has one solution[tex]x + 3 = x[/tex] has no solution[tex]x + 3 = 2(0.5x + 1.5)[/tex] has one solution

Given that:

[tex]Expression = x + 3[/tex]

Equation with one solution

For an equation to have one solution. then the equation is consistent and dependent.

For instance:

[tex]x + 3 = 2x[/tex]

Collect like terms to solve for x

[tex]2x -x = 3[/tex]

[tex]x =3[/tex]

This means that [tex]x =3[/tex] is the only solution to [tex]x + 3 = 2x[/tex].

Hence, [tex]x + 3 = 2x[/tex] has one solution

Equation with no solution

For an equation to have no solution. then both sides of the equation are not equal

For instance:

[tex]x + 3 = x[/tex]

Collect like terms to solve for x

[tex]x- x = 3[/tex]

[tex]0 = 3[/tex]

Because 0 is not equal to 3, then [tex]x + 3 = x[/tex] has no solution

Equation with infinitely many solutions

For an equation to have infinitely many solutions. then both sides of the equation must be the same thing

For instance:

[tex]x + 3 = 2(0.5x + 1.5)[/tex]

Open the bracket

[tex]x + 3 = x + 3[/tex]

Collect like terms

[tex]x - x = 3 - 3[/tex]

[tex]0 = 0[/tex]

Because both sides are the same (i.e. 0), then [tex]x + 3 = 2(0.5x + 1.5)[/tex] has infinitely many solutions

How long will it take for both trains to cross the finish line together the first time?

A
30 seconds

B
60 seconds

C
72 seconds

D
120 seconds

Answers

Answer:

60 seconds.

Step-by-step explanation:

We have been given that Maria train can go around the track in 10 seconds. Alma train can go around the track in 12 seconds.

To find the number of seconds after which both trains will cross the finish line together the first time we will find LCM of 10 and 12. LCM will give us the smallest positive integer that is divisible by both 10 and 12.  

Multiples of 10 are: 10, 20, 30, 40, 50, 60, 70,...    

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,..  

We can see that least common multiple of 10 and 12 is 60, therefore, it will take 60 seconds for both trains to cross the finish line together the first time.

A) Could Godric have five $20 bills given the information you know?Explain

B) Let n be the number of five dollar bills that Godric has. Set up an equation using n that models this situation and solve it for n

Answers

Answer:

A) Godric can have maximum of four $20 bills.

Therefore Godric can not have five $20 bills.

B) Equation is:

[tex]5n+20(11-n)=115[/tex]

[tex]n=7[/tex]

Step-by-step explanation:

Let the number of $5 bills with Godric = [tex]n[/tex]

Total number of bills = 11

Therefore, number of $20 bills = (11 - [tex]n[/tex])

Total amount of money in form of $5 bills = $[tex]5n[/tex]

Total amount of money in form of $20 bills = $[tex]20(11-n)[/tex]

Total money with Godric is $115.

[tex]\therefore 5n+20(11-n)=115\\\Rightarrow -15n=115-220\\\Rightarrow n=7[/tex]

Number of $5 bills present with Godric = 7

Number of $20 bills present with Godric = 11 - 7 = 4

A) Godric can have maximum of four $20 bills.

Therefore Godric can not have five $20 bills.

B) Equation is:

[tex]5n+20(11-n)=115[/tex]

Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
ara

Answers

Answer:

a7=-1

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences can be identified because each term n is obtained by adding or subtracting a fixed number to the previous term n-1.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

We know: a12=29, a16=53, now we use the above equation for n=12 and n=16:

[tex]a_1+(12-1)r=29[/tex]

[tex]a_1+(16-1)r=53[/tex]

Simplifying both equations:

[tex]a_1+11r=29[/tex]

[tex]a_1+15r=53[/tex]

Subtracting:

[tex]4r=53-29=24[/tex]

Solving:

r=24/4

r=6

The 7th term can be found as 9 terms before the 16th:

[tex]a_7=a_{16}-9r[/tex]

[tex]a_7=53-9*6=53-54=-1[/tex]

Thus: a7=-1
