I am probably just really dumb, but I don't understand the concept. The question is: -42v+33<8v+91. I am supposed to solve the inequality for v. Please give an explanation and not just an answer, I would really like to know how to do this.

Answers

Answer 1
Answer: -42v +33 <8v +91

Move all terms with V to the left side by subtracting 8V from both sides.

-50v +33 < 91

Now get the term with V all by itself by subtracting 33 from each side:

-50v<58

Solve for V by dividing both sides by -50  ( when dividing an inequality by a negative number you also need to reverse the direction of the inequality sign).

v >58/-50

Reduce the fraction and relocate the negative sign:

V >-29/25

Answers

Answer:

2400 + (0.05X) = 2900

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

Step-by-step explanation:

Since Liz earns a salary of $ 2,400 per month, plus a commission of 5% of her sales, and she wants to earn at least  $ 2,900 this month, to find amounts of sales that will meet her goal, the following equation must be solved:

5/100 = 0.05

2400 + (0.05X) = 2900

0.05X = 2900 - 2400

0.05X = 500

X = 500 / 0.05

X = 10,000

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

much was each eraser?

Answers

Answer:

$4

Step-by-step explanation:

First, 22-6=16, this isolates how much she spent on erasers alone

Then, 16/4=4, if she bought 4 erasers each one would have cost $4

Step-by-step explanation:

5 dollars and 5 cents.

Answer:

1. Y

2. N

3. N

4. N

Step-by-step explanation:

Let's use the second equation, since it seems to be easier to use.

To check if an ordered pair is a solution, plug it in to the equation.

1. -10+18=8 --> Y

2. 25-12=13 --> N

3. 0-9=-9 --> N

4. 35-27=8 --> N

Edit : The 4th equation doesn't work for the first equation, whereas the first one still does.

Answer:

(-2,-6)

Step-by-step explanation:

-9x +2y = 6

5x - 3y = 8

1) Make one of the coefficients the same - y.

-9x +2y = 6 * 3

5x - 3y = 8 * 3

-27x +6y = 18

10x - 6y = 16

2) Add the new equations.

(-27x +6y = 18) + (10x - 6y = 16)

(-27x +6y) + (10x - 6y) = 18 + 16

-17x = 34

3) Divide to find the value of x

-17x = 34

x = 34/-17

x = -2

4) Substitute x into either equation to find the value of y.

-9(-2) +2y = 6

18 +2y = 6

2y = -12

y = -12/2

y = -6

5(-2) - 3y = 8

-10 - 3y = 8

-3y = 18

y = 18/-3

y = -6

Your answer is (-2,-6).

Determine the validity of the following argument: For students to do well in a discrete mathematics course, it is necessary that they study hard. Students who do well in courses do not skip classes. Students who study hard do well in courses. Therefore students who do well in a discrete mathematics course do not skip class.

Answers

Answer: True

Step-by-step explanation:

Let p= Students who do well in course do not skip class

q= Student who study hard do well in course

So p^q= Student who study hard and who do well in course do not skip class.

If p= true and q=true then p^q= true by discrete maths.

The argument is valid because the conclusion is logically derived from the provided premises. However, it is important to note that the validity of an argument does not guarantee the truth of its premises. The argument may be valid, but its premises could still be false.

The argument provided is valid.

The reasoning follows a valid logicalstructure, specifically a form of argument called a syllogism, where conclusions are drawn from two or more premises. Let's break it down:

"For students to do well in a discrete mathematics course, it is necessary that they study hard." This is a premise, stating that studying hard is a necessary condition for success in a discrete mathematics course.

"Students who do well in courses do not skip classes." This is another premise, suggesting that students who perform well in their courses do not miss classes.

"Students who study hard do well in courses." This is also a premise, indicating that diligent study leads to success in courses.

The conclusion drawn is: "Therefore students who do well in a discrete mathematics course do not skip class." This conclusion logically follows from the given premises. If we accept the truth of the premises, we must also accept the truth of the conclusion.

Suppose that two cards are randomly selected from a standard​ 52-card deck. ​(a) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done without​ replacement? ​(b) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done with​ replacement?

Answers

Answer:

(a)(1)/(17) (b) (1)/(16)

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard​ 52 card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without​ replacement? ​(b) What is the probability that the first card is a club and the second card is a club if the sampling is done with​ replacement.

SOLUTION:

(a)

Probability that first card is club P(A)=\frac{\text{total club cards}}{\text{total cards}}

                                                   =(13)/(52)

                                                   =(1)/(4)

As sampling is done without replacement.

probability that second card is club  P(B)=\frac{\text{total club cards}}{\text{total cards}}

                                                            =(12)/(51)

                                                            =(4)/(17)

Probability that first card is club and second card is club =P(A)* P(B)

                                                                                             =(1)/(4)*(4)/(17)=(1)/(17)

(b)

Probability that first card is club P(A)=\frac{\text{total club cards}}{\text{total cards}}

                                                   =(13)/(52)

                                                   =(1)/(4)

As sampling is done with replacement.

probability that second card is club  P(B)=\frac{\text{total club cards}}{\text{total cards}}

                                                            =(13)/(52)

                                                            =(1)/(4)

Probability that first card is club and second card is club =P(A)* P(B)

                                                                                             =(1)/(4)*(1)/(4)=(1)/(16)

The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an earthquake wave (also known as the intensity of an earthquake) to the amplitude of the smallest detectable wave. If we denote the magnitude of the earthquake by R, the intensity (also known as the amplitude of the earthquake wave) of the earthquake by A, and the amplitude of the smallest detectable wave by S, then we can model these values by the formula R=log(AS) In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8. Many pundits claim that the worst is yet to come, with an earthquake 748,180 times as intense as the 1906 earthquake ready to hit San Francisco. If the pundits ability to predict such earthquakes were correct, what would be the magnitude of their claimed earthquake? Round your answer to the nearest tenth.
