Select the correct answer.
Solve the following compound inequality.
2x − 2 > -8 or -4x ≤ -36

In order to make profit of 1,200,000, the company should publish 180 copies of magazine.

The formula for the profit is given by:

Profit = revenues - total cost.

Meanwhile, the total cost consists of fixed cost and variable cost.

Total cost = fixed cost + price per unit x number of units sold

Parameters given in the problem:

Fixed cost = 600,000

variable cost = 50,000 per unit

selling price = 60,000 per copy

profit = 1,200,000

Let q be the number of copies sold, then:

Revenues = 60,000 q

Total cost = 600,000 + 50,000 q

Profit = 60,000 q - (600,000 + 50,000 q)

1,200,000 = 60,000 q - (600,000 + 50,000 q)

10,000 q = 1,800,000

q = 1,800,000 / 10,000 = 180

Edit:

The standard form would be:

3y = 20 - 4x

or

3y = -4x + 20

Answer/Step-by-step explanation:

Standard form of the equation should be in the form:

Ax + By = C

A, B and C must be whole numbers not fractions or decimals. B and C can be negative, but A must be positive.

Correctly written in standard form, this equation just needs one small tweak, multiply the whole thing by -1 to change all the signs so that the A will be positive.

-4x + 3y = 20

-1(-4x + 3y = 20)



4x - 3y = -20 this is proper standard form.

The required height of the cliff is  5√3/(√3)-1.

The angle of depression is defined as the If a human looks down at an object, then the angle of depression of that human is the angle between the horizontal line of sight and the object.

we have, angle of depression to top of pole = 45°

that of to foot of pole = 60°

Height of pole is 5 meter.

Then distance between tower is = 5+x/√3        ∴  tan(theta)=P/B

and, tan(45) = x/5+x/√3 = √3x/5+x   =1               ∴  tan(45) =1

5+x =√3x

X = 5/(√3)-1

Now height of cliff = 5+5/(√3)-1 = 5√3/(√3)-1 meter

Thus, the height of cliff is  5√3/(√3)-1.

The probability of outcome to be a 5 is 1/13. The probability of outcome not be 5 is 12/13. The probability of outcome to be a diamond or a king is 4/13. The probability of the outcomes to be a jack or a queen is 2/13. The probability of The outcome to be a heart and a club is 0 and the probability of the outcomes to be a card greater than 6 and less than 9 is  2/13.

A deck contains a total of 52 cards.

Total outcomes if the selected number of cards is one=52

Case A:

Each suit contain one 5 numbered card. There are four suits. Therefore, The required outcome would be 4.

Probability of an outcome is the ratio of desired outcomes to the total outcomes.

The probability of outcome to be 5, P(A):
P(A)=4/52

P(A)=1/13

Case B:

The total probability of outcomes=52/52=1

The probability of the outcome to be 5=1/13

Therefore, the probability of the outcome not to be 5, P(B):

P(B)=1-(1/13)

P(B)=12/13

Case C:

Each suit carries a king. Therefore, the probability of the outcome to be a king, P(M):

P(M)=4/52

P(M)=1/13

A suit carries 13 cards. Therefore, there will be 13 cards of diamonds.

The probability of the outcome to be a diamond, P(N):

P(N)=13/52

P(N)=1/4

The probability that the outcome is a king of diamonds, P(M[tex]\cap[/tex]N):

P(M[tex]\cap[/tex]N)=1/52

Hence, the probability that the outcome is a diamond or a king, P(M[tex]\cup[/tex]N):

P(M[tex]\cup[/tex]N)=P(M)+P(N)-P(M[tex]\cap[/tex]N)

P(M[tex]\cup[/tex]N)=(1/13)+(1/4)-(1/52)

P(M[tex]\cup[/tex]N)=16/52

P(M[tex]\cup[/tex]N)=4/13

Case D:

Each suit carries a Jack. Therefore, the probability of the outcome to be a jack, P(P):

P(P)=4/52

P(P)=1/13

Each suit carries a Queen. Therefore, the probability of the outcome to be a Queen, P(Q):

P(Q)=4/52

P(Q)=1/13

The probability that the outcome is a jack and a queen, P(P[tex]\cap[/tex]Q):

P(P[tex]\cap[/tex]Q)=0/52

P(P[tex]\cap[/tex]Q)=0

Hence, the probability that the outcome is a jack or a queen, P(P[tex]\cup[/tex]Q):

P(P[tex]\cup[/tex]Q)=P(P)+P(Q)-P(P[tex]\cap[/tex]Q)

P(P[tex]\cup[/tex]Q)=(1/13)+(1/13)-0

P(P[tex]\cup[/tex]Q)=2/13

Case E:

A card is never a heart and a club. Therefore, the probability of a card to be a heart and a club is 0.

Case F:

The numbers greater than 6 and less than 9 are the numbers between 6 and 9. The numbers between 6 and 9 are 7 and 8.

Each suit carries one 7 numbered card and one 8 numbered card. There is a total of 4 suits.

Therefore the desirable outcomes=8

The probability of the outcome required=8/52

Answer:

The percent being represented by the shaded area is [tex]175\%[/tex]

Step-by-step explanation:

The percent being represented by the shaded area can be calculated as follows

The first step is to evaluate the left square

Since each square represents one whole, and since the left square is all shaded in of [tex]4[/tex] then the percent being represented by the shaded area in the left square is

[tex]1=\frac{4}{4}=\frac{100}{100}=100\%[/tex]

The percent being represented by the shaded area in the first or the left square is [tex]100\%[/tex]

The second step is to evaluate the right square

Since the right or the second square is [tex]3[/tex] shaded in of [tex]4[/tex], then the fraction being represented by the shaded area in the second square is

[tex]\frac{3}{4}[/tex]

The third step is to convert [tex]\frac{3}{4}[/tex] into the percent form by the following equation

[tex]\frac{3}{4}=\frac{x}{100}[/tex]

Where [tex]x[/tex] is the percent value for the second square

Multiply both side by [tex]100[/tex] to isolate [tex]x[/tex]

[tex]\frac{3}{4}\times 100=\frac{x}{100}\times 100[/tex]

Simplify the equation

[tex]\frac{300}{4}=x[/tex]

Simplify the left side of the equation

[tex]75=x[/tex]

Since the value of [tex]x[/tex] is [tex]75[/tex], then the percent being represented by the shaded area in the second square is [tex]75\%[/tex]

The fourth step is to calculate the total percent being represented by the all shaded area

Since the total percent is the sum of the percent for the first square and the percent for the second square, then it follows

[tex]\text{Total percent}=100\%+75\%[/tex]

Simplify the equation

[tex]\text{Total percent}=175\%[/tex]

The distance from the base to the summit of the mountain is 3600 meters

The speed when going from base to summit = 45 meter / minute

The time taken for going from base to summit  = x minutes

The speed when descents from top to bottom = 60 meter / minute

The time taken for descents from top to bottom = x - 20 minutes

The speed = Distance / Time

The Distance = Speed × Time

Here in both case the distance is same

Then

45x = 60(x-20)

Solve the equation

45x = 60x - 1200

60x - 45x = 1200

15x = 1200

x = 1200/15

x = 80 minutes

Mamadou’s car used [tex]2\frac{2}{3}[/tex] gallons to travel 76 miles.

Now, we can easily find the distance covered by car in one gallon of gas but we will first convert the gas given from mixed fraction.

8/3 gallons of gas = 76 miles

Now, the distance covered in 1 gallon of gas can be found by dividing 76 by 8/3.

1 gallon of gas = 76/(8/3)

1 gallon of gas = 57/2 miles

1 gallon of gas = [tex]28\frac{1}{2}[/tex] miles or 28.5 miles

What is an arithmetic progression?

An arithmetic progression or arithmetic sequence is a number sequence in which the difference between consecutive terms is constant. For example, the sequence 5, 7, 9, 11, 13, 15.. is an arithmetic progression with a common difference of 2.

The first 'n' terms will be 1, 2, 3, 4, 5, 6, ...., n

The above sequence is an A.P. because it has a constant common difference of '1' between each consecutive number.

So a = 1, d = 1

By using the standard formula, we get

       [tex]S_n=\frac{n}{2}[2a+(n-1)d]\\\\S_n=\frac{n}{2}[2+(n-1)][/tex]

and for the last term

       [tex]t_n=a+(n-1)d\\\\t_n=1+(n-1)[/tex]
