X=6x+30/x

Step-by-step explanation:

just simplify

Answer:

x = 3 ± √(39)

Step-by-step explanation:

x            6

-----   = -------

(x+5)      x

We can solve using cross products

x * x = 6(x+5)

x^2 = 6x+30

Subtract 6x from each side

x^2 -6x= 6x+30-6x

x^2 -6x= 30

Subtract 30 from each side

x^2 -6x -30 = 30-30

x^2 -6x -30 =0

Using the quadratic formula

x = -b ± √(b^2 -4ac)

     -------------------------

                2a

where  a=1  b = -6  and c = -30

x = -(-6) ± √((-6)^2 -4(1)(-30))

     -------------------------

                2(1)

x = 6 ± √(36 +120)

     -------------------------

                2

x = 6 ± √(156)

     -------------------------

               2

x = 6 ± √(4*39)

     -------------------------

                2

x = 6 ± 2√(39)

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 370 minutes, the monthly cost will be $76. If the customer uses 750 minutes, the monthly cost will be $114.

(370,76) and (750,114)

A) Find an equation in the form y=mx+b, where x is the number of monthly minutes used and y is the total months of the Regular plan.

slope =[tex]\frac{(114-76}{(750-370)}[/tex] = [tex]\frac{38}{380}[/tex] = [tex]\frac{1}{10}[/tex]√

y = MX + b

Solve for "b"

114 = (    [tex]\frac{1}{10}[/tex])750 + b

114 = 75 + b

b = 39

Answer:: y = ([tex]\frac{1}{10}[/tex])x +39

Customers and customers may or may not be the same thing, but they are two different things. A customer uses the products that a customer has purchased. An ultimate client could also be a consumer, but they might also have bought things for someone else to consume. A middle customer is not at all a consumer. The situation is rather convoluted because final consumers of so-called industrial goods and services are theoretically also consumers because they either consume the goods and services individually or incorporate them into other finished products. They are more frequently referred to as industrial customer or business-to-business customers instead. Similar to how few people refer to clients who purchase services as consumers

The minimum score you need on the fourth test to get a B is 146.

To get a B, you need to get an average of 80% in all four scores.

The first 3 tests have a total of 100 points, and you got:

79, 77, and 91

So the percentage that you got in these 3 tests is:

79%, 77%, 91%

Now, let's say that X is the percentage you get in the last test, we must have that the average is 80%, then:

(79% + 77% + 91% + X)/4 = 80%

Solving that for x, we will get:

X = 4*80% - $79 - 77% - 91% = 73%

So you need to get at least a 73% of the last test, and that test has 200 points, so you need to get:

P = 0.73*200 = 146

Probability of getting a 2 or even(4) is expected outcomes divided by total outcomes(4). The answer is P(2 or even)= 2/4 = 1/2.

A fair spinner is used with four equal sections numbered 1,2,3,4.

Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. Probability of an Event. Assume an event E can occur in r ways out of a sum of n probable or possible equally likely ways. Then the probability of happening of the event or its success is expressed as; P(E) = r/n. The probability that the event will not occur or known as its failure is expressed as: P(E’) = (n-r)/n = 1-(r/n).

P(2) = expected outcomes/total number of outcomes

=> 1/4

P( even:4) = 1/4

So; P(2 or even)= 1/4 + 1/4 = 2/4 or 1/2

Answer:

Expected results are divided by total outcomes to determine the probability of getting a 2 or even (4). (4). P(2 or even) = 2/4 = 1/2 is the response.

Step-by-step explanation:

There are four equal portions on a fair spinner, designated 1, 2, 3, and 4.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution. the likelihood of an event. Assume that there are n probable or plausible equally likely ways for an event E to occur. Then, P(E) = r/n is used to represent the likelihood that the event will occur or that it will be successful. P(E') = (n-r)/n = 1-(r/n) denotes the chance that the event will not occur, also known as its failure.

P(2) = expected outcomes/total number of outcomes

=> 1/4

P( even:4) = 1/4

So; P(2 or even)= 1/4 + 1/4 = 2/4 or 1/2

hmmm when it comes to doing operations with decimals, we can hmmm say for this case, the product, we can just toss the dot and perform the multiplication straight up with only 4099 * 21, and then we'll include the decimal point.

One popular rule of thumb is the 30% rule,

which says to spend around 30% of your gross income on rent.

So if you earn $2,800 per month before taxes,

you should spend about $840 per month on rent.

To calculate,

simply divide your annual gross income by 40 - if you make $120,000 a year, you can spend $3,000 on rent.

An equivalent is the 30% rule, meaning that you can put 30% of your annual gross income in rent.

If you make $90,000 a year, you can spend $27,000 on rent, and so your monthly rent will be $2,250.

For example, for a home valued at $250,000, a landlord could charge between $2,000 and $2,750 each month.

If your home is worth $100,000 or less, it's best to charge rent that's close to 1% of its value.

To determine daily rent, the total number of days are divided by the monthly rent.

To get an appropriate calculation for how much each roommate should pay depending on the size of their room, take the square footage of each room and divide by the total square footage of the apartment. This will give you a percentage for the size and value of each room, which you can apply to the total cost of rent.

Using the relation between velocity, distance and time, it is found that the penny has a faster unit rate per hour. It travels about 56.4 kilometers per hour faster.

Velocity is distance divided by time, that is:

v = d/t.

The rocket traveled 208 kilometers in 50 minutes = 5/6 of an hour, hence it's velocity, which is the unit rate, is given by:

v = 208/(5/6) = 208 x 6/5 = 249.6 km/hour.

The penny travels 153 kilometers in a half an hour, hence it's velocity is given by:

v = 153/0.5 = 306.

306 > 249.6, 306 - 249.6 = 56.4, hence:

The penny has a faster unit rate per hour. It travels about 56.4 kilometers per hour faster.

The market equilibrium point will be at a price of 70 and the quantity of 80.

From the information, the supply and demand for a product are given by 2p − q = 60 and pq = 100 + 25q.

From 2p − q = 60

q = 2p - 60

Substituting this in pq = 100 + 25q.

p(2p - 60) = 100 + 25(2p - 60)

2p² - 70p = 100 + 50p - 1500

2p² - 70p - 50p - 100 + 1500 = 0

2p² - 120p + 1400 = 0

Divide through by 2

p² - 60p + 700 = 0

p² - 70p + 10p - 700 = 0

p(p - 70) + 10(p - 70) = 0

p - 70 = 0

p = 0 + 70 = 70

Since 2p − q = 60

2(70) - q = 60

140 - q = 60

q= 140 - 60 = 80

Therefore, the market equilibrium point will be at a price of 70 and the quantity of 80.

A cartesian plane is a plane with two axes namely x axis and y axis.

A Cartesian plane is a graph with one x-axis and one y-axis and thus is also sometimes known as a x y graph.

These two axes are perpendicular to each other that is they form an angle of 90° with each other.

The origin (O) is in the exact center of the graph and is the point where the two axes intersect.

Numbers to the right of the zero on the x-axis are positive and the numbers to the left of zero are negative. ( as the case in number line as well)

Similarly, the number on the top of the center on y axis are positive and the numbers below are negative.

It can be used to represent any 2 D figure.
