A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 50 pounds
and each large box of paper weighs 80 pounds. There were 4 more large boxes
shipped than small boxes and the total weight of all boxes was 1750 pounds. Write a
system of equations that could be used to determine the number of small boxes
shipped and the number of large boxes shipped. Define the variables that you use to
write the system.

Answers

Answer 1

The system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped are:

50x+80y=1750

y = x+4 ,

where x represent the number of small boxes of paper and y represent the number of large boxes of paper.

We have:

Weight of small box of paper = 50 pounds

Weight of large box of paper = 80 pounds

Total weight of boxes = 1750 pounds

Let us consider that  the number of small boxes of papers be x.

The number of large boxes of papers be y.

Then, according to question

50x+80y=1750

y = x+4  

Therefore, the equations 50x+80y=1750 and y = x+4 can be used to determine the number of small boxes and large boxes of paper shipped.

where, x represent the number of small boxes of paper and y represent the number of large boxes of paper.

C $144.20
D $140.42
A $154.42
B $149.80

Answers

For groceries to be delivered, one particular grocery store charges 3% of the whole purchase price. The total price the store charges to deliver $140 worth of groceries will be $144.20.

What do you mean by percentage?

A % in mathematics is a quantity or ratio that is stated as a fraction of 100 (from the Latin per centum, "by a hundred"). Although abbreviations "pct.", "pct.", and occasionally "pc" are also used, percent symbol, "%," is frequently used to indicate it. A % lacks dimensions and has no associated unit of measurement.

It should be mentioned that a certain grocery store charges a delivery fee equal to 3% of the entire purchase price.

Consequently, the following is the total the store will charge to deliver $140 worth of groceries:

= Percentage charged × Cost+ Cost

= 3% × $140+$140

= 0.03 × $140+$140

= $4.20+$140

The amount charged is $144.20.

What is coordinate plane ?

A coordinate plane is a surface with two dimensions made up of two number lines. It is created when the origin, the point at which the X-axis and Y-axis cross, is reached. To locate points, one uses the numbers on a coordinate grid. A coordinate plane is useful for graphing points, lines, and many other things. It serves as a map and provides clear instructions for getting from one place to another

What are coordinates ?

Coordinates are a pair of numbers that identify a specific point on a coordinate plane, often known as a grid of coordinates. The ordered pair (x, y), which corresponds to the X-coordinate and the Y-coordinate, is expressed in parenthesis and is used to identify a point in a coordinate plane. Depending on where the point is in relation to the different quadrants, these coordinates may be positive, zero, or negative.

It is to be noted that the information for the completed table is given accordingly to show the perimeters in millimeters and in centimeters.

What is a Perimeter?

Perimeter simply refers to the total or sum of all the sides of a geometric shape. Note that the perimeter in units is obtained by counting the number of rectangles.

In the case of A:

Perimeter in Units = 10 Units.

Length is 60mm and width is 40mm
Perimeter = 30 + 20 + 30 + 20 = 100mm; and 10 cm

Recall that I cm = 10mm.

Hence, 100 /10 = 10 cm.

In the case of shape B:
Perimeter in Units = 41 Units.

Length is 400mm (that is 200 + 200)

Breath is 40mm (20 + 20)

Perimeter therefore is:

400 + 40 = 440mm
Perimeter in cm = 44

Recall, 10mm = 1cm

In the case of shape C:

Perimeter in Units = 36 Units.

Length is 10cm (that is 5 + 5)

Breath is 14mm (7 + 7)

Perimeter therefore is:

10+ 14 = 24cm
Perimeter in mm= 240

Recall, 10mm = 1cm

In the case of Shape D:

Perimeter in Units = 51 Units.

Length is 200mm (that is 100 + 100)

Breath is 100mm (50 + 50)

Perimeter therefore is:

200 + 100 = 300mm
Perimeter in cm= 230

Recall, 10mm = 1cm

In the case of Shape D:

Perimeter in Units = 53 Units.

Length is 260mm (that is 130 + 130)

Breath is 80mm (40 + 40)

Perimeter therefore is:

260 + 80 = 340mm
Perimeter in cm= 34

What is a simple interest applied to an amount?

Simple interest is the product of the principal amount, the rate and the time of investment

The amount Brayden deposited in the savings account, P= $2,700

The interest on savings account, R = 0.3% simple interest

The simple interest formula is, I = P•R•T

The interest in the account after each year is therefore;

1st year = $2,700×0.3%×1 = $8.7

The interest in 2 years, I = 2×$8.7 = $17.4

3 years, I = $8.7 × 3 = $26.1

4 years, I = $8.7 × 4 = $34.8

5 years, I = $8.7 × 5 = $43.5

The amount in the account after each of the 5 years are therefore;

1st year, A = $2,700 + $8.7 = $2,708.7

2nd year, A = $2,700 + $17.4 = $2,717.4

Write a linear equation of a slope intercept form for a line that passes through the point (-2, 9) and has a slope of:-5/2

Answers

Answer:

[tex]y = - \frac{5}{2} x + 4[/tex]

Step-by-step explanation:

The equation of a line in slope-intercept form is given by y= mx +c, where m is the slope and c is the y-intercept.

Start with the slope when forming the equation.

Given that the slope is [tex] - \frac{5}{2} [/tex], [tex]m = - \frac{5}{2} [/tex].

Substitute the value of m into the equation:

[tex]y = - \frac{5}{2} x + c[/tex]

The value of c can be found by substituting a pair of coordinates that the line passes through.

When x= -2, y= 9,

[tex]9 = - \frac{5}{2} ( - 2) + c[/tex]

9= 5 +c

c= 9 -5

c= 4

Thus, the equation of the line is [tex]\bf{y = - \frac{5}{2} x + 4}[/tex].

Measure of angle 1 = 159°
Measure of angle 2 = 21°
Measure of angle 3 = 159°
Measure of angle 4 = 21°

This is because of the reflexive property and that two angles that are next to each other equal 180°

Answer:

m<1 = 159° m<2 = 21° m<4 = 21°

Step-by-step explanation:

Since angle measure 3 was found, seeing that 3 and 1 are vertical angles (congruent) they equal the same, meaning angle measure 1 is also 159°. Also seeing that angle measure 3 and 2 are supplementary angles (2 or more angles that add up to 180°) subtracting 159° will give you 21°. Once again there are another set of verital angles, 2 and 4 making 4 also 21°

Answer: x = 80°, y = 50°

Step-by-step explanation:

We have an isosceles triangle.

As you can see, 130° lies on a straight line. A straight line = 180°.

The base angles of an isosceles triangle are equal. This means 180° - 130° = y.

So, y = 50°.

The total measures of any triangle is 180 degrees.

The total measure for the base angles here 100 degrees. That is, 50° + 50° =

Angle 2 is supplementary to Angle 3 Because it's given that to a supplementary to 3 lines A and B are parallel by the transverse line.

What are supplementary angles?

Two Angle whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

If ∠ 8 is supplementary to ∠ 9, then line x and y must be parallel lines wheres line s is the transverse line.

∠ 7 = ∠ 4.

Now, ∠ 7 = ∠ 2 and ∠ 4 = ∠ 9.

You, on the other hand, cant seem to get out of the beginner music book. You decide that your brother just has musical talent and you dont, and that no matter how hard you practice, youll never be as good as he is. But is that really true? Or are you just looking for an excuse to stop playing the piano?2 This is an argument that musicians and scientists love to revisit: Is musical ability an innate talent, or is it just the result of practice and determination? When someone is very good at a given thing, what is it that actually makes him good? asks Dr. K. Anders Ericsson, a psychology professor at Florida State University. Ericsson led a group of researchers in one of the most important studies about talent versus practice. Ericsson believes that two people can have the same ability to do something, such as play the piano, but the one who can engage in something called deliberate practice will be the one who becomes the most proficient.3 Deliberate practice isnt just logging in so many hours of practice time, but involves setting specific goals of skills the person needs to work on, getting immediate feedback, and concentrating on technique. Ericsson and his colleagues published a 900-page book called the Cambridge Handbook of Expertise and Expert Performance, in which they say that talent is overrated. They write that expert performers are made through practice and hard work, not simply born with amazing talent. They also suggest that if people pursue something that they love, they are more likely to work hard at it and be successful. Many people avoid doing things that they dont think theyre good at. They give up and tell themselves that they just dont have the talent. Instead, what they really dont have is the desire to be really good and the dedication to regularly practice to reach their goal.4 A lot of people believe there are some inherent limits they were born with, Ericsson says. But there is surprisingly little hard evidence that anyone could attain any kind of exceptional performance without spending a lot of time perfecting it.5 In his 2008 book Outliers, author Malcolm Gladwell summed up Ericssons work and repeatedly stated that anyone could become proficient and successful in his or her fieldincluding musicif they practiced for 10,000 hours, which he called the 10,000 Hour Rule. He writes that practice isnt the thing you do once youre good, but rather, the thing you do that makes you good. Even for those people who seem to have talent to start with, this amount of practice can make the difference between being average and being elite.6 Many scientists are questioning the entire idea of talent, calling it a myth. Folk psychologythe beliefs that people have about human behavior, usually handed down over generations as well as coming from individual experienceteaches us that talents are present at birth and only certain people are born with these special abilities. But scientists have studied successful musicians and found that many of them did not show any particular signs of talent at a very early age. Those who did were usually a part of a household where a parent was musical or encouraged musical activities. A child might show interest in music, and the parent then provides the musical training that helps the child become a good musician.8 Some psychologists believe that, while practice is extremely important, there is a component of intellectual ability that helps determine whether someone will be good at something like playing the piano. According to a study by psychologists David Hambrick and Elizabeth Meinz in the journal Current Directions in Psychological Science, working memory capacity, which is a core part of overall intellectual ability, can predict success in something like playing an instrument. They measured the sight-reading ability of pianists, which is the ability to successfully play a piece of music that they have never seen before. They studied two pianists who had accumulated the same number of practice hours, but had different levels of working memory capacity. The pianist with the higher working memory capacity performed better on the sight-reading task.Part A What is the best definition of the phrase working memory capacity as it is used in paragraph 8?the power of the brain to process informationthe ability of the brain to focus on a task or ideasthe length of time a useful piece of memory laststhe ability to commit ideas or routines to memory could you give me 5 chemistry equations and an explanation of them solved chemistry equations please I REALLY NEED HELP WITH THIS!!Determine the angles of a rotation A) 90 clockwise B) 90 counterclockwise C) 180 D) 270 clockwise E) 270 counterclockwise is 2 correct answers Archimedes drained the water in his tub.The amount of water left in the tub (in liters) as a function of time (in minutes) is graphed.How fast did the water drain?Choose one answer:A. 72 liters per minuteB. 74 liters per minuteC. 76 liters per minuteD. 78 liters per minute If a population consists of mainly older individuals, how would you expect the future population size to respond? find the measure of each angle.
