A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 45 pounds each, and the small boxes weigh 25 pounds each. There are 120 boxes in all. If the truck is carrying a total of 4300 pounds in boxes, how many of each type of box is it carrying?

Answers

Answer 1

Answer:

50(115-y) + 25y = 4125             [from eq2]

    5750 - 50y  + 25y = 4125           [distribute]

    5750 - 25y = 4125

     -25y = -1625

        y = 65             [divide both sides by (-25)]

There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

 x = 115 - y

 x = 115 - 65

 x = 50

 There are 50 large boxes.

Answer 2

The required number of boxes that the truck contain is 55 small boxes and 65 large boxes.  

Given that, the large boxes weigh 45 pounds each, and the small boxes weigh 25 pounds each. There are 120 boxes in all, the truck is carrying a total of 4300 pounds.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Let the number of large boxes will be l and the number of small boxed be s,

According to the question,
l + s = 120
l = 120 - s - - - - - (2)
Again,
45l + 25s = 4300
put l in the above equation,
45[120 - s] + 25s = 4300
5400 - 45s + 25s = 4300
20s = 1100
s = 1100/20
s = 55
Now,
l = 120 - 55
l = 65

Thus, the required number of boxes that the truck contain is 55 small boxes and 65 large boxes.

a scientist has 400ml of a 8% solution. how much water needs to be added to lower it to a 2% solution?

Answers

1200 ml  of water needs to be added to lower it to a 2% solution.

Step-by-step explanation:

Given that,

A scientist has 400ml of a 8% solution.

you need to find how water is required to lower the 400 ml to 2% solution.

Let 'x' be the amount of water added to lower it 2% solution.

The formula is given by,

volume of the liquid × % of solution = volume of the new liquid × new %

This can be denoted in chemical relationship ⇒ c₁v₁=c₂v₂ where c is concentration and v is volume .

Now, to find the total volume of new liquid in ml :

400 ml = v₁

0.08= c₁  

0.02=c₂

v₂=?

400 × 0.08 =v₂ × 0.02

v₂=1600 ml

To find the x value :

Amount to be added = volume of new liquid - volume of liquid before.

⇒ x =1600-400

⇒ x =1200 ml

∴ 1200 ml of water needs to be added to lower it to a 2% solution.

Mr Tan invested $5000 in an endowment fund for
5 years. The fund pays an interest compounded
yearly. At the end of 5 years, he received a total of
$5800. Find the interest rate.​

Answers

Answer:

Compound Interest Formula Solved For Rate:

log (1 + rate) = {log(total) -log(Principal)} ÷ Years

log (1 + rate) = {log(5,800) -log(5,000)} ÷ 5

log (1 + rate) = [3.7634279936 -3.6989700043] / 5

log (1 + rate) = 0.0644579893  / 5

log (1 + rate) = 0.0128915979

Then we raise 10 to the power of 0.0128915979  which equals

1.0301289629  = 1 + rate

Therefore, rate = .0301289629  and we multiply by 100 to make a percentage:

https://1728.org/compint.htm

Step-by-step explanation:

Final answer:

Using the compound interest formula and the provided values, the interest rate for Mr Tan's investment is calculated to be approximately 3.02%.

Explanation:

The subject problem belongs to the topic of Compound Interest in mathematics. The formula used for compound interest is A = P (1 + r/n)^(nt), where A represents the total amount received, P represents the principal (initial investment amount), r represents the rate of interest, n represents the number of times interest is compounded per time period, and t represents the time period.

In this problem, Mr Tan's initial investment, P, is $5000. The total amount, A, he received after 5 years is $5800. The interest is compounded annually meaning that n is 1. We rearrange the compound interest formula to solve for the interest rate: r = [(A/P)^(1/nt) - 1]n .

Using Mr Tan's values, the calculation becomes: r = [(5800/5000)^(1/5) - 1]*1. Thus, the interest rate is approximately 0.0302 or 3.02%.

Stocking company a has decreased 25% since last year in stock and Company B has decreased 22%. What was the total percentage decrease in the investor stock account round your answer to the nearest 10

Answers

Answer: 24.5%

Step-by-step explanation:

Last year her stock in company A was worth $4600. If her Stock in company A has decreased by 25% since last year in stock, then the amount by which it decreased is

25/100 × 4600 = $1150

The present worth is

4600 - 1150 = $3450

Also, her stock in company B was worth $1000. If her Stock in company B has decreased by 22% since last year in stock, then the amount by which it decreased is

22/100 × 1000 = $220

The present worth is

1000 - 220 = $780

The total worth of both stocks last year was

4600 + 1000 = $5600

The total worth of both stocks this year was

3450 + 780 = $4230

The amount by which it decreased is

5600 - 4230 = 1370

the total percentage decrease in the investor stock account is

Step-by-step explanation:

If you graph it out, you'll realize it makes a line that cuts the y-intercept at -76, thus the last value. The slope also has a gradient of 6, thus the coeffecient of x.

Final answer:

The slope of the line through the points given is 6, calculated using the slope formula with the rise over run between the two points.

Explanation:

The slope of a line is calculated by finding the ratio of the vertical change (the rise) to the horizontal change (the run) between two points on the line. Using the coordinates provided (12, -4) and (15, 14), we can apply the slope formula slope (m) = (y_2 - y_1) / (x_2 - x_1). Plugging in the values gives us (14 - (-4)) / (15 - 12) = 18 / 3 = 6. Therefore, the slope of the line that contains these points is 6.

Answers

Final answer:

Translations of functions involve adjusting the graph horizontally by adding or subtracting values within the function's argument, and vertically by adding or subtracting values directly to the function. For the given functions, respective translations have resulted in g(x) expressions that have been adjusted according to these rules.

Explanation:

To answer the student's mathematics questions about translations of functions, we will apply the concepts learned from algebra to transform each given function accordingly.

Translation 7 units up of f(x) = x results in g(x) = x + 7.For the translation 5 units left of f(x) = x2, we use g(x) = (x + 5)2.The translation 3 units right and 4 units up of f(x) = x2 gives us g(x) = (x - 3)2 + 4.Translation 1 unit left and 5 units down of f(x) = |x| leads to g(x) = |x + 1| - 5.

In these function transformations, we've made use of horizontal and vertical translations, where adding or subtracting values within the function argument adjusts the graph horizontally, and adding or subtracting values outside the function adjusts it vertically.

Explain:
We need to count the number of ways that we can make a license plate number that has 3 digits followed by 3 letters.

For a digit, there are 10 possible choices (0,1,2,3,...9).
For a letter there are 26 choices (a,b,c,...,z).

The license plate number has six slots.
The first three slots will have three digits. There are 10*10*10 = 1000 ways to make the first three digits.

The last three slots will have three letters. There are 26*26*26=17576 ways to make the last three letters.

Combine these by multiplying. So there are 17576000 license plates.

The total number of possible New York license plates is 17,576,000.

The number of different license plates possible for a standard configuration in New York, where a license plate is composed of 3 digits followed by 3 letters, can be determined through combinatorial math.

Step-by-Step Solution:

There are 10 possible digits (0-9) and 26 possible letters (A-Z).Since repetitions are allowed, we calculate the total number of combinations for digits and letters separately.The number of ways to choose 3 digits is 10 3 = 10 × 10 × 10 = 1000.The number of ways to choose 3 letters is 26 3 = 26 × 26 × 26 = 17576.Multiplying these two results together gives the total number of possible license plates: 1000 × 17576 = 17576000.

James has an ice cube tray that makes ice in the shape of spheres rather than cubes. Each sphere of ice has a radius of 2 cm. One tray makes 6 spheres.What is the total volume of ice the tray can make at one time?

Total volume of the tray James have = 201.06 cm^3

Step-by-step explanation:

Given:

Radius of the spherical ice cube = 2 cm

No. of spheres in the ice cube = 6

We have to find the total volume of the ice tray that can make at one time.

Let the total volume be "V".

Formula to be used:

Volume of sphere =  [tex]\frac{4\pi r^3 }{3}[/tex]  cubic unit.

Total volume = [tex]n\times \frac{4\pi r^3 }{3}[/tex] cubic unit.

So,

Total volume of the ice tray (V) :

⇒ [tex]V=n\times \frac{4\pi r^3 }{3}[/tex]

⇒ Plugging n = 6 and r = 2

⇒ [tex]V=6\times \frac{4\pi (2)^3 }{3}[/tex]

⇒ [tex]V=6\times \frac{4\pi (8) }{3}[/tex]

⇒ [tex]V=6\times \frac{32\pi }{3}[/tex]

⇒ [tex]V=\frac{32\times 6\pi }{3}[/tex]

⇒ [tex]V=32\times 2\pi[/tex]

⇒ [tex]V=201.06\ cm^3[/tex]

So,

The total volume of ice the tray can make at one time = 201.06 cm^3

In a city school, 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair. What is the probability (rounded to the nearest whole percent) that a randomly selected student has dark hair, given that the student has blue eyes

Answers

Answer:

The probability that a randomly selected student has dark hair, given that the student has blue eyes is 43%.

Step-by-step explanation:

Conditional probability:

Let A and B any two events connected to a given random experiment E. The conditional probability of the event A on the hypothesis that the event B has occurred, denoted by P(A|B), is defined as

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

Given that,

In a city school, 70% of students have blue eyes, 45% have dark eyes and 30% have blue eyes and dark hair.

A= students have blue eyes

B= Students have dark hair.

P(A)= 70% [tex]=\frac{70}{100}[/tex] [tex]=\frac7{10}[/tex]

P(B)=45% [tex]=\frac{45}{100}[/tex] [tex]=\frac9{20}[/tex]

P(A∩B)=30%[tex]=\frac{30}{100}[/tex] [tex]=\frac3{10}[/tex]

∴P(B|A)

[tex]=\frac{P(A\cap B)}{P(A)}[/tex]

[tex]=\frac{0.3}{0.7}[/tex]

[tex]=\frac37[/tex]

=0.429

=0.429×100 %

≈43%

The probability that a randomly selected student has dark hair, given that the student has blue eyes is 43%.

A manufacturer of cell phone screens is concerned because 12 percent of the screens manufactured using a previous process were rejected at the final inspection and could not be sold. A new process is introduced that is intended to reduce the proportion of rejected screens. After the process has been in place for several months a random sample of 100 screens is selected and inspection. Of the 100 screens 6 are rejected. What are the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected

Answers

Final answer:

In hypothesis testing for this scenario, the null hypothesis (H-0) is that the proportion of rejected screens remains 12 percent (H-0: p = 0.12). The alternative hypothesis (Ha) is that the proportion of rejected screens is less than 12 percent (Ha: p < 0.12). A sample is taken and a significance test (such as a z-test for proportion) is conducted to decide if the null hypothesis can be rejected.

Explanation:

The question is looking for you to conduct a hypothesis test to investigate whether a new process in manufacturing cell phone screens has led to a reduced proportion of rejected screens. When conducting such a hypothesis test, you'll need to consider a null hypothesis and an alternative hypothesis.

The null hypothesis (H-0) is often the initial claim about a population proportion. In this case, the null hypothesis would be that 12 percent of the screens (0.12) are still being rejected: H-0: p = 0.12.

The alternative hypothesis (Ha) is what you might believe to be true if the null hypothesis is proven to be incorrect. Here, the alternative hypothesis would be that less than 12 percent of screens are being rejected with the new process: Ha: p < 0.12.

To clarify, if the new process is effective, a lower proportion of screens should be rejected. Thus, the hypotheses to be tested are:

H-0: p = 0.12Ha: p < 0.12

Lastly, after selecting the sample, compute the sample proportion. Here a total sample size of 100 screens with only 6 being rejected means the sample proportion (p) = 6/100 = 0.06.

From here, you would proceed to conduct a significance test (possibly a z test for proportion) and determine a p-value to make a decision regarding the null hypothesis.

- then double the answer (or times it  by 2):

1) 30 times 20 = 600

30 times 5= 150

20 times 5 =100

2) Add them:

600+150+100 = 850

then times 850 by 2

850 times 2 = 1700

Hope that helped :)

Answer:

Guys for this one the 30, 20, 5 is 1700

what is the area of a 3in by 3in square

Answers

Final answer:

The area of a 3in by 3in square is calculated by squaring the side length. The area is 9 square inches.

Explanation:

The area of a 3in by 3in square can be calculated by multiplying the length of one side by the length of another side since the sides are equal in a square. In this case, both sides measure 3 inches.

The formula for the area of a square is:

Area = side × side

Applying the formula for our 3in by 3in square:

Area = 3in × 3in = 9 square inches

This straightforward calculation represents how the surface area of a square object changes when the sides of the square are altered. When the sides of a square are scaled down by a fraction, the area changes by the square of that fraction (e.g., scaling down by 3/4 leads to an area that is 9/16 of the original).

Answer:

ength (l) : (10-2*5/3) = 20/3 width(w): (10 - 2*5/3) = 20/3 height(h): 5/3

Step-by-step explanation:

Let x is the side of identical squares

By cutting out identical squares from each corner and bending up the resulting flaps, the dimension are:

length (l) : (10-2x)width(w): (10-2x)height(h): x

The volume will be:

V = (10-2x) (10-2x) x

<=> V = (10x-2[tex]x^{2}[/tex]) (10-2x)

<=> V = 100x -20[tex]x^{2}[/tex] - 20[tex]x^{2}[/tex] + 4[tex]x^{3}[/tex]

<=> V = 4[tex]x^{3}[/tex]  - 40[tex]x^{2}[/tex] + 100x

To determine the dimensions of the largest box that can be made, we need to use the derivative and and set it to zero for the maximum volume

dV/dx = 12[tex]x^{2}[/tex] -80x + 100

<=>  12[tex]x^{2}[/tex] -80x + 100 =0

<=> x = 5 or x= 5/3  

You know 'x' cannot be 5 , because if  we cut 5 inch squares out of the original square, the length and the width will be 0. So we take x = 5/3

=>

length (l) : (10-2*5/3) = 20/3 width(w): (10 - 2*5/3) = 20/3 height(h): 5/3
Final answer:

To determine the dimensions of the largest box that can be made from a tin sheet, we need to find the side length of the square that will be cut out from each corner of the tin sheet. The dimensions of the largest box that can be made are approximately 6.67 inches by 6.67 inches by 1.67 inches.

Explanation:

To determine the dimensions of the largest box that can be made from a tin sheet, we need to find the side length of the square that will be cut out from each corner of the tin sheet. Let's assume the side length of the square to be x inches. The length and width of the resulting box will be 10 - 2x inches and 10 - 2x inches, respectively. The height of the box will be x inches. To find the dimensions of the largest box, we need to find the value of x that maximizes the volume of the box.

The volume of the box is given by V = (10 - 2x)(10 - 2x)(x). We can write this as V = 4x^3 - 40x^2 + 100x. To find the value of x that maximizes the volume, we can take the derivative of V with respect to x and set it equal to 0. Differentiating V, we get dV/dx = 12x^2 - 80x + 100. Setting this equal to 0 and solving for x, we find x = 1.67 inches (rounded to two decimal places). Therefore, the dimensions of the largest box that can be made are approximately 6.67 inches by 6.67 inches by 1.67 inches.
