Using the concept of proportions, the time it takes to type 100 words is approximately 33 minutes

Let's first break down the problem and identify the given information:

The time it takes to type on a page of paper is partly constant and partly inversely proportional to the number of words.

It takes 1 hour to type 180 words.

It takes 45 minutes to type 120 words.

To solve for the time it takes to type 100 words, we can use the concept of inverse proportionality:

Let x be the time it takes to type 100 words.

We know that the time it takes to type is inversely proportional to the number of words, so we can set up the proportion:

time / number of words = constant

Using the given information, we can write two equations for the constant:

1 hour = k * 180 words

45 minutes = k * 120 words

where k is the constant of proportionality.

Solving for k in each equation:

k = 1 hour / 180 words = 1/180 hour/word

k = 45 minutes / 120 words = 3/8 minutes/word

Since we want to express the time it takes to type 100 words in minutes, we need to convert the constant to minutes/word:

1 hour = 60 minutes, so k = 1/180 * 60 = 1/3 minutes/word

45 minutes = 0.75 hours, so k = 3/8 * 60 = 22.5 minutes/word

Now we can use the constant to find the time it takes to type 100 words:

time / 100 words = constant

Plugging in the values we found for the constant:

x / 100 = 1/3 or x / 100 = 22.5

Solving for x:

x = (1/3) * 100 = 33.33 minutes (or approximately 33 minutes)

x = 22.5 * 100 = 2250 minutes (or approximately 37.5 hours)

We can discard the second solution (37.5 hours) since it doesn't make sense in the context of the problem.

Therefore, it will take approximately 33 minutes to type 100 words.

Answer:

Number of $5 notes = 18

Number of $10 notes = 15

Step-by-step explanation:

Let the number of $5 notes be 'x' and the number of $10 notes be 'y'.

      Total number of notes = 33

                  x + y = 33 -------------------(I)

       The value of $5 notes = 5*x = 5x

       The value of $10 notes = 10 *y = 10y

          Total amount = $240

          5x + 10y = 240

Divide the entire equation by 5,

             [tex]\sf \dfrac{5}{5}x+\dfrac{10}{5}y=\dfrac{240}{5}\\\\[/tex]

                x + 2y = 48 -----------------------(II)

Multiply the equation (I) by (-1) and then add to equation(I) and so the x will be eliminated, and we can find the value of 'y'.

(I)* (-1)                -x -   y  = -33

(II)                      x + 2y = 48  {Now add}

                               y     = 15

                             [tex]\boxed{\bf y = 15}[/tex]

Substitute y = 15 in equation(I)

              x + 15 = 33

                      x = 33 - 15

                      x = 18

                          [tex]\boxed{\bf x = 18}[/tex]

Number of $5 notes = 18

Number of $10 notes = 15

The standard form of the polynomial f( x ) = ( x + 4 )² - 18 is f( x ) = x² + 8 - 2.

The standard form of a polynomial is expressed as;

ax² + bx + c

To write a polynomial in its standard form, we simplify and arrange the terms in descending order.

Given the function in the question;

f( x ) = ( x + 4 )² - 18

First, simplify using FOIL Method

f( x ) = ( x + 4 )( x + 4 ) - 18

f( x ) = x( x + 4 ) + 4( x + 4 ) - 18

f( x ) = x² + 4x + 4x + 16 - 18

Add like terms

f( x ) = x² + 4x + 4x + 16 - 18

f( x ) = x² + 8 - 2

Therefore, the standard form is f( x ) = x² + 8 - 2.

The lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon. Rounding this to the nearest order of magnitude gives an answer of (b) 10⁶.

Carbon is one of the most important elements on Earth as it forms the building blocks for life and plays a crucial role in regulating the planet's climate. The carbon cycle is a complex process that involves the exchange of carbon between different reservoirs such as the atmosphere, oceans, biosphere, and lithosphere.

To compare the size of the carbon reservoirs in the biosphere and lithosphere, we can take the ratio of the two reservoirs:

Lithosphere/Biosphere = 100,005,500/560

Simplifying the expression on the right-hand side gives:

Lithosphere/Biosphere = 178,933.93

To convert this ratio to orders of magnitude, we can take the logarithm base 10 of the ratio:

log10(Lithosphere/Biosphere) = log10(178,933.93)

log10(Lithosphere/Biosphere) ≈ 5.25

Therefore, the lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon.

Christopher needs to work 20 hours during the next week to earn $368.00, assuming he is paid the same hourly wage as the previous week.

What is the proportion?

A proportion is a statement that two ratios are equal. Ratios compare two quantities by expressing the relationship between them in terms of their sizes or amounts. A proportion can be written in the form of a fraction or a ratio, and it expresses the equivalence of two ratios.

We can solve this problem using proportionality. We know that Christopher earned $404.80 for working 22 hours, which means his hourly wage can be calculated as:

hourly wage = total earnings / total hours worked = $404.80 / 22 hours = $18.40 per hour

Now we can use this hourly wage to find the number of hours Christopher needs to work to earn $368.00. Let's assume he needs to work x hours to earn $368.00. We can set up a proportion based on the hourly wage:

$18.40 per hour = $368.00 / x hours

To solve for x, we can cross-multiply:

$18.40 per hour * x hours = $368.00

Simplifying the left-hand side:

x = $368.00 / $18.40 per hour

x = 20 hours

Hence, Christopher needs to work 20 hours during the next week to earn $368.00, assuming he is paid the same hourly wage as the previous week.

The hire purchase plan, regular price $4 049, Warranty $599, interest rate 54% with36 monthly instalments​ is $216.45.

Suppose we're given that:

P_v = Present value of the loan amount

r = rate of interest (compound interest) per period of time

n = number of period of time in which loan is to be paid off

P = A fixed period payment needed to be done for paying off the loan in n number of periods.

Then, we get:

[tex]P = \dfrac{r\times P_v}{1 - (1 + r)^{-n}}[/tex]

We are given that;

Price = $4049

Warranty= $599

Interest rate=54%

Number of installments= 36

Now,

Assuming no down payment, the total cost of the purchase with the warranty is $4,049 + $599 = $4,648.

The interest rate is 54% per annum, which translates to a monthly interest rate of 54%/12 = 4.5%.

Using the formula for the monthly payment in a hire purchase plan:

Monthly payment = Total cost / Number of months / (1 - 1 / (1 + monthly interest rate)^number of months)

Plugging in the values, we get:

Monthly payment = $4,648 / 36 / (1 - 1 / (1 + 4.5%)^36)

= $4,648 / 36 / (1 - 1 / 2.7223)

= $4,648 / 36 / 0.6322

= $216.45

Therefore, the monthly payment in this hire purchase plan will be $216.45.

Option A. If the alternative hypothesis of the test had been lower-tailed instead of two-tailed, the conclusion of the test would be different.

Recall that a two-tailed test is used when the alternative hypothesis is that the population parameter is different from the null hypothesis value in any direction, while a lower-tailed test is used when the alternative hypothesis is that the population parameter is less than the null hypothesis value.

In the given scenario, if the alternative hypothesis of the test had been lower-tailed instead of two-tailed, we would have tested the following null and alternative hypotheses:

H0: Pharaoh's translation is not worse than the other software's translation.

Ha: Pharaoh's translation is better than the other software's translation.

In this case, we would have calculated the p-value for the lower tail of the sampling distribution, and compared it to the significance level alpha. If the p-value is less than alpha, we would reject the null hypothesis and conclude that Pharaoh's translation is better than the other software's translation. If the p-value is greater than alpha, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that Pharaoh's translation is better than the other software's translation.

Therefore, the product of (5v + 2)(2v - 4) is 10v^2 - 16v - 8.

Step-by-step explanation:

To find the product of (5v + 2)(2v - 4), we can use the FOIL method, which stands for First, Outer, Inner, Last. This method involves multiplying the first terms, then the outer terms, then the inner terms, and finally the last terms, and then adding the resulting terms.

Using the FOIL method, we get:

(5v + 2)(2v - 4) = (5v)(2v) + (5v)(-4) + (2)(2v) + (2)(-4)

Simplifying, we get:

10v^2 - 20v + 4v - 8

Combining like terms, we get:

10v^2 - 16v - 8

Therefore, the product of (5v + 2)(2v - 4) is 10v^2 - 16v - 8.

The surface area of the NBA basketball in terms of π is 87.96π square inches.

What is surface area ?

Surface area is the measure of the total area that the surface of an object occupies. It is a two-dimensional measure of the exposed area of an object, and is typically expressed in square units, such as square inches, square feet, or square meters.

The surface area of an object can be calculated by adding up the areas of all of its individual faces and sides. The exact method for calculating surface area depends on the shape and dimensions of the object in question. For example, the surface area of a cube can be found by multiplying the area of one face of the cube by six, while the surface area of a sphere can be calculated using the formula 4πr².

Surface area is an important concept in mathematics, and has many practical applications in fields such as architecture, engineering, and physics. For example, in architecture, surface area is used to calculate the amount of materials needed to construct a building, while in physics, surface area plays a role in determining heat transfer and other physical properties of objects.

The surface area of a sphere can be calculated using the formula:

Surface Area = 4πr²

where r is the radius of the sphere.

In this case, the radius of the NBA basketball is 4.7 inches. So, we can substitute r = 4.7 into the formula to get:

Surface Area = 4π(4.7)²

Surface Area = 4π(22.09)

Surface Area = 87.96π

Therefore, the surface area of the NBA basketball in terms of π is 87.96π square inches.

2x + 3 + 2x = 90

4. Two complementary angles are expressed as 2x and 3x.

2x + 3x= 90

5x = 90

x = 18

So, 2x = 36 and 3x = 54 degree.

5. Angles j and k are supplementary angles.

<j + <k = 180

<j + 117 = 180

<j = 63

6. Two supplementary angles are ∠ABC=105° and ∠CBD=(3x−24)°.

105 + 3x -24 = 180

3x + 81 = 180

7. Two angles are supplementary. ∠ACB=4x° and ∠BCD=6x+50°.

<ACB + <BCD = 180

4x + 6x + 50 = 180

10x = 130

x= 13

So, <ACB = 4x = 4(13)= 52.

8. For two vertical angles where ∠1=2x+26° and ∠3=3x−32°

<1 = < 3

2x + 26 = 3x -32

2x - 3x = -32 - 26

-x =-58

x= 58
