Answer:

Two ways.

(1) 4 notebooks,3 pencils, have change $12;

(2)3 notebooks, 5 pencils, have no change.

Step-by-step explanation:

set student buy x notebooks and y pencils,

x≥3,y≥3,

60x+36y≤360

if x=3, 180+36y≤360

         36y≤180

             y≤5

and y≥3, so y={3,4,5}

(1)when y=3, 60x≤360-36x3=252, x≤4.2,so x=4,

and change=360-36x3-60x4=12

(2)when y=4, 60x≤360-36x4=216, x≤3.6,so x=3,

and change=360-36x4-60x3=36, since student have to spend as much as possible of his money, $36 can buy a pencil, so this is not accepted.

(3)when y=5, 60x≤360-36x5=180, x≤3, so x=3,

and change =360-36x5-60x3=0

The student has two ways to spend his money on notebooks and pens. In one option, she can buy 4 notebooks and 3 pens and in the other option she can buy 3 notebooks and 5 pens.

To find the student's possibilities to buy pens and notebooks we must take into account his total budget of $360. Additionally, the values of the notebooks and pens that are: $60 and $36 respectively.

We must multiply the value of the notebooks by the number of notebooks that we believe the student can buy, this would be a range between 3 and 4 notebooks. Additionally, once we decide the number of notebooks we can divide the remaining money in the value of the pens to find the number of pens that the student can buy. According to the above:

If Keshawn is 1.45 meters tall. At 12 noon, he measures the length of a tree's shadow to be 15.05 meters. the height of the tree to the nearest hundredth of a meter is 2.02 meters.

To find the height of the tree, we can use the similar triangles method. Let's call the height of the tree "h".

Since Keshawn and the tree are standing in the same spot, the same light source is casting their shadows, so the ratios of their shadow lengths to their heights are equal. This means we can set up the following proportion:

1.45 / h = 15.05 / 10.8

We can solve for "h" by cross-multiplying:

h = 15.05 * 1.45 / 10.8

h = 2.02 meters

Therefore, the height of the tree to the nearest hundredth of a meter is approximately 2.02 meters.

Answer: 5.13

Step-by-step explanation:

Since the two parallel lines are cut by a transversal and m∠3 = 41°, the measure of angles m∠6 and m∠8 include the following:

m∠6 = 139°.

m∠8 = 139°.

In Mathematics, parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.

In Mathematics, the Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent:

m∠3 = m∠5 (alternate interior angles)

m∠5 + m∠6 = 180° (linear pair postulate).

41° + m∠6 = 180°.

m∠6 = 180° - 41°

m∠6 = 139°

m∠6 = m∠8 (vertical angles theorem).

m∠8 = 139°.

The value of the square root of 9 is 3.

The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, we want to find the square root of 9.

We can start by finding the perfect squares that are less than 9. The perfect squares less than 9 are 1 and 4. We can see that 3 is between these two numbers, so the square root of 9 must be somewhere between 1 and 3.

We can test whether 3 is the square root of 9 by squaring it: 3 x 3 = 9. This confirms that 3 is indeed the square root of 9.

Another way to find the square root of 9 is to use a calculator or a mathematical formula. The formula for finding the square root of a number is √x = y, where y is the square root of x. In this case, x is 9, so we have √9 = 3.

The result is 45a^3b^4+4b

The given expression is 45a^3b^4+36a^2b^5 ÷ 9a^2b^4 First, we will simplify the term 36a^2b^5 ÷ 9a^2b^4 by dividing the coefficients and subtracting the exponents of the variables.

36 ÷ 9 = 4

a^2 ÷ a^2 = a^(2-2) = a^0 = 1

b^5 ÷ b^4 = b^(5-4) = b^1 = b

So, 36a^2b^5 ÷ 9a^2b^4 = 4b

Now, we can substitute this value back into the original expression:

45a^3b^4+4b

We cannot simplify this expression any further since the terms do not have the same power of the variables.

So, the final answer is: 45a^3b^4+4b

The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.

First, find the area of the base by multiplying the length and width of the square base.

Area of base = length × width

Next, find the area of one of the triangular faces by using the formula:

Area of triangle = 0.5 × base × height

Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.

Area of triangular faces = 4 × (0.5 × base × height)

Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.

Surface area = Area of base + Area of triangular faces

= (length × width) + (4 × (0.5 × base × height))

= (length × width) + (2 × base × height)

So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.

A polygon's area is the region that it occupies. Polygons can be both regular and irregular in shape. Triangles, squares, rectangles, pentagons, hexagons, and other basic polygons are used in geometry. Each of these polygons has its own area.

A pentagon is a given polygon. The apothem is the perpendicular line drawn from the octagon's midpoint to the base of one of its sides.

The formula for determining the area of a regular polygon is expressed as

Area = a² × n × tan 180/n

Where n represents the number of sides of the polygon.

n = 5

Area = 4² × 5 × tan(180/5)

To find the area of the trapezoid ABCD, we first need to find the lengths of its parallel sides. Let's use the fact that the angles of a quadrilateral add up to 360 degrees:

Angle ABC = 124 degrees

Angle BCD = 85 degrees

Angle CDA = 96 degrees

Angle DAB = 360 - 124 - 85 - 96 = 55 degrees

Now we can use the tangent function to find the lengths of the sides:

tan(2 degrees) = (height of AB) / (distance between Anna and Benito)

(height of AB) = (distance between Anna and Benito) × tan(2 degrees)

(distance between Anna and Benito) = (713 - 690) / tan(2 degrees) ≈ 18490.3 ft

(height of AB) ≈ 429.4 ft

Similarly, we can find the height of CD:

tan(3 degrees) = (height of AD) / (distance between Anna and Deon)

(height of AD) = (distance between Anna and Deon) × tan(3 degrees)

(distance between Anna and Deon) = (725 - 690) / tan(3 degrees) ≈ 8639.5 ft

(height of AD) ≈ 459.6 ft

Now we can use the trapezoid area formula:

Area = (height of AB + height of CD) × (sum of the parallel sides) / 2

Area = (429.4 + 459.6) × ((18490.3 + 8639.5) / 2) / 5280 ≈ 128.6 acres

Since, 1 Tablespoon is equal to 15 Gram.

Therefore, 2 Tablespoon is equal to 1/8 cups or 29.5 grams.

Gram:

The gram (originally gram; SI unit symbol g) is a unit of mass in the International System of Units (SI), equal to one thousandth of a kilogram.

Originally defined in 1795 as "the absolute weight of a volume of pure water equal to one hundredth of a meter at the temperature at which ice melts." The positive temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water.

However, towards the end of the 19th century, attempts were made to make the kilogram the base unit and the gram the derived unit. In 1960, the new International System of Units defined the gram as one thousandth of a kilogram (i.e., 1 gram equals 1 × 10-3 kg. As of 2019, the kilogram is defined by the International Bureau of Weights and Measures based on the fixed value of Planck's constant (h),  

6.62607015 × 10-34 kg⋅m2⋅s-1.

According to the Question:

Convert from tablespoons to grams by multiplying the volume by 14.786765 times the density of the ingredient or material.

Using this simple formula, it can be converted to:

Grams = Tablespoons × 14.786765 × Ingredient Density

Therefore,

Grams = 02 × 14.786765

Step-by-step explanation:

The required derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).

A derivative is a two-party contract whose price or value is based on an underlying asset. Futures, options, forward contracts, and swaps are the four most popular types of derivatives. It is a financial instrument whose price and value are determined by the underlying assets.

The derivative of the natural logarithmic function is given by:

d/dx [ln(u(x))] = 1/u(x) * du/dx

So, to find the derivative of f(x) = ln(1 - x), we need to find the derivative of the inside function, which is 1 - x:

f'(x) = 1/[1 - x] * d/dx [1 - x]

= 1/[1 - x] * (-1)

= -1 / (1 - x)

So the derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).
