Answer:

The total length of the 30 pencils in centimeters is:

30 x 16 = 480 cm

To convert centimeters to meters, we divide by 100:

480 cm / 100 = 4.8 m

Therefore, the combined length of the 30 pencils is 4.8 meters.

Step-by-step explanation:

a. Slope of RS = [tex]-\frac{7}{5}[/tex] and slope of adjacent to RS =  [tex]-\frac{5}{7}[/tex]

b. Length of RS  = [tex]\sqrt{74}[/tex] and Length of adjacent to RS = [tex]\sqrt{74}[/tex]

c. The parallelogram PQRS is Rhombus.

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. As a result, a parallelogram's opposite sides are parallel and congruent in length, and its opposite angles are similarly congruent.

[tex]Slope = \frac{(y_{2} -y_{1})}{(x_{2} -x_{1})}[/tex]

a. for the points R (-6, 6) and S (-1, -1)

Slope of RS = [tex]\frac{-1 - (+6)}{-1 - (-6)}[/tex] = [tex]-\frac{7}{5}[/tex]

Slope of RS = [tex]-\frac{7}{5}[/tex]

Slope of adjacent side (RQ, SP) to RS = [tex]\frac{6-1}{-6-1}[/tex] = [tex]\frac{5}{-7}[/tex]

Slope of adjacent to RS =  [tex]-\frac{5}{7}[/tex]

b. Length of a line = [tex]\sqrt{({x_{2}-x_{1})^{2} } + ({y_{2}-y_{1})^{2}}[/tex]

points R (-6, 6) and S (-1, -1)

Length of RS = [tex]\sqrt{({-1- (-6))^{2} } + ({-1-6})^{2}}[/tex] = [tex]\sqrt{74}[/tex]

Length of RS  = [tex]\sqrt{74}[/tex]

Length of adjacent to RS = [tex]\sqrt{({-6- 1))^{2} } + ({6-1})^{2}}[/tex] = [tex]\sqrt{74}[/tex]

Length of adjacent to RS = [tex]\sqrt{74}[/tex]

c. All sides are equal

PQ=QR=RS=SP=√74

So, diagonal PR = [tex]\sqrt{({-6- 6))^{2} } + ({-6-6})^{2}}[/tex] = [tex]12\sqrt{2}[/tex]

and  diagonal QS = = [tex]\sqrt{({-1- 1))^{2} } + ({-1-1})^{2}}[/tex] = [tex]2\sqrt{2}[/tex]

Diagonals are unequal then parallelogram PQRS is Rhombus.

Answer:-7/8m+3/10

Step-by-step explanation:

Answer:

1a) Increment in price = 5500 - 4500 = 1000 Naira

1b) Percentage increase in price = (increment in price / old price) x 100%

= (1000 / 4500) x 100%

= 22.22%

2) Marked price = selling price / (1 - discount percentage)

= 3000 / (1 - 0.1)

= 3333.33 Naira

3) Total cost of 30 crates of eggs = 30 x 30 = 900 Naira

Commission = (4/100) x 900

= 36 Naira

4) Commission = (7/100) x 49000

= 3430 Naira

5) Discount = marked price - selling price

= 44.48 - 39.28

= 5.20 Naira

6) Discount = (245 - 225) / 245 x 100%

= 8.16%

7) Commission = (3/100) x 33

= 0.99 Naira

8) New salary = old salary + 5% of old salary

= 250 + (5/100) x 250

= 262.50 Naira

9) Marketed price = selling price / (1 - discount percentage)

= 55 / (1 - 0.05)

= 57.89 Naira

10) Marketed price = selling price + discount

= 845 + 55

= 900 Naira

Percentage discount = (discount / marked price) x 100%

Step-by-step explanation:

The terms in the numerator and simplify the fraction, giving us: -2x² - 1/(2x + 1)

A numerator is the part of a fraction that is above the line and indicates how many parts of a whole are being considered. It is the number that is being divided.

The first step in solving this problem is to factor out the numerator. Using the distributive property, we can rewrite the numerator as:

(-3x² + 6x³ - 4 - x) = (-3x² + 6x³ - 4) - x

Now, we can factor out -3x² from the first two terms, giving us:

(-3x² + 6x³ - 4) - x = -3x²(1 + 2x - 4/3x²) - x

We can now divide the numerator and denominator by the common factor of -3x², giving us:

(-1 - 2x + 4/3x²) - (x/(-3x²)) ÷ (2x + 1)

By dividing the numerator and denominator by -3x², we can now cancel out the -3x² terms, leaving us with:

(-1 - 2x + 4/3x²) - (1/3) ÷ (2x + 1)

The next step is to simplify the fraction. To do this, we must multiply the numerator and denominator by the reciprocal of the denominator. In this case, the reciprocal is -1/(2x + 1) giving us:

[(-1 - 2x + 4/3x²) - (1/3)] × (-1/(2x + 1))

Simplifying the numerator yields:

(2x + 1 - 4/3x² + 1/3) × (-1/(2x + 1))

Finally, we can combine the terms in the numerator and simplify the fraction, giving us: -2x² - 1/(2x + 1).

Answer:

2/(1/4) = 8 1/4th gallons to fill the container and 1/8 * x = 8/8 (x=8) times you can fill the tank with 1/4th gallon

Step-by-step explanation:

First let's answer the first part of the question: what fraction of the container is filled?

If there is 1/4 a gallon of water in the container which holds 2 gallons, we can show this by adding 0/4 to 1/4 to get 1/8 as the fraction of the container filled. (Or just double the denominator for both gallons instead of 1)

To represent this with a multiplication equation, we will take the holding of the container which is 2 gallons

1/8 times x = how many times you can fill the container with 1/4 gallon of water (which is 8 total)

and then our division which is

2 divided by 1/4 = how many shares of water can fit in the container

Therefore, the general solution for the differential equation dy/dx cosx=ysinx+sin113x is y = log |sin(x) / sin(113x)| + C, where C is an arbitrary constant.

A differential equation explains the unknown derivative or derivatives of a function. Example: Think about the equation. The equation d y d x = x sin represents the derivative of an unknown function.

We can solve this differential equation by using separation of variables.

First, we'll rearrange the equation to isolate the y term on one side:

cos x = y sin x + sin 113x

cos x - sin 113x = y sin x

y = (cos x - sin 113x) / sin x

Now we can integrate both sides with respect to x:

∫dy = ∫(cos x - sin 113x) / sin x dx

Using integration by parts, we can integrate the second term on the right side:

∫dy = ∫cos x / sin x dx - ∫sin 113x / sin x dx

The first term on the right side can be integrated using substitution:

u = sin x, du/dx = cos x dx

∫cos x / sin x dx = ∫du/u = log |u| + C1 = log |sin x| + C1

The second term on the right side can be rewritten as:

∫sin 113x / sin x dx = - ∫sin 113x / sin 113x cos x dx

= - ∫csc x cos 113x dx

Using substitution again:

u = sin 113x, du/dx = 113 cos 113x dx

∫csc x cos 113x dx = - ∫du/u = - log |sin 113x| + C2

y = log |sin x| - log |sin 113x| + C

Simplifying:

y = log |sin(x) / sin(113x)| + C

Therefore, the general solution for the differential equation dy/dx cosx=ysinx+sin113x is y = log |sin(x) / sin(113x)| + C, where C is an arbitrary constant.

Answer: a) To find the number of working days on which under 18,000 bottles are filled, we need to calculate the z-score for this value:

z = (18,000 - 20,000) / 2000 = -1

Using a standard normal distribution table or calculator, we find that the probability of a value being less than -1 standard deviation is approximately 0.1587. Therefore, the approximate number of working days on which under 18,000 bottles are filled is:

0.1587 x 260 ≈ 41

b) To find the number of working days on which over 16,000 bottles are filled, we need to calculate the z-score for this value:

z = (16,000 - 20,000) / 2000 = -2

Using a standard normal distribution table or calculator, we find that the probability of a value being less than -2 standard deviations is approximately 0.0228. Therefore, the approximate number of working days on which over 16,000 bottles are filled is:

0.0228 x 260 ≈ 6

c) To find the number of working days on which between 18,000 and 24,000 bottles are filled, we need to calculate the z-scores for these values:

z1 = (18,000 - 20,000) / 2000 = -1

z2 = (24,000 - 20,000) / 2000 = 2

Using a standard normal distribution table or calculator, we find that the probability of a value being less than -1 standard deviation is approximately 0.1587, and the probability of a value being less than 2 standard deviations is approximately 0.9772. Therefore, the approximate number of working days on which between 18,000 and 24,000 bottles are filled is:

(0.9772 - 0.1587) x 260 ≈ 236

Answer:

If 1, -5, and -1/2 are zeros of a polynomial function, then the factors of the polynomial are:

(x - 1), (x + 5), and (2x + 1)

To find the polynomial function, we multiply these factors together and simplify:

(x - 1)(x + 5)(2x + 1)

= (x^2 + 4x - 5)(2x + 1)

= 2x^3 + 9x^2 - 6x - 5

Therefore, the polynomial function of the least degree with integral coefficients that has the zeros 1, -5, and -1/2 is:

f(x) = 2x^3 + 9x^2 - 6x - 5

From the quadratic equation, we found the new dimensions:

Length =  14.85 feet

Width = 18.85 feet.

What is a quadratic equation?

The polynomial equations of degree two in one variable of type

f(x) = ax² + bx + c = 0 and with a, b, c, ∈ R and a ≠ 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" is for the absolute term of

f (x).

The current dimensions of the farm are 10 feet by 14 feet.

Length l = 10 feet

Width w = 14 feet

Area a = l * w = 10 * 14 = 140 sq. feet.

Now the new area is doubled.

A = 2a = 2 * 140 = 280 sq.feet

The new dimensions are:

L = l + x = 10 + x

W = w + x = 14 +x

A = (10+x)(14+x)

280 = 140 + 10x + 14x + x²

x² + 24x - 140 = 0

This is a quadratic equation.

Solving the equation, we get

x = 4.85, -28.85

Neglecting the negative value, we get the value of x as 4.85.

Therefore from the quadratic equation, we found the new dimensions:

L = 10 + 4.85 = 14.85 feet

W = 14 + x = 14 + 4.85 = 18.85 feet.

Subtraction is a mathematical operation that involves finding the difference between two numbers or quantities. It is the inverse of addition, which means that it is the opposite process of adding numbers.

In subtraction, a number or quantity (called the subtrahend) is subtracted from another number or quantity (called the minuend), resulting in the difference. The symbol used for subtraction is "-" and the resulting value is called the remainder or difference.

Katie had 12 gallons of gas.

She used 2 1/2 gallons of gas each hour.

Now, She drove 2 hours.

So, gallon of gas use for 2 hours = 2 × 2 1/2
