Answer:

he weight of 15 bags of garden soil in kilograms is 285.75 kilograms, and the volume of 15 bags in cubic yards is 1.111 cubic yards.

Step-by-step explanation:

To find the weight of 15 bags in kilograms, we can first convert the weight of one bag from pounds to kilograms and then multiply by the number of bags:

1 pound = 0.453592 kilograms

So the weight of one bag in kilograms is:

42 pounds * 0.453592 kilograms/pound = 19.05 kilograms

The weight of 15 bags in kilograms is:

15 bags * 19.05 kilograms/bag = 285.75 kilograms

To find the volume of 15 bags in cubic yards, we can first convert the volume of one bag from cubic feet to cubic yards and then multiply by the number of bags:

1 cubic yard = 27 cubic feet

So the volume of one bag in cubic yards is:

2 cubic feet / 27 cubic feet/cubic yard = 2 / 27 = 0.07407 cubic yards

The volume of 15 bags in cubic yards is:

15 bags * 0.07407 cubic yards/bag = 1.111 cubic yards

Therefore, the weight of 15 bags of garden soil in kilograms is 285.75 kilograms, and the volume of 15 bags in cubic yards is 1.111 cubic yards.

Answer:

c = -20

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

~

First, subtract 48 from both sides of the equation:

-2c + 48 = 88

-2c + 48 (-48) = 88 (-48)

-2c = 88 - 48

-2c = 40

Next, divide -2 from both sides of the equation:

(-2c)/-2 = (40)/-2

c = 40/(-2) = -20

c = -20 is your answer.

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *\((1 - (1 + r)^(-n)) / r\)

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = \(13000 * (1 - (1 + 0.10)^(-8)) / 0.10\)

Calculating this expression:

PV = \(13000 * (1 - 1.10^(-8)) / 0.10\)

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

= 69776.6

Therefore, the present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

The expected value for playing roulette if a person bet $16 on red is -$0.84.

b. The statement that best describes what this value means is option b. Over the long run, the player can expect to lose about $1.05 for each game played.

To be able to calculate the expected value, you need to multiply the probability of winning by the amount won hence it will be:

Expected value = (18/38) x  $16 - (20/38) x  $16

= -$0.84

Based on the fact that the expected value has a negative sign, it implies that, on average, the player tend to lose money over the long run.

The equations that has the solution x = all real numbers is 5(3x)+ 7x = 3x + 15 - x and 5(3x) + 7x = 3x + 10 - x,

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

A formula that expresses the connection between two expressions on each side of a sign. Typically, it has a single variable and an equal sign.

Here given equations,

5(3x) + 6x = 3x + 15 + 2x

15x + 6x = 3x + 15 + 2x

15 x + 6x - 3x -2x = 15

16 x = 15

x = 15/16

5(3x).+ 7x = 3x + 15 - x

15 x + 7x = 3x + 15 - x

15 x + 7x - 3x + x = 15

22x - 3x + x = 15

20 x = 15

x = 15/20

x = 3/4

5(3x) + 7x = 3x + 10 - x

15x + 7x - 3x + x = 10

20x = 10

x = 10/20

x = 1/2

5(3x) + 7x = x + 15 - 3x

15x +7x - x + 3x = 15

24x = 15

x = 15/24

x = 5/8

Therefore the equations that has the solution x = all real numbers are :

5(3x).+ 7x = 3x + 15 - x and 5(3x) + 7x = 3x + 10 - x .

Answer:

Step-by-step explanation:

Therefore, (f o h) (x) = 32 - 10x as an expression in terms of x.

The cube root of a number is a value that, when multiplied by itself three times, gives the original number. In other words, the cube root of a number is the value that, when cubed (raised to the power of three), gives the original number.

For example, the cube root of 27 is 3, because 3 x 3 x 3 = 27. Similarly, the cube root of 64 is 4, because 4 x 4 x 4 = 64.

The symbol for cube root is ∛. So, \(\sqrt[3]{27}\)= 3 and \(\sqrt[3]{64}\) = 4.

by the question.

To find (foh)(x), we need to substitute H(x) into f(x) in place of x:

\((f o H) (x) = f(H(x)) = 2(H(x))^2 + 8\)

Substituting H(x) into the expression for H(x), we get:

\((f o H)(x) = 2(cube root 12-5x)^2 + 8\)

Simplifying:

\((f o H)(x) = 2(12-5x) + 8\)

\((f o H) (x) = 32 - 10x\)

Based on the trapezoid midsegment theorem, we have:

1. EF = 1/2(AB + CD)

2. x = 16/3

3. AB = 51 units.

The trapezoid midsegment theorem states relationship between the length of the midsegment and its bases as:

Length of the midsegment = 1/2(sum of the length of the trapezoid bases).

1. Given the following:

EF = 5x + 13 (midsegment of the trapezoid)

AB = 9x + 3 (one of its bases)

CD = 4x + 7 (one of its bases)

According to the trapezoid midsegment theorem, the relationship between the length of the midsegment and the bases of the trapezoid would be stated as:

EF = 1/2(AB + CD)

Substitute

5x + 13 = 1/2(9x + 3 + 4x + 7)

5x + 13 = 1/2(13x + 10)

2. 5x + 13 = 1/2(13x + 10) (relationship described)

Solve for x

2(5x + 13) = 13x + 10

10x + 26 = 13x + 10

Combine like terms

10x - 13x = -26 + 10

-3x = -16

Divide both sides by -3

-3x/-3 = -16/-3

x = 16/3

3. AB = 9x + 3

The zeroes are -1, 2, and 4. Factored: (x+1)(x-4)(x-2)=0

Step-by-step explanation:

Kira has $19, Boris has $75, and Deshuan has $25.

We will denote as follows:

From information, we can set up equations:

B = 3D (Boris has 3 times what Deshuan has)

D = K + 6 (Deshuan has $6 more than Kira)

K + B + D = 119 (The total amount of money they have is $119)

Substituting equation 2 into equation 1, we have:

B = 3(K + 6)

Substituting equations 1 and 2 into equation 3:

K + 3(K + 6) + (K + 6) = 119

K + 3K + 18 + K + 6 = 119

5K + 24 = 119

5K = 119 - 24

5K = 95

K = 95 / 5

K = 19

Using equation 2, we can find D:

D = K + 6

D = 19 + 6

D = 25

Using equation 1, we can find B:

B = 3D

B = 3 * 25

B = 75.

The differential equation that can represent all circles in the xy plane is given as follows:

\(\frac{dy}{dx} = -\frac{x - h}{\sqrt{r^2 - (x - h)^2}}\)

The equation of a circle of center (h,k) and radius r is given as follows:

(x - h)² + (y - k)² = r².

The equation can be arranged to isolate the variable y as follows:

(y - k)² = r² - (x - h)²

y - k = square root (r² - (x - h)²)

y = square root (r² - (x - h)²) + k

To obtain the differential equation, then this equation must be differentiated towards variable x as follows:

\(\frac{dy}{dx} = \frac{d}{dx}(\sqrt{r^2 - (x - h)^2} + k)\)

Applying the chain rule, along with the derivative for the square root, we have that:

\(\frac{d}{dx}(\sqrt{r^2 - (x - h)^2} + k) = -\frac{x - h}{\sqrt{r^2 - (x - h)^2}}\)
