Phillip's net loss after adding 15 pencils to his collection and giving away 30 pencils is 15 pencils.

A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.

To calculate Phillip's net gain or loss, we need to subtract the number of pencils he gave away from the number he added to his collection.

Let's use the variable "x" to represent the number of pencils Phillip had before he added 15 pencils to his collection.

Then the expression for the total number of pencils Phillip has after giving away 30 pencils would be:

x + 15 - 30

Simplifying this expression, we get:

x - 15

Therefore, x - 15 is the required expression.

The target is 4125 feet away from the bullet.

To find the distance between the target and the bullet, we need to use the formula distance = speed × time. We have two distances to find: the distance the bullet travels and the distance the sound travels. Let's call the distance between the target and the bullet d.

The distance the bullet travels is given by:
d = 3300 × t

The distance the sound travels is given by:
d = 1100 × (t - 2.5)

Since the two distances are equal, we can set the two equations equal to each other and solve for t:

3300 × t = 1100 × (t - 2.5)
3300t = 1100t - 2750
2200t = 2750
t = 1.25

Now that we have the time, we can plug it back into one of the equations to find the distance:

d = 3300 × 1.25
d = 4125 feet

So the target is 4125 feet away from the bullet.

The concrete cost for the pillar was $37,879.52.

Velocity is a quantity that indicates how quickly and in which direction a point is moving. A point always moves in a direction that is tangent to its path; for example, a circular path's direction at any instant is perpendicular to a line connecting the point to the circle's centre (a radius). The magnitude of the velocity (or speed) is the rate at which the point moves along its path in time.

If a point moves a certain distance along its path in a given time interval, its average speed is equal to the distance moved divided by the time taken. A train travelling 100 kilometres in two hours, for example, has an average speed of 50 kilometres per hour.

The cylinder's radius is equal to its diameter divided in half, or 12/2, or 6 metres.

The cylinder's volume is determined by:

[tex]V = pi * r^2 * h[/tex]

[tex]V = 3.14 * 6^2 * 4[/tex]

V equals 452,16 cubic metres

The price of the concrete is $82 per cubic metre, making the overall price:

$82 * 452.16 = $37,879.52

Hence, the pillar's concrete expense came to $37,879.52.

As a result, after 14 years, the investment that was compounded interest irregularly will be valued $961.54 more than the one that was compounded yearly.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

We must apply the compound interest calculation in order to compare the values of the investment compounded annually with the investment compounded periodically:

[tex]A = P(1 + r/n)^(nt) (nt)[/tex]

where:

A is the total sum.

The principal is P. (the initial amount)

n is the number of times the interest is compounded each year, and r is the yearly interest rate (expressed as a decimal).

The number of years is t.

We have the following for the yearly compounded investment:

[tex]A = 9000(1 + 0.06/1)^(1*14) = $20,207.97[/tex]

Periodically compounded investment results in:

[tex]A = 9000(1 + 0.06/12)^(12*14) = $21,168.51[/tex]

To find out how many of each product Derrick can buy, we can use algebra. Let's call the number of headphones x and the number of cell phone cases y. We can set up an equation to represent the situation:

26x + 14y = 150

Now we can solve for one of the variables in terms of the other. Let's solve for y:

14y = 150 - 26x

y = (150 - 26x)/14

Now we can plug in different values for x and see what values of y will result in a total cost of at least $150. For example, if x = 1, then y = (150 - 26)/14 = 8.86. This means that Derrick could buy 1 pair of headphones and 8 cell phone cases for a total cost of $150.

Similarly, if x = 2, then y = (150 - 52)/14 = 7. This means that Derrick could buy 2 pairs of headphones and 7 cell phone cases for a total cost of $150.

We can continue plugging in different values for x until we find a combination of products that will cost at least $150. Alternatively, we could use a graphing calculator or an online graphing tool to graph the equation and find the intersection points with the line y = 150. These intersection points will represent the combinations of products that will cost at least $150.

To find the missing dimension (length), we can use the formula for the volume of a prism:

Volume = Base Area x Height

We know that the volume of the prism is 60 in³ and the height is 4 in. We also know that the base of the prism is a rectangle with a width of 2.5 in.

Base Area = Length x Width

We can rearrange the formula for volume to solve for the missing dimension:

Length = Volume / (Base Area x Height)

Base Area = Width x Length

Plugging in the given values, we get:

Base Area = 2.5 in x Length

Base Area x Height = 10 in²

Length = 60 in³ / (10 in² x 4 in)

Length = 1.5 in

Therefore, the missing dimension (length) of the prism is 1.5 inches.

For the logarithmic function y = log (5x+6), the domain is (-6/5, [infinity]).

The domain of a logarithmic function is the set of all values for which the function is defined. In the case of y = log(5x+6), the function is only defined for values of x that make the expression inside the logarithm, 5x+6, greater than zero. This is because the logarithm of a negative number or zero is not defined.

To find the domain analytically, we need to solve the inequality 5x+6 > 0 for x:

5x+6 > 0

5x > -6

x > -6/5

This means that the domain of the function is all values of x greater than -6/5. In interval notation, this can be written as (-6/5, infinity).

So the domain of the logarithmic function y = log(5x+6) is (-6/5, infinity).

3) Exact surface area of the cylinder with radius 1 and three-fourths centimeters and height 3 and one-fourth centimeters is 35 and seven-eighths times pi square centimeters.

4) The area of icing needed for one red velvet cake with a radius of 13 centimeters and a height of 15 centimeters is approximately 459 square centimeters.

What is the surface area of the cylinder?

The surface area of a cylinder is the total area of all its curved and flat surfaces. It is given by the formula:

Surface Area = 2πr² + 2πrh

To answer these questions, we need to use the formula for the surface area of a cylinder:

Surface Area = 2πr² + 2πrh

where r is the radius of the circular base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi.

We are given that the container was covered in plastic wrap during manufacturing. We are not given the dimensions of the container, but we can assume it is a cylinder. Therefore, we need to calculate the surface area of the cylinder. We are not given the values of r and h, so we cannot calculate the surface area directly. Therefore, we cannot determine the answer to this question.

We are given the net of a cylinder with a labeled radius of 4 inches and a labeled height of 3 inches. To find the surface area of the cylinder, we need to use the formula:

Surface Area = 2πr² + 2πrh

Substituting r = 4 and h = 3, and using π ≈ 3.14, we get:

Surface Area = 2(3.14)(4²) + 2(3.14)(4)(3) = 100.48 in²

Therefore, the surface area of the cylinder is 100.48 in².

We are given a cylinder with a labeled radius of 1 and three-fourths centimeters and a labeled height of 3 and one-fourth centimeters. To find the surface area of the cylinder, we need to use the formula:

Surface Area = 2πr² + 2πrh

Substituting r = 1.75 and h = 3.25, we get:

Surface Area = 2(3.14)(1.75²) + 2(3.14)(1.75)(3.25) = 35.875π cm²

Therefore, the exact surface area of the cylinder in terms of π is 35 and seven-eighths times pi square centimeters.

We are given a red velvet cake with a radius of 13 centimeters and a height of 15 centimeters. We need to find the area of the circular top of the cake, which is the same as the surface area of a cylinder with radius 13 and height 0. We can use the formula:

Surface Area = 2πr² + 2πrh

Substituting r = 13 and h = 0, we get:

Surface Area = 2(3.14)(13²) + 2(3.14)(13)(0) = 1061.76 cm²

We need to subtract this from the surface area of the whole cylinder (the cake) to find the area of the icing. Using the formula again with r = 13 and h = 15, we get:

Surface Area = 2(3.14)(13²) + 2(3.14)(13)(15) = 1520.6 cm²

Therefore, the area of icing needed for one cake is:

1520.6 - 1061.76 = 458.84 cm²

Rounding this to the nearest square centimeter, we get:

459 cm²

Therefore, approximately 459 square centimeters of icing is needed for one cake.

Hence,

1) Cannot be determined.

2) Surface area of the cylinder with radius 4 inches and height 3 inches is 100.48 square inches.

3) Exact surface area of the cylinder with radius 1 and three-fourths centimeters and height 3 and one-fourth centimeters is 35 and seven-eighths times pi square centimeters.

The product of ((2)/(3)x+(4)/(3)) and (2x+(5)/(6)) as a trinomial in simplest form is (4/3)x^2 + (13/9)x + (10/9).

To express the product of ((2)/(3)x+(4)/(3)) and (2x+(5)/(6)) as a trinomial in simplest form, we need to multiply the two binomials using the distributive property.

First, we will multiply the first term of the first binomial by each term of the second binomial:
(2/3)x * 2x = (4/3)x^2
(2/3)x * (5/6) = (10/18)x = (5/9)x

Next, we will multiply the second term of the first binomial by each term of the second binomial:
(4/3) * 2x = (8/3)x
(4/3) * (5/6) = (20/18) = (10/9)

Now we will combine like terms:
(4/3)x^2 + (5/9)x + (8/3)x + (10/9) = (4/3)x^2 + (13/9)x + (10/9)

Therefore, the product of ((2)/(3)x+(4)/(3)) and (2x+(5)/(6)) as a trinomial in simplest form is (4/3)x^2 + (13/9)x + (10/9).
