5. Which of the numbers, 3/12 or 2/9, is greater? How do you know?

Answers

You can find the decimal forms of 3/12 and 2/9 by dividing the numerators of each of the fraction by its denominator.

The decimal form of 3/12 is 0.25.

The decimal form of 2/9 is 0.222.

The decimal form of 3/12 is a terminating decimal.

The decimal form of 2/9 is a repeating decimal.

The greater fraction is 3/12. This is because the hundredth value of 3/12 in decimal form is greater than that of 2/9.

What are the decimal forms?

A fraction is a non-integer that has a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A decimal is a number that is made up of integers and non-integers that are separated by a decimal point. The integers are before the decimal point. The non-integers are after the decimal point. In order to convert a fraction to a decimal, divide the numerator by the denominator.

3 / 12 = 0.25

2 / 9 = 0.22

A terminating decimal is a decimal that ends. A repeating decimal is a number that does not end. An example of a terminating decimal is 0.25, 0.1. An example of a repeating decimal is 0.33, 0.222.

The function rule for this scenario can be written in slope-intercept form as: y = 6x + 30.

How to Write a Function Rule?

A function rule can be written in slope-intercept form using the unit rate or slope (m), and the starting value/initial value or y-intercept (b). The values of m and b, when determined, are simply plugged into the equation, y = mx + b.

We are given that the design fee that is charged by the cloth designer is a fixed fee of $30. This means that the starting value or y-intercept (m) is 30.

From the problem, we are also given that the additional charge per shirt printed is $6, this also implies that the slope or unit rate (m) of the function is 6.

To write a function rule in slope-intercept form, substitute m = 6 and b = 30 into y = mx + b:

y = 6x + 30.

The function rule for the cost of t-shirt produced based on the number of shirts is expressed as: y = 6x + 30.

There are 18 jars of crunchy peanut butter.
What is the total number of jars of peanut

Answers

Using ratio, the total number of peanut butter on the shelf is 144.

What is the ratio?An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

So, the ratio of creamy to crunchy peanut butter:

5:3

If there are 18 jars of crunchy peanut butter, the total number of peanut butter will be:

5(18):3(18)90:54

Total ⇒ 90 + 54 = 144

Therefore, using ratio, the total number of peanut butter on the shelf is 144.

Answers

The weighted mean for three exams is 78.1%.

Define weighted mean.

The weighted mean is a form of mean that is computed by averaging all the products after multiplying the weight (or probability) connected to a specific event or result by its connected quantitative outcome. The difference between the weighted arithmetic mean and a regular arithmetic mean is that certain data points contribute more to the final average than others, as opposed to all data points contributing equally. In mathematics, the average value of the data is determined using the weighted mean. When calculating the weighted mean, the average value can be determined by giving various weights to some of the individual variables.

Answers

(x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15 as there is no remaider.

What is a factor of a polynomial?

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given a polynomial function f(x) = x³ - x² - 17x -15.

If (x - 5) is it's factor then f(5) = 0.

∴ f(x) = x³ - x² - 17x -15.

f(5) = 5³ - 5² - 17(5) - 15.

f(5) = 125 - 25 - 85 - 15.

f(5) = 0.

So, the remainder is zero hence (x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15.

If a body is moving in the horizontal axis with a velocity Vx= 6m/s and in the vertical axis Vy=8m/s, the magnitude of the velocity of the body V is 10

The given parameters are;

The velocity of the body relative to the horizontal axis, vₓ = 6 m/s

The velocity of the body relative to the vertical axis,  = 8 m/s

Required;

The measure of the magnitude of the velocity of the moving body, v

The velocity of the body can be represented vectorially as follows;

v = 6·i + 8·j

|V| = [tex]\sqrt{Vx^{2} + Vy^{2} }[/tex]

|V| = [tex]\sqrt{6^{2} + 8^{2} }[/tex]

Answers

The volume of the sphere that snugly fits into the cylinder of volume 432π cube units is 288 cube units.

It is given that

The fall snugly fits inside the cylindrical jarThe ball touches the top and bottom of the cylindrical jar

Therefore, from the image attached we can infer that

the diameter of the sphere and the cylinder is the same
hence, they have the same radius.the height of the cylinder is the same as the diameter of the sphere, i.e twice the radius

Let the radius of the cylinder and the sphere be r units

Let the height of the cylinder be h units.

Hence h = 2r units

We know that the volume of the Sphere is 4/3πr³

The volume of a cylinder is πr²h

= πr² X 2r

= 2πr³ units cube

According to the problem,

2πr³ = 432π

Multiplying L.H.S with 2/3 gives us

4/3πr³ = 2/3 X 432π

or, 4/3πr³ = 288π
