cory earns 52.50 in 7 hours. find the unit rate

There are 9 hours between 8:30 am to 5:30 pm

From the question, we have the following parameters that can be used in our computation:

Initial time  = 8:30 am

Final time = 5:30 pm

using the above as a guide, we have the following:

Number of hours = Final time - Initial time  

substitute the known values in the above equation, so, we have the following representation

Number of hours = 5:30 pm - 8:30 am

Evaluate

Number of hours = 9 hours

Hence, there are 9 hours between 8:30 am to 5:30 pm

Answer:

Step-by-step explanation:

GCF(18, a, 20ab) = 1

18 and a do not necessarily have any factor in common, so their GCF is 1. Adding more terms to the list will not increase the GCF beyond that value.

Answer:

gross pay = $552.50

Step-by-step explanation:

Kenneth earns a commission on his total sales = [tex]4\frac{1}{2}[/tex] %

                                                                              = [tex]\frac{9}{2}[/tex] %

                                                                              = 4.5%

If his sales are 4500 this week.

His commission would be = 4.5% × 4500

                                           =  [tex]\frac{4.5}{100}\times 4500[/tex]

                                           = 0.045 × 4500

                                           = $202.50

His weekly salary is $350

Gross pay = 350 + 202.50 = $552.50

Kenneth's gross pay would be $552.50 this week.

the solution is[tex]\( n \geq -9 \).[/tex]

Sure, let's break down the problem step by step.

1. The inequality given is[tex]\( 6 \leq n + 15 \).[/tex]

2. To find the value of ( n ), we'll start by isolating ( n ) on one side of the inequality.

[tex]6 &\leq n + 15 \\6 - 15 &\leq n \\-9 &\leq n[/tex]

So, the solution is[tex]\( n \geq -9 \).[/tex]

Now, let's explain the steps and the final answer in more detail.

The inequality[tex]\( 6 \leq n + 15 \)[/tex] states that "six is less than or equal to the sum of a number ( n ) and fifteen."

To solve for ( n ), we first subtract 15 from both sides of the inequality to isolate ( n ):

[tex]\[ 6 - 15 \leq n \][/tex]

This simplifies to:

[tex]\[ -9 \leq n \][/tex]

So, the solution to the inequality is[tex]\( n \geq -9 \),[/tex] which means that any number greater than or equal to -9 will satisfy the original inequality [tex]\( 6 \leq n + 15 \).[/tex]

In conclusion, the correct answer is[tex]\( n \geq -9 \)[/tex], and this means that any number greater than or equal to -9 makes the statement "six is less than or equal to the sum of that number and fifteen" true.

The term 'trapezoid' refers to a four-sided figure with at least one pair of parallel sides in American English, while 'trapezium' is the equivalent term in British English.

Explanation:

Other names for a trapezoid include trapezium in British English. The term trapezoid is commonly used in American English to describe a four-sided figure with at least one pair of parallel sides. In contrast, British English refers to the same shape as a trapezium. It is important not to confuse these terms with trapezius, which is a muscle in the human body, or other unrelated terms such as triad or tricarboxylic acid cycle (TCA).

The amount of fluorine (in grams) on second sample is,

⇒ 2062.5 g.

Here,

On Sample one, 1.65 kg Magnesium and 2.57 kg Fluorine.

And, On second sample, 1.37 kg of magnesium and let x kg of fluorine.

We have to find the amount of fluorine (in grams) on second sample.

What is Ratio?

Ratios compare two numbers, usually by dividing them.

Now,

On Sample one, 1.65 kg Magnesium and 2.57 kg Fluorine.

And, On second sample, 1.37 kg of magnesium and let x kg of fluorine.

Hence,

The ratio from sample one,

⇒ 1.65kg / 2.57kg = 0.64

The ratio of second sample,

⇒ 1.3 kg / x kg

Now, Using Law of define properties of ratio, the first and second should have the same ratio.

Hence,

1.3 kg / x kg F = 0.64

x = 2.0315 kg F

x = 2031.2 g F

Therefore, The amount of fluorine (in grams) on second sample is,

⇒ 2062.5 g.

The sentence 'The difference of Rhonda's height and 16 is 52' translates into the equation 'h - 16 = 52'. Here, 'h' represents Rhonda's height.

The subject matter of this question falls under Mathematics. Specifically, it deals with basic algebra where you have to translate word problems to an algebraic equation. Remember that the phrase 'the difference of' in math refers to the operation of subtraction. So, when you read 'the difference of Rhonda's height and 16 is 52,' that means Rhonda's height (which we’ll denote as 'h') minus 16 equals 52 (52 comes from the phrase 'is 52' because 'is' usually represents equal '='). Therefore, when this sentence is written in the form of an equation, it will look like: h - 16 = 52.

Final answer:

To factor the expression 10x + 40, we can factor out the greatest common factor (GCF) of 10 from both terms, resulting in 10(x + 4).

Explanation:

To factor the expression 10x + 40, we can first find the common factor for both terms, which is 10. Factoring out 10, we get 10(x + 4). This expression represents the original 10x + 40. In simpler terms, we've taken out the common factor of 10 from both terms, leaving us with 10 multiplied by the quantity (x + 4). This factored form is useful for simplifying expressions or solving equations. Essentially, factoring helps us break down a more complex expression into simpler parts, making it easier to work with and understand in various mathematical contexts.

There are 10 spaces then the first space will be (3,1), the second one cannot be the same as the first one so it will have to be (2,1).

So it will come down to 3×2^9

There are 1536 ternary sequences of length 10 with no pair of consecutive digits the same.

The question is asking about how many ternary sequences of length 10 there can be without any pair of consecutive digits being the same. In a sequence of length 10, each digit has 3 possible values (0, 1, 2) but cannot be the same as the digit before it. Therefore, the first digit has 3 choices, and each subsequent digit has 2 choices (since it can't be the same as the previous one). Using the multiplication principle of counting, there would be 3*2^9 = 1536 such sequences.
