How can you tell if a number is prime or compsite
Answers
Answer:
A prime number doesn't have any factors besides one and itself. For example, 17 is a prime number because you can't multiply anything to get 17 besides 17 and 1 (excluding decimals).
Composite numbers are numbers that have other factors other than 1 and themselves. Example: 12 is a composite number because you can multiply 3 by 4 to get 12, or 2 by 6 to get 12, not just 12 times 1.

Answers
Answer: Addition and subtraction is performed after multiplication, division and remainder
Step-by-step explanation:
The correct order of operations is to calculate whatever is in the parenthesis first.
Then calculate multiplication and division depending on which comes first as you move from left to right.
Then addition and subtraction can be performed also depending on which comes first as you move left to right.
A server sees 84 customers over 6 hours. How many customers did they see in 1 hour?
Answers
Answer: 14 customers
Step-by-step explanation: Right now, you can set up an equation that looks something like this. 6h=84 (h means hours). To find the number of customers in one hour, all you have to do is isolate h on one side of the equation. To do this, just divide both sides by 6 and you should get h=14. So in one hour, this particular server sees 14 people. Hope this helps! :)

{1, 16, 36}
Step-by-step explanation:
Put the numbers in for x and see what the f(x)-values are.
(-5-1)^2 = (-6)^2 = 36
(0-1)^2 = (-1)^2 = 1
(5-1)^2 = 4^2 = 16
The range is the set of values {1, 16, 36}.

186 = 6 (3n + 7) answer for N
Answers
Answer:
n = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
186 = 6(3n + 7)
Step 2: Solve for n
Divide 6 on both sides: 31 = 3n + 7Isolate n term: 24 = 3nIsolate n: 8 = nRewrite: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 186 = 6(3(8) + 7)Multiply: 186 = 6(24 + 7)Add: 186 = 6(31)Multiply: 186 = 186Here we see that 186 does indeed equal 186.
∴ n = 8 is the solution to the equation.

Paula owns a shoe store in Los Angeles. Whenever she orders a new style of shoe, she orders 5 pairs of that style in each of the most popular sizes. The most popular sizes are 6, 7, 8, 9, and 10. She also orders 3 pairs in size 5 and 3 pairs in size 11.
For every new style, how many pairs of shoes does she need to order in total?
Answers
She orders 5 pair in 5 different sizes:
5 x 5 = 25 pair
She orders 3 pair in 3 different sizes:
3 x 3 = 9 pair
Total pairs = 25 + 9 = 34 pair.

Answers
9514 1404 393
Answer:
a) $169,234.59
b) $19,234.59
Step-by-step explanation:
The first question you must answer is whether Colleen will earn interest on her first deposit in the first year. That is, does she deposit the money at the first of the year or the end of the year?
The usual "annuity" formula assumes the deposit is at the end of the year, so no interest at all is earned on the last deposit made. If the deposit is at the first of the year, an "annuity due" formula is used, that multiplies the entire ending account value by the annual multiplier, 1.017 in this case.
__
a) Assuming an "annuity", the formula is ...
A = P((1 +r)^t -1)/r . . . . . for annual compounding at rate r for t years
A = $10,000(1.017^15 -1)/0.017 = $169,234.59 . . . . ending balance
__
b) Colleen has made 15 deposits of $10,000, for a total of $150,000, so the amount of interest earned is ...
$169,234.59 -150,000 = $19,234.59 . . . . interest earned
Alexis and Paige work together as photographers for the local newspaper. Alexis is paid $25 for each news story she shoots and an additional $5 per picture. Paige makes $15 for each news story and $10 per picture. Write an expression to show how much the newspaper will pay if Alexis and Paige are hired together. Use p as the variable for pictures
Answers
Answer:
The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.
Step-by-step explanation:
Given that:
Alexis charges $25 for each news story and $5 per picture.
Let,
n represent the number of news stories and p represent the number of pictures.
Alexis' total charges = [tex]25n+5p[/tex]
Paige charges $15 for each news story and $10 per picture.
The variables will be same.
Paige's total charges = [tex]15n+10p \\[/tex]
Alexis and Paige's charges will be added if newspaper hire them together.
Total charges paid by newspaper = [tex]25n+5p+15n+10p=40n+15p[/tex]
Hence,
The expression 40n+15p shows the amount paid by the newspaper if Alexis and Paige are hired together.

Your last visit is to the famous tourist attraction, the one and only Empire State Building! Your Boss wants you to double check your coworker’s measurements to determine if the scale drawing replicated is proportional to the actual Empire State Building.
Lastly, your Boss wants to know if your coworker’s scale drawing is an enlargement or reduction? Your coworker’s dimensions are 5.15 by 6.30 square feet. While the Empire State Building is 7.21 by ________________. What is the missing measurement of the side?Is this an enlargement or reduction?Explain why.
(Please explain thoroughly step by step how you solved the problem.If you can,please provide an image of how you solved the problem.)
Answers
Work Shown:
(5.15)/(6.30) = (7.21)/(x)
5.15*x = 6.30*7.21 ....... cross multiply
5.15x = 45.423
x = (45.423)/(5.15) ...... dividing both sides by 5.15
x = 8.82

hey um, so i’m learning ab percentages in my math class so can someone please explain to me how to solve percent problems if that’s ok? thank you.
Answers
Answer:
It's pretty simple. For example, if it says there is a percentage increase on something like there is a jacket for $25 and there was a 15% increase, you multiply 25 by 1.15 to see what the new price is. But say if the same $25 jacket is on sale for 15%, then you can multiply 25 by .15, then subtract that from 25 or originally subtract the 15% from 100 which is 85 and multiply 25x.85 and get the answer directly.

Diagnostic tests of medical conditions can have several types of results. The test result can be positive or negative, whether or not a patient has the condition. A positive test (+) indicates that the patient has the condition. A negative test (−) indicates that the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 200 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.
Assume the sample is representative of the entire population. For a person selected at random, compute the following probabilities. (Enter your answers as fractions.) Test Result Test Result Column Total Condition Present 105 24 129 Condition Absent 25 46 71
