Answer:

There are in cents: 3 or 4 if you count it. And in dollars: 4 different ways to make 30 dollars or 30 cents.


Step-by-step explanation:

Cents: 30 pennies

6 nickels

3 dimes

if you can use both : 1 nickel and a quarter

I can not tell if that is 30 dollars or 30 cents so I will do both :

Dollars: 300 pennies

60 nickels

30 dimes

120 quarters

<h3>Hey there! </h3><h3>Pennies = p  (it costs 1 cent ) </h3><h3>Nickles = n ( it costs 5  cents ) </h3><h3>Dimes = d it costs 10 cents ) </h3><h3>Quarters = q ( it costs 25 cents ) </h3><h3 /><h3>The quarters wouldn't necessarily give you the result of  30 because a quarter itself cost of a quarter would be 25 cents so your answer would be too high or too low to give you 30</h3><h3>So, this means you could ONLY use the <u>pennies ,nickles, and dimes </u></h3><h3>Actual answers.......................</h3><h3>Number of <em>pennies</em> would be: 30</h3><h3>Number of <em>nickles</em> would be: 6</h3><h3>Number of <em>dimes</em>: 3</h3><h3>Number of  <em>quarters </em> including the <em>nickles: </em>1 quarter and 1 nickle</h3><h3>Good luck on your assignment and enjoy your day! </h3><h3>~LoveYourselfFirst:)</h3>

Nigel bought 10 pencils and 5 erasers for 8$. The price of 2
Jlenok [28]

Answer:

2 erasers cost <u><em>$1.20</em></u>

Step-by-step explanation:

Nigel bought 10 pencils and 5 erasers for $8.

We can write this algebraically:

10p + 5e = 8

We know that the price of 2 pencils is $1. That is $0.50/Pencil.

So, p = $0.50. Now we can plug that into out equation and find the price of one eraser:

10(0.50) + 5e = 8

5 + 5e = 8

5e = 3

e = $0.60

Now, we have the price of one eraser,<em> </em><u><em>$0.60</em></u>, and we can multiply this by 2 to find the price of 2 erasers, which equates to <u><em>$1.20</em></u>.

A person earns ?$18 comma 200 one year and gets a? 5% raise in salary. What is the new? salary?
frozen [14]

Answer:

Her new salary would be 19,110

Step-by-step explanation:

To find the new salary, start by finding the amount of the raise. You can do this by multiplying the former amount by the percentage of the raise.

18,200 * 5% = 910

Now we add the old salary to the amount of the raise.

18,200 + 910 = 19,110

Last homework for mathematics, mr Thompson!
Flura [38]

Answers:

  1. Have a common difference
  2. Have a common factor
  3. Have a linear first difference

============================================================

Explanation:

Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.

------------------

Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.

------------------

Quadratic functions are a bit strange.

Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....

Let's subtract the adjacent terms (larger - smaller)

  • 4-1 = 3
  • 9-4 = 5
  • 16-9 = 7
  • 25-16 = 9

Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.

------------------

For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.
