Convert 45 yards of ribbon to feet through proper conversion factor. 

   (45 yards)(3 ft / 1 yard) = 135 feet

Divide this number by 5 to determine the number of 5-ft ribbon that customers can purchased.

     n = 135 ft / 5 ft = 27

Then, multiply by $0.80.

    R = (27)($0.80) = $21.6

The profit is equal to $21.6 and $13.50,

     P = $21.6 - $13.50 = $8.1

<em>Answer: $8.1</em>

Mandy is making stationery sets from 16 sheets of paper and 12 envelopes. If she wants all the sets to be identical without any
LekaFEV [45]

Answer:

  4 sets

Step-by-step explanation:

The greatest common factor (GCF) of 16 and 12 is 4. This is the largest number that evenly divides 12 and 16. It can be found by looking at the factors of those numbers:

  12 = 4·3

  16 = 4·4

Or it can be found by seeing if the difference of the numbers (4) evenly divides them both. It does, so that is the GCF.

The greatest number of sets Mandy can make is 4.

__

Each of Mandy's 4 sets will have 4 sheets of paper and 3 envelopes.

The range of which function is (2, infinity)? y = 2x y = 2(5x) y = 5x +2 y = 5x + 2
Sveta_85 [38]

Answer:

I think your functions are y=2^{x} ,y=2*5^{x} and y=2+5^{x}

If yes then then the third function which is y=2+5^{x}.

Step-by-step explanation:

The function c^{x} where c is a constant has

Domain : c\geq 0

Range : ( 0 , ∞ )

The above range is irrespective of the value of c.

I have attached the graph of each of the function, you can look at it for visualization.

  • <em>y=2^{x} ⇒ </em>This function is same as  c^{x} so its range is <em>( 0 , ∞ )</em>.
  • <em>y=2*5^{x} ⇒ </em>If we double each value of the function y=5^{x}, which has range ( 0 , ∞ ), but still the value of extremes won't change as 0*2=0 and ∞*2=∞. Therefore the range remains as <em>( 0 , ∞ )</em>.
  • <em>y=2+5^{x}</em> ⇒ If we add 2 to each value of the function y=5^{x}, which has range ( 0 , ∞ ), the lower limit will change as 0+2=2 but the upper limit will be same as ∞. Therefore the range will become as <em>( 2 , ∞ )</em>.
