You are making sets of pens and pencils to sell. You want each set to contain the same combination of pens and pencils. You have 28 pens and 80 pencils, and you want to use them all. What is the greatest number of these sets you can make?
The greatest number of sets of pens and pencils that can be made, using all of the given 28 pens and 80 pencils in each set, is 4. Each set would contain 7 pens and 20 pencils.
Explanation:In the problem, we are looking to find the Greatest Common Divisor (GCD), which is the greatest number that can evenly divide both the number of pens (28) and the number of pencils (80). The GCD between 28 and 80 is 4.
Thus, the most sets of pens and pencils you can make would be equal to the GCD, which in this case is 4.
This means you can put together 4 sets with an equal number of pens and pencils in each set. In each of these sets, there would be 7 pens (28 pens ÷ 4 sets) and 20 pencils (80 pencils ÷ 4 sets).

Natasha is observing the growth of a population of bacteria. She started out with 250 bacteria cells. The population of bacteria quadruples every hour. Use x to represent the number of hours and y to represent the population of the bacteria. Enter an equation that represents this scenario in the box.
Answer:
[tex]y=250(5)^x[/tex]
Step-by-step explanation:
The growth of a population of bacteria can be represented by exponential growth function,
[tex]y=a(1+r)^x[/tex]
where,
y = the population of the bacteria after x hours,
x = the number of hours,
a = initial population of bacteria,
r = rate of growth,
At the beginning the number bacteria was 250 and the population of bacteria quadruples every hour i.e rate of growth is 400% or 4 per hour.
Putting all the values,
[tex]y=250(1+4)^x[/tex]
[tex]\Rightarrow y=250(5)^x[/tex]
At the beginning of the week Fayez writes down the mileage of his limo at 2529 at the end of the week the mileage is 2834, Fayez knows he used 75.2 litres of petrol during this week. The handbook states the limo uses 1 gallon of petrol for every 20 miles. Fayez wants to know if his limo uses 1 gallon of petrol for every 20 miles that week. 1 gallon = 4.54 litres . Did his limo use 1 gallon of petrol every 20miles that week. Show your answer clearly
Answer:
No. It used 1 gallon in 18.41 miles.
Step-by-step explanation:
He travelled 2834 - 2529 = 305 miles.
So his consumption is 305 / 75.2 = 4.056 miles/litre.
This equals 4.056*4.54 = 18.41 miles / gallon.
So this is less than the 1 gallon every 20 miles stated by the handbook.
Answer: His limo used 1 gallon fuel for 18.4136 miles.
Step-by-step explanation:
Fayez covered distance:
2834 - 2529 = 305 miles.
He used fuel = 75.2 litres
75.2/4.54 = 16.5638 gallons petrol used.
His limo covered distance / total petrol used = 305 miles / 16.5638 gallons petrol = 18.4136 miles per gallon.
That is less than 20 miles per gallon
Brian works 40 hours a week. He spends 40% of his time helping customers, 13% doing paperwork, and the remainder performing other store tasks. What percentage of Brian's time is spent on other store tasks?
40% helping customers + 13% doing paper work = 53% of his time.
This means 100% - 53% = 47% of his time he is doing other tasks.

18x - 54 :) :( :) :)At the art fair, 95 artists exhibited their work. Of those 95 artists, 25 showed sculptures and 48 showed paintings. If 12 showed both sculptures and paintings, how many artists showed only sculptures or paintings?
To determine the number of artists who showed only sculptures or paintings at the art fair, we use the formula for the principle of inclusion-exclusion, resulting in 61 artists.
Explanation:To find out how many artists showed only sculptures or paintings at the art fair, we apply the principle of inclusion-exclusion. First, we add the number of artists who showed sculptures (25) to those who showed paintings (48), which gives us a total of 73 artists. However, this counts the 12 artists who showed both sculptures and paintings twice, so we subtract 12 from this total to correct for the double counting. Therefore, the number of artists who showed only sculptures or paintings is 73 - 12, which equals 61 artists.

Solve using substitution
x=2y-6
y= -3x+17
Answer:
(x, y) = (4, 5)
Step-by-step explanation:
given the 2 equations
x = 2y - 6 → (1)
y = - 3x + 17 → (2)
Either substitute x = 2y - 6 into (2) or y = - 3x + 17 into (1)
substituting y = - 3x + 17 into (1)
x = 2(- 3x + 17) - 6
x = - 6x + 34 - 6
x = - 6x + 28 ( add 6x to both sides )
7x = 28 ( divide both sides by 7 )
x = 4
substitute x = 4 into (2)
y = - 12 + 17 = 5
solution is (4, 5 )

Divide (x^3-8x^2+17x-10)/(x-5)
Answer:
(x - 2)*(x - 1) is the answer
Step-by-step explanation:
We have to divide the polynomial f(x) = x^{3}-8x^{2}+17x-10 by (x-5).
Now, after dividing f(x) gets simplified into (x-5)*(x^{2}-3x+2).
So, we need to factorize the quadratic equation x^{2}-3x+2.
i.e. x^{2} - 3x + 2 = x^{2} - x - 2x + 2 = x(x-1) - 2(x-1) = (x - 2)*(x - 1)
Therefore, f(x) again gets simplified into (x-5)*(x - 2)*(x - 1)
Now eliminating the common factor (x-5).
We get, [tex]\frac{x^{3}-8x^{2}+17x-10}{x-5}[/tex] = (x - 2)*(x - 1)

Answer:
Step-by-step explanation:
Given that a storage rack has dimensions as 25x12x5 ft.
Box has dimensions as 15x8x10 inches
Volume of each box = 15(8)(10) = 1200 inches = 1200x12^(-3) feet^3
Volume of 5000 boxes = 5000 (1200x12^(-3) ) = 3472.22 cubic feet
Volume of storage rack = 25(12)(5) = 1500 cubic feet
Volume of 25 storage racks 1500(25) = 37500 cubic feet.
SInce storage racks have sufficient volume it is concluded that enough storage is there.
Answer:
Yes, we have enough storage space.
Step-by-step explanation:
25 storage racks that are:
Length: Lsr = 25 ft = 25 ft (12 in / 1 ft) → Lsr = 300 in
Width: Wsr = 3 ft = 3 ft (12 in / 1 ft) → Wsr = 36 in
Height: Hsr = 12 ft = 12 ft (12 in / 1 ft) → Hsr = 144 in
5000 boxes 15x8x10 in
Length: Lb = 15 in
Width: Wb = 8 in
Height: Hb = 10 in
In the length of each storage rack we can put:
Nl=Lsr/Lb=300 in / 15 in → Nl = 20
In the width of each storage rack we can put:
Nw=Wsr/Wb=36 in / 8 in = 4.5 → Nw = 4
In the height of each storage rack we can put:
Nh=Hsr/Hb=144 in / 10 in = 14.4 → Nh = 14
Then we can put in each storage rack:
N = Nl Nw Nh = (20)(4)(14) → N=1,120 boxes
And we have 25 storage racks, then we can storage in total:
Nt=25N=25(1,120)→Nt=28,000 boxes
And we have 5,000 boxes, then we have enough storage space
