green foods purchases packages of noodles by the carton. each carton contains 36 packages and costs $43.20. green foods sells the noodles for $2.29 per package. what is the markup per carton?
Answer:
91% markup
Step-by-step explanation:
$43.20 divided by 36 is $1.20 per package
if Green Foods is selling one package for $2.29 then they are marking each package up by $1.19
if you take the difference of the per carton prices (82.44-43.20) and divide it by 43.20, you get a 91% markup

Right triangles have the measure of one of its angles to be 90 degrees
The ratio WY/WX is 0.36
From the triangle (see attachment), one of the angles of triangle WXY is 70 degrees.
This means that, the triangle is similar to triangle 1.
Similar triangles may or may not have congruent side lengthsSimilar triangles have equivalent ratiosSo, by comparing the side lengths, we have:
[tex]WY = 3.4[/tex]
[tex]WX = 9.4[/tex]
The ratio is then calculated as:
[tex]\frac{WY}{WX}= \frac{3.4}{9.4}[/tex]

A local pizza parlor is selling two different shapes of cheese pizza for the same price. You can get two small square pizza that have sides of 7 inches or a large round pizza with a diameter of 12 inches. Which choice gives you more pizza
Answer:
It is a good idea to buy the round pizza, since it has a total of 113.04 square inches of pizza, while the two square slices together bring together 98 square inches.
Step-by-step explanation:
Since a local pizza parlor is selling two different shapes of cheese pizza for the same price, and you can get two small square pizza that have sides of 7 inches or a large round pizza with a diameter of 12 inches, to determine which choice gives you more pizza the following calculations must be carried out, knowing that the area of a square is equal to pi multiplied by the radius squared, and that the area of a square is equal to its side squared:
Round pizza:
Radius = Half the diameter
3.14 x 6 ^ 2 = X
3.14 x 36 = X
113.04 = X
Square pizzas:
(7x7) x 2 = X
49 x 2 = X
98 = X
Therefore, it is a good idea to buy the round pizza, since it has a total of 113.04 square inches of pizza, while the two square slices together bring together 98 square inches.

Find the volume of the box.
3 ft
4 ft
5 ft
The volume of the box is
cubic feet________
Answer:
60 ft³
Step-by-step explanation:
GIVEN :-
Length of cube = 5 ftWidth of cube = 4 ftHeight of cube = 3 ftTO FIND :-
Volume of cubeFACTS TO KNOW BEFORE SOLVING :-
Volume of a cube = Length × Width × Height
SOLUTION :-
In the question , all the dimensions of the cube is given. So,
Volume of the cube = 5 × 4 × 3 = 60 ft³
Based on the calculation, the volume of the box is 60 cubic feet.
How to calculate the volumeTo find the volume of a box, you need to multiply its length, width, and height. In this case, the dimensions of the box are given as:
Length = 3 ft
Width = 4 ft
Height = 5 ft
To calculate the volume, multiply these dimensions together:
Volume = Length × Width × Height
Volume = 3 ft × 4 ft × 5 ft
Volume = 60 cubic ft
Therefore, the volume of the box is 60 cubic feet.

Suppose we want to choose 4 colors, without replacement, from 18 distinct colors.
(a) If the order of the choices is relevant, how many ways can this be done?
(b) If the order of the choices is not relevant, how many ways can this be done?
Answers:
(a) 73440(b) 3060=====================================================
Explanation for part (a)
Consider four slots labeled A,B,C,D.
We have
18 choices for slot A17 choices for slot B16 choices for slot C15 choices for slot DWe started at 18 and counted down until we filled the four slots. The countdown is because we cannot repeat a color. Multiply out those values to get the answer: 18*17*16*15 = 73440
You can use the nPr permutation formula as an alternative method
[tex]_nP_r = \frac{n!}{(n-r)!}[/tex]
in this case n = 18 and r = 4. The exclamation marks indicate factorial.
-----------------------------------
Explanation for part (b)
Let's say we had color labels A,B,C,... all the way up to R which is the 18th letter in the English alphabet. From those 18 letters, we can only pick four. Let's say we pick D,E,F,G.
Focusing solely on the set {D,E,F,G}, we only have one set and the order doesn't matter. So {D,E,F,G} is the same as {D,E,G,F}.
There are 4*3*2*1 = 24 ways to arrange those four items meaning that we'll need to divide the result of part (a) by 24 to get the result of part (b)
73440/24 = 3060
You could use the nCr combination formula to get the same result
[tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex]
where n = 18 and r = 4 are the same from last time.
The connection between nPr and nCr is this
[tex]_nC_r = \frac{_nP_r}{r!}[/tex]
which can be rearranged into
[tex]_nP_r = r!*\left( _nC_r \right)[/tex]
these formulas are handy to help us go back and forth between nCr or nPr.
If the order of the choices is relevant, the number of ways of selecting 4 colors out of 18 distinct colors is 73440.
If the order of the choices is not relevant, the number of ways of selecting 4 colors out of 18 distinct colors is 3060.
What are combination and permutation?Combination is a way of selecting items from a collection where the order of arrangement is not relevant.
It is given by:
[tex]^nC_r[/tex] = n! / r! (n-r)!
Permutation is a way of selecting items from a collection where the order of the arrangement is relevant.
It is given as:
[tex]^nP_r[/tex] = n! / (n-r)1
We have,
Number of distinct colors = 18
Number of colors to be chosen = 4
The number of ways the four colors be chosen when the order is not relevant:
= [tex]^{18}C_4[/tex]
= 18! / 4! 14!
= 18 x 17 x 16 x 15 / 4 x 3 x 2
= 3060
The number of ways the four colors be chosen when the order is relevant:
= [tex]^{18}P_4[/tex]
= 18! / 14!
= 18 x 17 x 16 x 15
= 73440
Thus,
If the order of the choices is relevant, the number of ways of selecting 4 colors out of 18 distinct colors is 73440.
If the order of the choices is not relevant, the number of ways of selecting 4 colors out of 18 distinct colors is 3060.

Area of the shaded region = area of the outer rectangle - area of the inner rectangle
Area of the outer rectangle
l = 42
b = 25
a = l*b = 42*25 = 1050m^2
Area of the inner rectangle
l = 22
b = 20
a = l*b = 22*20 = 440m^2

Ahmad deposits $3000 into an account that pays simple interest at a rate of 3% per year. How much interest will he be paid in the first 4 years?
Answer:
.......
Step-by-step explanation:
Jahlan, simple interest means that interest is paid every year on the original $4000.
To find 2% of 4000, you multiply 4000(.02) = $80.
Since the interest is the same, 3(80) = $240.
