if the original price is $40 and the discount price is $25, what is the percent discount?
Answer:
i think its 62.5%
Step-by-step explanation:
have a good day :)
Answer:
37.5%
Step-by-step explanation:
Ok I always do these problems in a weird way cuz im autistic but here's my process...
10% of 40 is 4
5% of 40 is 2
2.5% of 40 is 1
4 goes in to 25 6 times
4x6=24
which is one less than 25
so there's six 10%s which is 60%
plus the extra 2.5%
so it's 62.5%
so the item is 37.5% off...

In a certain chemical, the ratio is zinc to copper is 4 to 15. A jar of the chemical contains 570 grams of copper, how many zinc does it contain
Answer:
zinc = 152 grams
Step-by-step explanation:
Ratio of zinc to copper = 4 : 15
Copper = 570 grams
zinc = x grams
Find x
Ratio of zinc to copper = x : 570
Equate both ratios
4 : 15 = x : 570
4/15 = x/570
Cross product
4 * 570 = 15 * x
2,280 = 15x
x = 2,280/15
= 152
x = 152 grams
zinc = 152 grams

Answer:
at least 5
Step-by-step explanation:
If the question was similar to the one given below
A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter or a pair of distinct letters written in alphabetical order. What is the least number of letters that can be used if there are 12 participants, and each participant is to receive a different code?
The answer would be as follows
If we use 3 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
4C2= 6 ways to use these letters and the comma
If we use 4 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
5C2= 10 ways to use these letters and the comma
If we use 5 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
6C2= 15 ways to use these letters and the comma
We need the least number of the alphabets to assign codes to 12 participants.
So the least number of alphabets is 5 because it can give codes to at least to 12 people .
Pair of alphabets + distinct letter ≥ 12
5 + 1 ≥ 12
6c2 ≥ 12
15 ≥ 12
What is this number in standard form?

the logo shown has a total area of 125cm^2 and the square has a side length of 5cm. Calculate the width of the logo
Answer:
25cm
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

A landscaper is constructing a rectangular garden with an area of 108 square feet. He draws the garden on paper and represents the length as and the width as (x-1) . Find the length and the width of the garden(x-4). Select all that apply
7 feet
8 feet
9 feet
12 feet
13feet
plssss help
The length and width of the garden is 12 feet and 9 feet respectively.
Given that, length of garden [tex]=(x-1)[/tex]
Width of garden [tex]=(x-4)[/tex]
Area of garden is 108 square feet.
[tex]Area=length*width\\\\108=(x-1)*(x-4)\\\\x^{2} -5x+4=108\\\\x^{2} -5x-104=0\\\\x^{2} -13x+8x-104=0\\\\x(x-13)+8(x-13)=0\\\\(x-13)(x+8)=0\\\\x=13,x=-8[/tex]
Since, side can not be negative.
So we will consider, [tex]x=13[/tex]
Length[tex]=x-1=13-1=12feet[/tex]
Width[tex]=(x-4)=13-4=9feet[/tex]

Aaron can paint a door in 3 hours, and Anna can do the same job in 2 hours. Working together, how many hours will it take them to paint a door?
1.25 hours will it take them to paint a door.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Aaron can paint a door in 3 hours.
Anna can do the same job in 2 hours.
Since you have two painters for one door we can calculate the average of their combined times as
= (3 h + 2 h) /2
= ( 180 + 120) /2
= 300/ 2
= 150 minutes.
= 150/ 2
= 75 min
= 75/ 60
= 1.25 hours.
It would take nearly 1 hour and 25 minutes.

Complete Question
Kelvin finished 2/3 of his test in a 1/2 hour. Express this rate in hours per test.
Answer:
3/4 hours per test
Step-by-step explanation:
2/3 of his test = 1/2 hour
This rate in hours per test is calculated as:
x = 1/2 /2/3
x = 1/2 hour ÷ 2/3 test
x = 1/2 × 3/2
x = 3/4 hours per test
This rate in hours per test is given as 3/4 hours per test
