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.

Answers
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
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 lea
Answers
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
A line with a slope of 5 passes through the points (1, 7) and (k, 2). What is the value of k?

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
Answers
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:
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...
