yes I think it do make sense
Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
Given : 58% of 121.
To find : estimate 58% of 121 by using 10%.
Solution : We have given 58%
Estimate of 58% is 60%
We need to use 10%
We can write 60% as 6 times of 10%
Since , 10% of 121
= 12.1
60% = 6 times of 10%
Plugging the values
60% == 6 times of 12.1
6 *12.1 = 72 .6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Therefore, 58% of 121 by using 10% is 70.18.
By using the concept of reciprocal of fraction, the result obtained is -

What is reciprocal of a fraction?
At first, it is important to know about fraction.
Suppose there is a collection of objects and a part of the collection has to be taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.
The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.
For example: is a fraction. Here, 4 is the numerator of the fraction and 7 is the denominator of the fraction.
Let p be a fraction. Reciprocal of p is a fraction in which if the fraction is multiplied by p, the result obtained is 1 (multiplicative identity)
Here,
Let the reciprocal of be x
Reciprocal of is

A. Is not a difference of squares
B. Is a difference of squares: (y − 5)2
C. Is a difference of squares: (y + 5)(y − 5)
D. Is a difference of squares: (y + 5)2
Option: C is the correct answer.
C. Is a difference of squares: (y + 5)(y − 5).
We are given a polynomial expression in terms of the variable y as follows:
Now this expression could also be written as:
This means that the expression is a difference of squares.
Also, we know that:
Here,
Hence,
y: 5,7,9,11
A y = x + 5
B y = 2x + 3
C y= 7
D y = 4x - 5
The equation that best fits the data is y = 2x + 3.
The equation that best fits the data in the table is y = 2x + 3.
To determine this, we can look at the pattern in the data. The x-values increase by 1 each time, while the y-values increase by 2 each time. This patternindicates a linear relationship, and the equation y = mx + b represents a straight line where m is the slope and b is the y-intercept.
In this case, the slope is 2 (since y increases by 2 for every 1 increase in x) and the y-intercept is 3 (the value of y when x is 0). Therefore, the equation that best fits the data is y = 2x + 3.
