There were Math and Science books in one section of a library. Before an addition of 84 Math books, the ratio of Math books to Science books was 3 : 7. How many Science books were there if the eventual ratio of Math books to Science books was 6 : 7?
Answers
Answer:
196 science books
Step-by-step explanation:
Check the attachment.
The total number of sicience books were 196.
What is ratio?Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Let the total numbers of science books be x and maths books be y.
According to the given question.
The intial ratio of maths books to the science books is 3:7.
⇒ [tex]\frac{y}{x} = \frac{3}{7}[/tex] ...(i)
But, after the addition of 84 maths books the ratio gets changed to 6:7.
[tex]\implies \frac{y +84}{x} = \frac{6}{7}[/tex] ...(ii)
Solving the equations i and ii.
From equation i.
[tex]7y = 3x[/tex]
And from equation ii
[tex]7y + 7(84) = 6x[/tex]
Substitute the value of 7y = 3x in the above equation.
[tex]3x + 588 = 6x[/tex]
[tex]\implies 588 = 6x -3x[/tex]
[tex]\implies 3x = 588[/tex]
[tex]\implies x = \frac{588}{3}[/tex]
[tex]\implies x = 196[/tex]
Hence, the total number of sicience books were 196.

ABC ~ DEF. What sequence of transformations will move ABC onto DEF?
Answers
The transformation that is implemented is clockwise rotation by 270° about the origin and dilation by a scale factor of 1/2 .
The process of transformation an existing graph or equation into a new graph is known as graph transformation . The alteration of algebraic equations is a typical form of algebraic challenge.
A transformation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of transformation . The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).
In the given figure we can see that the length of the side BC of the figure is 4 units, where as the length of the corresponding side in the image is
2 units . Hence the image is dilated buy a scale factor of 1/2 .
And from the transformation figure it is clear that the image has rotated either 270° clockwise or 90 ° counterclockwise.
Hence the second option on transformation is correct.

Mr. Schultz is randomly distributing 15 rulers with centimeter markings and 10 rulers without centimeter markings to his class. What is the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings?.
Answers
Using it's concept, it is found that there is a 0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the first ruler, there are 15 with markings out of 25, hence P(A) = 15/25.For the second ruler, there are 10 without markings out of 24, hence P(B|A) = 10/24.Thus, the probability is given by:
[tex]P(A \cap B) = P(A)P(B|A) = \frac{15}{25} \times \frac{10}{24} = 0.25[/tex]
0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.

5. If your father earns Rs. 40,000/-, mother earns Rs. 35,000/- and your brother earns Rs. 25,000/- per month and your friend's father earns Rs. 45,000/-, mother Rs.30,000/- and brother earns Rs. 15,000/- then whose monthly income is more and by what percent.
Answers
Answer:
✏The correct option is B Rs 73,333
Per capita income is the sum of all income sources, divided by the total number of people. Here the gross income of the family is = Rs (1,80,000+ 40,000) = Rs 2,20,000, the pocket money won't be added as it is an expense for the family. Then the per capita income of the family= Gross income / 3 (as the family has three members) = Rs 73,333.
Step-by-step explanation:
Percent is a relative quantity. Earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)
How to find how much percent 'a' is of 'b'?Percent is a relative quantity, as it is the measure of one quantity per 100 units of other quantity.
Suppose a number is 'a'Suppose another number is 'b'We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
For this case, we're specified that:
For our family:
Income of father = ₹ 40,000Income of mother = ₹ 35,000Income of brother = ₹ 25,000Total monthly income = ₹(40000 + 35000 + 25000) = ₹100,000
For friend's family:
Income of father = ₹ 45,000Income of mother = ₹ 30,000Income of brother = ₹ 15,000Total monthly income = ₹(45000 + 30000 + 15000) = ₹90,000
Thus, we see that friend's family's monthly is monthly ₹10,000 less than our family's monthly income.
We need to find how much percent this ₹10,000 is of their family because we need to find by how much percent our family's income is more than the friend's family's monthly income (so comparison is with respect to the monthly income of friend's family).
Let P be the percent the ₹10,000 is of the amount ₹90,000
Then, we get:
[tex]P = \dfrac{10000}{90000} \times 100 = \dfrac{100}{9} \approx 11.11 \%[/tex]
Thus, earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)

In circle K with m \angle JKL= 144m∠JKL=144 and JK=6JK=6 units, find the length of arc JL. Round to the nearest hundredth
Answers
The length of arc JL is approximately 15.08 units.
We have,
The length of an arc in a circle can be calculated using the formula:
Arc Length = (θ/360) * 2πr
where θ is the central angle in degrees, r is the radius of the circle, and 2π is approximately 6.28.
In this case, we are given the central angle JKL = 144° and the radius JK = 6 units.
Plugging in the values, we have:
Arc Length = (144/360) * 2π * 6
Arc Length ≈ (0.4) * 6.28 * 6
Arc Length ≈ 15.072 units
Rounded to the nearest hundredth,
The length of arc JL is approximately 15.08 units.
Thus,
The length of arc JL is approximately 15.08 units.
