In a book store,60 books of the same kind occupy 1.4m of shelf length . how much shelf length is required for 300 such books ? if a shelf is 84cm long,how many books are needed to fill the shelf?
7m shelf length is required for 300 such books, and 36 books are needed to fill the 84cm long shelf. So option (a). 7m,36 books is the correct option.
here in the question we need to apply concept of division.
what is division ?
Division is kind of mathematical operation where we find out equals parts of a number, by applying it a number can cut into many equal parts. It is opposite to multiplication.
As 60 books occupy 1.4 m of shelf ,
S0, 1 books occupies = 1.4/60 m of shelf
Then, 300 books occupy {(1.4/60)×300} m of shelf=
7m of shelf
Now, 7m=700cm is occupied by 300 books,
So,1cm is occupied by (300/700) books
Then, 84cm is occupied by (300/700)×84 books=36 books.

A math test is worth 100 points. There are a total of 26 questions. There are equation questions that are worth 2 points each and vocabulary questions are 5 points each. Use a system of equations to solve for the number of equation questions and vocabulary questions on the math test.
Answer:
Let the number of equations be x and the number of vocabulary questions be y.
x + y = 26 (total num of questions)So, y = 26 - x (eliminate one variable to solve for one first)2x + 5y = 100 (total points)2x + 5 (26 - x) = 100 (substituting 26 - x in place of y)
2x + 130 - 5x = 100 (distributing the 5)-3x = -30x = 10
Since there are 10 equation questions, there must be 16 vocabulary questions to satisfy the total number of questions in the test

Susan is using 0.5 acres of land for organic farming.
If she divides the land into 6 equal-sized plots for the
6 vegetables she is planting, what will be the size of
each plot? (1 acre = 43,560 square feet)
A) 3,630 square feet
B) 6,700 square feet
C)
7,260 square feet
D) 14,520 square feet
The size of each plot is 3630 square feet to plant six vegetables.
Given, Susan is using 0.5 acres of land.
we know that 1 acre = 43,560 square feet
0.5 acre = 1/2 acre = 1/2 × 43,560
= 21780 square feet.
we need to divide the land into 6 equal sized plots.
divide 21780 into six equal parts.
= 21780/6
= 3630 square feet
the land is being divided into 3630 square feet to plant 6 equal sized plots.
Hence susan plants six vegetables in 3630 square feet each.

Explain how you can tell if y=ab x represents exponential growth or exponential decay.
In the form y = ab^x, if b is a number between 0 and 1, the function represents exponential decay.
The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.
Radioactive decay and population decline are two examples of exponential decay. The data collected can be used to forecast future population trends for cities and colonies as well as the half-life of radioactive materials.

Written as a simplified polynomial in standard form, what is the result when (3x-3)^2 is subtarcted from 4xr^2
The resulting polynomial after subtracting will be -5x² +18x -9
In the given question, we have two polynomials. We have to Subtract (3x-3)² from 4x². Firstly we will have to calculate (3x-3)².
Calculating, (3x-3)²
=> (3x - 3)² = 9x² -18x +9
After evaluating (3x - 3)² we get 9x² -18x +9.
Subtracting 4x² by 9x² -18x +9 we get:
=> 4x² - (9x² -18x +9) => 4x² - 9x² +18x -9
=> -5x² + 18x -9
We get a resultant answer after subtracting -5x² + 18x -9
Hence, the equation after subtracting the two numbers will be
-5x² + 18x -9

How to calculate the percentage ?The First step is to calculate the percentage of men in attendance
There are 75 men and 60 women
Total number of people in attendance= 75 +60
= 135
75/135 × 100
= 0.556 × 100
= 55.6
The percentage of women in attendance
= 60/135 × 100
= 0.444 × 100
= 44.4
Next step is to subtract both percentages
= 55.6 - 44.4

Answer to this question is:
Domain of given function is (-∞,∞),{x|x∈R}
Range of given function is [0,∞),{y|y≥0}
Inverse of given function is √2x,-√2x
The domain is all values of x that make the expression defined.The entire range of independent variable values is the domain of a function.
This definition can be stated simply as follows: The domain is the collection of all x-values that can be used to make the function "work" and produce actual y-values.
When choosing the domain, keep in mind that a fraction's denominator (bottom) cannot be 0.
Interval Notation:(-∞,∞)

A ball is thrown upward and outward from a height of 5 feet. The height of the ball, y, in feet, can be modeled by y=-0.4x^2+1.6x+5 where x is the ball's horizontal distance, in feet, from where it was thrown.
a. What is the maximum height of the ball and how far from where it was thrown does this occur?
b. How far does the ball travel horizontally before hitting the ground?
c. Graph the equation that models the ball's parabolic path.
The maximum height of the ball is 9.8 feet.
The distance the ball travels horizontally before hitting the ground is 2.
The graph that model the parabolic path is given below.
What is a parabolic path?Parabolic path is defined as the angle of trajectory of a projectile.
We have,
y = 0.4x² + 1.6x + 5 _____(1)
Where,
x = balls horizontal distance
y = height of the ball
To find the maximum height we need to differentiate y and set y = 0.
y' = 0
0.4 x (2x) + 1.6 + 0 = 0
0.8x + 1.6 = 0
-0.8x = -1.6
x = 1.6 / 0.8
x = 2
Now the maximum height of the ball is:
Put x = 2 in (1)
y = -0.4 x (2)² + 1.6 x (2) + 5
y = 0.4 x 4 + 3.2 + 5
y = 1.6 + 3.2 + 5
y = 9.8
The distance the ball travels horizontally before hitting the ground:
x = 2
The equation that models the ball's parabolic path is given below:
Thus,
The maximum height of the ball is 9.8 feet.
The distance the ball travels horizontally before hitting the ground is 2.

Find the amount in a continuously compounded account for the given conditions.principal: $ 950 annual interest rate: 6.5% time: 10 years
The amount in a continuously compounded account for the given conditions is $1819.76 .
Compound interest is interest calculated on the principal and the interest accrued in previous periods. Compound interest is interest based on principal and interest accumulated over a period of time.If we specifically state that the quantity in question is "continuously composed", we must use the continuous constitutive formula which is given by [tex]A=Pe^{rt}[/tex] ..... (1) where, P = initial amount , A = final amount , r = interest rate , t = time , e is a mathematical constant with e ≈ 2.7183.

Putting [tex]P=\$950 , \ r= 6.5\% , \ t=10 \ years[/tex] in equation (1) , we get
