How many days would it take to complete the building?A fraction is a non-integer that has a numerator and a denominator. The numerator is the number above. While the denominator is the number below. An example of a fraction is 1/4.
A mixed number is a number that has a whole number and a proper fraction. A proper fraction is a non-integer in which the numerator is less than the denominator. An example of a mixed number is 3 1/2.
The first step is to determine the total height of the office bulding = height of each floor x total number of floors
15 x 10 2/5
15 x 52/5 = 780 /5 = 156
The next step is to determine the floors left to complete the office building :
156 - 24 9/10 = 131 1/10 feet
The last step is to divide the feet that can be built each day by the number of floors needed to complete the builfing :
1311/10 ÷ 1 1/4
1311 / 110 ÷ 5/4
1311 / 10 x 4/5 = 104 days 44/50

differenciate the Function 1/ X3
Answers
Step-by-step explanation:
To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:
Write the function: f(x) = 1/x^3.
Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).
Differentiate the function: In our case, n = -3, so the derivative is:
f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.
Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

Answers
Answer:
a
Step-by-step explanation:
Answer:
The inequality representation is : x + y ≥ $400
Step-by-step explanation:
Inequality is the comparison and boundary for two non equal values. So inequality compares the non equal values.
As the owner wants to make $400 and sets boundary that;
Least amount to make = $400
Highest amount to make= infinite
This introduces relation in inequality as $400 or greater than $400.
The money made is counted combine from child tickets and adult tickets. If x is the made made through child tickets and y is from the adult then,
x + y ≥ $400

The rear windshield wiper blade on a car has a length of 11 inches. The blade is mounted on a 15 inch arm, 4 inches from the pivot point. Of the wiper turns through an angle of 135 degrees, how much area is swept clean?
Answers
Answer:
\(246.22\ \text{inches}^2\)
Step-by-step explanation:
\(r_1\) = Radius of arm = 15 inch
Length of blade = 11 inches
\(r_2\) = Radius of point at which the blade is mounted = 4 inches
\(\theta\) = Angle of the sector = \(135^{\circ}\)
The required area is ABDE
\(ABDE=ACE-BCD\\\Rightarrow ABDE=\dfrac{\theta}{360^{\circ}}\pi r_1^2-\dfrac{\theta}{360^{\circ}}\pi r_2^2\\\Rightarrow ABDE=\dfrac{\theta}{360^{\circ}}\pi(r_1^2-r_2^2)\\\Rightarrow ABDE=\dfrac{135^{\circ}}{360^{\circ}}\pi(15^2-4^2)\\\Rightarrow ABDE=246.22\ \text{inches}^2\)
The area which is swept clean is \(246.22\ \text{inches}^2\)

The modular inverse of 73 modulo 660 is 1
How to find an inverse for 73 modulo 660?To find an inverse for 73 modulo 660, you can use the extended Euclidean algorithm. This is an algorithm that allows you to find the modular inverse of a number if it exists.
Here is how to use the extended Euclidean algorithm to find the inverse of 73 modulo 660:
1. Set a = 660 and b = 73
2. Calculate the remainder of a divided by b, which is r = a % b = 660 % 73 = 37
3. If r is 0, then b is the modular inverse of a modulo 660. In this case, 73 is not the modular inverse, so we proceed to the next step.
4. Set a = b and b = r. Calculate the remainder of a divided by b, which is r = a % b = 73 % 37 = 36.
5. If r is 0, then b is the modular inverse of a modulo 660. In this case, 37 is not the modular inverse, so we proceed to the next step.
6. Set a = b and b = r. Calculate the remainder of a divided by b, which is r = a % b = 37 % 36 = 1.
7. If r is 0, then b is the modular inverse of a modulo 660. In this case, r is not 0, but we have reached the end of the algorithm because we have found a remainder of 1.
8. To find the modular inverse of 73 modulo 660, we need to backtrack through the previous steps and use the remainders to calculate the modular inverse using the formula:
modular inverse = b^(p-2) mod p
where b is the number for which we are trying to find the modular inverse, and p is the modulus.
Substituting in the values from the previous steps, we get:
modular inverse = 1^(660-2) mod 660 = 1^658 mod 660 = 1
Therefore, the modular inverse of 73 modulo 660 is 1. This means that 73×1 = 73 mod 660.

Using an algebraic equation to represent the word problem, the smallest integer is 1
Word ProblemThis is a way of representing mathematical problems with words. To solve this, we have to use algebraic equations or expressions.
Let the integers be represented as
xx + 2x + 4We can write an equation from the word problem given as
7 × (x + 2) = 15 + [x + (x + 4)]
7x + 14 = 15 + x + x + 4
7x + 14 = 15 + 2x + 4
collect like terms
7x - 2x = 15 - 14 + 4
5x = 5

To solve this equation, use PEMDAS:
P - Parentheses
E - Exponents
M/D - Multiplication/Division
A/S - Addition/Subtraction
PEMDAS is the method that is used for the order of operations. Multiplication and division are interchangeable, so when there are only those signs left, you solve from left to right. This also applies to addition and subtraction.
Equations must always be solved in the order of PEMDAS -- P, then E, then M/D, then A/S.
Now, to solve the equation:
100 - 2(12 + 13) First, solve what is in the parentheses (P).
100 - 2(25) Next, multiply 2 × 25 (M).
100 - 50 Finally, subtract 50 from 100 (S)

100 - 2(12 + 13) = 50

The height of the largest photo is 16 inches.
Sydney's senior picture package includes several sizes of portraits. The smallest photo is a 1.5-inch wide and 2 inch tall rectangle.
The largest photo is 12 inches wide and is similar to the smallest photo.
Let's assume that the largest photo's height is h, then we can say the ratio of the largest photo to the smallest photo is given as:\[\frac{h}{2}=\frac{12}{1.5}\]
Simplify the ratio:\[\frac{h}{2}=8\]
Multiplying each side by 2:\[h = 16\]
Therefore, the height of the largest photo is 16 inches.
Hence, the answer is 16.
