what is integer array in c ?
In C programming, an integer array is a collection of integer values identified by a unique index within the array.
In C programming language, a whole number exhibit is an information structure that holds a grouping of number qualities. A cluster is an assortment of components of similar information type, where every component is recognized by a one of a kind record or position inside the exhibit. Number exhibits in C are proclaimed utilizing a particular language structure, which incorporates the information type and the size of the exhibit. For instance, to pronounce a number cluster with ten components, you can utilize the accompanying linguistic structure:
int myArray[10];
Once announced, you can get to individual components of the cluster utilizing their record, what begins from 0. For instance, to dole out a worth of 5 to the main component of the exhibit, you can utilize the accompanying sentence structure:
myArray[0] = 5;
In general, whole number exhibits are a helpful device in C programming for putting away and controlling assortments of number qualities.

What is 86 Inches in Feet?
86 inches are equivalent to 7.17 feet
To convert inches to feet, you can divide the number of inches by 12 (since there are 12 inches in a foot):
86 inches ÷ 12 inches/foot = 7.17 feet
The units of measurement used to measure length or distance are inches and feet. One inch is equivalent to one-twelfth of a foot, while one foot is equal to twelve inches. As a result, you may easily convert feet to inches by multiplying the number of feet by 12. 36 inches, for instance, is equivalent to 3 feet (3 feet x 12 inches/foot).
Divide the number of inches by 12 to convert the measurement to feet. As an illustration, 24 inches (12 inches per foot) equals 2 feet.
Inches and feet are often used to measure an object's height, breadth, and length in the United States.

35 out of 56 students want pancakes and the rest want waffles. What is the ratio of the number of students who want waffles to the total number of students?
Answer: Waffles: Total Number of Students is 21:56. Simplified it would be 3:8.
Step-by-step explanation:
First, you take the total number of students, which in this case is 56, and subtract it from the number of students who want the pancakes. The difference is 21. That is the number of students who want waffles.
The ratio is 21:56. It must be in that order. It is not the Total number of students: waffles, it is waffles: total number of students.
If it must be simplified, find the greatest common factor. In this problem, it is 7. So the simplified version is 3:8.

Step-by-step explanation:
This composite heart shape consists of two semi-circles and a rectangle.

What is Scale factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
Given:
The current space is rectangular and has a length of 24 feet and a width of 26 feet.
and, the new space is 36 feet long.
let the width of new space is x.
Since, the two space are similar then the scale factor will be

Linda plans to sign up for three field events. She wants to run a total of more than a kilometer but less than 1.5 kilometers which three events should she sign up for?
Linda can choose any combination of three events that adds up to more than a kilometer but less than 1.5 kilometers
In order to find the best combination of events for Linda to sign up for to run a total of more than a kilometer but less than 1.5 kilometers, we must first determine the total distances of the individual events.
Depending on the events offered, Linda can choose three events that add up to more than a kilometer but less than 1.5 kilometers.
If Linda has the option of running the 100m, 200m, and 800m, she can satisfy her requirement of running more than a kilometer but less than 1.5 kilometers by choosing the 100m, 200m, and 800m.
This would add up to 1100m, which is slightly over a kilometer but below 1.5 kilometers.

A relative frequency distribution for quantitative data identifies the proportion of observations that occur in each bin.
Relative frequency distribution is a type of frequency distribution that shows the proportion or percentage of observations that fall into each bin or class interval. It is calculated by dividing the frequency of each bin by the total number of observations. This allows us to compare the relative frequencies of different bins, and see how the data is distributed across the range of values.
For example, if we have 100 observations and 20 of them fall into the first bin, the relative frequency of the first bin would be 20/100 = 0.2 or 20%. This means that 20% of the observations fall into the first bin.
In summary, a relative frequency distribution for quantitative data identifies the proportion of observations that occur in each bin, allowing us to compare the relative frequencies of different bins and see how the data is distributed across the range of values.

What is the Trigonometry ?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles, and the trigonometric functions that describe those relationships.
We can use the identity sin²θ + cos²θ = 1 to find sinθ, since we know cosθ:
sin²θ + cos²θ = 1
sin²θ + 0.2² = 1 (substituting cosθ = 0.2)
sin²θ = 0.96
Taking the square root of both sides, we get:
sinθ = ± 0.9798
Since θ is in the second quadrant, sinθ is negative.

How do you know if a quadratic equation can be solved by factoring?
A quadratic equation can be solved by factoring if its coefficients are rational numbers and its discriminant, which is the expression under the square root in the quadratic formula, is a perfect square.
To determine if a quadratic equation can be solved by factoring, you must first ensure that its coefficients are rational numbers, meaning that they can be expressed as a ratio of two integers. Once you have confirmed this, you can calculate the discriminant of the quadratic equation, which is the expression b²-4ac, where a, b, and c are the coefficients of the quadratic equation in standard form.
If the discriminant is a perfect square, then the quadratic equation can be solved by factoring. If the discriminant is not a perfect square, then the quadratic equation cannot be solved by factoring using rational numbers, but may still be solvable using other methods, such as completing the square or the quadratic formula.

how much is 14 km to miles
14 kilometers is approximately equal to 8.699 miles
The conversion factor from kilometers to miles is 0.621371.
The conversion is the process of changing the unit of one quantity to another units
The conversion factor is defined as the number that is used to change one unit to another units by multiplying or dividing
So, to convert kilometers to miles you can multiply the number of kilometers by 0.621371.
The distance in kilometer = 14 kilometers
The distance in miles = conversion factor × The distance in kilometer
Substitute the values in the equation
The distance in miles = 14 × 0.621371
Multiply the numbers

Jose invests money in an account paying a simple interest of 9% per year, he should multiply his current balance by 9% to find his total balance.
Simple Interest is a simple way for computing interest on a loan or principle amount. The notion of simple interest is used in many sectors, including banking, finance, and vehicles. The monthly interest is deducted first, followed by the principal amount, when you make a loan payment.
We have rate of interest as 9%
So, SI = PNR/100
SI = P x 1 x 9/100
SI = P x 9%.
Therefore, current balance should be multiplied by 9% .
Simple Interest (S.I.) is a way of determining the amount of interest for a given principle amount. You put that money to use for the reason you borrowed it in the first place. The money is then returned after you receive your following month's pocket money from your parents. This is how borrowing and lending operate in the real world.
