Find cosec 60°, sec 60°, and cot 60°
To find cosec 60°, sec 60°, and cot 60°, we first need to understand the basic properties of these trigonometric functions. 1. cosec 60°: The cosecant function is the reciprocal of the sine function. Therefore, cosec 60° = 1/sin 60°. Since sin 60° is √3/2, we have: cosec 60° = 1/(√3/2) = 2/√3 = (2√3)/3. […]
Which of the following is the smallest unit of measurement?
The smallest unit of measurement is the Planck length, which is approximately 1.616 x 10-35 meters. To put it in perspective, the Planck length is many orders of magnitude smaller than subatomic particles, making it the theoretical lower limit of length in the universe. However, it’s important to note that in different contexts, we often […]
If a theater holds 1800 people and sells 1/3 of its seats, how many tickets does it sell?
To find out how many tickets the theater sells, we need to calculate one-third of the total number of seats available. The theater has a total capacity of 1800 seats. The calculation to find one-third of the seats is: 1800 × (1/3) = 600 Thus, the theater sells a total of 600 tickets. This means […]
What is 135 as a mixed number?
To express 135 as a mixed number, we first need to understand what a mixed number is. A mixed number consists of a whole number and a proper fraction. In this case, since 135 is already a whole number, we can express it as a mixed number by incorporating a fraction of 0. Therefore, 135 […]
How to Calculate the Surface Area of a Square Pyramid?
The surface area of a square pyramid can be calculated using the formula: Surface Area = Base Area + Lateral Area Where: Base Area is the area of the square base. Lateral Area is the total area of the four triangular faces. To break it down further: 1. **Calculate the Base Area**: The base of […]
Is 2020 a Leap Year?
Yes, 2020 is indeed a leap year. Leap years are determined by a specific set of rules established in the Gregorian calendar. To be classified as a leap year, a year must be divisible by 4. However, if the year is divisible by 100, it must also be divisible by 400 to qualify as a […]
What is the difference between an outcome and an event?
An outcome and an event are terms that are often used in various fields, such as statistics, probability, and even everyday conversation, but they do refer to different concepts. An event is a specific occurrence that can be observed. It can refer to anything that happens within a given context. For instance, in a game […]
What is 15% of 500?
To find 15% of 500, you can use a simple calculation method. First, convert 15% into a decimal. You do this by dividing 15 by 100, which gives you 0.15. Next, multiply this decimal by 500: 0.15 x 500 = 75 So, 15% of 500 is 75. This means that if you were to take […]
How Many Lakhs Make a Million?
In the context of the Indian numbering system, one lakh is equal to one hundred thousand. Therefore, to find out how many lakhs make a million (which is one thousand thousand), we can use simple division. 1 million is equal to 10 lakhs because: 1 lakh = 100,000 1 million = 1,000,000 So, when you […]
How to Find the Equation of a Line Given a Slope and a Point?
To find the equation of a line with a given slope and a specific point, we can use the point-slope form of the equation of a line. The point-slope form is expressed as: y – y1 = m(x – x1) Where: m is the slope of the line. (x1, y1) is the given point that […]
