What is the formula of base?
Names and Formulas of Bases Table 7.13.1 Formula Name NaOH sodium hydroxide Ca(OH)2 calcium hydroxide NH4OH ammonium hydroxide.
How do you find the missing height of a triangle?
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!.
How do you find the base of a triangle with the hypotenuse and height?
For example, to find the area of a right triangle with a height of 4 cm and hypotenuse 5 cm, we first find its base using the Pythagoras theorem. Then we get, base = √[(hypotenuse)2 – (height)2] = √(52 – 42) = √9 = 3 cm.
What are the example of base?
Examples of bases are sodium hydroxide, calcium carbonate and potassium oxide. A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts.
What are the 10 examples of base?
Strong Arrhenius Bases Potassium hydroxide (KOH) Sodium hydroxide (NaOH) Barium hydroxide (Ba(OH) 2 ) Caesium hydroxide (CsOH) Strontium hydroxide (Sr(OH) 2 ) Calcium hydroxide (Ca(OH) 2 ) Lithium hydroxide (LiOH) Rubidium hydroxide (RbOH).
What is base triangle?
Answer: The bottom line of a triangle is the base of the triangle, and it can be one of the three sides of the triangle. In a triangle, one side is a base side and the remaining two sides can be the height or the hypotenuse side.
How do you calculate height?
To get your height in inches alone from the way it’s usually presented (e.g. 5′ 7″), multiply the total number of feet by 12 and then add the remainder. For example, a 5′ 7″ person is (5 × 12) + 7 = 67″ tall. To convert inches to centimeters (in to cm), simply multiply by 2.54.
Is base same as altitude?
Altitudes are line segments that stretch from a corner (a.k.a. vertex) to the opposite side (a.k.a. base), making a right angle with the base. Altitudes are always perpendicular to their base.
How do you find the base of a triangle using the Pythagorean Theorem?
The Pythagorean Theorem is essentially, a2 + b2 = c2. Add side a times itself to side b times itself to arrive at the length of the hypotenuse, or side c times itself.
What is the base dimension of a triangle?
Vocabulary Language: English ▼ English Term Definition Triangle A triangle is a polygon with three sides and three angles. Area of a Parallelogram The area of a parallelogram is equal to the base multiplied by the height: A = bh. The height of a parallelogram is always perpendicular to the base (the sides are not the height).
Is the base of a triangle the hypotenuse?
The hypotenuse is related to the base and the altitude of the triangle, by the formula: Hypotenuse2 = Base2 + Altitude2. The base and the altitude are the arms of the right angle, and the hypotenuse is the side opposite to the right angle, in a right-angled triangle.
How do you find the base of a power?
Base (of a Power) The base of a power is the factor that is repeatedly multiplied by itself. 24 = 2 x 2 x 2 x 2. 24 = (2)(2)(2)(2).
Is NaOH a base?
Now let’s look at lye, a strong base with the chemical formula NaOH (sodium hydroxide). If we add NaOH to water, it dissociates into Na+ and OH–. The sodiums don’t do anything important, but the hydroxyls make the solution more basic.
What is a base write down the name and formula of four bases?
Since they all contain the OH– anion, names of bases end in hydroxide. The cation is simply named first. Some examples of names and formulas for bases are shown in the Table below.Names and Formulas of Bases. Formula Name NaOH sodium hydroxide Ca(OH) 2 calcium hydroxide NH 4 OH ammonium hydroxide.
What type of nomenclature would you use for NaOH?
nomenclature of ionic compounds …the compound NaOH is called sodium hydroxide, because it contains the Na+ (sodium) cation and the OH− (hydroxide) anion.
What is the base math?
Base, in math, is defined as a set of digits used to represent numbers. Different number systems use different combinations of digits as the base. The most common number system that we use is the decimal number system that uses the base 10, which includes digits from 0 to 9 for writing numbers.
What are 20 examples of bases?
Arrhenius Bases Drain cleaner. Laundry detergent. Lubricating grease. Alkaline batteries. Soaps and bath products. Sugar. Baking soda.
What is the base in a math expression?
An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.
What are the 3 types of bases?
On the basis of acidity bases can be classified into three types: monoacidic, diacidic and triacidic.
Is shampoo a base?
But the main ingredient in shampoo is citric acid. Based on the pH of citric acid, the pH of shampoo can be determined. Shampoo is a basic hair care product. The pH of a shampoo never falls on basic compounds i.e., above the value of 7 as the alkaline shampoo can have a severe effect on hair.
How many bases does triangle have?
The altitude of a triangle is the perpendicular from the base to the opposite vertex. (The base may need to be extended). Since there are three possible bases, there are also three possible altitudes. The three altitudes intersect at a single point, called the orthocenter of the triangle.
Which side is the height of a triangle?
The height of a triangle is the distance from the base to the highest point, and in a right triangle that will be found by the side adjoining the base at a right angle. So if the base is , then and vise versa.
What is the formula of area?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).
Is altitude the same as height in a triangle?
In a triangle, a line segment from a vertex and perpendicular to the opposite side is called an altitude. It is also called the height of a triangle. If the triangle is obtuse, then the altitude will be outside of the triangle.
