Equilateral triangle means that all sides are equal in length. When it is asked for a height of equilateral triangle it refers to vertical distance from highest point of the triangle to the lowest(Right in the middle). So we got two known and one unknown which tells us that we can use Pythagorean Theorem C2=A2 + B2

A=4

B=?

C=8

Solve for B and you will get answer Square root of 48.

Well, darling, 7000 meters is the same as 7 kilometers. It's like asking how many inches in a foot - there are 12. So, in this case, you've got yourself a nice round 7 kilometers. Hope that clears things up for you, honey.

One trillion. "One" represents the number 1, and "trillion" denotes a numerical value equal to 1 followed by 12 zeros. The prefix "tri-" signifies three zeros, and the suffix "-illion" signifies a power of one million. Therefore, 1,000,000,000,000 can be read as one trillion.

No, a reflex angle and an obtuse angle are not the same. An obtuse angle is an angle that measures between 90 and 180 degrees, while a reflex angle measures greater than 180 degrees but less than 360 degrees. In other words, a reflex angle is larger than a straight angle (180 degrees) but smaller than a full rotation (360 degrees).

10 to the 18th power is equal to 10,000,000,000,000,000,000. This is because when you raise 10 to the 18th power, you are multiplying 10 by itself 18 times. Each time you multiply, you add a zero to the end of the number, resulting in a total of 18 zeros at the end.

The formula would be: X(X+1)=6162.

X^2+X = 6162.

X^2+X-6162 = 0; Factor this.

(X+79)(X-78)=0.

X+79=0 or X=-79; impossible.

X-78=0; X=78; first page.

Second page X+1=79.

Therefore page numbers are 78 & 79.

Check: 78*79=6162.

Oh, dude, a polygon with two sides? That's like trying to find a unicorn at a petting zoo. A polygon, by definition, has straight sides, and you can't really have a shape with just two straight sides. It's like asking for a square with only one corner - it just doesn't exist in the world of shapes.

To convert 111 over 200 to a decimal, you simply divide the numerator (111) by the denominator (200). This division would result in 0.555. Therefore, 111 over 200 as a decimal is 0.555.

Neither. All irrational numbers are real numbers.
Using the real number system you can't take the square root of a negative number, but if you're dealing with imaginary numbers then the square root of negative 3 is the square root of 3i

Yes, .625 is greater than 0. When comparing decimals, you can look at the digits to the left of the decimal point to determine which number is greater. In this case, .625 has a digit to the left of the decimal point (6), while 0 does not. Therefore, .625 is greater than 0.

Well, darling, the circumference of a circle is calculated using the formula C = 2πr. So, with a radius of 21 cm, you just plug that bad boy in and get C = 2 x π x 21 = 132 cm. Voilà, there you have it!

To determine which is greater between the square root of 3 and the square root of 7, we can compare their values. The square root of 3 is approximately 1.732, while the square root of 7 is approximately 2.646. Therefore, the square root of 7 is greater than the square root of 3.

Let the first integer be x. The second consecutive integer would then be x+1. The sum of these two integers is x + (x+1) = 15. Simplifying, we get 2x + 1 = 15. Solving for x, we find that x = 7. Therefore, the two consecutive integers are 7 and 8.

Ah, what a happy little math question we have here! To find the reciprocal of 0.25, you simply flip the number over. So, the reciprocal of 0.25 is 1 divided by 0.25, which equals 4. Keep practicing your math skills, and remember, there are no mistakes, just happy little accidents!

Oh honey, without the Order of Operations, you're just asking for a hot mess. Trying to solve complex math problems without following the correct order of operations is like trying to bake a cake without a recipe - you're gonna end up with a disaster. So, technically speaking, any math problem becomes a nightmare without those rules in place.

yes by a factor of ten. 0.10 is ten times greater than 0.01

Oh, what a happy little question! When you multiply 10 meters by 8 meters, you get 80 square meters. That's a nice, big area to work with! Just imagine all the beautiful paintings you could create in a space like that.

To divide an octagon into thirds, you would first need to draw lines from each vertex (corner) to the opposite vertex, creating four smaller triangles within the octagon. Next, draw a line connecting the midpoints of two opposite sides of the octagon, creating a line of symmetry. This line will divide the octagon into two equal parts. Finally, draw another line parallel to the first line of symmetry, but one-third of the way from the first line to the opposite side of the octagon. This will divide the octagon into three equal parts, each representing one-third of the total area.

To calculate 0.4 multiplied by 10, you simply move the decimal point of 0.4 one place to the right, resulting in 4. Therefore, 0.4 x 10 equals 4.

0.3333

In binary code, each digit represents a power of 2, starting from the right with 2^0. The binary number 011010 is equivalent to 26 in decimal form. This can be calculated by adding the decimal values of the positions where a '1' appears in the binary number: 2^5 + 2^3 + 2^2 = 32 + 8 + 4 = 26.
