5 bases. It depends on which face is used as the base.

Generally it would be the rectangular face is the base.

However, re-orientating the pyramid , a triangular face could be the base , and the rectangle one of the faces ( in the air).

This equation is qritten as

n/5 = 27

Multiply both sides by '5'

n = 135

There is NO answer!!!

It is a mathematical expression, NOT an equation.

Algebraically it is written as ' n/5 '.

Biology , Chemistry. are the primary subjects. Good secondary subjects are Physics and Mathematics.

None!!!!

However, if the square is intersected by two diagonal lines, then eight(8) internal triangles can be found.

A pyramid!!!!

The base is a square. Each angle forming the base is 90 degrees.

The four faces can each be equilateral triangles. Each triangular angle being 60 degrees.

The base length and the triangular edges are all the same length.

A SQUARE PYRAMID .

Or more correctly , just a PYRAMID., because all pyramids have square bases.

NB A triangular based pyramid is more correctly named a TETRAHEDRON. As it is only a solid onject of four faces. viz., 1 base and three faces.

Small correction to the answer above: it's 72 bags, not 54. The math: 1 cubic yard = 27 cubic feet, and a 50 lb bag yields 0.375 cubic feet. 27 ÷ 0.375 = 72 bags exactly. (The 54 figure comes from dividing by 0.5 cu ft per bag, which isn't the 50 lb yield.)

Hand-mixing 72 bags is brutal, by the way — anything near a full yard is usually worth ordering as ready-mix instead of bags. If you want the full yield table for all bag sizes (40/50/60/80 lb), this bag guide lays it out clearly: concretecalcus . com / bags

0.5

Yes, 0.09 is a rational number because it can be expressed as a fraction. Specifically, it can be written as 9/100, where both the numerator and the denominator are integers. Rational numbers are defined as numbers that can be expressed in the form of a/b, where a and b are integers and b is not zero. Thus, 0.09 fits this definition.

200k in numbers is written as 200,000. The "k" stands for "thousand," so 200k means 200 times 1,000. Thus, when converted to standard numerical form, it equals two hundred thousand.

One penny is equal to 1 cent.

Slightly longer than 1 inch.

Remember 1 inch = 2.54cm

A square number is an integer that is the square of another integer (ie 9 is a square number because it is the square of 3).

The square root of 515 is 22.6936...etc , and therefore cannot be a square number

The right angle (90 degree angle).

If you are 19 years old, you are typically in college or university, as most students graduate high school around age 18. However, some may still be in their final year of high school if they started school late or have repeated a grade. In some cases, individuals may take a gap year, so their educational status can vary.

A circle prism is called a circular prism not a cylinder

In the number 756, the place value of 7 is 700. This is because the 7 is in the hundreds place, which represents 7 times 100. Therefore, the place value of 7 contributes significantly to the overall value of the number.

Infinitely many. There are a 100 perfect squares.

NO!!!

Because it is an equation, because it contains an 'equals(=)'.

A mathematical expression does NOT contain an 'wquals'.
