A square pyramid has a height of 25 ft and each side of the base has a length of 15 ft.

Naya [18.7K]

Answer:

Surface area of square pyramid is computed as follows:

A = a² + a*√(a² + 4h²)

where <em>a</em> is the base length and <em>h</em> is the height.

If a model of the square pyramid is scaled down by a factor of x, then the surface area will be:

A' = (a/x)² + (a/x)*√[(a/x)² + 4(h/x)²]

A' = a²/x² + a/x * √[a²/x² + 4h²/x²]

A' = a²/x² + a/x * √[(a² + 4h²)/x²]

A' = a²/x² + a/x * √(a² + 4h²)/√x²

A' = a²/x² + a/x² * √(a² + 4h²)

A' = 1/x² * [a² + a*√(a² + 4h²)]

A' = 1/x² * A

That is, the surface area will be 1/x² times the original surface area. If h = 25 ft and a = 15 ft:

A = 15² + 15*√(15² + 4(25)²) = 1008.02 ft²

The factor is not mentioned in the question, nevertheless, the area will be 1008.02/factor² ft²

Hadley has a 1/2 kg of popcorn she divides the popcorn into three equal bags how many kilograms of popcorn with each bag

Cerrena [4.2K]

$\frac{1}{2} / \frac{3}{1} = \frac{1}{2} * \frac{1}{3} = \frac{1}{6}$
So each bag will contain 1/6 kilogram of popcorn

PLS HELP ILL GIVE BRAINLIST!

RideAnS [48]

Answer:

The length of AP will be 14 units.

Step-by-step explanation:

As P is the centroid of ΔABC as shown in question figure.

As the side AB of the triangle has the midpoint D, the side AC of the triangle has the midpoint F and the side BC of the triangle has the

midpoint E.

Hence, CD, BF and AE being medians of ΔABC.

The point of intersection of these medians will be the centroid of the triangle. Hence, P is the centroid of ΔABC

According to rule, the centroid point of the triangle ΔABC divides each median into two segments in the ratio 2 : 1.

So,

$AP = \frac{2}{3} AE$

As the value of AE = 21

So,

$AP = \frac{2}{3} (21)$

AP = 14

So, the length of AP will be 14 units.
