Answer:

84,375 m^2

Step-by-step explanation:

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).

Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.

Area of a square is length times width.

Total area = $4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2$

Identify the properties used in Step 1 and Step 2 to solve the equation shown. Then discuss why those properties were used. Prob

<h3>Step-by-step explanation:</h3>

<u>Step</u> <u>Property</u>

2x+6 = 22 given

2x = 16 addition property of equality (-6 added to both sides)

x = 8 multiplication property of equality (both sides × 1/2)

_____

In general equations are solved by reversing the steps done to the variable. Here, the variable (x) is multiplied by 2 and 6 is added to that product. So, to find x, we undo the addition of 6 (by adding -6, the additive inverse), and undo the multiplication by 2 (by multiplying by 1/2, the multiplicative inverse).

If other functions were performed on the variable in the original equation, their inverse functions would be used, too, as part of the solution process.

How to write 3 9/100 as a decimal?

Artemon [7]

3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.

Given that r||s and q is a transversal, we know that by the [________]. corresponding angles theorem alternate interior angles t

neonofarm [45]

Answer:

alternate interior angles theorem

Step-by-step explanation:

The alternate interior angles theorem states that when two parallel lines are cut by a transversal, the resulting angles produced are a pair of congruent alternate interior angles.

Given the image attached below, both line k and line l are parallel to each other and also, line t is the transversal, therefore the resulting congruent alternate interior angles produced are:

∠ 4 ≅ ∠6, ∠1 ≅ ∠7
