Answer:
A = 400 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the vertical height ) , then
A = × 20 × 40 = 10 × 40 = 400 ft²
Sara purchased a porcelain sculpture that is in the shape of a square pyramid. The slant height is 6.1 inches and the base 6.4 i
1 answer:
The surface area of the square pyramid will be 78.08 square inches.
<h3>What is surface area?</h3>The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
<h3 />Given that:-
Sara purchased a porcelain sculpture that is in the shape of a square pyramid. The slant height is 6.1 inches and the base is 6.4 inches. The surface area will be.
The surface area of the square pyramid will be calculated by the formula:-
SA = 78.08 square inches
Therefore the surface area of the square pyramid will be 78.08 square inches.

Answer:
Step-by-step explanation:
Starting from the y-intercept of you do
by either moving one block <em>south</em> over one block <em>west</em> or one block <em>north</em> over one block <em>east</em> [<em>west</em> and <em>south</em> are negatives].
Now, for Line <em>A</em>, we need to convert this <em>Linear</em><em> </em>Standard Equation to Slope-Intercept Form, where the slope is represented by <em>m</em>:
x + y = 3
- x - x
__________
So, the slope of Line <em>A</em> is and since −1 is less than 1, <em>less than</em> would be the answer, HOWEVER, they BOTH have some slope of 1, so since −1 is the negative <em>absolute</em><em> </em><em>value</em><em> </em>of 1, <em>equal</em><em> </em><em>to</em><em> </em>will be the answer.
