Answer:
$144
Step-by-step explanation:
Volume of the pyramid = 1/3BH
Base area B = 1/2 * 6 * 4
Base area B = 12 ft²
Height H = 4ft
Volume of the pyramid = 12 * 4
Volume of the pyramid = 48ft³
SInce 1 ft³ = $3
48ft³ = x
Cross multiply
x = 3 * 48
x = 144
Hence the cost of the sign is $144
Answer:
A
Step-by-step explanation:
for a right angled triangle, the sum of the square of the two sides should be equal to the square of the hypotenuse. If this rule does not hold, the dimensions do not represent the side of a right angled triangle.
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
4² + 10² ≠ 16²
6² + 12² = 13²
7² + 24² = 25²
8² + 15² = 17²
