Step-by-step explanation:
Answer: The numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
Step-by-step explanation:
The numbers on a number line are from - infinity to + infinity whose center is at 0.Om left sides of 0 , there are negative integers and on the right side there are positive integers.
So, The numbers on a distance of 3.2 units from −4 on a number line are
-4 - 3.2 and -4+3.2
= - (4+3.2) and - (4-3.2)
= -7.2 and - 0.8
Hence, the numbers on a distance of 3.2 units from −4 on a number line are -7.2 and - 0.8 .
Answer:
62m³
Step-by-step explanation:
The question is incomplete. Find the diagram of the prism attached below.
Volume of a Prism = Base area × Height
Given height = 9m
Since the prism is a triangular based prism,
Base area = area of the equilateral triangle = 1/2bh
base of the triangle = 4m
Height can be gotten using Pythagoras theorem.
Slant side of the triangle is the hypotenuse = 4m
Adjacent = 1/2 of the base = 1/2(4)= 2m
Height = √4²-2²
Height = √16-4
Height of the triangle= √12 m
Base Area = 1/2×4×√12
Base Area = 2√12 m
Volume of the prism = 2√12 × 9
= 2×2√3×9
= 36√3 m³
= 62.2m³
Volume of the prism is approximately 62m³
