- the formula of n-th term of an arithmetic sequence.
We have:
Answer: C. 77.4
Answer:
No
Step-by-step explanation:
2x+5.2 + 3x+ 1.2 +2x+6.2= 180
7x+ 12.6=180
7x 12.6 - 12.6=180 -12.6
7x = 167.4
x = 23.914
should equal 60
Answer: The volume of the solid is 324 cm³
Step-by-step explanation:
Formula for determining the volume if a cube is s³
Where s represents the length of each side of the cube.
From the information given, s = 6 cm
Volume = 6³ = 216 cm³
The formula for determining the volume of the square base pyramid is expressed as
Volume = Area × height × 1/3
From the information given,
Length of square base = 6 cm
Height = 6 cm
Area of square base = 6² = 36 cm²
Volume of square base pyramid
= 36 × 6 × 1/3 = 108 cm³
The volume of the solid would be the sum of the volume of the cube and the volume of the square base pyramid. It becomes
216 + 108 = 324 cm³
