Answer:
The volume of the regular tetrahedron is 283.5 m³
Step-by-step explanation:
The formula of the volume of the regular tetrahedron is V = 
A h, where
∵ The area of the base of a regular tetrahedron is 98.9 m²
∴ A = 98.9 m²
∵ The height of it is 8.6 m
∴ h = 8.6 m
→ Substitute them in the formula of the volume above
∵ V = (98.9)(8.6)
∴ V = 283.5133333 m³
→ Round it to the nearest tenth of a cubic meters
∴ V = 283.5 m³
∴ The volume of the regular tetrahedron is 283.5 m³
Answer:
The value of y = 4.3
Step-by-step explanation:
It is given that,
5/7 = y/6
<u>To find the value of y</u>
We have, 5/7 = y/6
(5 * 6) = (y * 7)
y * 7 = 5 * 6
y = (5 * 6)/7
= 30/7
= 4.29
≈ 4.3
Therefore the correct answer, the value of y = 4.3
Find current interest:
=$2543.32 * 17.4%
=2543.32 * 0.174
=442.537
Add the interest to the current balance:
=2543.32 + 442.537
=2985.857
Add new transaction:
=2985.857 + 320
=3305.857 rounded to 3305.86
The answer is C) $3305.86
