Answer:
We have 7n < 6 - 48;
7n < - 42;
n < -6;
Then, 3n - 4 ≤ 8;
3n ≤ 12;
n ≤ 4;
Step-by-step explanation:
Proportions are when you yet the ratio of something. Meaning part of something and how it would become whole
The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²
<h3>Surface area</h3>
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
where,
- a = sides of base = 10 cm
- h = slant height = 15 cm
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
= 10² + 2(10)√10²/4 + 15²
= 100 + 20√100/4 + 225
= 100 + 20√25 + 225
= 100 + 20√250
= 100 + 20(15.81)
= 100 + 316.2
= 416.2 cm²
