Answer:
Step-by-step explanation:
∵ The volume of the pyramid = 1/3 base area × height
∵ The base is equilateral Δ with side length 4
∴ The area of the bast = 1/4 × 4² × √3 = 4√3 units²
To get the height of the pyramid draw it from the vertex of the top of the pyramid ⊥ to the base on the centro-id of the base which divides the height of the triangle two ratio 2:1 from the vertex of the triangle
∵ The height of the base = √(4² - 2²) =√12 = 2√3
∴ 2/3 the height = 4√3/3 ⇒ (2:1 means 2/3 from the height)
∴ The height of the pyramid = √[4² - (4√3/3)²] = √[16 - 48/9]
∴ h = 4√2/√3 (4√6/3 in its simplest form)
∴ V = 1/3 × 4√3 × 4√2/√3 = 16√2/3 units³
∴

Answer:
we can make 5 servings of spice rub from 10 table spoons of onion powder
Step-by-step explanation:
Given the data in the question;
2 table spoon of onion powder makes one serving of spice rub.
Total table spoons of onion powder available = 10
So Let x represent the number of servings of spice rub we can make from our 10 table spoons of onion powder ;
2 table spoons = 1 servings
10 table spoons = x servings
we cross multiply;
x servings × 2 table spoons = 10 table spoons × 1 servings
x servings = ( 10 table spoons × 1 servings ) / 2 table spoons
x = 10 / 2
x = 5 servings
Therefore, we can make 5 servings of spice rub from 10 table spoons of onion powder
