Answer:
length of BC = 5 1/4 feet
Step-by-step explanation:
Area of a triangle = 1/2×base×height
Area = 4 3/8 square feet
Base = AC= 1 2/3 feet
Height = BC = ?
Area of a triangle = 1/2×base×height
4 3/8 = 1/2 × 1 2/3 × height
35/8 = 1/2 × 5/3 × height
35/8 = 5/6 × height
Height = 35/8 ÷ 5/6
= 35/8 × 6/5
= (35 × 6) / (8 × 5)
= 210 / 40
= 5 1/4 feet
Height = BC = 5 1/4 feet
length of BC = 5 1/4 feet

Answer:
Step-by-step explanation:
It should be diagonal not diameter.
The diagonal of the square is √2 time the side.
The side given 1 unit, then the diagonal is x = √2 units
Answer:
The equivalent to one over five m − 20 is one over five (m − 100) ⇒ B
Step-by-step explanation:
Let us solve the question
∵ One over five means 
∴ One over five m - 20 = m - 20
→ By using the distributive property, take one over five as a common factor
from both terms
∴ m - 20 = 
- 
→ Simplify the bracket
∵ m ÷ = m × 5 = m
∵ 20 ÷ = 20 × 5 = 100
∴ - = (m - 100)
∴ m - 20 = (m - 100)
The equivalent to one over five m − 20 is one over five (m − 100)
12 inches, 180/30 is 6 and 2x6 is 12
