Answer:
k/9 < 1/3
k < 3
Step-by-step explanation:
quotient is division
k/9 < 1/3
Multiply each side by 9
k < 9/3
k < 3
Answer:
l x - 9 l ≤ 0.3y
Step-by-step explanation:
Let x is the length of the pipe
Let y is the length of the diameter
Given that:
- A pipe is to be cut to a length of 9 accurate, we have : x - 9
- Within three tenths of its diameter : 0.3 y
So we have the inequality that model this situation is:
l x - 9 l ≤ 0.3y
Hope it will find you well.
Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
