The slope is -2. -5 - 3 = -8÷4 = -2.
Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle=
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
Answer:
The material will be used for 24 days.
Step-by-step explanation:
Given that:
Materials made in a month = 240 tonnes
More materials to be made = 60 tonnes
Total material to be made = 240+60 = 300 tonnes
Days in a month = 30 days
Materials : Days
240 : 30
300 : x
As the production is increasing, the material will be used before 30 days.
This is an inverse proportion.
Using cross multiplication;
300*x = 240*30
300x = 7200
Dividing both sides by 300
Hence,
The material will be used for 24 days.
