Answer:
Here is your answer C
Step-by-step explanation:
Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own

Answer:
Step-by-step explanation:
Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. The formula for determining the area of a circle is expressed as
Area = πr²
Where
π is a constant whose value is 3.14.
r represents the radius if the circle.
The area covered by one of Mr. Rives' rotating sprinkler would be
3.14 × 7² = 3.14 × 49 = 153.86ft²
Therefore, the maximum area of lawn that two sprinklers can cover would be
153.86 × 2 = 307.72 ft²
