If a windshield wiper covers an area of approximately 160 square inches when it rotates at an angle of 84°, find the length of the wiper to the nearest tenth of an inch.

General Idea:

We can use the below formula to find the area of sector (A), when angle of sector and radius is given:

Applying the concept:

We need to substitute 84 for and 160 for A in the above formula:

Conclusion:

If a windshield wiper covers an area of approximately 160 square inches when it rotates at an angle of 84°, the length of the wiper to the nearest tenth of an inch is 14.8

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

really your just stupid if you don't know this
