A water sprinkler has a range of 5meters. The jet of water from the sprinkler sweeps out at an angle of 85degrees as the nozzle turns. What is the area watered by the sprinkler?

Answers

Answer 1

Answer: It's (85/360) of a full circle with a radius of 5meters.

Answer 2

Answer:

Answer:

I found the image that accompanied this problem.

We need to solve for the area of the sector.

A = n/360 * π * r²

A = 85/360 * 3.14 * 5²

A = 0.2361 * 3.14 * 25

A = 18.5347

Answer is C. 18.5 square meters.

Jeremy drove from Portland to Miami. He determines that the expression 450x + 150 represents the distance in miles he traveled, where x is the number of days after the first day. Which statement describes correctly what the coefficient of x represents?

Answers

Answer:

The coefficient of x represents the number of miles driven each day.

Step-by-step explanation:

The coefficient of x is being multiplied by x, or the number of days. If the expression models the total distance travelled, then Jeremy drove 450 miles each day.

Which box is greater a 1.5 pound box of raisins or a 650 gram box of raisins?

An angle of size 124 degrees has been rotated d degrees around a center 0 what is the size of the rotated angle?

Answers

Answer:

124

Step-by-step explanation: Hope it helps

Final answer:

No matter how much the angle is rotated around the center, the size of the angle remains the same. Therefore, even after the rotation, the size of the angle is still 124 degrees.

Explanation:

When an angle is rotated around a center, the size of the angle doesn't change.

It's an important characteristic of angle rotation. So, if an angle of 124 degrees is rotated d degrees around a center, the size of the rotated angle will still remain 124 degrees. It is just in its new position after rotation. Regardless of the rotation of the angle, its size or measure remains the same as the rotation does not affect the measure of the angle.
