When multiplying numbers with exponents, you have to add the exponents. So 4r^3×2r^2 equals 8r^5.

Answer: 8</h2>
Step-by-step explanation:

Therefore, Mel has to work at least 7.5 hours or 8 total hours.
If the measure of an angle "θ" is 7(π/6), then it's equivalent measurement in degrees is 210°.
As per question statement, we have an angle "θ" whose measurement in radians is 7(π/6). We have to convert this radians into its equivalent measurement in degrees. Thus, to solve this question, we will have need to know the relation between radians and degrees, which goes as,
("π" Radian = 180°).
Then, we will apply unitary method to our provided data and use the above-mentioned relation to obtain our desired answer, i.e.,
π Radian = 180°,
then, 7π Radian =
°,
Then, 7(π/6) Radian =
°.
- Radian: This is an unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
- Degrees: This is another unit of measurement of angles, one unit of this being equal to one three-hundred-and-sixtieth of the circumference of a circle.

Answer:
45
Step-by-step explanation:
Answer: 3.6m
9m times 40m which equals 360m, then divide it by the 100 meters length and it will become = 3.6m
