Which algebraic equation best represents Jarrett's hair growth rate? David's hair grows at a rate four times as fast as Jarrett'
2 answers:
Answer:
D.
Step-by-step explanation:
Let D represent David's hair growth and J represent Jarrett's hair growth.
We have been given that David's hair grows at a rate four times as fast as Jarrett's. We are asked to find the algebraic equation that best represents Jarrett's hair growth rate.
We can represent our given information in an equation as:
Dividing both sides by 4 we will get,
Therefore, the equation best represents Jarrett's hair growth rate and option D is the correct choice.

Answer:
The first one. 4 times square root of 3.
Step-by-step explanation:
The side of the equilateral triangle that represents the height of the triangle will have a length of because it will be opposite the 60o angle. To calculate the area of the triangle, multiply the base (one side of the equilateral triangle) and the height (the perpendicular bisector) and divide by two.
<u>The given options are:</u>
(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
(B)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the circumference of the circle will yield the area of the sector.
(C)the central angle measure of the sector multiplied by the area of the circle will yield the area of the sector.
(D)the central angle measure of the sector multiplied by the circumference of the circle will yield the area of the sector.
Answer:
(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
Step-by-step explanation:
The area of the shaded sector can be determined using the formula:
Therefore, the formula is:
Therefore, the formula is best explained by Option A.
