Answer:

r =√[3V/(π h)]

Step-by-step explanation:

V = ⅓ × π r²h

=> multiplied by 3

3V = π r² h

=> find r²

r² = 3V/(π h)

=> find r

r =√[3V/(π h)]

Suppose you are determining the growth rate of two species of plants. Species A ls 25 cm tall and grows 3 cm per month. Species
exis [7]

Answer: Last Option

H (m) = 25 + 3m\\H (m) = 10 + 8m

Step-by-step explanation:

The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.

If m represents the number of months elapsed then the equation for the height of the plant of species A is:

H (m) = 25 + 3m

For species B the initial height is 10 cm and it grows 8 cm each month

If m represents the number of months elapsed then the equation for the height of the plant of species B is:

H (m) = 10 + 8m

Finally, the system of equations is:

H (m) = 25 + 3m\\H (m) = 10 + 8m

The answer is the last option

postnew [5]

Answer: 3/5 = (6/10). There are 10 TOTAL marbles in the bag.

Step-by-step explanation:

Since it is a question of fractions, you can assume any reasonable number and work with the numbers. We know initially that there are 6 marbles and they are ALL blue and the rest are another color or colors. So BLUE = 6/10 and the other colors 4/10 for 2/5.
