A gardener weeds 2/3 of a flower bed in 6 min. How much of the flower bed did the gardener weed in 1 min?

(50 pts) (This is my own experiment 2 see how fast Brainly is and how efficient!)

Answers

Answer 1
Answer: (2/3 bed) / (6min) = ('x' bed) / (1min)

Cross-multiply:

             (2/3 bed * 3min) = ('x' bed * 6min)

Divide each side by 6min:

                 1/3 bed = 'x' bed

A quadratic equation always has exactly two solutions.  If the quadratic
expression is a perfect square, then they're both the same solution.
Quadratic equation can have maximally two solutions if delta>0.

Eqyivalent expresion to 3√m^2n^5

Answers

The first step to solving this expression is to factor out the perfect cube
\sqrt[3]{m^(2) n^(3) X n^(2) }
The root of a product is equal to the product of the roots of each factor. This will make the expression look like the following:
\sqrt[3]{ n^(3) } \sqrt[3]{ m^(2) n^(2) }
Finally,, reduce the index of the radical and exponent with 3
n\sqrt[3]{ m^(2) n^(2) }
This means that the correct answer to your question is n\sqrt[3]{ m^(2) n^(2) } .

Suppose you are determining the growth rate of two species of plants. Species A is 12 cm tall and grows 2 cm per month. Species B is 10 cm tall and grows 3 cm per month. Which system of equations models the height of each species H(m) as a function of months m.H(m ) = 2 + 12m
H(m ) = 3 + 10m

H(m ) = 2 + 12m
H(m ) = 10 + 3m

H(m ) = 12 + 2m
H(m ) = 3 + 10m

H(m ) = 12 + 2m
H(m ) = 10 + 3m

Answers

Answer:

The equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m

Step-by-step explanation:

As given

The growth rate of two species of plants.

Species A is 12 cm tall and grows 2 cm per month.

The height of each species is represented by H(m) as a function of months m.

Than the equation becomes

H(m) = 12 + 2m

As given

Species B is 10 cm tall and grows 3 cm per month.

Than the equation becomes

H(m) = 10 + 3m

Than the equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m
H(m) = 12 + 2m
H(m) = 10 + 3m

Answer: b > 13

Step-by-step explanation: b= 14 and 14 is larger than 13. So using the greater than symbol is correct.

Answer:

b > 13

Step-by-step explanation:

Because, if you recall seeing that b = 14 above the question, then you would say that b is greater than 13 because b = 14.
