Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses. She evenly distributed the plant food among 4 rose bushes. How many cups of plant food were used for each rose bush?

Answers

Answer:

3 7/8 cups plants food

Step-by-step explanation:

peat moss = 3 ½ cups

compost = 5 ¼ cups

fertilizer = 6 ¾ cups

Total mixture = peat moss + compost + fertilizer

= 3 ½ cups + 5 ¼ cups + 6 ¾ cups

= 7/2 + 21/4 + 27/4

= 14+21+27/4

= 62/4

Total mixture = 62/4 cups

She evenly distributed the plant food among 4 rose bushes

Each rose bush uses = Total mixture / number of rose bushes

= 62/4 ÷ 4

= 62/4 × 1/4

= 62/16

= 3 14/16

= 3 7/8 cups plants food

Each rose bush uses = 3 7/8 cups of plants food

hey guys please answer if you know​

Answers

Answer:

19

Step-by-step explanation:

note that

(a + b)² = a² + b² + 2ab , that is

a² + b² + 2ab = (a + b)² ← subtract 2ab from both sides

a² + b² = (a + b)² - 2ab

           = 5² - 2(3)

           = 25 - 6

          = 19

Answer:

19

Step-by-step explanation:

since value of both a+b and a*b are given

formula for a^2 + b^2 is (a+b)^2-2*a*b

Substituting those value,

a^2+b^2=5^2-2*3

i.e. 25-6

=19

A company offers two monthly plans. Plan A costs $ 25 plus an additional $0.10 for each minute of calls. Plan B costs $18 plus an additional $0.15 for each minute of calls.

Answers

Answer:

The indifference point is 140 minutes.

Step-by-step explanation:

Giving the following information:

Plan A costs $ 25 plus an additional $0.10 for each minute of calls.

Plan B costs $18 plus an additional $0.15 for each minute of calls.

First, we need to establish the total cost formula for each plan:

Plan A= 25 + 0.1*x

Plan B= 18 + 0.15*x

x= number of minutes

Now, to calculate the indifference point, we equal both formulas and isolate x:

25 + 0.1x = 18 + 0.15x

7 = 0.05x

140=x

The indifference point is 140 minutes.

Prove:

Plan A= 25 + 0.1*140= $39

Plan B= 18 + 0.15*140= $39
