one bouquet of flowers has 3 roses for every 5 carnations. other bouquet has 4 carnations for every 5 daisies. if both bouquets
Leno4ka [110]

Answer:

therefore the second bouquet will have more flowers , as it will have 25 daisies

Step-by-step explanation:

3 roses for every 5 carnations

5 daisies for every 4 carnations

we can solve this using cross multiplication

3 : 5

x : 20

5x = 60

x = 60/5

<em>x = 12</em>

meaning that for a bouquet that has 20 carnations there will be 12 roses

5 : 4

x : 20

4x = 100

<em>x = 25</em>

meaning that for a bouquet that has 20 carnations there will be 25 daisies.

<u>therefore the second bouquet will have more flowers , as it will have 25 daisies</u>

Alex is building a rectangular fence around his yard. The total perimeter of the fence is 68 feet and the area of the yard is 24
pychu [463]

Perimeter (P) = 2L + 2w


68 = 2L + 2w


68 - 2L = 2w


2(34 - L) = 2(w)


34 - L = w


********************                                


Area (A) = L * w


     240 = L (34 - L)


     240 = 34L - L²


L² - 34L + 240 = 0


(L - 10)(L - 24) = 0


L = 10  or  L = 24


w = 34 - L   = 34 - 10   = 24      or      w = 34 - 24   = 10


Answer: width = 10, length = 24   assuming length is bigger than the width
