Options :

A) 12⟌60

B) 60 ÷ 12

C) 60⟌12

Answer:

C) 60⟌12

Step-by-step explanation:

Given that :

Total cost of inviting 12 guests to a party = $60

To obtain the cost per guest :

Total cost of invitation / number of guests

That is ; we divide the cost of inviting the guests by the number of guests invited

$60 / 12 = 12⟌60

The expression 60⟌12 is incorrect as this means 12 / $60

CAN SOMEONE HELP ME WITH THIS!!
DIA [1.3K]

Answer:

Number of dogs = 6

Number of burgers = 11

Step-by-step explanation:

Number of dogs = x

Number of burgers = 2x - 1

Cost of a dog = $ 1.50

Cost of 'x' dogs = 1.5x

Cost of a burger = $ 2

Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2

                                    = 4x - 2

Total amount collected  = $ 31

1.5x + 4x - 2 = 31 {add 2 to both sides}

        1.5x + 4x = 31 + 2

      1.5x+ 4x  = 33

               5.5x = 33

                    x = 33/5.5

                   x = 6

Number of dogs  = 6

Number of burgers = 2*6 - 1 = 12 - 1 = 11

Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of
adelina 88 [10]

Answer:

L = 10(\frac{1}{2} )^{t-4}

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be S = 10(\frac{1}{2} )^{t}.

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be L = 10(\frac{1}{2} )^{t-4}. (Answer)
