A vendor sells h hot dogs and s sodas. If a hot dog costs twice as much as a soda, and if the vendor takes in a total of d dolla
horrorfan [7]

Answer:

The expression for the cost of soda is 100 ×  \dfrac{\textrm d}{ \textrm 2h + \textrm s} cents

Step-by-step explanation:

Given as :

The quantity of hot dogs sold by vendor = h

The quantity of sodas sold by vendor = s

The total cost of hot dogs and soda = $ d

Let The price of hot dogs = $ x

And The price of soda = $ y

Now, According to question

The price of hot dogs is twice as much as soda

so, $ x = 2 × $ y

I.e   x = 2 y

and $ x h + $ y s = $ d

Or , 2 × $ y  h + $ y s = $ d

Or, y = \dfrac{\textrm d}{ \textrm 2h + \textrm s}

∵ 1 dollar = 100 cents

So, the price of  \dfrac{\textrm d}{ \textrm 2h + \textrm s} = 100 ×  \dfrac{\textrm d}{ \textrm 2h + \textrm s} cents

Hence The expression for the cost of soda is 100 ×  \dfrac{\textrm d}{ \textrm 2h + \textrm s} cents  Answer

What is the area of the figure? A rectangle is cut out of a large rectangle. The larger rectangle has a base of 6 yards and heig
Vikentia [17]

Answer:

Small one: 18 and 1-thirds yards²  Large one: 43.5 yards²

Step-by-step explanation:

Area of rectangle= base*height

Large one: base = 6, height= 7.25 (7 and 1-fourth)

Area= 43.5yards²

Small one: base = 3(2/3 or 2-thirds), height= 5

change the mixed fraction 3(2/3) to 11/3

area= 11/3 * 5 = 55/3

change to mixed fraction which = 18(1/3)
