Answer:

d = 0.666t , where d is in miles and t is in minutes.

d = 39.94h, where d is in miles and h is in hours.

Step-by-step explanation:

A car travels 2\frac{1}{3} = 2.33 miles in 3\frac{1}{2} = 3.5 minutes at a constant speed.

Let the relation between the distance (d) traveled by car in miles after traveling t minutes is d = kt ......... (1)

Now, putting d = 2.33 miles and t = 3.5 minutes in the above equation we get,

2.33 = 3.5k

⇒ k = 0.666 (Approx.)

So, the equation (1) becomes d = 0.666t. (Answer)

Let us assume that the relation between the distance (D) traveled by car in miles after traveling h hours is d = Kh ............ (2)

Now, putting D = 2.33 miles and T = 3.5/60 = 0.058 hours in the above equation, we get

2.33 = 0.058K

⇒ K = 39.94

So, the equation (2) we get, d = 39.94h (Answer)

Bogdan [553]
answer: 360

Given:
Machine A Candy Packing
x(minutes)  y(candies)
  5               600
10             1200
15             1800
20             2400

Machine B : y = 150x

Find number of candies packed in 12 minutes.

Machine A : 600/5mins = 120 candies per minute
120 * 12 minutes = 1,440 candies

Machine B : y = 150x ⇒ y = 150(12) ⇒ y = 1,800

Machine B: 1,800
Machine A: 1,440
Difference      360

Machine B packed 360 more candies than Machine A in 12 minutes.

Help me with this algebra please:)

-5(x+7)<-10
ok so we need to distribute the -5 into the x and 7.
-5x+-35<-10
then, we combine like terms. 
-5x+-35<-10
       +35  +35
 -5x<25
Then, we get the variable to be by itself.
-5x<25
divide by -5
x<-5 

Hope this helps! If you still don't get it, ask me.

A new homeowner buys 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each si
Marina CMI [18]
As it is emphasized above, the area (A) of a square is the square of its sides (l),
                               A = l²
The area of the square should be 120 ft². Substituting this to the equation,
                             120 ft² = l²
Solving will give us an answer of l being approximately equal to 10.95 ft.
