Answer:

18 ft/ 20 min = 0.90 ft/min is the greatest speed.

Step-by-step explanation:

You must find the unit rate of change for all four items:  A through D.  This will require some conversion of units of measurement.  Next you must determine which of your four results is the greatest / fastest.

A.  18 ft / 20 min = 9/10 ft/min, or 0.90 ft/min

B.  90 ft / 2.5 hr = 90 ft / 150 min = 6/10 ft/min, or 0.6 ft/min

C.  20 yd / 1.5 hr = 60 ft / 90 min = 6.7/10 ft/ min, or 0.67 ft/min

D.  3 2/3 yd / 15 min = (11/3)(3 ft) /  15 min = 7.3/10 ft /min, or 0.73 ft/min

Arranged in increasing size, we have:

6/10 ft/min, 6.7/10 ft/min, 7.3/10 ft/min and 9/10 ft/min.

The first answer choice, 9/10 ft/min, is the greatest speed.

You would have to make 465=1550-7 1/2 x and find x
Subtract 1550 from both sides
-1085=-7 1/2x
Divide -7 1/2 on both sides
And the answer is 144 2/3

a box cost $2.48, but it is on sale for $1.49. How much do you save on one box when bought on sale? Now how much would you save
Thepotemich [5.8K]

Answer:

1. $0.99

2. $1.98

Step-by-step explanation:

1. From the question we have

Cost of box = $2.48

Selling price = $1.49

That is the box is discounted from $2.48 to $1.49

Therefore, amount saved = $2.48 - $1.49 = $0.99

2. The amount saved from buying a second box is hence;

2 × $0.99 = $1.98

Hence, as the number of boxes bought increases, the amount saved increases
