the area of a rectangular picture frame is 30 3/1 square inches. The length of the frame is 6 1/2 inches. Find the width of the

Rudiy27

I hope this helps you

Area=length ×width

30 1/3=30.3+1/3=91/3

6 1/2=6.2+1/2=13/2

91/3=13/2.width

width =7.13.2/3.13

width =14/3

width = 4 2/3

Please help ASAP !! :)

Answer:

temperature is decreasing as time passes
x-axis
hot drink temperature (°C)

Step-by-step explanation:

1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.

2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.

3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.
