lana66690 [7]

Answer:

Width= 13 cm

length=30cm

Step-by-step explanation:

Let the length of the rectangle be 'L'

And the width of the rectangle be 'W'

Perimeter= 86 cm

According to the statement:

        Length= 2*Width+4\\L=2W+4

Perimeter of a rectangle= 2(Length+Width)

86=2(2W+4+W)\\86/2=3W+4\\43=3W+4\\3W=43-4\\3W=39\\W=39/3\\W=13 cm\\\\Length(L)=2W+4\\=2(13)+4=26+4=30 cm\\Length=30 cm

                               Width= 13 cm

                                length=30cm

At 2pm the level of the water in the pool was 10 feet. At 6pm the level of water was 2 feet. Find the constant rate of the water
adelina 88 [10]
Assuming that the pool was drained at a constant rate, the speed at which it was drained can be expressed as a function of time. In this case, the pool level will be expressed in feet per hour.

The time changed by 4 hours (6-2), and the level of the pool changed by -8 feet (2-10). Diving the feet by the hours to get the rate of decreasing depth, we find that the rate equals -2 feet/hour.

Tracy bought 8 gallons of orange juice and used 1.8 gallons of it to make popsicles. How much orange juice does Tracy have left?
malfutka [58]

Answer:

6.2 gallons of orange juice left.

Step-by-step explanation:

Total orange juice = 8 gallons

Used orange juices to make popsicles = 1.8 gallons

We need to find how much orange juice does Tracy have left.

Left orange juice = Total orange juice - used orange juice

= 8 gallons - 1.8 gallons

= 6.2 gallons

Hence, 6.2 gallons of orange juice left.
