1. The length of a rectangle is 3 in. more than the width. The perimeter of the rectangle is 24 in.
Westkost [7]

Answer:

Let the width be x

Length = x + 3

Perimeter = 2(l+b)

24 = 2(x+3+x)

12 = 2x + 3

2x = 9

x = 4.5

Width = 4.5 in

Length = 4.5+3 = 7.5 in.

Hope this helps!

The combined volume of all the things and aquarium is 1.25×10 to the six power gallons the aquarium plants to install a new dolp
ella [17]

Answer:

1,500,000 gallons

Step-by-step explanation:

In this question, we are to calculate the total volume of the aquarium after installing a new dolphin tank.

Mathematically, to calculate this, we simply need to add the the volume of the new dolphin tank to the volume of the things in the aquarium before bringing the dolphin tank.

The volume of all the things in the aquarium before installing the dolphin tank is 1.25 * 10^6 = 1,250,000 gallons

now let’s add the volume of the dolphin tank which is 250,000 gallons

that would be 1,250,000 + 250,000 = 1,500,000 gallons or 1.5 * 10^6 gallons

The length of a rectangular piece of steel is 4 meters less than double the width. The perimeter of the steel is 22 meters find
lesantik [10]

Answer:

Length= 6 m         \\ Width = 5m

Step-by-step explanation:

Let the width of the piece be 'W'

Length of the piece be 'L'

According to the given statement

                Length=2W-4

Perimeter = 22 m

Perimeter of the rectangular sheet=

                                 2(L+W)\\                   22= 2(2W-4+W)\\             22=2(3W-4)\\               11=3W-4\\                 3W=11+4\\                 3W=15\\                     W= 5\\

   Length=2W-4

                =2(5)-4\\=10-4\\Length=6 m

   Length= 6 m         \\ Width = 5m
