Zina [86]

Answer: 121.52 square feets

Step-by-step explanation:

The room has the shape of a rectangle and its dimensions are 12.4 feet long and 9.8 feet wide. This means that dimension of the carpet is also 12.4 feet long and 9.8 feet wide. To replace the rectangular carpet with tiles, the area of the tiles must be equal to the area of the carpet. The area of the carpet is determined by length × width.

Length of the room or carpet = 12.4 feets

Width of the room or carpet = 9.8 feets

The number of square feets of tiles that Wes will need

=12.4 ×9.8 = 121.52 square feets

Is there more wood in a 60​-foot-high tree trunk with a radius of 2.2 feet or in a 50​-foot-high tree trunk with a radius of 2.6
Sladkaya [172]

Answer:

V₂=1061.85 ft³

Step-by-step explanation:

To determine where more wood is found, just find the volume of each log and see which one has the largest volume

knowing that the volume of a straight cylinder is

V=πR²h, where R=radius and h=height

V_{1}=\pi  (2.2)^{2}60= 912.31ft^{3}\\V_{2}=\pi  (2.6)^{2}50= 1061.85ft^{3}

As we can observe

V₂>V₁

The volume of the cuboid is 120 cm<br> Find x<br> 5 cm<br> 4 cm
belka [17]

Answer:

6cm

Step-by-step explanation:

Volume of cuboid = length × breadth × height

Length = x

Breadth = 4cm

Height = 5cm

Volume = 120cm³

Volume = 4 × 5 × x

120 = 20x

Divide both sides by 20

20x/20 = 120/20

x = 6cm

Is 1/4 the answer to this what ratio forms a porportion with 8/36
Flauer [41]
I don't think so. 1/4 and 8/36. 1 times 8 is 8 but 4 times eight is 32 so it would be 8/32.
