12 gallons

Step-by-step explanation:

If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.

The equation is correct :)

Step-by-step explanation:

Answer:

63 cm^2

Step-by-step explanation:

p = l + w + l + w

32 = 2l + 2w

32 = 2(w + 2) + 2w

32 = 2w + 4 + 2w

32 = 4w + 4

28 = 4w

7 = w

l = w + 2

l = 7 + 2

l = 9

Check your work:

32 = 9 + 7 + 9 + 7

32 = 32

Correct

A = l × w

A = 9 × 7

A = 63

Step-by-step explanation:

Answer:

log 2 8 is 3.

Step-by-step explanation:

Log2 8=Log(8) ÷ Log(2)

Log(8)= 0.903089986992

Log(2)=0.301029995664

Log2 8=0.903089986992 ÷ 0.301029995664

Given:

Perimeter of a regular pentagon = 10 cm

The pentagon is dilated by a scale factor = [tex]\dfrac{3}{2}[/tex].

To find:

The perimeter of the new pentagon.

Solution:

If a figure is dilated by a scale factor k, then

Perimeter of new figure = k × perimeter of original figure

The scale factor is [tex]\dfrac{3}{2}[/tex] and the perimeter of a regular pentagon is 10 cm. So, the perimeter of a new pentagon is:

[tex]\text{Perimeter of new pentagon}=\dfrac{3}{2}\times 10[/tex]

[tex]\text{Perimeter of new pentagon}=3\times 5[/tex]

[tex]\text{Perimeter of new pentagon}=15[/tex]

Therefore, the perimeter of the new pentagon is 15 cm.

Step-by-step explanation:

Answer:

81 hours

Step-by-step explanation:

Let x be the time are needed

45：5 = x：9

5x = 45×9

5x = 405

x = 81

The time it takes 9 men working at the same pace to build this wall​ is 81 hours

Let x be the time are needed for 9men

If it takes five-man take 45 hours to build a wall then, we can have the ratio

45：5 = x：9

5x = 45×9

5x = 405

x = 81

Hence the time it takes 9 men working at the same pace to build this wall​ is 81 hours
