i five man take 45 hours to build a wall how long will it take 9 men working at the same pace to build this wall
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
Ratio and proportionsLet 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

Answer:
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.

Answer:
W = 87 degrees
Step-by-step explanation:
First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:
tanW/tan = 19.0811/tan
W = 19.0811/tan
Now we can use the inverse tan function on the calculator ([tex]tan^{-1}[/tex]) to calculate it:
W = 19.0811 x [tex]tan^{-1}[/tex]
W = 87 degrees

A regular pentagon with a perimeter of 10 cm is dilated by a scale factor of 3/2 to create a new pentagon. What is the the perimeter of the new pentagon?
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.

the perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area
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
