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

A soccer player is going to kick a soccer ball from one corner of a field to the opposite corner. If the field is 80 meters long and 60 meters wide, how far will the soccer player have to kick the ball
Answer:
100 meters
Step-by-step explanation:
To figure this out, do the Pythagorean theorem
a^2 + b^2 = c^2
60^2 + 80^2 = c^2
3600 + 6400 = c^2
10000 = c^2
c = 100
Answer:
100 meters
Step-by-step explanation:
a^2 + b^2 = c^2

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
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.
