Answer:
<u>25 hours</u>
Step-by-step explanation:
It takes 5 men 45 hours to build a wall.
So, if no. of men increases by 1.8 [∴ 5 x 1.8 = 9],
then time taken reduces by that same amount.
=> 45 hours / 1.8
=> 45 / (9/5)
=> 45 x 5 / 9
=> 5 x 5
=> <u>25 hours</u>
Answer:
In general, the salary S in terms of years of experience Y is S = 2700Y + 3200
Step-by-step explanation:
we start at 32000 without experience.
as the experience goes up, the wage increases 2700 per year so we can multiply 2700 by the years of experience to find the increase of salary. To find the salary of a certain employee with a certain amount of experience, plug the years of experience in for Y and solve.
for Y=0
S= 2700(0) + 3200 = 0 + 3200 = 0
for Y=2
S= 2700(2) + 3200 = 5400 + 3200 = 8600
for Y=5
S= 2700(5) + 3200 = 13500 + 3200 = 16700
for Y=7
S=2700(7) + 3200 = 2700(5) + 2700(2) + 3200 = 5400 + 13500 + 3200 = 22100
Find area of the semi circle.
The diameter is, half of that would be the radius, which is 3.
= 14.1
Find the area of the rectangle.
6 * 4 =24
Add the two areas together.
24 + 14.1 = 38.1
