Answer:
21 ft by 28 ft
Step-by-step explanation:
To maximize the area, see the attached.
Perimeter will be 4l+3w which is equal to the fencing perimeter, given as 168
4l+3w=168
Making l the subject then
4l=168-3w
l=42-¾w
Area of individual land will be lw and substituting l with l=42-¾w
Then
A=lw=(42-¾w)w=42w-¾w²
A=42w-¾w²
Getting the first derivative of the above with respect to w rhen
42-w6/4=0
w6/4=42
w=42*4/6=28
Since
l=42-¾w=42-¾(28)=21
Therefore, maximum dimensions are 21 for l and 28 for w
In order to solve this, you need to put it into a fraction form.
First for every 225 employees there's 27 supervisors.
25 x
___ = ___
225 252
I got the 252 by adding 225+27(who are the new employees)
So then you need to cross multiply. And get them to equal the same number.
So 25×252= 6,300
Then Divide 6,300 by the old denominator 225.
6,300÷225= 28 new employees
Therefore there will be a total of 28 employees.
Hope this helped!
Answer:
15 feet
Step-by-step explanation:
1 yard = 3 feet
2 yards = 6 feet
3 yards = 9 feet
4 yards = 12 feet
5 yards = 15 feet
4 times 4 which is 8 so 8 times 4 which is 32 so divide that by 138 but divide the 138 first and you will get 17.25?
Answer:
X = 11
Complementary angles
Step-by-step explanation:
Complementary angles are when two angles add up to 90 degrees.
3x + 10 + 47 = 90
3x + 10 = 43
3x = 33
x = 11
