hancock building dimensions. the top of the john handcock building in Chicago is a rectangle whose length is 60ft more than width. the perimeter is 520 ft. find the width and the length of the rectangle. find the area of the rectangle.
Answers
Length = x + 60 ft
Width = x
Perimeter = 520
Perimeter = 2(L+W)
520 = 2(x+60) + 2(x)
520 = 2x + 120 + 2x
520 = 4x + 120
520 - 120 = 4x
400 = 4x
400/4 = x
100 = x
Length = x + 60 = 100 + 60 = 160 ft
Width = x = 100 ft
Area = Length * Width
A = 160ft * 100ft
A = 16,000 ft²

y(y + 5) = 750
y2 – 5y = 750
750 – y(y – 5) = 0
y(y – 5) + 750 = 0
(y + 25)(y – 30) = 0
Answers
Answer:
Option B , C and E are correct
(y+25)(y-30)=0
Step-by-step explanation:
Given : Area of rectangular room is 750 square feet.
Width of the room is 5 feet less than the length of the room.
Let y be the length of the room
then,
As per the given condition
width of the room is: y-5
Area of rectangle is multiply the length by its width.
Area of rectangle =
Substitute the given values in above formula we get;
......[1]
or we can write this as;
750 -y(y-5)=0
[1] ⇒ or
or
(y+25)(y-30)=0
Therefore, the equation which can be used to solve for y are;
,
and (y+25)(y-30)=0
A:False
B:True
C:True
D:False
E:True
y = x + 7
y = x - 7
y = x + 5

Answer:
it would cost $34.50 to purchase 7.5 lbs of walnuts.
Answer:
$34.50
Step-by-step explanation:
First find out how much 1/4 of a lb will cost.
3.45/3= 1.15
This is the cost for only 1/4 a lbs of chopped walnuts. Take this number and multiply it by 4 to find how much it would cost for 1 whole pound of walnuts.
1.15x4= 4.60
It costs $4.60 for a whole pound of walnuts. If you are trying to find how much it costs for 7.5 lbs, then multiply 4.60 by 7.5.
4.60x7.5= 34.5
For 7.5 lbs of walnuts will cost $34.50
