Answer:
Option A is correct
3.33 ft wide should the metal piece be.
Step-by-step explanation:
Area of rectangle(A) is given by:
.....[1]
l is the length and w is the width of the rectangle respectively.
As per the statement:
One more rectangular-shaped piece of metal siding needs to be cut to cover the exterior of a pole barn. The area of the piece is 30 ft²
⇒A = 30 ft²
It is also given that the length is 1 less than 3 times the width
⇒
ft
Substitute the given values in [1] we have;
Using distributive property: 
then;
We can write this as:
Factorize this equation:
Split the middle term we have;
⇒
⇒
By zero product property we have;
and w+3 = 0
Since, w cannot be negative;
so,
ft
Therefore, to the nearest hundredth of a foot, 3.33 ft wide should the metal piece be.

In the pic3 you can calculate "x" from the equation:
Answer:
0.027,1/5,23%,1/4, 0.29
Step-by-step explanation:
Please mark brainliest and have a great day!
x + x + 2 + x + 4 <= 126 (where x is the first of the numbers)
3x <= 120
x <= 40
So the numbers are 40 , 42 and 44.
Answer:
Step-by-step explanation:
Mid point of two points is given as
Let Point 1 be(x1,y1)
And point 2 be (x2,y2)
Then, mid point is given as
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
So, given that,
Point 1 =(4,5)
Then, x1=4 and y1=5
Point 2=(1,2)
Also, x2=1 and y2=2
Then, applying the formulae
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
M = [ (4+1) / 2 , (2+5) / 2 ]
M = [ 5 / 2 , 7 / 2 ]
Then, the midpoint is
M=(5/2, 7/2)
To decimal point
M=(2.5 , 3.5)
To mixed fraction
M=(2½, 3½)
(x, y)=(2½, 3½)
