28 in. Because 7x7=49 (sides of a square are equal) so you know that each side is 7 in, now multiply by 4 (for the number of sides) to find the perimeter.

The lines shown below are perpendicular. If the green line has a slope of 2/5 what is the slope of the red line
Ksenya-84 [330]
In this item, we are not given with the figure but knowing that these lines ought to be perpendicular then we will be able to derive the relationship between the slopes of the line. 

The slopes of the perpendicular line are the negative reciprocals of one another. If we represent the slopes of the lines as m₁ and m₂, the relationship can be written in the form,
           (m₁)(m₂) = -1

We are given with one of the slopes. To determine the value of the second slope then,
            m₂ = -1/m₁
            m₂ = -1/(2/5)
            m₂ = -5/2

<em>ANSWER: m₂ = -5/2</em>

What is the area of a rectangle with side lengths of 5 12 foot and 2 3 foot
vazorg [7]

Answer:

3 2/3ft²

Step-by-step explanation:

Area of a rectangle = Length × Width

Given

Length = 5 1/2 foot

Width = 2/3foot

Substitute

Area of the rectangle = 5 1/2 × 2/3

Area of the rectangle = 11/2×2/3

Area of the rectangle = 22/6

Area of the rectangle = 11/3

Area of the rectangle = 3 2/3ft²

Convert (CAB) 16 to decimal<br><br>need help asap
Mrrafil [7]

Remark

So CAB is a base 16 number? I hope that's correct. I'll treat it that way. If I am incorrect, please leave a note and I'll modify my answer accordingly.

Expand

A = 10 in decimal

B = 11  in decimal

C = 12 in decimal

B is the "units" value in decimal it is 11

A is the "tens" value or 12 place and in decimal you would get 12 * 10 = 120

C is the "hundreds" value or 12^2 place and in decimal you would get 144*12 =1728

Now you need to all all three results together. 11 + 120 + 1728 = 1850

Answer

(CAB)_16 = 1850 in decimal
