Answer:
132 cm²
Step-by-step explanation:
This is a composite figure, so we want to find the area of the top rectangle and the bottom trapezoid and then add those together.
The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. Here, the length is l = 4 and the width is w = 7, so the area is:
A = lw
A = 7 * 4 = 28 cm²
The area of a trapezoid is denoted by: A = 
, where b1 and b2 are the bases and h is the height. Here, the two bases are 7 and 19 and the height is h = 8. So, the area is:
A =
A = 
cm²
Add these together:
28 + 104 = 132 cm²
Answer:
Based on what I know the answer is 28.
Step-by-step explanation: I know that it is 28 because I listed all of the factors on a piece of paper and matched them all up and saw that the answer was 28.
Answer:
Step-by-step explanation:
From the question we are told that
Width of circular path 
Inner Diameter 
Outer diameter 
(inner diameter + 2 circular path width)
Generally the equation for inner circumference of the circle 
is mathematically given by
Generally the equation for outer circumference of the circle 
is mathematically given by
Generally the difference in length of the two circumference 
is mathematically given by
Answer:
Inconsistent
Step-by-step explanation:
We are given the equations;
0.3y=0.6x+0.3
1.2x+0.6=0.6y
Assuming we are required to determine whether the system of equations are consistent or inconsistent
We are going to use substitution
Making y the subject;
Equation 1: 0.3y=0.6x+0.3
Dividing both sides by 0.3
y = 2x + 1
Equation 2: 1.2x+0.6=0.6y
Dividing both sides by 0.6
y = 2x + 1
This means both equations are similar and we can't get a solution.
Therefore, the system of equations is inconsistent.
