Answer:
3/2 cm^2 or 1.5 cm^2
Step-by-step explanation:
Remark
This is another one of those very poorly design questions where a lot is taken for granted. There is nothing to show the the black square has an area of 1/4 square cm. or the white square is 1/2 cm^2. You are left to speculate, and you should never have to guess a dimension from a diagram.
That said here are the assumptions
- Each side of the square = Perimeter / 4. That's because the perimeter is 8 and each of the 4 sides is 2 cm. because 8/4 = 2
- That's the only thing that you can conclude for certain.
- It looks like the white rectangles have a length that totals 2. Therefore each one must be 1 cm long.
- The width of the white square must be 1/2 the width of a side divided by 2. That's because The grey square takes up 1/2 the with of the side and the white square is 1/2 of what is left over.
White square area = L * W
L = 1 (which comes from 1/2 of 2)
W = 1/2
Area = 1 * 1/2 = 1/2
There are two them them so their area = 1
The black squares are 1/2 * 1/2 = 1/4 square cm. There are two of them so their total area = 1/2 square cm.
Total of the white and black squares = 1 + 1/2 = 1 1/2 or 3/2 square cm.
Answer: The value is 18.
Step-by-step explanation:
Since we already know what <em>p, q, and r</em> equal, we can use what we know and plug in the numbers:
p=7, q=5, and r=3,
p2=7*2=14
q2=5*2=10
r2=3*2=6
In conclusion, 14+10-6=18
The value of p2+q2-r2 is 18.
15+8+8=31 (3 tickets)
2480/31= 80

Answer:
Part a) The measure of the missing angle is 
Part b) The triangle of the figure is a right triangle
Part c) The triangle of the figure is a scalene triangle
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle is equal to 
so
Let
x------> the missing angle
we know that

solve for x

The triangle of the figure is a right triangle --------> by its angles
Because the triangle has an angle measure of 
The triangle of the figure is a scalene triangle --------> by its sides
Because the three angles and the three sides measures are different
13 times 6 times 2.5 equals 195 square inches
