30......................127,5
1.........................x
30x = 127,5
x = 127,5/30
x = 4,25
1 libra = 4,25 pizzas
4,25 pizzas.............1 libra
1 pizza.....................y
4,25y = 1
y = 1/4,25
y = 0,2353 libra (1 pizza)
1/8 de pizza = 0,2353/8 = 0,0294
Answer:
1400 square units
Step-by-step explanation:
The area can be computed by subtracting the areas of the white rectangles at three corners from the overall 60×30 rectangle.
The upper left corner white space is 10×10 = 100 square units.
The upper right and lower left white spaces are 15×10 = 150 square units each.
Then the shaded area is ...
60×30 -100 -2(150) = 1800 -100 -300 = 1400 . . . square units
_____
<em>Alternate solution</em>
You can extend each of the horizontal edges across the figure to divide it into three rectangles. From the top down, these have dimensions and areas of ...
35×10 +60×10 +45×10 = 10(35+60+45) = 10(140) = 1400 . . . square units
__
