Answer:
42.9
Step-by-step explanation:
The range is the difference between the highest and lowest numbers
71.8-28.9=42.9
18.75/75=(75/75) -
p =(75-18.5)/75
p=56.5/75
p=0.75(3recurring)
Answer:
132 cm²
Step-by-step explanation:
Consider the shape as a trapezoid with a rectangle added on top.
The area of the trapezoid is (7+19)/2 × 8 =104
The area of the rectangle is 7×4 = 28
Add the two areas: 104+28= 132
OR consider the shape as a tall rectangle with the two triangles added to the sides.
The area of the rectangle is 7(4+8) = 84
The area of the triangles is 8(19-7)/2= 48
[Each triangle is 24 cm²]
Add those areas
84+48=132
Same result: 132 cm²
I’m not that smart... but let me use first as example.. 240 divided by 4
