Answer:
120 miles
Step-by-step explanation:
Step up a portion. Here, 1 cm is to 1.5 cm as 80 mi is to x mi
1/1.5 = 80/x
Now solve for x by cross multiplying
x = 120
Answer:
Area = 25.12 square units.
Perimeter = 20.56 units
Step-by-step explanation:
If you are looking for area, here goes:
Area of circle = π * r^2
Area of semi-circle = S = (1/2) *π * r^2
S = (1/2)*π*(4^2) = (1/2)π*16 = 8π square units = 25.12 square units
Or if you are looking for the perimeter:
Circumference C = 2*π*r
Half-circumference = (1/2)C = (1/2)*2*π*r = π*r = π*4
Perimeter of semi-circle = 4 + 4 + 4π = 8 + 4π
14(3+1) - (3 - 7)
"double" - times by 2
"and" - addition
when using " first second and third" you just have to assign the numbers by the way it comes in the problem...
first number - 7
second number - 3
third number - 1
If it stays as fraction the answer would be 7/14
There is no way I can answer this without the graph
