Answer:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
Step-by-step explanation:
Remember that the velocity v equals the distance d between time t.
and 
The distance that Hal travels when traveling with the wind is:
miles
Where v is the speed of Hal and c is the wind speed.
The distance when traveling against the wind is:
miles
Now we solve the first equation for v
Now we substitute the value of v in the second equation and solve for c
Then:
The maximum speed of Hal's airplane in still air is:
The speed of the wind
Answer:
9 ft = 9 × 12 = 108 in
ratio is 1:108
Step-by-step explanation:
The correct answer would be B E'F' and EF are equal in length.
Answer:
84 cm²
Step-by-step explanation:
Surface area of the polyhedron = the sum of the areas of each parts of the net = area of 2 triangles + area of each of the 3 rectangles
Area of 2 triangles:
Base = 4 cm
Height = 3 cm
Area of the 2 triangles = 2(½*base*height)
= 2(½*4*3) = 4*3 = 12 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 4 cm
Area = length * width = 24 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 5 cm
Area = length * width = 30 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 3 cm
Area = length * width = 18 cm²
Surface area of the polyhedron = 12 + 24 + 30 + 18 = 84 cm²
Well the factors of "72" is→ 1,2,3,4,6,8,9,12,18,24,36,72
To find the factor(s) "72" just write out the muliples that equals 72
