The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.
Area of Square + 4*Area of Triangle = SA
Area of Square:
2^2=4
Area of Triangle:
0.5*2*3=3
SA=4+4*3
SA=16 meters squared
Let the consecutive even integers be x and (x+2).
x + (x + 2) = 106
2x + 2 = 106
2x = 104
x = 52
Thus the two integers are 52 and 54.
Answer: 5.5hours
Step-by-step explanation:
Total distance = 226miles
Total time = 7 hours
Let b represent total time spent while walking.
Distance (walking) = 4b
Distance ( riding) = 40(7-b)
Total distance 226 = 4b + 40(7-b)
226 = 4b + 280 - 40b
226 = 280-36b
b = 54/36
b = 1.5hours
Amount of time spent walking = 1.5hours
Amount of time spent riding = 7-1.5 = 5.5hours
Amount of time spent on bicycle = 5.5hours
Answer:
x = 31.8
Step-by-step explanation:
From the picture attached,
By applying Pythagoras theorem in right ΔADC,
AC² = AD² + CD²
(22)² = AD² + (16)²
AD² = 484 - 256
AD = √228
= 2√57
Now we apply Pythagoras theorem in right ΔADB,
AB² = AD² + DB²
x² = 228 + (44 - 16)²
x² = 228 + 784
x² = 1012
x = √1012
= 31.81
≈ 31.8
