Answer:
2 hours 30 minutes
Step-by-step explanation:
Given data
speed= 110mph
distance travelled= 275miles
Required
the time of travel
We know that
Speed= distance/time
time= distance/speed
time= 275/110
time=2.5 hours
Hence the time is 2 hours 30 minutes
4{8.2+3.7(4.4×8.8 -18.86)}=
4(8.2+3.7(38.72-18.86))=
4(8.2+(3.7)(19.86))=
4(8.2+73.482)=
(4)(81.682)=
326.728
We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:
All sides of the cube are squares with side, s. The area of one square is
A = s^2
The surface area of a cube is the sum of all areas of the sides. So
SA = 6 sides * s^2
SA = 6s^2
The volume of the cube is
V = s^3
The volume of the cube represents the total solid area of the cube which includes the space inside the solid.
A.) x (5 + x) = 5x + x^2
B.) 2 (5 + x) = 10 + 2x
