You turn 4/5 to 8/10 to get equal denominators and add the numerators together to get 16/10, or 1 6/10 which is reduced to 1 3/5.

I need help please!!! 30 points

Umm, I don't feel like typing (too lazy and tired to do that lol) so I will attach a written file.

BTW-

Radius is HALF the Diameter.

Diameter is that straight line that goes across the center of the circle.

Radius is basically a line from the center of the circle to any of the side of the circle.

Circumference is basically the perimeter of the circle, or the border or it. It is the Diameter times pi (it said to use 3.14 for pi). It can also be 2 times the Radius times pi (3.14) (since Radius is half the Diameter).

Area is the region inside the circle. Area is the Radius squared (to the power of 2, whatever) times pi (simplified as 3.14).

Okie, now the answers.

^^^Too lazy to put the unit lol.

If a sports car is traveling at 95 miles per hour, how long would it take the sports car to overtake a family car traveling at 3

levacccp [35]

Distance = speed * time
d = st

The sports car travels d distance for t time at speed, s, 95 mph until it overtakes the family
car.
The equation for the sports car is
d = 95t

The family car travels the same distance, d, but since it left 4.5 hours earlier than the sports car, it travels for t + 4.5 time until it is overtaken. It travels at speed, 35 mph.
The equation for the family car is
d = 35(t + 4.5)

We solve the two equations as a system of equations.

d = 95t
d = 35(t + 4.5)

Since d = d, set the right sides of the equations above equal to each other.

95t = 35(t + 4.5)

95t = 35t + 157.5

60t = 157.5

t = 2.625

The answer is 2.625 hours, or 2 hours, 37 minutes, and 30 seconds.

Check:
In 2.625 hours, the sports car travels: 95 mph * 2.625 h = 249.375 miles
The family car traveled 2.625 hours plus the extra 4.5 hours, or 7.125 hours.
In 7.125 hours, the family car travels 35 mph * 7.125 h = 249.375 miles.
The cars have traveled the same distance 2.625 hours after the sports car left, so our answer is correct.
