Abcd is a trapezoid. segment ab = 1 cm and segment cd = 5 cm, and the area = 7.5 cm2. what is the altitude of the trapezoid?

2.5 cm

Step-by-step explanation:

We know that area of trapezoid A = , where a and b are the opposite sides of trapezoid and h is the altitude of the trapezoid.

Given: AB = 1 cm and  CD = 5 cm, and the area = 7.5 square cm.

By the name of trapezoid we can see that AB and CD are opposite sides of trapezoid, then

Area of trapezoid=

Hence, the altitude of the trapezoid = 2.5 cm

109 is the nearest whole number/final answer! : )

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
