Find the area of a trapezoid with bases 14 cm and 18 cm and height 10 cm. a: 126 cm2b: 160 cm2c: 140 cm2d: 180 cm2

The answer is B, 160 cm2

Step-by-step explanation:

To find the area of a trapezoid we have to use the following equation:

A= 0.5*(b1*b2)*h

a= area

b1: base 1

b2: base 2

h: height

Then,

A= 0.5*(14cm+18cm)*10cm = 160 cm2.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
