The equation a=1/2(b^1+b^2)h can be determined the area, a, of a trapezoid with height, h, and base lengths, b^1 and b^2 Which are equivalent equations?

The complete question is as follows.

The equation a = can be used to determine the area , a, of a trapezoid with height , h, and base lengths, and . Which are equivalent equations?

(a)

(b)

(c) =

(d)

(e) = h

(a) ; (d) ;

Step-by-step explanation: To determine :

a =

2a = ()h

To determine h:

a =

2a =

= h

To determine

a =

2a =

Checking the alternatives, you have that and = h, so alternatives A and D are correct.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
