Evaluate abc if a = -2/5 , b = 20/32, and c = -4/10 . Express your answer as a fraction in simplest form. *
A.4/40
B.-1/10
C.160/1600
D.1/10

Remember that when multiplying fractions, we multiply everything on the top and everything on the bottom.

a * b * c

(-2 / 5) * (20 / 32) * (-4 / 10)

(-2 * 20 * -4) / (5 * 32 * 10)

160 / 1600

1 / 10

Correct D. 1/10

Hope this helps!! :)

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
