Mr. thomas spent $1,600 of his savings on a television set and 2/5 of the remainder on a refrigerator. he had 1/3 of his original amount of savings left. what was the cos of the refrigerator?

The amount spent on the refrigerator is $ 800 .

Step-by-step explanation:

Given as :

The amount spent on television = $ 1600

Le The total amount in the account = $ A

so, The amount left in account after spent on television = $ A - $ 1600

The amount spent on refrigerator = × ( A - 1600 )

The amount left in his saving account = × A

Now, According to question

A - ( 1600 +   × ( A - 1600 ) ) =   × A

Or, A -   × A = 1600 +   × ( A - 1600 )

Or, × A = 1600 + × A - × 1600

or,   × A -   × A = 1600 - 640

Or,   × A = 960

or,   × A = 960

∴ A =

I.e A = 3600

So, The amount in the saving account  is $3600

∵ , The amount spent on refrigerator = × ( 3600 - 1600 )

Or,  The amount spent on refrigerator = × 2000

I.e  The amount spent on refrigerator = $ 800

Hence The amount spent on the refrigerator is $ 800 . Answer

after simplifying it i got: -36.25 as my answer. hope that !

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
