Given that y varies directly with x, find the equation of direct variation. x is 14 when y is 12

Sergeu [11.5K]

Step-by-step explanation:

x×k = y

14×k = 12

k = 12/14 = 6/7

so, the equation is

x × 6/7 = y

y = 6x/7

y = 6/7 x

Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the

irga5000 [103]

Hello,

Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3

Proof: a+b+c=15.9+5.3+31.8=53

The second number is 5.3

Answer:

The Amount of money in the account after 20 years $22,416.

Step-by-step explanation:

Given as :

The principal deposited into account = $4000

The rate of interest = 9% compounded annually

The time period for deposit = t = 20 years

Let the amount into account after 20 years = $A

now, According to question

From compound Interest method

Amount = principal × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

Or, A = $4000 × $(1+\dfrac{\textrm r}{100})^{\textrm t}$

Or, A = $4000 × $(1+\dfrac{\textrm 9}{100})^{\textrm 20}$

Or, A = $4000 × $(1.09)^{20}$

or, A = $4000 × 5.604

So, The amount in account after t years = A = $22,416

Hence, The Amount of money in the account after 20 years $22,416. Answer
