The variable y is directly proportional to the variable x. If y = 32 when x = 20, what is the value of x when y = 40?

elena55 [62]

Answer:

The Correct option is C ) 25

Therefore the value of x is 25 when y =40.

Step-by-step explanation:

Given:

Variable 'y' is directly proportional to the variable 'x'.

$\therefore y=kx$ ......Direct Variation

Where,

k = Constant of proportionality

To Find:

value of x = ? when y = 40

Solution:

First we need to find Constant of proportionality

When x = 20 and y = 32

Substituting the values we get

$32=k\times 20\\k=\dfrac{32}{20}=1.6\\\\k=1.6$

Now when k =1.6 , y = 40 then x will be

$40=1.6\times x\\\\x=\dfrac{40}{1.6}=25\\\\x=25$

Therefore the value of x is 25 when y =40.

Susan currently has an account balance of $1,336.60. Her initial deposit on the account was $820 and it earned 4.5% simple inter

emmasim [6.3K]

The correct option will be : 14 years

Explanation

Current account balance of Susan is $1,336.60 and her initial deposit was $820

So, the amount of interest earned $= 1336.60-820= 516.60$ dollar

Formula for Simple Interest is: $I= P*r*t$ , where $I$ is the amount of interest, $P$ is the initial amount, $r$ is the rate of interest in decimal and $t$ is the time duration in years.

Here, $I= 516.60, P= 820, r=4.5$ % $= 0.045$

Now according to the above formula, we will get...

$I= P*r*t\\\\ 516.60=820*0.045*t\\\\ 516.60=36.90*t\\\\ t=\frac{516.60}{36.90}= 14$

So, Susan has held the account for 14 years.
