Answer:

The percent of change in the average amount received was 46% and this was a decrease.

Step-by-step explanation:

You can use the following formula to calculate the percentage of change:

% of change = ((New number-Original number) / Original Number) x 100

New number= 5,184

Original number= 9,600

Now, you can replace the values in the formula:

% of change = ((5,184-9,600) / 9,600) x 100

% of change = (-4,416 / 9,600) x 100

% of change = (-0.46) x 100

% of change = -46%

According to this, the answer is that the percent of change in the average amount received was 46% and this was a decrease.

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

The correct option will be :   14 years

<u><em>Explanation</em></u>

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.

What is the value of the expression when t is equal to 15? 2t divide 3
goblinko [34]
If we take the value of t to be 15 and then we perform the calculations of 2 times t divided by 3, we can express it all by two equations substituting the value given for t like so:
t = 15
2t/3 = 2(15)/3 = 30/3 = 10

What is 3/4 + 1/6 divided by 2/5 evaluated and simplified into a fraction?
BabaBlast [244]
3/4 + 1/6= the common denominator is 12
3x2/4x3 + 1x2/6x2= you must multiply the bottom values of the fraction to get 12 and whatever you multiply on the bottom you must do on the top as well
6/12 + 2/12= now you can add it
8/12
8/12 ÷ 2/5= you must multiply by the reciprocal
8x5/12x2=
40/36= this is the answer
10/9 (this is the simplified answer)
