This is calculated using the formula of: A = Pe(rt), where A is the total amount, P is the principal amount, e is mathematical constant approximately equal to 2.71828, r is the rate of interest, then t is the time in years.

Given we have the P as $12,000, r is 0.064 and t is 12, we expressed these values to the formula as;

A = Pe(rt)
A = 12,000.e(0.064 x 12)
A = 12,000 x 2.71828e
A = 12,000 x 2.155
A = $25,860

Therefore the money that Ann will have in 12 years is $25,860.

X - 2/5= 7<br> find out what x is
nalin [4]

Answer:

see below

Step-by-step explanation:

x - 2/5= 7

Add 2/5 to each side

x - 2/5 + 2/5 = 7+2/5

x = 7 2/5

or if

( x-2) /5 = 7

Multiply each side by 5

(x-2) /5 *5 = 7*5

x-2 = 35

Add 2 to each side

x-2+2 = 35+2

x = 37

Suppose 56% of students chose to study Spanish their senior year, and that meant that there were 98 such students. How many stud
Varvara68 [4.7K]

The number of students who chose not to study Spanish in their senior year is 124.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given that

56% Students studied Spanish, which means 44% did not study Spanish.

In mathematics, a ratio shows how many times one number contains another.

Hence if the ratio is:

56 : 44 = 14:11

Then, the number of students who did not study Spanish is:

(14/11)×98 = 124.

Therefore the correct answer is 124.
