Answer:

Using the formula provided, the value of that investment after 10 years is

A = P(1 + r/n) ^nt

= 4500 x (1 + (4/100)/4)^(10 x 4)

= 4500 x (1.01)^40

= 6699.89$

La suma de dos números es 14 añadiendo 1 al mayor se obtiene el doble del menor cuáles son los dos números. si puede ser explica

elena-s [515]

Answer:

The two numbers are 9 and 5.

Step-by-step explanation:

The question is:

The sum of two numbers is 14, adding 1 to the greatest gives twice the smallest which are the two numbers. if it can be explained please

Solution:

Denote the two numbers by <em>x</em> and <em>y</em>.

It is provided that:

$x+y=14...(i)$

Also,

$x+1=2y\\\Rightarrow x-2y=-1...(ii)$

Solve the equations (i) and (ii) by the substitution method as follows:

In equation (ii) substitute <em>x</em> = 14 - y and solve for <em>y</em>:

$x-2y=-1\\14-y-2y=-1\\-3y=-1-14\\-3y=-15\\y=5$

Substitute <em>y</em> in equation (i) and solve for <em>x</em> as follows:

$x+y=14\\x+5=14\\x=14-5\\x=9$

Thus, the two numbers are 9 and 5.

Two-thirds of the students in Hannah's homeroom plan to do some volunteering this summer. Of these students,3/5 plan to voluntee

Annette [7]

Answer:

2/5 of the students

Step-by-step explanation:

Let the total number of students be x. Two-Thirds of the students plan to do some volunteering. Two-Thirds in fraction can be written as 2/3. So the portion of the students which plan to do some volunteering is:

$\frac{2x}{3}$

From these students, 3/5 plan to volunteer at community center. So the students who plan to volunteer at community center will be:

$\frac{2x}{3} \times \frac{3}{5}\\\\ = \frac{2x}{5}$

This means, among x students, 2/5 of the students plan to volunteer at the community center this summer.
