Answer:

$4,457,391.19

Step-by-step explanation:

The sum of n terms of a geometric sequence with common ratio r and initial value "a" is ...

S = a(r^n -1)/(r -1)

Here, your growth factor is r = 1 +6% = 1.06. So, the sum of expenses over 35 years will be ...

S = $40,000(1.06^35 -1)/(1.06 -1) = $4,457,391.19

Answer:

3,160,080

Step-by-step explanation:

The first place can be taken by any one of the 22 students.
The second place can be taken by any one of the remaining 21 students.
The third place can be taken by any one of the remaining 20 students.
The fourth place can be taken by any one of the remaining 19 students.
The fifth place can be taken by any one of the remaining 18 students.

<em>This basically means multiplying 22, 21, 20, 19, and 18. Or, the number of permutation of 22 things taken 5 at a time.</em>

The answer is 22*21*20*19*18 = 3,160,080

<em>Using formula $nPr=\frac{n!}{(n-r)!}=\frac{22!}{(22-5)!}=\frac{22!}{17!}=(22*21*20*19*18)=3,160,080$ </em>

One angle is twice another angle. The sum of the angles is 90 degrees. How many degrees are in each angle. Please explain.

Natali [406]

One angle has 60 degrees, the other angle has 30 degrees.

60 divided by 30 = 2.

and 60 + 30 = 90.

Carrie runs 11.5 miles and five hours at a study pi runs 11.5 miles in five hours at a steady pace how long does it take her to

alukav5142 [94]

dividing 11.5 by 5 gives you the unit rate, then you just multiply that answer by 2 and you should be okay

A square with an area of 196 ft2 is reduced by a factor of 1/4. How long the new sides of the square?

Answer:

$49$

Step-by-step explanation:

<h2><u>Lesson : Reducing by factors:</u></h2><h2><u /></h2>

Given :

$196ft^2$

$Reduced * factor * of * \frac{1}{4}$

When you have to reduce a number by a certain factor, you must divide the area with the amount that it is reducing from, therefore,

$\frac{196}{4}$

$49$
