Answer: r = 2/3

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = 36

The 4th term is 32/3

n = 4

Therefore,

T4 = 32/3 = 36 × r^(4 - 1)

32/3 = 36 × r^3

Dividing both sides if the equation by 36, it becomes

32/3 × 1/36 = r^3

8/27 = r^3

Taking cube root of both sides of the equation, it becomes

(8/27)^1/3 = r^3 × 1/3

r = 2/3

every sixth visitor to an animal shelter gets a free animal calendar every twentieth visitor gets a free animal toy. Which visit
Akimi4 [234]
Here we have a case of the least common multipl(lcm) of 6 and 20.
Prime numbers 2,3,5,7,11,13,17,19... (natural numbers greater than 1 that has no positive divisors other than 1 and itself) .
lcm(6,20)= 6 20 | 2
                  3 10 | 3
                  1 10 | 2
                       5 | 5
                       1
2*3*2*5=60 The first one to get both calendar and the animal toy will be 60th.
 
Explenation: First we look for the smallest prime number with wich 6 and 20 can be devided by. That is 2. Next is 3. Since 10 is not divisible by 3, we only copy it. Under the 6 we got 1, wich is our goal. Now we continue to devide 10 by prime numbers till we also get 1. We now multiple all divisors and we get the least common multiple.

Your gross pay is $2,759.00. your involuntary deductions are fica (7.65%), federal withholding (12%), and state withholding (7%)
max2010maxim [7]
Gross pay = $2,759.00
Total deductions = 7.65%+12%+7% = 26.65% = 0.2665

By thumb rule, rent and other fixed expenses ≤ 28% of Monthly gross salary

Therefore,
Allowed housing and fixed expenses = 0.28*2,759 = $772.52

Then, a. is the correct answer.

How do i solve functions?
Maksim231197 [3]
Most quadratic functions(which is what you have there, to a degree of 2) are solved using factoring and the zero product law. If you can not factor then you have to use the quadratic formula or graph it. However this one can be factored.
It's pretty simple to just factor it by inspection but I use the chart method, if you know decomposition that works as well.
Factoring gives us,
(2x + 1)(x - 3) = 0
Then you set each factor to 0 and solve for x,
2x + 1 = 0
2x =  - 1
x =  \frac{ - 1}{2}
And the second one,
x - 3 = 0
x = 3
The solutions to this equation are
x = -1/2, 3
