Write the recursive function for this sequence.
8, 12, 18, 27

Answers

Answer 1

Answer: 8, 12, 18, 27

12 ÷ 8 = 1¹/₂
18 ÷ 12 = 1¹/₂
27 ÷ 18 = 1¹/₂

$a_(n) = r * a_(n - 1)$
$a_(n)} = 1(1)/(2)a_(n - 1)$

If the volume for 3-D polyhedra A is 300 cm3 and the volume for 3-D polyhedral B is 900 cm3. How many times bigger is the volume of pyramid B than pyramid A? Select one:
a. 3%
b. 30%
c. 300%
d. 3000%

Answers

Answer:

c. 300%

Step-by-step explanation:

In order to solve this problem you just have to divide the bigger polyhedral by the smaller polyhedral:

$(900 cm^(3) )/(300cm^(3))$

As this is equal to 3, you know that the bigger polyhedral is 3 times bigger than the smaller polyhedral so now you just make a rule of three, if an object that is 100% bigger than other is 1 time bigger, what would be the percentage of an object that is 3 times bigger?

$(1)/(100)=(3)/(x)$

Once you clear the X the equation would look like this:

$x=(3*100)/(1)$

$x=300$

Hello Marie,

V(B)/V(A)=900/300=3=300/100=300%

The margin of error for the population mean is C) 0.34. Hope that helps.

Answer:from what I did it was 0.66

Step-by-step explanation:

25% of what nember is 19

Answers

You would do 0.25x (x is the unknown total number)=19. It is because of is a multiply sign, so 0.25*x=19. Divide both sides by 0.25 and you get 76 as your answer.

25% OF WHAT = 25% OF X = .25 OF X = .25X
.25X = 19
X = 19 DIVIDED BY .25
X = 19 DIVIDED BY 1/4
X = 19 X 4
X = 76
