The total number of pennies on Rows 1-4 (the first 32 squares) is 4,294,967,295 or 2³².

<h3>What is geometric progression?</h3>

A geometric progression is the series of numbers such that the ratio of any two consecutive numbers of the series is the same.

If we look closely at the problem we will understand that on each of the square boxes the number of pennies will get double from the previous one therefore, we can say that it is forming a geometric progression where the first term of the sequence is 1, while the common ratio is of 2. thus,

The total number of pennies on Rows 1-4 (the first 32 squares) is the sum of the geometric progression for the first 32, terms, therefore,

S_n = a_1(\dfrac{r^n-1}{r-1})

Now, as we know that the first term of the series is 1, while the common ratio(r) is 2, and the number of terms(n=32). Thus, the sum can be written as,

S_n = a_1(\dfrac{r^n-1}{r-1})\\\\S_n = 1(\dfrac{2^{32}-1}{2-1})\\\\S_n = 4,294,967,295

The number can also be written as,

S_n = 4,294,967,295\\\\S_n = 2^{32}

Hence, the total number of pennies on Rows 1-4 (the first 32 squares) is 4,294,967,295 or 2³².

An oil tank has a capacity of 45 gallons. At the beginning of October it is 80% full. At the end of October it is 1/3 full. How
Yakvenalex [24]
Capacity of the tank = 45 gallon
At the beginning of Oct., amount of oil in the tank = 45*0.8 = 36 gallons
At the end of Oct., amount of oil in the tank = 45*1/3 = 15 gallons
So, amount of oil used during Oct = (36-15) = 21 gallons

Consider this sequence: -81, -54, -36, -24, … .
N76 [4]
If it is geometric then
if the terms are a,b,c,d then
b/a=c/b=d/c
so
-54/-81=-36/-54=-24/-36?
2/3=2/3=2/3

and that is the common ratio

it is geomertic and common ratio is 2/3

Vanyuwa [196]

Answer:

El área de la finca que está sembrada por café es 360 m².

Step-by-step explanation:

La finca de Federico tiene tiene un área de 576 m². \frac{3}{8} de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:

576 m²* \frac{3}{8} = 216 m²

Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:

576 m² - 216 m²= 360 m²

<u><em>El área de la finca que está sembrada por café es 360 m².</em></u>
