Exactly 640 acres are in one square mile. how many square meters are in 2.2 acres

Mathematics

Tasya [4]3 years ago
3 0
640 acres = 1 square mile

So we can say 1 acres = \frac{1}{640} square mile
                          
So in 2.2 acres = 2.2 *  \frac{1}{640} square mile
                         
                         = 0.0034375 square mile

In general one mile = 1609.344 meters

So one square mile = 1609.344 * 1609.344 square meter

                                = 2589988 square meter

So 0.0034375 square mile = 0.0034375 * 2589988
                                           = 8903.08375 square meter.

Nadir saves $1 the first day of a month, $2 the second day, $4 the third day, and so on. He continues to double his savings each
zheka24 [161]

ANSWER

$16,384

EXPLANATION

From the question we have that,

Nadir saves $1 the first day of a month, $2 the second day, $4 the third day, and so on.

This forms a geometric sequence,

1,2,4,...

The first term of this sequence is

a = 1

The common ratio is

r =  \frac{2}{1}  =  \frac{4}{2}  = 2

The general term of a geometric sequence is given by the formula:

f(n) = a {r}^{n - 1}

To find the 15th term, we plug in a=1, r=2 and n=15.

f(15) = 1 {(2)}^{15 - 1}

f(15) =  {2}^{14}

f(15) = 16384

The amount he will save on the 15th day is $16,384

How do you do the second part of the problem?
Sveta_85 [38]

Answer:

8

Step-by-step explanation:

According to the Alternating Series Estimation Theorem:

│aₙ₊₁│≤ ε

1 / (4 (n + 1)⁴) ≤ 0.00005

4 (n + 1)⁴ ≥ 20000

(n + 1)⁴ ≥ 5000

n + 1 ≥ 8.41

n ≥ 7.41

n must be an integer, so n ≥ 8.

The floor of Cara's living room is 10 feet by 14 feet. What is the area, in square feet, of the largest circular rug that can fi
Rus_ich [418]

Answer:

78.5\ ft^{2}

Step-by-step explanation:

we know that

If the floor of Cara's living room is 10 feet by 14 feet

then

the diameter of the larger circular rug that can fit in Cara's living room is equal to 10 feet

<em>Find the area of the circular rug</em>

The area of the circle is equal to

A=\pi r^{2}

we have

r=10/2=5\ ft ----> the radius is half the diameter

\pi=3.14

substitute the values

A=(3.14)(5)^{2}=78.5\ ft^{2}

7.EE.1.1
victus00 [196]

Answer:

-0.55n - 0.05

Step-by-step explanation:

You can start by distributing:

(0.25n - 0.3) - (0.8n - 0.25)

0.25n - 0.3 - 0.8n + 0.25

Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)

-0.55n - 0.05

You can look for the number 16 on the x-axis. (bottom line) and put a finger there. Then, look for 19 on the y -axis (left line) and put a finger there. Trace your left finger to the right and your right hand up until they meet. That is (16,19)
