Answer:

31.1 meters

Step-by-step explanation:

he uses 22 pieces of slate each 1.3 meters long so we multiply 22*1.3=28.6

then he adds one piece of slate which is 2.5 meters long so we add 2.5 to 28.6

2.5+28.6=31.1

Answer:

31.1 meters

Step-by-step explanation:

To find the total length of all the pieces, you add up the lengths of the individual pieces.

Rather than add 1.3 twenty-two times, most people use multiplication.

The sum of the lengths of the shorter pieces is ...

22 × 1.3 m = (22×1.3) m = 28.6 m

Adding that to the length of the one longer piece, we get the total length:

28.6 m + 2.5 m = 31.1 m

The path is 31.1 m long.

The volume of a rectangular prism is 16.328 cm³. The height is 3.14 cm.

Ghella [55]

Answer:

The area of the base is = 5.2 cm²

Step-by-step explanation:

First, we need to know the formula to calculate volume:

$volume=height XBase area$

if we change to our equations to the values we know:

$16.328 = 3.14XB$

Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:

$\frac{16.328}{3.14} =B$

We calculate the operation=

$\frac{16.328}{3.14} =5.2$

And the answer is 5.2 cm²

Assume the exponential growth model A(t)equals=Upper A 0 e Superscript ktA0ekt and a world population of 5.95.9 billion in 2006

Whitepunk [10]

Answer:

1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.

Step-by-step explanation:

We are given the following in the question:

The exponential growth model is given by:

$A(t) = A_0e^{kt}$

where k is the growth rate, t is time in years and $A_0$ is constant.

The world population is 5.9 billion in 2006.

Thus, t = 0 for 2006

$A_0 = 5.9\text{ billions}$

We have to find the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.

Putting these values in the growth model, we have,

$24 = 5.9e^{100k}\\\\k = \dfrac{1}{100}\ln \bigg(\dfrac{24}{5.9}\bigg)\\\\k = 0.01403\\k = 0.01403\times 100\% = 1.4\%$

1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.

What is (99/100)^101 times (100/99)^100?

sineoko [7]

Answer:

99/100

Step-by-step explanation:

First of all recall that

$a^n\cdot b^n =(ab)^n$

Now we we will try to apply that formula for $a=99/100$ and $b=100/99$ .

First rewrite $(99/100)^{101}=(99/100)\times (99/100)^{100}$

Now

$(99/100)\times (99/100)^{100}\times (100/99)^{100}\\=(99/100)\times ((99/100)\times (100/99))^{100}\\=(99/100)\times 1^{100}\\=(99/100)\times 1\\=99/100$

Derman says, "I'm halfway through reading my book.if I read another 84 pages, I'll be two thirds of the way through my book." ho

Licemer1 [7]

I would say 504 basing it off of converting 2/3 into 4/6 and used sets of 84 to each be 1/6
