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.

You may find that problems that are simply the addition of numbers will be avoided by many answerers.

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:

<em>First, we need to know the formula to calculate volume:</em>

volume=height XBase area

<em>if we change to our equations to the values we know:</em>

16.328 = 3.14XB

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

\frac{16.328}{3.14} =B

<em>We calculate the operation=</em>

\frac{16.328}{3.14} =5.2

<em>And the answer is 5.2 cm²</em>

<em>Let me know if you have any question :D</em>

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
