m) 2.597= 2 .0+ 0.5+ 0.09+0.007

Step-by-step explanation:

A medida que nos alejamos del punto decimal, el número de ceros aumenta y el dígito se mueve hacia la derecha.

Los valores después del decimal se denominan décimas, centésimas y milésimas.

a) 1.585 =1.0 + 0.5+ 0.08+0.005

b) 1.059= 1 .0+ 0.0+ 0.05+0.009

c) 2.440 = 2.0 + 0.4+ 0.04

d) 5.329= 5.0 + 0.3+ 0.02+0.009

e) 8.801 = 8.0 + 0.8+ 0.00+0.001

f) 9.999= 9.0 + 0.9+ 0.09+0.009

g) 3.718 = 3.0 + 0.7+ 0.01+0.008

h) 6.840= 6.0 + 0.8+ 0.04

i) 7.504 = 7.0 + 0.5 +0.004

j) 5.225 = 5.0 + 0.2+ 0.02+0.005

1) 4.063 = 4.0 + 0.0+ 0.06+0.003= 4+0.06+0.003

m) 2.597= 2 .0+ 0.5+ 0.09+0.007

The values after the decimal are called tenths hundredths and thousandths

Describe the three base materials in soil in terms of porosity and permeability.
777dan777 [17]

<u>Porosity:</u>

  1. Porosity is an intrinsic property of every material.
  2. It refers to the amount of empty space within a given material.
  3. In a soil or rock the porosity (empty space) exists between the grains of minerals.
  4. The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material.
  5. We measure porosity by the percentage of empty space that exists within a particular porous media.

<u>Permeability:</u>

  1. Permeability is another intrinsic property of all materials and is closely related to porosity.
  2. Permeability refers to how connected pore spaces are to one another.
  3. If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them.

A construction worker drops a hammer from a height of 25 m.
Snezhnost [94]

Answer:

Time at which the hammer reaches the ground is 2.3 seconds.

Step-by-step explanation:

We are given the formula as, h(t)=-4.9t^2+v_{o}+h_{o}.

It is known that, when height i.e. h_{o}=25 meter, then velocity v_{o}=0 m/sec.

So, we get the formula as, h(t)=-4.9t^2+25.

Now, when the hammer hits the ground, the height h_{o}=0 meter.

Thus, we have,

h(t)=-4.9t^2+25

⇒ 0=-4.9t^2+25

⇒ 4.9t^2=25

⇒ t^2=5.1

i.e. t= ±2.3 sec

Since, time cannot be negative.

So, t= 2.3 sec

Hence, the time at which the hammer reaches the ground is 2.3 seconds.
