tia_tia [17]

Answer:

El período paleolítico corresponde a \frac{332}{333} de la época prehistórica.

Step-by-step explanation:

En primer lugar, se determina la extensión de tiempo, medida en años, tanto de la época prehistórica como el período paleolítico: (Nótese que el signo negativo significa a.C.)

Época Prehistórica

\Delta T = -2500-(-2500000)

\Delta T = 2497500\,years

Período Paleolítico

\Delta t = -10000 - (-2500000)

\Delta t = 2490000\,years

La fracción de la época prehistórica que corresponde al período paleolítico es:

r = \frac{\Delta t}{\Delta T}

r = \frac{2490000\,years}{2497500\,years}

r = \frac{332}{333}

El período paleolítico corresponde a \frac{332}{333} de la época prehistórica.

Option B. 2.75

Step-by-step explanation:

It has been given in the question that a wedge has a width of 2 cm and a slope of 5.5 cm.We have to calculate the mechanical advantage of the given wedge.

We know the formula to calculate the mechanical advantage of the wedge

Mechanical advantage = Length of slope/Thickness of the widest end

What is the volume of this rectangular prism?
Fynjy0 [20]

Answer: V≈5.21 cm³

Step-by-step explanation:

To find the volume of a rectangular prism, you multiply the length, width and height.

V=wlh

Since we were given the length, width and height, we can directly multiply them together.

V=\frac{5}{2} *\frac{5}{3} *\frac{5}{4}             [multiply]

V=\frac{125}{24} =5.21 cm^3

Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.
