Answer:

70 degrees

Step-by-step explanation:

cos^{-1} \frac{3.4}{10}=x

This implies that:  cos x=  \frac{3.4}{10}Recall: cos x=\frac{adjacent}{hypotenuse}

From the diagram

Angle CAB,  x=cos^{-1} \frac{3.4}{10}=70.1 degrees=70 (to the nearest degree)

Una fabrica produce 132 litros de yogurt diarios .Con 49 litros se llenan botellas de 0,25litros xada una y con el resto que que
nordsb [41]

Answer:

z = 362\,botellas

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)

La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:

x = \frac{49\,L}{0.25\,\frac{L}{botella} }

x = 196\,botellas

La cantidad remanente de yogurt es:

V_{r} = 132\,litros - 49\,litros

V_{r} = 83\,litros

Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:

y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }

y = 166\,botellas

Finalmente, el total de botellas a llenar es:

z = 196\,botellas + 166\,botellas

z = 362\,botellas

If 35% of a natural area is to be developed, leaving 500 acres untouched, how many acres are to be developed?
xxTIMURxx [149]
Given that the 35% of area has been developed, the percentage of land that has not been developed is:
100-35
=65%
hence the acres of land that are to be developed will be:
35/65*500
=269.23 acres
the answer is 269.23
