1 answer:
irinina [24]3 years ago
5 0

Answer:

The answer is x = - 3

Step-by-step explanation:

You multiply both sides of the equation by  4 x^3 = -27

Write or type it in exponential form with an exponent of  3 x^3 +( -3)^3

Take the root of both sides of the equation  x^3= (-3) ^3

Solution is: x = - 3

Hope this helps! :) <33

the volume of metal in a scale model of a metal high tension tower is 54 cm cubed. The scale used was 1:50. it required 50 mm of
daser333 [38]

Answer:

6,750,000 cm³ = 6.75 m³

Step-by-step explanation:

a scale version means that the ratio of every dimension of scale vs. real object is 1/50.

volume is created by multiplying 3 dimensions.

so, going from scaling to real the volume has to be multiplied by 50×50×50 = 50³ = 125000

so, as for the scale model we needed 54 cm³, for the full size object we need 54×125000 = 6,750,000 cm³ of metal.

or to bring it to m³ (1m³ = 100×100×100 cm = 1000000 cm³)

that would be 6.75 m³ of metal.

Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:
\left \{ {{x+y=32} \atop {3x+27y=408}} \right. \ =\ \textgreater \  \  \left \{ {{x=19 (cars)} \atop {y=13(buses)}} \right.
