Simplify the expression (0.4)³

Mathematics

Kamila [148]3 years ago

First of all, 0.4 is also 4/10 because it has one number after the decimal point.
So that will be
(4/10)³
Which is the same as
4³/10³
4 x 4 x 4/ 10 x 10 x 10
64/1000
When divided, it will be
0.064
Or
32/500
16/250
8/125
Hope I helped. Have a nice day

Part a - obtaining conversion factors from unit equality relationships in an experiment you are performing, your lab partner has
DanielleElmas [232]

Solution:

As we given that 1 inch=2.54 cm

then using this conversion factor we can write  28.4 inch=28.4* (1 inch)

and further it can be written as

28.4* (1 inch)*(2.54 cm/1 inch)=28.4*2.54 cm= 72.136 cm

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.

Solve each system of equations algebraically y= x-6 y= 2x
lbvjy [14]

Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)
