Answer:
If you have a calculator with a "Y^X" function, you can raise 27 to the (1/3) power to get the cube root. Or, take the logarithm of 27, divide it by 3, and then find the anti log. That is, find the base 10 log of 27, divide it by three, and then compute 10 ^ that number. (Or of course you can use the base e log and raise e to the number.)
If you are willing to get into complex numbers, you can find that there are actually three cube roots of 27. One of them is 3. To find the other two, use de Moivre's formula (from Wikipedia):
If z is a complex number, written in polar form as
then the n nth roots of z are given by
where k varies over the integer values from 0 to n − 1.
This formula is also sometimes known as de Moivre's formula.
This leads to the two complex roots,
3 x ( (cos 120 degrees) + i x sin(120 degrees) ) and
3 x ( (cos 240 degrees) + i x sin(240 degrees) ).
These work out to be approximately:
3 x (-0.5 + i x 0.866) and
3 x (-0.5 - i x 0.866).

At a cookware party, 7 of the 25 items are made of glass. What percent of the cookware items are glass?
Answer:
28 %
Step-by-step explanation:
Percentage of glass cookware items = no. of glass cookware items / total no. of cook wares * 100
= 7 / 25 * 100
= 28 %

If BD = BC , BD = 5x - 26, BC = 2x+1, and AC = 43, find AB
Answer:
BD is congruent to BC. BD=BC
BD = 5x – 26, BC = 2x + 1, and AC = 43
To find out , we need to find BC first . For that we have to find out x
WE know that BD=BC, using that we solve for x
Now we plug in 9 for x and find out BC
BC=2x+1
BC=2(9)+1
BC=19
We know AC= 43
AC=AB +AC
43=AB+19
subtract 19
AB = 24

One surface of a cut gemstone is rectangular in shape. It is 0.0002 m wide and has an area of 0.000006 m2. How long is the surface? Do your work in scientific notation.
pls help me find the answer ik in scientific notation it is 12×10^-2 but is that right??
The length of the surface in scientific form is
[tex]3 \times {10}^{ - 2}[/tex]
Given that :
Width = 0.0002 m
Width = 0.0002 mArea = 0.000006 m²
Length = l
Recall :
Area of rectangle = Length × width
Length = width / Area of rectangle
Length = 0.000006 / 0.0002
Length = 0.03 m
In scientific form ; 0.03 = 3 × 0.01 = 3 × 10^-2
=

[tex]2\frac{5}{8} *-2\frac{3}{5} \\[/tex]
rewrite the mix numbers into a improper fractions
[tex]2\frac{5}{8} = \frac{(2*8)+5}{8} = \frac{16+5}{8} = \frac{21}{8}[/tex]
[tex]-2\frac{3}{5} = -\frac{(2*5)+3}{5} = -\frac{10+3}{5} = \frac{-13}{5}[/tex]
multiply the improper fractions after rule (a/b) *(c/d) = (a*b)/(c*d)
[tex]\frac{21}{8} *\frac{-13}{5} = \frac{21*-13}{8*5} =\frac{-273}{40}[/tex]
rewrite this improper fraction as a mix number
[tex]-\frac{273}{40} = \frac{(6*40)+33}{40} = -6\frac{33}{40}[/tex]
