37% of what number is 99.9?

siniylev [52]

Answer:

270

Step-by-step explanation:

37 % of a number is the same as divide by 100 and multiply by 37. To get this number we do the opposite: divide 99.9 by 37 which gives us 27 and then multiply by 100 which will give us 270.

if we check this: 270 /100 *37 = 99,9

Write (1/3i)-(-6+2/3i) as a complex number in standard form

Eddi Din [679]

Answer:

$6+\frac{i}{3}$

Step-by-step explanation:

$\frac{1}{3\imath}-(-6+\frac{2}{3\imath})$

$\frac{1}{3\imath}+6-\frac{2}{3\imath}$

taking like terms together

$\frac{1}{3\imath}-\frac{2}{3\imath}+6$

taking LCM

$\frac{1-2}{3\imath}+6$

$\frac{-1}{3\imath}+6$

taking LCM

$\frac{-1+18\imath}{3\imath}$

splitting the term

$\frac{-1+18\imath}{3\imath}$

splitting the term

$-\frac{1}{3\imath}+\frac{18\imath}{3\imath}$

$-\frac{1\times3\imath}{3\imath \times \imath}+6$

$-\frac{i}{3\imath^2}+6$

we know that

$\imath^2=-1$

putting this value in above equation

$\frac{\imath}{3}+6$

These two regular pentagons are similar. The length of each side on pentagon A is 4 cm. The length of each side on pentagon B is

Monica [59]

We know that
pentagon A is the smaller pentagon----> length side 4 cm
and
pentagon B is the larger pentagon-----> length side 6 cm
so
the scale factor from pentagon B to pentagon A=length side B/length side A
6/4----> 3/2---> 1.5

the answer is the option
B) 1.5
