Answer:

BD = 26

The measure of angle ADB = 59 degrees

The measure of angle DEC = 118 degrees

Step-by-step explanation:

BD = 2 * EC = 2 * 13 = 26

The measure of angle ADB = 90 - 31 = 59 degrees

The measure of angle DEC = 180 - 2(31) = 180-62 = 118 degrees

Order from least to greatest: 2/3, 25%, 3/5, 0.40 and show work

enyata [817]

First, you will have to convert all of these numbers to decimals.
2/3=0.6 repeating
25%=0.25
3/5=0.6
0.40 is already in the decimal form
Then, you order them.
25%, 0.40, 3/5, 2/3 (because the 6 is repeating. So basically 0.60 is smaller than 0.66 in case you are wondering)

Solve for y. ln(y-1)-ln2=x+ln x

alexandr402 [8]

$ln(y - 1) - ln(2) = x + ln(x)$
$e^{ln(y - 1) - ln(2)} = e^{x + ln(x)}$
$\frac{e^{ln(y - 1)}}{e^{ln(2)}} = e^{x} * e^{ln(x)}$
$\frac{y - 1}{2} = e^{x} * x$
$\frac{1}{2}y - \frac{1}{2} = xe^{x}$
$2(\frac{1}{2}y - \frac{1}{2}) = 2xe^{x}$
$y - 1 = 2xe^{x}$
$y = 2xe^{x} + 1$

For several hours you watch a group playing dice on the street and you notice that the owner of the dice often wins.

Nostrana [21]

Answer:

there is no question

Step-by-step explanation:

It looks like the owner plays dirty, meaning he uses a trick of some kind to somehow influence the outcome in such a way, that it's outcome is no longer random.

By influencing the outcome, the owner can obtain an advantage over the playeers who are not aware of the trick or skill involved.

This is unfair and can be considered "dirty". This game is 'fixed'.

Simplify. 1/3(1−1/4)^2 Enter your answer, as a simplified fraction, in the box.

Slav-nsk [51]

Remember that $(\frac{a}{b})^c=\frac{a^c}{b^c}$

simplify inside parentahsees first

1-1/4=3/4

1/3(3/4)^2=
$(\frac{1}{3})(\frac{3}{4})^2=$
$(\frac{1}{3})(\frac{3^2}{4^2})=$
$(\frac{1}{3})(\frac{9}{16})=$
$\frac{9}{48}=$
$\frac{3}{16}=$
