3 yards = $7.47
1 yard = $(7.47 ÷ 3) = $2.29
2 yards = $ (2.29 × 2) = $5.58
$ (7.47 + 5.58) = $ 13.05

You divide 7.47 by 3. Which is 2.49
Then you multiply 2.49 by 2 which is 4.98
The two extra yards of fabric would cost $4.98

Write the set of points from  -6 to 0 but excluding  -4  and 0 as a union of intervals

First we take  the interval  -6 to 0. In that -4  and 0 are excluded.

So we split the interval -6 to 0.

Start with -6 and go up to -4. -4 is excluded so we break at -4. Also we use parenthesis for -4.

Interval becomes [-6,-4) . It says -6 included but -4 excluded.

Next interval starts at -4 and ends at 0. -4 and 0 are excluded so we use parenthesis not square brackets

(-4,0)

Now we take union of both intervals

[-6,-4) U (-4,0)  --- Interval from  -6 to 0 but excluding  -4  and 0

What is the approximate percent decrease when a fish count goes down from 850 to 500? The percent decrease is approximately 40%.
Korolek [52]

Answer:

<h2><em>The percent decrease is approximately 40%. </em></h2>

Step-by-step explanation:

Step one:

given data

initial count of fish= 850

final count of fish= 500

Required

% decrease

Step two:

% decrease= final-initial/initial*100

substitute

% decrease= 850-500/850*100

% decrease=350/850*100

% decrease= 0.41*100

% decrease= 40.1%

<em>The percent decrease is approximately 40%. </em>

Help? I'm pretty confuse on both of these? Please explain?
MAVERICK [17]
35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10   (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.
