DUS is a 30°-60°-90° triangle with short leg SU. If SU = x, determine the
vitfil [10]

Answer:

SD = 2x

UD = x\sqrt{3}

Step-by-step explanation:

The hypotenuse of a 30-60-90 triangle is 2 times the length of the shorter leg.

SU is the shorter leg = x

So, SD = 2x

The longer leg of a 30-60-90 triangle is \sqrt{3} times the shorter leg.

So, UD = x\sqrt{3}

Which system of linear inequalities is graphed?
ANEK [815]

To determine the system of inequality that has been graphed, we need to be very smart.


Observe that all the equations are the same.


Also note that all the lines are solid. This should tell you that the inequities should involve.


\ge \:or\: \le



Therefore the answer is between option A and B.



So we choose a point in the solution region to discriminate between A and B.


Let us choose the origin since that is easy to evaluate.


We substitute into option A to get.

y\le 3x-1\:and\: x+ 3y \ge 6




0\le 3(0)-1\:and\: 0+ 3(0) \ge 6




0\le -1\:and\: 0\ge 6


The above statements are false



We now substitute into option B



y\ge 3x-1\:and\: x+ 3y \le 6




0\ge 3(0)-1\:and\: 0+ 3(0) \le 6




0\ge-1\:and\: 0 \le 6


Both statements are true, therefore the correct answer is option B.

Write and equation ( and maybe solve) please!
mihalych1998 [28]
49.75 - 8 = 41.75.  41.75 / 1.369 = 30.4967129.  Let's round it to 2 decimal points, which is 30.5.  The maximum number of litres of gasoline that Terri can purchase is 30.5.  If m= money, c= price of car wash and g= price of gasoline per litre, the equation is (m - c) / g.
