You haven't said what your question is, or even whether you HAVE
a question to ask

After everything you went through to give information, we might guess
that your question could be . . . "What combos should she try ?"

If you don't consider zero to be an even number, then there are
13 possibilities:

<span> <span><span> 1425
</span> <span> 1463 </span> <span>
1843 </span> <span>
3249 </span> <span>
3287
</span><span>3629
</span> <span> 5263
</span> <span> 5643
</span> <span> 5681
</span> <span> 7429
</span> <span> 9481
</span> <span> 9823
</span> <span> 9861 </span> </span></span>


If you DO consider zero to be an even number, then there are 11 more
possibilities, for a total of 24 all together:

<span> <span><span> 1045
</span> <span> 1083
</span> <span> 1805
</span> <span> 3021
</span> <span> 3401
</span> <span> 7049
</span> <span> 7201
</span> <span> 7809
</span> <span> 9025
</span> <span> 9063
</span> <span> 9405 </span> </span></span>.

This is one time when I'm going to ignore my own #1 Cardinal Rule for answering questions on this site.  Normally I'm totally against simply dumping an answer without explaining how I got it.  In this case, however, I never found the short, easy, clever way to answer this one.  I just slogged through all of the 473 multiples of 19 that have 4 digits, and weeded out the ones that don't fit your specifications.  I used a popular office software program to grease the process, but even so, there absolutely must be a better way to do it, and I would not wish this one on you, so I'm not going to describe it.

I'm grateful for your 5 points.  The crust and warm cloudy water are delicious.

1/56 divided by -30 write fractions is simplest form
Nady [450]

Simplified form of 1/56 divided by -30 is  =-\frac{1}{1680}

Step-by-step explanation:

We need to solve 1/56 divided by -30 in simplest form.

Solving:

Writing in mathematical form:

\frac{1}{56}\div -30

Converting division symbol into multiplication and taking reciprocal of -30

=\frac{1}{56}\times \frac{1}{-30}

Simplifying:

=\frac{1}{56*-30}

=-\frac{1}{1680}

So, simplified form of 1/56 divided by -30 is  =-\frac{1}{1680}

Which addition does the model below represent?
Nastasia [14]
<h3>Answer:</h3>

[C] 3 + ( - 4).

<h3>Explanation:</h3>
  • First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3.
  • Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero.
  • When adding a negative to a positive, you convert it to subtraction.
  • 3 + -4 is the same as 3 - 4.

<u>Correct choice</u> - [C] 3 + (- 4).

<u>Note</u>: See the picture attached.

Please help, it's for a geometry quiz, show all work please, question in the image attached
aliya0001 [1]

Answer:

m<ABC=94°

m<BCD=25°

m<ACB=43°

Step-by-step explanation:

To find <mBCD

m<ABD=133°, so m<CBD=133° too.

A triangle is equal to 180°.

22°+133°=155°

80°-155°=25°

To find <mACB

You first need to know triangle ACD measurements.

m<ADC=44° (22°+22°)

Then you take the two 25 and add them.

25°+25°=50°

50°+44°=94°

180°-94°=86°

86°÷2=43°

To find m<ABC

43°+43°=86°

180°-86°=94°
