I need help to this problem very difficult

Answers

Answer 1

Answer:

1. j || k and angle 1 = angle 3. 1. Given

(Those are the givens, no surprise there.)

2. angle 1 = angle 2. 2. If the lines are ||, then corresponding angles are congruent

j and k are parallel, l transverse so 1 and 2 are congruent corresponding angles.

3. angle 2 = angle 3 3. Substitution

We substitute angle 2 in for angle 1 in the other equation. This might also be called the transitivity of equality.

4. l || m 4. If alternate interior angles ...

We have congruent alternate interior angles of a transversal, so parallel lines.

Convert 12.5 miles to inches

Answers

A mile has 63,360 inches in it.
So there would be 792,000 inches in 12 miles.

1 mile = 5280 ft

1 ft = 12 inches

so 5280 ft times 12 inches = 63,360 inches in one mile

now times 63,360 inches by 12.5 miles = 792,000 inches

There were 75 rocks is Boxes A,B, and C. After moving 28 rocks fro Box A to B, 24 rocks from B to C, and 19 rocks from C to A,there was an equal number of rocks in each box. How many rocks were in Box A in the beginning?

Answers

I actually did this kind of question earlier today in a math contest. It took me a while to get it, but it was quite easy.

So we basically know that:

$A+B+C=75$

Now here comes the tricky part. We have to determine how many rocks there are in each box.

The easy thing about this is that we already know what will be in the boxes after the movements. It's just $75÷3$ .

So now we know, that after the movements, each of the boxes will contain 12.

Lets do the operations on the boxes.

$A-28+19=25$
$B-24+28=25$
$C-19+24=25$

And we find that:

$A=34$
$B=21$
$C=20$

And from that, we get:

$A=34$

Hope that helped! Enjoy.
