It would just be that 2(black area) + white area = 6 cm^2, so 3 * white area = 6 cm^2 so white = black = 2 cm^2

Hello Guest!

Variables: 

If we set line QZ as x, then line AQ would be 42 - x. 

QZ = x

AQ = 42 - x

BQ = 8

QY = 28

Similar:

The first thing to note is that triangle ABQ is similar to triangle ZYQ. 

That also means that the side length ratios are the same. 

That means BQ/AQ = QY/QZ 

Equation:

BQ/AQ = QY/QZ can be written as 8/(42 - x) = x/28.

8/(42 - x) = x/28

1176 - 28x = 8x

1176 = 36x

x = 98/3

Answer:

Since x is QZ, our answer is 98/3. 

However, I am not the most confident. 

I hope this helped.  :)))))

There are 1400 possible combinations.

The area of the triangle is 7/2.

There is a very neat formula that you can use:

(a) - 1/2 mile =5280 feet / 2=2,640 feet

Distance to horizon =Sqrt[1.5 * 2,640] =sqrt[3,960] =~63 miles

Do exactly the same thing for (b) and (c).

Nice job catmg!!

Thanks for explaining this in a different way That helped alot UwU

Remeber to give a full explation because the guest Might not understand, but Im not sure how to answer this so I cant tell if this answer is correct or not. 

And i still can help you witch promblems if you would want

So do you need help finding the answer or..?

Visible black area = 2 cm²

Dont feel bad everyone makes mistakes!

Happy new years!

the max is 44º ==> error

The right answer is   ∠BAC = 80º 

0, because if each lawyer shakes hands with each politician twice, then that would break the rules of each politician shaking hands with each person only one time.

To maximize the number, we want the numbers to be as close in value as possible. If we take any number as the sum of the two factors, say 12, we can see that 6*6 is larger than 11*1.

We know that by adding the numbers from 1-10 we get 55, so we want values of 27 and 28.

The first thing that comes to mind would be 10+9+8*7+6+5+4+3+2+1, which is 27 and 28 when multiplied, is 756.

To minimize the amount, the numbers have to as far apart as possible. 

To get this, we use the smallest numbers, 1,2, and 3 for the 3 first boxes, and the rest of the numbers in the other boxes.

1+2+3 is 6, and 55-6 is 49. 6*49 is 294.

So the largest number would be 756, and the smallest would be 294.

The solutions are x = 1, 2, and 4.

[Q + Q - 4 + Q + 1 +3Q + 24]=27

Q = 12 - Third pile

4 * 3 = 12 - Fourth pile

Triangles BDC and ACD are coplanar and isosceles. If we have angle ABC = 70, what is angle BAC, in degrees?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

The diagram shows that the angle ABC cannot be 70º; the max is 44º (as integer)

Hello Cryingcathuehue, 

Slope

To start, a line is parallel to another when both lines have the same slope so we need to find the slope of the line 2x + 3y = 21. 

We can do this by turning the equation in the form of y = mx + b, where m is the slope. 

2x + 3y = 21

3y = -2x + 21

y = (-2/3)x + 7

Thus, the slope of the line much be -2/3

Finding j

So we know the line has a slope of -2/3. Slope is also known as y/x. So for every time the y goes down by -2, the x goes up by 3. 

From -9 to 17, the y went up by 26, meaning that the x went down by 39. -2:3 = -26:39. 2 - 39 = -37. 

Answer

j = -37

I hope this helped. :)))
