Answer:

55.82 cm

Step-by-step explanation:

d1= 8.72 cm

a= 15.6 cm

A rhombus= 1/2*d1*d2 = A square

A square= 15.6²= 243.36 cm²

d2= 2A/d1= 2*243.36/8.72 ≈55.82 cm

2x + y = 2<br><br> x – 2y = -4<br><br> what is x and y?
sergiy2304 [10]

Answer:

x = 0

y = 2

Step-by-step explanation:

2x + y = 2 (Multiply by 2)

x – 2y = -4

4x + 2y = 4

x – 2y = -4

5x = 0

x = 0

2x + y = 2

2(0) + y = 2

0 + y = 2

y = 2

Which method is valid for proving that two circles are similar?
Masteriza [31]
First I'm going to go through the choices with you and evaluate
each one.  Then after that, I'm going to hand you a secret that
I promise is going to knock your socks off.


a- Calculate the ratio of the diameter to the radius for each circle
and show that they are equal.
-- That won't tell you anything. The ratio of the diameter
to the radius of EVERY circle is 2 .

b- Calculate the ratio of degrees to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The circumference
of EVERY circle subtends a central angle of 360°.

c- Calculate the ratio of the área to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The ratio of the area
to the circumference of EVERY circle is (radius/2). 
They're only equal if the circles are the same size.

d- Calculate the ratio of the diameter to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything.  The ratio of the diameter
to the circumference of EVERY circle is  1/pi.   If the ratio isn't
1/pi, then you're not looking at a circle. 

None of these choices tells you whether the two circles are similar.
What are you going to do ?  How can you tell ? ?

Here's the surprise I promised you.
Beware of flying socks:

All circles are similar to all other circles.

Good night.
