Divide 2 by 5 to get a decimal, then multiply the decimal by 100 to get a percent.

2/5 = 0.4

0.4x100 = 40

2/5 = 40%

mash [69]

The total amount of money which komal spent during her vacation is

$65.67

Given, Komal bought 3 shirts for $11.21 each.

She also spent her money on a keychain for $2.40 and a mug for $6.47.

After that she spent $23.17 for getting her picture developed.

How much in total she spend her money = ?

Money spent on shirts:

Cost for one shirt =  $11.21

cost for three shirts = 3 × 11.21

= $33.63

Now add the amount of all the items Komal bought for herself.

Total money spent = cost price of shirts + cost price for a keychain + cost price for a mug + cost price for getting a picture developed.

Total money spent = 33.63 + 2.40 + 6.47 + 23.17

Total money spent = $65.67

Hence the total money Komal spent is $65.67.

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.
