A tank can contain 40 gallons of gas, but it is not completely full. How much gas is in the tank if 6.5% of the tank is empty?

To find this, we have to multiply the total amount of gas the tank can hold (40 gallons) by how much gas is in the tank (93.5% or .935 as a decimal). When we do this we get the amount of gas 37.4 gallons.

A person died leaving property worth rs.4000.40. His widow get 0.125 of the property and his son got 0.4 of the remainder. What
belka [17]

Answer:

Widow's Share = Rs 500.05

Son's share = Rs 1400.14

Step-by-step explanation:

Property = 4000.40

Widow get share = 0.125

So, Share of Widow = 0.125 * 4000.40

Widow's Share = Rs 500.05

Remaining Property = 4000.40 - 500.05

Remaining Property = 3500.35

Son's share = 0.4 * 3500.35

Son's share = Rs 1400.14

Archy [21]

Answer:

-6x^6y^5

Step-by-step explanation:

you have to find p such that

(-3x^{3}y)(p) = 18x^{9}y^{4}

So just divide to find p

p = \frac{18x^{9}y^{4} }{-3x^{3}y} = -6x^{6}y^{5}

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.
