A man buys a car for rs.80000 and spends rs.20000 more for repairing. He sells it at rs.125000. Find his gain percent. ​
zubka84 [21]

Answer:

25%

Step-by-step explanation:

Given:

The man buys the car for 80000 units.

For repairing the car, the man spends 20000 units.

The man sells the car for 125000 units.

To find:

The gain percent of the man.

Solution:

The man buys the car for 80000 units.

For repairing the car, the man spends 20000 units.

∴ Total expenditure of the man for the car_

(80000 + 20000) units.

= 100000 units.

The man sells the car for 125000 units.

∴ Gain = (125000 - 100000) units

= 25000 units.

∴ Gain % = (25000×100)/100000

= (25000/1000)

= 25 %.

∴ The gain of the man is 25 %.

Answer:

His gain is 25%.

Compute F(s), the Laplace transform of f(t) = e^(5t) (t^2 +4t +7)
MakcuM [25]

Recall that

\mathcal L_s\{t^ne^{ct}\}=\dfrac{n!}{(s-c)^{n+1}}

Then

F(s)=\dfrac2{(s-5)^3}+\dfrac4{(s-5)^2}+\dfrac7{s-5}

A shortage of gold causes the price of gold wire to increase by 140%. If 10 feet of gold wire previously cost $50, what is the n
Marianna [84]
The increase in price is 140% of the original price.
The original price was 100% of the original price since 100% is a whole quantity.
Now the new price is 140% more than it was, so the new price is
100% + 140% of the old price.
100% + 140% = 240%

Now we find 240% of $50.
To find a percent of a number, multiply the percent by the number.

240% of $50 =
= 240% * $50
= 2.4 * $50
= $120

Answer: 10 ft of gold wire now costs $120
Gold wire now costs $12 per foot.

A room has a rectangular floor that is 15 feet by 21 feet. What is the area of the floor in square yards ? ​
Soloha48 [4]

Answer:

Hey There!

Let's solve...

Here it is a rectangular floor with length =21 cm and width =15cm

So

area = l \times w \\  = 21 \times 15 \\  = 315 {ft}^{2} \\  \\

So now We need to convert it to yards square

315ft^{2} \times  \frac{ {1yd}^{2} }{ {9ft}^{2} } \\  \\  =  \cancel{315ft^{2}}  \: ^{35}  \times  \frac{ {1yd}^{2} }{ \cancel{9 {ft}^{2} }}  \\  \\  = 35 {yd}^{2}

So how this 9 ft^2 came??

Let's know

ft \to \: yards \\  \\ 3ft = 1yd \\  \\  {3ft}^{2} =  {1yd}^{2}  \\  \\  \boxed{ {9ft}^{2} =  {1yd}^{2}}
