Given:

Selling price of radio for Masada = 63,000

Loss = 10%

To find:

The amount of money Masada paid for the radio?

Solution:

Let x be the amount of money Masada paid for the radio.

According to the question,

x-10\%\text{ of }x=63000

x-\dfrac{10}{100}x=63000

x-0.1x=63000

0.9x=63000

Divide both sides by 0.9.

x=\dfrac{63000}{0.9}

x=70000

Therefore, Masada paid 70,000 for the radio.

Noah has $5.
Nat2105 [25]

Answer:

a. $4

b. Noah has 5/5. Elena has 4/5.

Step-by-step explanation:

Noah has $5.

a.

Elena has 80% of Noah's money.

80% of $5 = 0.80 * $5 = $4

b.

Noah has $5. We can consider $5 to be the full amount.

A full amount is 100% or 1 or 5/5.

Elena has 80% of Noah's money, so she has 80/100 of Noah's money.

80/100 reduces to 4/5.

Noah has 5/5, and Elena has 4/5.

G(x)= √x+3 help plsss
const2013 [10]

Answer:

All real values of x such that x ≥-3

Step-by-step explanation:

g(x) = sqrt(x+3)

A sqrt must be greater than or equal to zero

sqrt (x+3) ≥ 0

Square each side

x+3≥ 0

Subtract 3 from each side

x ≥-3

The restrictions on x are x ≥-3

That means the domain is x ≥-3

All real values of x such that x ≥-3

Mr kapoor withdrew 25000 from an atm if he received 150 notes in denomination of 500 and 100 find the number of notes for each d
IgorLugansk [536]

We need to formulate the equation of this problem.

Let x = the number of notes for denomination of 500

      y = the number of notes for denomination of 100

We need to formulate the system of equation,

X + y = 150

500x + 100y = 25,000

Solution:

X = 150 – y

Substitute the value of x to the other equation:

500 (150 – y) + 100y = 25,000

75,000 – 500y + 100y = 25,000

-400y = 25,000 – 75,000

-400y = -50,000

y = 125

x = 150 – 125 (substitute the value of y)

x = 25

Therefore, there are 25 notes for denomination of 500 and 125 notes for denomination of 100.
