Answer:

  9

Step-by-step explanation:

Let x represent the number of ₹50 notes. Then the number of ₹10 notes is (x+1) and the total value of all notes is ...

  ₹50·x + ₹10·(x+1) = ₹550

  ₹60·x = ₹540 . . . . . . . . . . . . subtract ₹10 and collect terms

  x = 9 . . . . . . . . . . . . . . divide by ₹60

The number of ₹50 notes is 9.

Answer:

The number of ₹ 50 notes is 9.

Step-by-step explanation:

Solution :

Let,

  • No. of notes of ₹10 = x

The number of rupees 50 notes is one less than of ₹10 notes

So,

  • No. of notes of ₹50 = x - 1

★ <u>According to the Question</u> :

⇒ x (10) + (x - 1) 50 = 550

⇒ 10x + 50x - 50 = 550

⇒ 60x = 550 + 50

⇒ 60x = 600

⇒ x = 600/60

⇒ x = 10

No. of notes of ₹10 = 10

• <u>No. of notes of ₹50</u> = x - 1

⇒ 10 - 1 = 9

No. of notes of ₹50 = 9

Therefore, the number of ₹ 50 notes is 9.

miskamm [114]

Answer:

volume = 195.52 in³

Step-by-step explanation:

given data

slant height of the cake = 10 inches

base length =  8 inches

solution

we know that volume pyramid is express as

volume = \frac{A^2\times h}{3}    ..............1

here

we use pythagoras for height

hypotenuse² = side1² + side2²    

put here value with other side is half of a square side

10² = h² + 4²

solve it we get

h = 9.165 in

so put here value in equation 1 we get

volume = \frac{8^2\times 9.165}{3}  

volume = 195.52 in³

Solve for X: -3 |2x+6| = -12
Kobotan [32]
Hello there!

-3| 2x + 6| = -12
2x + 6 = -12/-3
2x + 6 = 4
Solve absolute value
We know that 2x + 6 = 4 or 2x + 6 = -4
We have two possibilities to solve this.

1)
2x + 6 = 4
2x = 4 - 6
2x = -2
Divide both sides by -2
2x/-2 = -2/-2
x = 1


2) 
2x + 6 = -4
2x = -4 - 6
2x = -10
Divide both sides by 2
2x/2 = -10/2
x = -5

Answer : X = -1 or X = -5

A+ Guaranteed!

A certain animated movie earned $1.1*10^9 in revenues at the box office. The movie lasts 9.1*10^1 minutes. How much revenue was
Vadim26 [7]

Answer:

$12,087,912.1

Step-by-step explanation:

1.1*10^9  is in scientific notation, to get this into normal number, we take the decimal point and move it "9" times to the right [whatever power of 10 we have, we move to right (if positive).] Then we fillup the rest with zeros.

So we have:

1.1*10^9=1,100,000,000

This is the revenue.

We do similar process for time:

9.1*10^1=91

This is the time , in minutes.

We want revenue PER minute, that means we divide the total revenue by total time, that would be:

\frac{1,100,000,000}{91}=12,087,912.1

The revenue earned per minute is  $12,087,912.1
