It takes 60 minutes to make 2000 copies on an old copy machine. The newer copier works with the old copier to create 2000 sheets
Cerrena [4.2K]

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

60:2000::15:x

Product of mean = Product of extreme

2000*15=60*x\\30000=60x\\60x=30000

Dividing both sides by 60

\frac{60x}{60}=\frac{30000}{60}\\x=500

As the new copier is working with old copier, therefore,

Copies made by new printer = 2000 - 500 = 1500

New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion

1500:15::2000:x\\1500*x=15*2000\\1500x=30000

Dividing both sides by 1500;

\frac{1500x}{1500}=\frac{30000}{1500}\\x=20

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

(13 – 6)^2 (5 + 2)^2÷(5 – 2)^3

PEMDAS

Parentheses first

(7)^2 (7)^2÷(3)^3

Then exponents

49*49 ÷27

Then multiply and divide from left to right

2401÷27

2401/27

HELP NEEDED PLEASE!
lisabon 2012 [21]

Answer:

V = 166.4

Step-by-step explanation:

The ratio of lengths of similar figures is the scale factor.

The ratio of the surface areas of similar figures is the square of the scale factor.

The ratio of the volumes of similar figures is the cube of the scale factor.

We don't know the scale factor of the figures, but we know the ratio of the surface areas is 200/135.

That is the square of the scale factor.

Let k = scale factor.

k² = 200/135 = 40/27

The ratio of the volumes is

k³ = [√(k²)]³

k³ = [√(40/27)]³ = 1.80320

V = 300/1.80320

V = 166.4
