Answer:

2000 cm^2/min

Step-by-step explanation:

According to the given question,

12 m^2/h = ? cm^2/min

We know,

1 h = 60 min and 1 m = 100 cm

So, by putting the values we get

12 m^2/h = 12 × (100)^2/60

12 m^2/h = 12×10000/60

12 m^2/h = 2000 cm^2/min

Thus the answer of the given question is 2000 cm^2/min .

Gre4nikov [31]

Answer:

$120\ minutes$

Step-by-step explanation:

step 1

Alex’s printer

we know that

print 8 photos in 12 minutes

by proportion

Find how long will it take the printer to print 120 photos

$\frac{12}{8}=\frac{x}{120}\\ \\x=120*12/8\\ \\x=180\ minutes$

step 2

Khalil’s printer

we know that

print 24 photos in 1 hour (60 minutes)

by proportion

Find how long will it take the printer to print 120 photos

$\frac{60}{24}=\frac{x}{120}\\ \\x=120*60/24\\ \\x=300\ minutes$

step 3

Find the difference

$300\ minutes-180\ minutes=120\ minutes$

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use PT to solve for the missing side length.

Step 2: Identify Variables

Leg a = 72

Leg b = 65

Hypotenuse c = x

Step 3: Solve for x

Substitute [PT]: 72² + 65² = x²
Exponents: 5184 + 4225 = x²
Add: 9409 = x²
Isolate x: 97 = x
Rewrite: x = 97
