Find the least common multiple (LCM) of 4 and 5.

Answers

9514 1404 393

Answer:

Step-by-step explanation:

4 and 5 have no common factors*, so their least common multiple is their product:

4 × 5 = 20

The LCM of 4 and 5 is 20.

_____

* We're concerned with integer factors greater than 1. Of course, 1 is a factor of everything, We could say this as "no common prime factors". For computing the LCM, we really want the GCF (greatest common factor) for use in the formula ...

LCM(m, n) = mn/GCF(m, n)

A Porsche uses 2.5 litres of fuel every 2 kilometres it travels. How much fuel does it use if it travels 50 kilometres

Answers

2.5/2 = 1.25 litres per kilo
1.25 * 50 = 62.5 litres

Solution: 62.5 litres of fuel

Answer:

The Porsche uses 62.5 liters in 50 kilometers

Step-by-step explanation:

Amount of fuel Porsche uses = 2.5/2 liters/kilometer

= 1.25 L/Km

Distance to be travelled = 50 kilometer

Amount of fuel used in 50 km = 1.25 * 50

= 62.5 Liters

Therefore the Porsche uses 62.5 liters in 50 kilometers

Consider the line 2x+8y=8.

What is the slope of a line
parallel to this line?

What is the slope of a line perpendicular to this line?

Answers

Answer: parallel = - 1/4

Step-by-step explanation: perpendicular= 4

Answer:

Parallel = -1/4 ; Perpendicular = 4

Step-by-step explanation:

First, I'll put the line into slope-intercept form.

2x + 8y = 8

8y = -2x + 8

y = -1/4x + 1

Now we know that the slope is -1/4.

A parallel line would have the same slope of -1/4.

A perpendicular line would have a slope of 4.

LCM of 189024
please give me answer my question

Answers

Answer:

360

Step-by-step explanation:

We need to find the LCM of 18,90 and 24.

The prime factorization of 18 = 2 × 3 × 3

The prime factorization of 90 = 2 × 5×3×3

The prime factorization of 24 = 2 × 3×2×2

LCM is least common multiple.

LCM = 2 x 2 x 2 x 3 x 3 x 5

= 360

Hence, the LCM of 18,90 and 24 is 360.
