Find a number that has exactly 7 different prime factors. Explain how you found it.

1 answer:

5 0

The first seven prime numbers are 2, 3, 5, 7, 11, 13, 17
If you multiply all those numbers together, you'll have a product with 7 different prime factors (each of the numbers you multiplied).
So, 2 x 3 x 5 x 7 x 11 x 13 x 17 = 510,510

Answer:

Step-by-step explanation:

Area = 1/2( base times height)

since the height is perpendicular to the base

therefore

6 = 1/2(3) h

12 =3h

-2x+15y=-24<br> 2x+9y=24 <br> solve the system of equation

zhuklara [117]

Answer:

x = 12, y = 0

Step-by-step explanation:

Use elimination.

24y = 0

y = 0

Then plug back into the second equation.

2x + 9(0) = 24

2x = 24

x = 12

Plug back into the first equation to check.

the diameter of a pearl is about 4×10-¹⁴ cm and the diameter of an atom is about 10-¹¹ m. how much larger than an atom is a pear

serious [3.7K]

Answer:

The diameter of an atom is 25000 times the diameter of a pearl.

Step-by-step explanation:

Given that,

The diameter of a pearl is $4\times 10^{-14}\ cm$

The diameter of an atom is $10^{-11}\ m=10^{-9}\ m$

Taking the ratio,

$\dfrac{\text{diameter of an atom}}{\text{diameter of a pearl}}=\dfrac{10^{-9}\ m}{4\times 10^{-14}\ m}\\\\=25000$

So, the diameter of an atom is 25000 times the diameter of a pearl.
