The diameter of a ping pong ball is 4.0cm. find the length in kilometers of a row of 6.02×1023 ping pong balls.

Vikentia [17]

The length is determined by multiplying the number of balls with the diameter. The answer that would come out of this is in units of centimeters.

L = (6.02 x 10^23 balls)(4 cm/ball)
L = 2.408 x 10^24 cm

Then, we use the proper conversion factor to convert centimeter to kilometer.

L = (2.408 x 10^24 cm)(1 m/100 cm)(1 km/1000 m)
L = (2.408 x 10^24)(10^5)

The answer to this item is 2.408 x 10^19 km.

-6h plus 4 - 3plus h equals 11

olga55 [171]

$- 6h + 4 - 3 + h = 11$
So we start by combining like terms;
$- 6h + h = - 5h$
$4 - 3 = 1$
Now we have;
$- 5h + 1 = 11$
We then subtract 1 from both sides;
$- 5h + 1 = 11$
$- 5h = 10$
Then we divide both sides by 5;
$- 5h = 10$
$- 5h \div - 5h = h$
$10 \div - 5h = - 2$
Leaving the final answer to be h = -2
