Caroles new job will pay $3,525 per month, but about 30% will be withheld for taxes. Estimate her pay after taxes
Juli2301 [7.4K]

Answer:

i think the answer would be $2467.5 per month (got exact answer without estimating)

Step-by-step explanation:

30% (taxes) in decimals would be 0.3

so .3 mutiplyed by 3,525 would equals 1057.5

which then you would subtract 3,525-1057.5 =

$2467.5

The Milky Way has a radius of approximately 50,000 light years. The visible universe has a size of approximately 15 billion ligh
salantis [7]

Answer:

24 kilometers

Step-by-step explanation:

It's a simple calculation using cross multiplication:

We have the following ratios:

\frac{8}{x} = \frac{50,000}{15,000,000,000} \\\\x * 50,000 = 8 * 15,000,000,000\\\\x = 2,400,000

That's 2.4 million of cm... or 24 000 meters... or 24 kilometers.

That's equivalent to 300,000 cups placed side by side.  That's a long way!
