The total area of Ohio is 4.5 * 10^4 square miles.The total area of Ohio is about how many times the total area of Rhode Island?

Anon25 [30]

Answer:

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

Let

x -----> the total area of Ohio in square miles

y -----> the total area of Rhode Island in square miles

we know that

$x=4.5*10^{4}\ mi^{2}$

$y=1.5*10^{3}\ mi^{2}$ (<em>searched in Google</em>)

To find out approximately how many times the total area of Ohio is compared to the area of Rhode Island, divide the area of Ohio by the area of Rhode Island

$\frac{x}{y}$

substitute the values

$\frac{4.5*10^{4}}{1.5*10^{3}}=(\frac{4.5}{1.5})( 10^{4-3}) =3*10^{1}=30$

therefore

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

If there must be at least 4 people in each group, then the number of people in the group for tennis must be 4, 5, or 6.

There are

(10/k)=(10!)/(k!(10−k)!)

ways of choosing k people from a group of 10, and so there are

(10/4)+(10/5)+(10/6)=(10!)/(4!6!)+(10!)/(5!5!)+(10!)/(6!4!)

=2×(10×9×8×7)/(4×3×2×1)+(10×9×8×7×6)/(5×4×3×2×1)

=2×(10×3×1×7)/(1×1×1×1)+(1×3×2×7×6)/(1×1×1×1×1) =420+252=672
