Zielflug [23.3K]

Chrystelle bought 2/3 pound of ham. (given)
She bought 3/5 * 2/3 = 2/5 pound of cheese.

The cheese cost 4.95 per pound, so she paid 2/5*4.95 = 1.98 for the cheese.
The ham cost 5/3 * 4.95 = 8.25 per pound, so she paid 2/3*8.25 = 5.50 for the ham.

Her total purchase was 1.98 +5.50 = 7.48 for the ham and cheese.

Selections B, C, E are correct.

Please help don’t get it

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

$C=2\pi r$

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

$C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4$

So, it turned 785.4 feet with 1 rotation.

The correct answer is A
