Answer:

21:27 and 14:18

Step-by-step explanation:

We can solve this by using common factors

one of the common factors of 54 and 42 is 3

42/3=14

54/3=18

so one of the ratios is 14:18

another common factor is 2

42/2=21

54/2=27

so another ratio is 21:27

Answer:

8.28%

Step-by-step explanation:

According to the U.S. Census Bureau, the legal official department in charge of the National Census every ten years, the population of the U.S.A in 2010 was<em> 308,745,538 inhabitants.</em>

If about 25,585,000 had diabetes, then <em>cross multiplying</em>

308,745,538-------100%

25,585,000---------x%

and

\frac{308,745,538}{25,585,000}=\frac{100}{x}

and so, about

x=\frac{25,585,000*100}{308,745,538}=8.28 \%

Americans had diabetes in 2010.

. How are the formulas for the circumference of a circle and area of a circle derived?
kakasveta [241]
They can be derived by using calculus(integration to be precise)

\pi= \frac{circumference }{diameter}(its how pi is defined)
so that gives circumference

to get area , you use integration of an elemental ring of radius r and thickness dr and integrate itA= \int\limits^0_r {2 \pi r} \, dr

that gives the area.

if you don't know calculus yet ,dont worry, just remember the formulae.
