Americans who are 65 years of age or older make up 12.9% of the total population. If there at 30.3 million american in this age
telo118 [61]

Total population of US is 234.88 million.

Step-by-step explanation:

Given,

Number of people are 65 or older = 30.3 million

This represents 12.9% of total population.

Let,

x represent the total population.

12.9% of x = 30.3 million

\frac{12.9}{100}x=30.3\ million\\0.129x=30.3\ million

Dividing both sides by 0.129x

\frac{0.129x}{0.129}=\frac{30.3}{0.129}\ million\\\\x=234.88\ million

Total population of US is 234.88 million.

What is the prime factorization of 200?<br><br> 2 2 × 5 3<br> 2 3 × 5 2<br> 2 4 × 5<br> 2 × 5 4
Misha Larkins [42]

Answer:

2^3 * 5^2

Step-by-step explanation:

We need to break 200 down into prime numbers

200 = 20*10  These are not prime

       = 4*5  * 2*5    The 4 is not prime

       = 2*2*5  * 2*5  This is prime

Rearranging

       = 2*2*2*5*5

       = 2^3 * 5^2

Given log4(3) =0.7925 and log4(5) =1.1610, use log properties to find log4(300).
Ede4ka [16]

Answer:

4.1145

Step-by-step explanation:

You can use the following formula to solve this kind of problems,

log_{a}(b)  +  log_{a}(c)  =  log_{a}(bc)

So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.

log_{4}(300)  =  log_{4}(4 \times 5 \times 3 \times 5)  \\  =  log_{4}(4)  + log_{4}(5)  + log_{4}(3)  + log_{4}(5)  \\   = 1 + 1.1610 + 0.7925 + 1.1610 \\  = 4.1145
