As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.
16 miles = x miles
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
Answer:
A. 56.52 cm
Step-by-step explanation:
Formula:
Circumfrence= 2πr
r (radius) = 9 cm
C = 2πr
C = 2 x 3.14 x 9 cm
C = 6.28 x 9 cm
C = 56.52 cm
Circumfrence is 56.52 cm
The answer for the exercise shown above is the option B, which is:
<span> B. log5(7)+5log5(a)
The explanation of the problem is shown below:
1. You have the following expression given in the problem above:
</span><span>log5(7)(a^5)
2. To expand it, you must use the logaritms properties, as following:
</span> log5(7)(a^5)
log5(7)+log5(a^5)
log5(7)+5log5(a)
3. Therefore, as you can see, the answer is the option B.

The easiest way to solve this is to convert all of the values to a decimal value, and then order the numbers as you normally would.
1/5=0.2
-4.06
10/5=2
-4.30
Now that we know the decimal values, we can simply place them from least to greatest. -4.30, -4.06, 1/5, 10/5 is the correct order.
