2. In the diagram below, set I represents rational numbers, set II represents integers, and set III represents whole numbers. Sh
MrRa [10]

The information about the rational numbers and integers shows that the correct option is C.

<h3>How to explain the information?</h3>

It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Therefore, the correct option is C.

John left the museum and drove south at a rate of 55 mph. Sally left four hours later driving 10 mph faster than John in an effo
Leona [35]

Answer:

22 hours (B)

Step-by-step explanation:

John's velocity = 55mph

Sally's velocity = 65mph

John's time taken = x

Sally's time taken = x - 4

since they must cover the same distance.

and, distance = vel × time

Sally's vel × time = John's vel × time

55x = 65(x-4)

55x = 65x - 220

-10x = -220

x = 22 hours.

Therefore, Sally catches up after 22 hours

Which expression is equivalent to
deff fn [24]

Answer:

b) log8 4 + log8 a + log8 (b- 4) - 4 log8 c

Step-by-step explanation:

The given expression is log8 4a ((b - 4) ÷ c^4)

Here we have to use the quotient rule.

log(a/b) = log a - log b

log8 4a (b- 4) - log8 4a(c^4)

Using the product rule log(ab) = log (a) + log (b)

log8 4a + log8 4a(b-4) - log8 4a - log8 (c^4)

log8 4a(b - 4) - log8 (c^4)

log8 4a + log8 (b- 4) - 4 log8 c

Again using the product rule.

log8 4 + log8 a + log8 (b- 4) - 4 log8 c

So it is b.

Thank you.
