Answer:

\huge\boxed{\text{B) 1}}

Step-by-step explanation:

In order to find which expression is equivalent to (8^5 \times 3^{-7})^0, we need to note the order of operations.

PEMDAS tells us that when solving an equation, we'd go in this order.

<em>P</em><em>arentheses</em>

<em>E</em><em>xponents</em>

<em>M</em><em>ultiplication/</em><em>D</em><em>ivision</em>

<em>A</em><em>ddition/</em><em>S</em><em>ubtraction</em>

Using this, we'd start by evaluating what's inside the parentheses, 8^5 \times 3^{-7}. We'd then bring that value to the 0th power.

<em>Wait...</em> there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.

It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.

So no matter what the value inside the parentheses is, taking it to the 0th power will <u>always make it 1</u>.

Therefore, this expression is equivalent to 1.

Hope this helped!

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 1 or a 9 is 2/9 . What is the probability
shtirl [24]
The probability of NOT getting a 1 or a 9 means you have to subtract those two numbers and how many of each are out. Once you do that, count the remaining numbers, put them as the numerator, and then put the overall total of numbers as the denominator. Your answer is 7/9.

Consider the following rational numbers -5.1 -5 1/3 -5 -5 3/5 list them in order from least to greatest
jok3333 [9.3K]

Answer:

-5.6, -5.3, -5.1, -5.

Step-by-step explanation:

Convert the first fraction to a decimal.

-5 1/3 is equal to -5.3333333333

Round to the nearest tenth.

-5.3333333333 rounded to the nearest tenth is -5.3.

<em>-5 1/3 = -5.3.</em>

<em />

Convert the second fraction to a decimal.

-5 3/5 is equal to -5.6.

The fraction is already rounded, so that's all for the second one.

<em>-5 3/5 = -5.6.</em>

<em />

The new set of numbers we have include -5.1, -5.3, -5, and -5.6.

We can now sort from least to greatest.

The first number is -5.6.

The second number is -5.3.

The third number is -5.1.

The fourth number is -5.

Listing the numbers -5.1, -5.3, -5, and -5.6 from least to greatest would result in -5.6, -5.3, -5.1, and finally -5.
