<h2>Answer:</h2>

When you say Percent, you really mean per 100. So percentage is the result you get when multiplying a quantity by a percent. To find 80% of 20, we can use the following expression:

$20\times \frac{80}{100}=16$

That is the product of 80 and 20 divided by 100, which is 16.

Answer:

The correct answer is

80% of 20 = 16

Step-by-step explanation:

points to remember

x% of y is given by

(x/100) * y

<u>To find 80% of 20</u>

Let 'x' be the 80% of 20 then we can write,

x = (80/100) * 20

x = (8/10) * 20

= 8 * 2 = 16

Therefore 80% of 20 is 16

The correct answer is 16

When Sarah divided a number by 5, the quotient was 247 with a remainder. What is one possible dividend? With a complete sentence

Stolb23 [73]

Answer:

When a number is divided by 5 and the result is 247 with a remainder, one possible dividend is 1236.

The quotient of a number is the number that is gotten when a number is divided by another number. For example, the quotient of 10 and 2 is 5.

An unknown number was divided by 5 and the result was 247 with a remainder. In order to determine the number the first step is to determine the product of 247 and 5.

247 x 5 = 1235

Since the number has a remainder, the number cannot be exactly 1235. The number would lie between 1235 and 1240. The numbers can be 1236, 1237, 1238 and 1239.

Which expression is equivalent to 4^-5 • 3^-5 ?

valkas [14]

The expression equivalent to 4^-5 • 3^-5 is 12^-5

<h3>What are equivalent expressions?</h3>

Equivalent expressions are simply known as expressions with the same solution but different arrangement.

Given the index expressions;

4^-5 • 3^-5

Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.

This can be written as;

4(3) ^ -5

expand the bracket

12^-5

Thus, the expression equivalent to 4^-5 • 3^-5 is 12^-5
