<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

To find 80% of 20

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

Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Coordinate Planes

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

*Note:

Rate of change is slope.

Step 1: Define

Identify.

Point (-1, -1)

Point (1, -1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

Substitute in points [Slope Formula]: $\displaystyle m = \frac{-1 + 1}{1 + 1}$
[Order of Operations] Simplify: $\displaystyle m = \frac{0}{2}$
Simplify: $\displaystyle m = 0$

Find the missing side lengths (Use sqrt in place of a square root symbol)

Kitty [74]

Step-by-step explanation:

Because this is a right triangle and it is given that one angle is 45 than also the ather angle is 45 so this triangle has 2 equal sides.So also the ather side is 6 .

Hypotenuse can be found by pythagorean theorem

6^2+6^2=x^2

36+36=x^2

x=√72

Lilit [14]

Answer:

Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds

Step-by-step explanation:

Given that a very large number of college men were asked what they thought their ideal weight was.

A five number summary of the response (in pounds) follows:

Median 175

Quartiles 155 196

Extremes 123 225

This implies that 25th percentile is 155 and 75th percentile is 196

This can be interpreted as approximately 50% of men lie between 155 and 196 pounds.

Since 195 is very near to 195, we can say approximately

i.e. 41 difference = 50%

40 difference = $\frac{40*50}{41} \\=48.78$

Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
