What is percent decrease from 41 to 39?

SpyIntel [72]

First find the difference between 41 and 39, 41-39=2 Then divide your answer by 41 and multiply by a 100.
2/41*100=4.878%(rounded to the nearest thousandth)
So the percent decrease from 41 to 39 is 4.878%

Which expression is equivalent to? Assume x > 0 and y > 0.

shtirl [24]

Answer:

The correct answer is third option

√5/(x²y)

Step-by-step explanation:

It is given an expression,√(55x⁷y⁶/11x¹¹y⁸)

Points to remember

Identities

xᵃ/xᵇ = x⁽ᵃ ⁻ ᵇ)

x⁻ⁿ = x¹/ⁿ

To find the equivalent expression

We have, √(55x⁷y⁶/11x¹¹y⁸)

By using above identity we can write,

√(55x⁷y⁶/11x¹¹y⁸) = √[(55/11) (x⁷/x¹¹) (y⁶/y⁸)]

= √[5x⁷⁻¹¹ y⁶⁻⁸]

= √[5x⁻⁴ y⁻²]

= √[5/x⁴y²]

= √5/(x²y)

Therefore the correct answer is third option

√5/(x²y)

The distance between two points is the number of units between them.

Halfway points (a) and (b)

To locate a point halfway points (a) and (b), we use the following steps

Calculate the absolute difference between both points
Divide the absolute difference by 2
Add the quotient to the smaller point.

Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be

$P = a + \frac{|a - b|}{2}$

Take for instance, a = 5, and b = 10.

The halfway point would be:

$P = 5 + \frac{|5 - 10|}{2}$

$P = 5 + \frac{5}{2}$

$P = 5 + 2.5$

$P = 7.5$

The halfway point between 5 and 10 is 7.5

The formula works for negative values, and absolute values are used to return the actual difference between both points

Real world circumstance

The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)

Fractional distance

To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.

Take for instance, three-fourths from (a) to (b) would be:

$P = a + \frac{3|a - b|}{4}$
