Answer:

X= 9/sqrt3; Y= 18/sqrt3

Step-by-step explanation:

This is a 30, 60, 90 triangle, so the shortest side is x, the longer leg xsqrt3 and the hypotenuse is 2x.

xsqrt3=9, so divide both sides by sqrt3 to get x=9/sqrt3

Then y=2x, so multiple 9/sqrt3 by 2 to get 18/sqrt3

Δ = b^2 - 4.a.c = 4 - 4.6.3 = -68< 0

rootΔ = root(-68)

no real solutions :) Cause -68 not positive.

Good Luck :)

135% as a fraction or a mixed number fully simplified please
solong [7]

Answer:

135% = 27/20 = 17/20 as a fraction

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

135% = 135/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 135 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(135,100) = 5. So,

(135÷5)/(100÷5) = 27/20 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 135/100 is also equal to 1 7/20 when expressed as a mixed number.

An estimated 40% of all people were born after the year 2000. If two people are selected at random from around the world, what a
sukhopar [10]

The chances that NEITHER of these two selected people were born after the year 2000 is 0.36

<h3>How to determine the probability?</h3>

The given parameters are:

Year = 2000

Proportion of people born after 2000, p = 40%

Sample size = 2

The chances that NEITHER of these two selected people were born after the year 2000 is calculated as:

P = (1- p)^2

Substitute the known values in the above equation

P = (1 - 40%)^2

Evaluate the exponent

P = 0.36

Hence, the chances that NEITHER of these two selected people were born after the year 2000 is 0.36
