A. Square because 90 degree angles are right angles and all of a square’s angles are equal.

A square is a quadrilateral that has 4 angles that is 90 degrees.

Are the angles complementary, supplementary, or neither? What's the answer? Photo below.

I personally would say neither because they either aren't the same or there not equivalent.

There are 6 times as many males as females on the maths course at university what fraction of the course are male?

WITCHER [35]

Answer:

Let M represents the Male and F represents the Female.

As per the statement:

There are 6 times as many males as females on the maths course at university.

⇒ M = 6F

Total number of person on the maths course = M + F = 6F+ F = 7F

we have to find the fraction of the course are male;

$\text{Fraction of the course are male} = \frac{\text{Number of males on the maths course}}{\text{Total number of person on the course}}$

Substitute the given values we have;

$\text{Fraction of the course are male} = \frac{6F}{7F} = \frac{6}{7}$

therefore, the fraction of the course are male is, $\frac{6}{7}$

Self explanatory solve porfavor

inessss [21]

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

-2

The probability that one of each color is selected is $\frac{10x - x^2}{45}$

<h3>Probabilities</h3>

The probability of an event is the chances of the said event

The given parameters are:

Total = 10
Red = x
Blue = 10 - x

<h3>Calculating the required probability</h3>

The probability that one of each color is selected is calculated as follows:

$P = P(Blue) \times P(Red) + P(Red) \times P(Blue)$

So, we have:

$P = \frac{10 - x}{10} \times \frac{x}{9} + \frac{x}{10} \times \frac{10 - x}{9}$

This gives

$P = \frac{x(10 - x)}{90} +\frac{x(10 - x)}{90}$

Take LCM

$P = \frac{2x(10 - x)}{90}$

Simplify the above expression

$P = \frac{x(10 - x)}{45}$

Expand

$P = \frac{10x - x^2}{45}$

Hence, the probability that one of each color is selected is $P = \frac{10x - x^2}{45}$
