Answer:

5.375

Step-by-step explanation:

The mean of average represents $\frac{sum -of-all-numbers}{total-numbers}$ . We see that there are a total of 8 numbers, so: $\frac{3+7+12+9+3+6+2+1}{8}=\frac{43}{8} =5.375$

25% is equal to 1/4.
Therefore, you divide $51 by 3 as 1/4 of the price has already been discounted.
That comes out to $17 p[er 1/4 of the jeans.
You multiple $17 by 4 to get 100% (the full price) which would be $68. So you're answer is, $68 was the original price.

Monica [59]

Answer:

6852 feet .

Step-by-step explanation:

Refer the attached figure

The chairlift at a ski resort rises a total of 2600 feet from where it starts. i.e.AB = 2600 feet

The angle of elevation is about 22.3 degrees.i.e.∠ACB= 22.3°

We are supposed to find How far do riders travel on the lift i.e.AC

In ΔABC

We will use trigonometric ratio

$Sin\theta =\frac{Perpendicular}{Hypotenuse}$

$Sin22.3^{\circ} =\frac{AB}{AC}$

$AC=\frac{2600}{Sin22.3^{\circ}}$

$AC=\frac{2600}{0.379456159529}$

$AC=6851.9$

So, riders travel 6852 feet .

The diagram shows an awning on the front of a building. The top of the awning makes a 40° angle with the building. The base of t

slamgirl [31]

Answer:

Height of the awning = 9.52 feet

Step-by-step explanation:

For better understanding of the solution, see the attached diagram of the problem :

According to the figure, AB is the height of the awning

Now, the base of awning will be perpendicular to the building

⇒ m∠ABC = 90°

In ΔABC, By using angle sum property of a triangle

m∠ABC + m∠ACB + m∠BAC = 180°

⇒ m∠ACB = 50°

$Now,\tan 50=\frac{Perpendicular}{Base}\\\\tan 50=\frac{AB}{8}\\\\\implies AB=8\times \tan 50\\\\\bf\implies AB=9.52 \textbf{ feet}$

Hence, Height of the awning = 9.52 feet

Does the equation below define a linear function? y = 3/x, when x ≠ 0

Arisa [49]

we know that

Linear function:

A linear function is a function whose graph is a straight line, that is a polynomial function of degree at most one

For exp: $y=mx+b$

Here , we are given

$y=\frac{3}{x}$

we can see that

x is in denominator

so, this can not be linear function........Answer
