Step-by-step explanation:

In a state with a sales tax rate of 6%,

Alex bought paper for his printer for

$17.99.

The amount of his sales tax to the nearest penny is calculated as:

Sales tax rate × Cost of Paper for his printer

Sales tax = 6% × $17.99

= 6/100 × $17.99

=$ 1.0794

Approximately≈ $1.1

Step-by-step explanation:

Answer:

[tex]m\angle B\approx 80.27^\circ\text{ and } m\angle C\approx 59.73^\circ[/tex]

Side AB measures approximately 20.15 units.

Step-by-step explanation:

We can use the Law of Sines, given by:

[tex]\displaystyle \frac{\sin A}{a} = \frac{\sin B}{b} = \frac{\sin C}{c}[/tex]

Since we already know ∠A and a, we can use it to determine our other measures.

We know that b is 23. Substitute:

[tex]\displaystyle \frac{\sin 40^\circ}{15}=\frac{\sin B}{23}[/tex]

Solve for ∠B:

[tex]\displaystyle \sin B=\frac{23\sin 40^\circ}{15}[/tex]

We can take the inverse sine of both sides:

[tex]\displaystyle m\angle B=\sin^{-1}\frac{23\sin 40^\circ}{15}[/tex]

Use a calculator (make sure you're in Degrees mode!):

[tex]m\angle B\approx 80.27^\circ[/tex]

The interior angles of a triangle must total 180°. Hence:

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]

Substitute in known values:

[tex](40^\circ)+(80.27^\circ)+m\angle C=180^\circ[/tex]

Therefore:

[tex]m\angle C\approx 59.73^\circ[/tex]

Lastly, to find AB or c, we can use the Law of Cosines:

[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]

a = 15, b = 23, and to prevent rounding errors, we will use the exact value for C. Recall that we know that:

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]

Using the exact value for ∠B, we acquire:

[tex]40^\circ+\displaystyle \sin^{-1}\frac{23\sin40^\circ}{15}+m\angle C=180^\circ[/tex]

Therefore:

[tex]\displaystyle m\angle C=\left(140-\sin^{-1}\frac{23\sin40}{15}\right)^\circ[/tex]

Substitute:

[tex]\displaystyle c^2=(15)^2+(23)^2-2(15)(23)\cos\left(140-\sin^{-1}\frac{23\sin40^\circ}{15}\right)[/tex]

Simplify and take the square root of both sides.

[tex]\displaystyle c=\sqrt{754-690\cos\left(140-\sin^{-1}\frac{23\sin40^\circ}{15}\right)}[/tex]

And use a calculator:

[tex]c\approx 20.15[/tex]

Answer:

hey im sorry for using this, but there's nothing else. which one was right???/ im stuck

Step-by-step explanation:

Reason: Any two perpendicular lines will have their slopes multiply to -1, where neither line is vertical.

The given line has slope -1/4 and the perpendicular slope is 4

(-1/4)*4 = -1

Put another way: the answer is 4 because it's the negative reciprocal of -1/4.

Radius of circle [tex]r=14\ cm[/tex]

Length of chord is [tex]l=18\ cm[/tex]

Suppose the distance between the chord and center is x

From figure, we can write

[tex]\Rightarrow r^2=x^2+9^2\\\Rightarrow 14^2=x^2+9^2\\\Rightarrow x^2=196-81\\\Rightarrow x^2=115\\\Rightarrow x=\sqrt{115}\\\Rightarrow x=10.72\ cm[/tex]

Answer:

Step-by-step explanation:

For the data collected by Martin from students about whether they played a musical instrument, the relative frequency of a boy playing an instrument is 0.348.

Relative frequency of an event is the measure of something happens relative to the total outcomes of that event.

The relative frequency can be given as,

[tex]f_r=\dfrac{f}{n}[/tex]

Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.

The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.

Martin collected data from students about whether they played a musical instrument.

The table shows his results.

Here, the total number of boys are 92 and the total number of boys who play instrument is 32. Thus, the relative frequency is,

[tex]f_r=\dfrac{32}{92}\\f_r=0.348[/tex]

Thus, for the data collected by Martin from students about whether they played a musical instrument, the relative frequency of a boy playing an instrument is 0.348.
