a sales clerk wants to make at least $519 . If he makes a base salary of $335 and $10.25 per hour at his part time job how many hours will he have to work?

Answers

Answer:

18 hours at least to reach the goal

Step-by-step explanation:

Well 519 is the lowest objective so lets aim for that

we can make an equation

since base pay is 335 that doesn’t change

We can make x for hours

335+10.25x ≥ 519

SO it can exactly equal or be greater

You’d get 17.95121... and you can’’t work 17.95121 hours so it has to be 18.

Step-by-step explanation:

The solution to the matrix equation ...

[tex]\left[\begin{array}{cc}3&-2\\6&-5\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right] =\left[\begin{array}{c}2\\-1\end{array}\right][/tex]

is shown in the attachment. It is found by multiplying the equation on the left by the inverse of the coefficient matrix.

Answer:

YZ = 8.5∠X = 70.5°∠Z = 19.5°

Step-by-step explanation:

There are a couple of ways to do this. We can find YZ using the Pythagorean theorem, or we can find it using trig functions.

We know from SOH CAH TOA that ...

Cos = Adjacent/Hypotenuse

cos(X) = 3/9 = 1/3

X = arccos(1/3) ≈ 70.5°

Angle Z is the complement of this, so is ...

Z = 90° -70.5° = 19.5°

The length of side YZ can be found from ...

Sin = Opposite/Hypotenuse

sin(X) = YZ/XZ

YZ = XZ·sin(X) = 9·sin(70.5°) ≈ 8.485 ≈ 8.5

In summary, ...

YZ = 8.5; ∠X = 70.5°; ∠Z = 19.5°

What is the slope, m, of the line through (-7, -2) and (-6, 7)?

Answers

Answer:

Slope = 9

Step-by-step explanation:

(-7 , -2) ; x₁ = -7 and y₁ = -2

(-6 , 7) ; x₂ = -6 and y₂ = 7

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9[/tex]

Find Y.
Round to the nearest tenth.

Y ≈ 59.0°

Step-by-step explanation:

Using the Cosine rule

cosY = [tex]\frac{x^2+z^2-y^2}{2xz}[/tex]

with x = 22, y = 20, z = 18

cosY = [tex]\frac{22^2+18^2-20^2}{2(22)(18)}[/tex]

= [tex]\frac{484+324-400}{792}[/tex]

= [tex]\frac{408}{792}[/tex] , then

Y = [tex]cos^{-1}[/tex] ( [tex]\frac{408}{792}[/tex] ) ≈ 59.0° ( to the nearest tenth )

flowers for $9.95. If sales tax is 5%, what will
Maria pay altogether?

1. $16.48

2. $15.70

3. $16.49

4. $16.50

Answers

Step-by-step explanation:

Vicky Bought:

Strawberries $3.50

Carrots $2.25

Flowers $9.95

Subtotal $3.50 + $2.25 + $9.95

= $15.70

5% Sales Tax (5% of Subtotal) = 5/100 x $15.70

= $0.785 (will not round off here as it is not the final answer.)

Total = Subtotal + 5% Sales Tax

= $15.70 + $0.785

= $16.485

= $16.49 (rounded off to nearest cent)
