Rewrite the inequality as

$w$

by adding 4 to both sides.

So, you want to pick only the values that are strictly less than 12, i.e. all of the values except 13.

Answer:

(-3, -6)

Step-by-step explanation:

Coordinate = (x-axis, y-axis)

=(x,y)

identify value of coordinate A at x-axis before y-axis

x-axis of A is in the middle of -2 and -4, thus it is -3

y-axis of A when refer to graph is -6

thus answer is (-3,-6)

Find the

Mazyrski [523]

Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the side length ) then

$\frac{s^2\sqrt{3} }{4}$ = 81 $\sqrt{3}$ ( multiply both sides by 4 to clear the fraction )

s² $\sqrt{3}$ = 324 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

s² = 324 ( take the square root of both sides )

s = $\sqrt{324}$ = 18

Thus

perimeter = 3 × 18 = 54 cm

Work the following pricing problems for services rendered. (For all calculations use hundredths.)

Lesechka [4]

Answer:

Hourly Rate = $12.22 per hour

Step-by-step explanation:

$\text{Labor Time = }4\tfrac{1}{2}=4.5\thinspace{ hours}$

Overhead Rate = 95%

Retail price of parts = $134.75

Total cost of job = $241.98

Cost of labor = Total cost - Retail price

= 241.98 - 134.75

= $107.23

Now, labor works for 4.5 hours and ears a total amount of $107.23

$\implies\text{Amount earned in one hour or hourly rate = }\frac{107.23}{4.5}\\\\\implies \text{Hourly rate = }\$23.83\text{ per hour}$

Now, Labor will get 95% overhead rate

⇒ The labor is getting 100% already but an overhead of 95% is also given

$\text{So, Hourly Rate = }\frac{23.83}{1+0.95}\\\\\bf\implies\textbf{Hourly Rate = }\$12.22\textbf{ per hour}$
