Answer:

x = 12.8 cm

Step-by-step explanation:

Using the sine ratio in the right triangle to solve for x

sin70° = $\frac{opposite}{hypotenuse}$ = $\frac{12}{x}$

Multiply both sides by x

x × sin70° = 12 ( divide both sides by sin70° )

x = $\frac{12}{sin70}$ ≈ 12.8

Gomez runs a small pottery firm. he hires one helper at $15,000 per year, pays annual rent of $6,500 for his shop, and spends $2

Vadim26 [7]

$15,000+$6,500+$23,000+$20,500+$5,000=$70,000
$70,000+$40,000=$110,000
$110,000-$82,000=-$28,000
economic profit is -$28,000
$82,000-$70,000=$12,000
accounting profit is $12,000

Question 1 (1 point)

For this case we can propose a system of equations:

x: Let the variable that represents the number of small cookies

y: Let the variable that represents the number of large cookies

According to the statement we have:

$x + y = 130\\2x + 3y = 310$

We multiply the first equation by -2:

$-2x-2y = -260$

We have the following equivalent system:

$-2x-2y = -260\\2x + 3y = 310$

We add the equations:

$-2x + 2x-2y + 3y = -260 + 310\\y = 50$

We look for the value of the variable "x":

$x = 130-y\\x = 130-50\\x = 80$

Answer:

They sold 80 small cookies and 50 large cookies
