First set up the inequality.
12x + 9 <= 45
subtract 9 from both sides
12x + 9 - 9 <= 45 - 9
12 x <= 36
divide both sides by 12
x < = 3
She can buy at most 3 shirts

If a monopolist can sell 7 units when the price is $4 and 8 units when the price is $3, then marginal revenue of selling the eig
pychu [463]

The marginal revenue of selling the eighth unit is $-4.

A monopolist is the only producer in the industry. A monopolist operates in a monopoly. The monopolist sets the market price of their products.

Marginal revenue is the change in total revenue when quantity sold increases by one unit.

Marginal revenue = change in total revenue / change in quantity sold

change in total revenue = ($3 x 8) - ($4 x 7) = $-4

change in quantity sold = 8 - 7 = 1

Marginal revenue = $-4 / 1 = $4

Find the oth term of the geometric sequence 5, -25, 125,
maxonik [38]

Answer:

-625

Step-by-step explanation:

Here we are basically multiplying each term by -5. So if you want two more terms, you would go like this...

5 × -5 = -25

-25 × -5 = 125

125 × -5 = -625

-625 × -5 = 3125

and so on!!!

Hope it helps and mark it as Brainliest if possible!!! Good Luck!!!

problem: report error when the measures of the angles of a triangle are placed in order, the difference between the middle angle
laiz [17]

The triangle's biggest angle's measurement in degrees is 97°.

What is a triangle?

  • A triangle is a polygon with three vertices and three sides. The angles of such a triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
  • All of the angles in an acute triangle are below 90 degrees.
  • Any angle in an obtuse triangle is larger than 90 degrees.
  • There is just one 90-degree angle in a right triangle.

Let a+b+c=180° with a < b < c

c-b=b-a\\c=2b-a | a=180-b-c\\c=2b-(180-b-c)\\c=2b-180+c+c | -c\\0=2b-180+b\\180=3b\\b=\frac{180}{3} \\b=60

Moving angle c of the triangle,

c=2b-a | a=23, b=60\\c=2(60)-23\\c=120-23\\c=97

The triangle's biggest angle's measurement in degrees is 97°.
