write a simplified expression


the 3 children in a family each paid $5 to enter a country fair , and then each child plays games at $1.50 per game. what expression represents the total amount in dollars the children spent all together

The Revenue function for the number of jerseys x sold is ; R(x) = 90x

The profit function from the sale of x jerseys is ; P(x) = - 0.2x² + 80x - 1500

The number of Jerseys to manufacture in other to make profit = 20

The revenue made is the total amount made from the sale of the hickey jerseys :

Sales price per jersey = $90

Hence, the revenue made, R(x) = 90x

The Cost function, C(x) = C(x) = 1500 + 10x + 0.2x²

Recall :

Profit = Revenue - Cost

Hence,

P(x) = R(x) - C(x)

P(x) = 90 - (0.2x² + 10x + 1500)

P(x) = 90 - 0.2x² - 10x - 1500

P(x) = - 0.2x² + 80x - 1500

To make profit, equate P(x) to 0 ;

0.2x² - 80x + 1500 = 0

Using a quadratic calculator :

x = 380.22 or x = 19.72

Hence, to make a profit, the number of jerseys that must be sold is 20.

Answer:

108 cm²

Step-by-step explanation:

Area of a rectangle, A = length, l × width, w

Perimeter of a rectangle = (2 × length) + (2 × width)

42 cm = 2l + 2w

but length = w + 3cm

42 cm = 2(w + 3cm) + 2w

42 cm = 2w + 6cm + 2w

42 cm = 6cm + 4w

4w = (42 - 6) cm

4w = 36 cm

》w = 9cm

》l = w + 3cm = 9cm + 3cm

l = 12 cm

Area = 12 × 9 = 108 cm²

Answer:

13

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180

       -11     -11

Answer:

  A

Step-by-step explanation:

It is generally useful to look at the answer choices. Here, we observe that all of them have y with a positive coefficient on the left side of the inequality. This makes it relatively easy to choose the set of inequalities that matches the graph.

The shading is below the solid line and above the two dashed lines. This means we are looking for a set of inequalities that looks like ...

  ay + ( ) ≤ ( ) . . . . . shading below a solid line

  y + ( ) > ( ) . . . . . . shading above a dashed line

  y + ( ) > ( )

The only set of inequalities with these relationships is choice A.

Answer:

11

Step-by-step explanation:

area of square is side length squared so [tex]\sqrt{120}[/tex] =10.95 or approximatly 11

a= 9/11 and b=7/10

now,

ab = (9/11)×(7/10)

=63/110.......

the value of ab is 63/110 when a = 9/11 and b = 7/10

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, the values of a and b are 9/11 and 7/10 respectively

thus,

ab = 9/11 * 7/10

simplifying it

ab = 63/110

Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10
