ad-work [718]

Answer:

100 or 150 units of the product.

Step-by-step explanation:

R = x(1000-4x)

What is the value of x if R = 60,000?

x(1000-4x) = 60000

-4x^2 + 1000x = 60000

x^2 - 250x = -15000

x^2 - 250x + 15000 = 0

Factorize:

(x-100)(x-150) = 0

x-100 = 0 V x-150 = 0

x = 100 V x = 150

Usimov [2.4K]

Answer:the number of adult tickets that were sold is 321

the number of adult tickets that were sold is 227

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of adult tickets that were sold.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. This means that

x + y = 548

A adult's ticket was $6.50 while a child's ticket was $3.50. In total, they took in $2881 in sales of these ticket. This means that

6.5x + 3.5y = 2881 - - - - - - - - -1

Substituting x = 548 - y into equation 1, it becomes

6.5(548 - y) + 3.5y = 2881

3562 - 6.5y + 3.5y = 2881

- 6.5y + 3.5y = 2881 - 3562

- 3y = - 681

y = - 681/-3 = 227

Substituting y = 227 into x = 548 - y, it becomes

x = 548 - 227 = 321

The width of a rectangle is one half its length. The perimeter of the rectangle is 54 cm. What are the width and length of the

lord [1]

Answer:

Length of rectangle = 18 cm

Width of rectangle = 9 cm

Step-by-step explanation:

Let the length of rectangle be x

$\therefore \: width \: (w) = \frac{1}{2} x \\ \\ perimeter \: of \: rectangle = 54 \: cm \\ \therefore \:2(l + w) = 54 \\ \therefore \:(l + w) = \frac{54}{2} \\ \therefore \:l + w= 27 \\ \\ \therefore \:x + \frac{1}{2} x = 27 \\ \\ \therefore \:\frac{3}{2} x = 27 \\ \\ \therefore \:x = 27 \times \frac{2}{3} \\ \\ \therefore \:x = 9 \times 2 \\ \\ \huge \red{ \boxed{\therefore \:x = 18}} \\ \\ \implies \: \frac{1}{2} x = \frac{1}{2} \times 18 = 9$

Hence

Length of rectangle = 18 cm

Width of rectangle = 9 cm
