zimovet [89]3 years ago
7 0

Answer:

1 {x+2y= -14

2{x-y=13

x+2y= -14

2x-2y= 26

3x= -14+26

3x/3= 12/3

x= 4

while x-y=13

4-y=13

-y= 13-4

-y=9

-y/-1=9/-1

y= -9

Express 240 as a product of prime factors.
Sholpan [36]

Answer:

240 = 2 x 2 x 2 x 2 x 3 x 5 or 2^4x3x5

Step-by-step explanation:

               240

              /      \

            2      120                     (240 = 2 x 120)

                   /      \

                 2       60                 (120 = 2 x 60)

                        /      \

                      2       30            (60 = 30 x 2)

                             /      \

                           2       15       (30 = 2 x 15)

                                  /      \

An isocost line will be shifted further away from the origin:_______.
otez555 [7]

Answer:

D. All the above are correct

Step-by-step explanation:

An isocost line will be shifted further away from the origin if the total cost increases, if the price of both inputs increases or there is an advance in technology.

An isocost line can be defined as the graphical representation of various combinations of two inputs factors (labor,L and capital, K) which the firm can afford or purchase with a given amount of money.

An isocost line can be expressed mathematically as:

C = w L + r K

Where,

C = cost of production

w = price of labor or wages

L = units of labor

r = price of capital or interest rate

K =units of capital

Isocost is used to determine what combination of factor inputs the firm will choose for production process.

A triangle has a perimeter of 56 cm. Each of the two longer sides of the triangle is three times as long as the shortest side. W
bagirrra123 [75]

The lenght of each side is 24cm, 24cm, and 8cm.

In order to solve this problem, we know that the perimeter of a triangle equation is P = a + b + c, where a, b, and c are the sides of the triangle.

The perimeter is 56cm, we can write the equation as follow:

a + b + c = 56cm (1)

If each of the two longer sides of the triangles is three times as long as the shortest side, we can assume:

c = shortest side = x

a = b = longer sides = 3x

Substituting the values in the equation (1):

3x + 3x + x = 56cm

7x = 56cm

x = 56cm/7 = 8cm

c = shortest side = 8cm

a = b = longer sides = 3(8cm) = 24cm
