Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.
lesantik [10]

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

A = \frac{1}{2} bh

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

A = \frac{1}{2} (22)(23.1) sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

A = \frac{1}{2} (31.9)(15.9) sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) \frac{1}{2} (22)(23.1) and

b) \frac{1}{2} (31.9)(15.9)

Suppose that the demand Q^Dand supply Q^Sfor maize meal in Kimberley is given by p=120-0.7Q^Dand p=3+0.2Q^S where the quantity i
bixtya [17]

Answer:

  20 rands/kg

  130,000 kg

Step-by-step explanation:

The equilibrium quantity and price are the solution to the system of equations ...

  p = 120 -0.7q

  p = 3 + 0.2q

Setting these equal, we get ...

  0.2q +3 = p = -0.7q +120

  0.9q = 117 . . . . . . . add 0.7q-3 to both sides

  q = 117/0.9 = 130

  p = 3 +0.2·130 = 29

The equilibrium price of maize meal is 29 rands per kg; the market equilibrium quantity is 130,000 kg.
