You but a container of cat litter for 12.25 and a bag of cat food for x dial let's. The total is 19.08 witch includes 6% tax sal

shutvik [7]

Answer:

The price of cat food is 5.75 dial

Step-by-step explanation:

Given as :

The price of container of litter = 12.25 dial

The price of cat food = x dial

The total price of items = 19.08 dial including 6% sales tax

So, The total price of item excluding sales tax is A

Or, A + 6% of A = 19.08

So, 1.06 × A = 19.08

Or, A = $\frac{19.08}{1.06}$

∴ A = 18 dial

Now, The price of cat food = Total price of item excluding tax - price of container of litter

Or, The price of cat food = 18 dial - 12.25 dial

∴ The price of cat food = 5.75 dial

Hence The price of cat food is 5.75 dial Answer

Two stabilizing wires extend from the top of a pole to the ground, forming right triangles on

FrozenT [24]

Answer: the height of the pole is 16.1 m.

Step-by-step explanation:

The scenario is illustrated in the attached photo.

x represents the height of the pole.

y represents the distance from the foot of one stabilizing wire to the foot of the pole.

30 - y represents the distance from the foot of the other stabilizing wire to the foot of the pole.

In solving the triangles, we would apply the tangent trigonometric ratio which is expressed as

Tan θ, = opposite side/adjacent side.

Considering triangle ACD,

Tan 60 = x/y

x = ytan60 = y × 1.732

x = 1.732y- - - - - - - - -1

Considering triangle BCD,

Tan 38 = x/(30 - y)

x = (30 - y)tan38 = 0.781(30 - y)

x = 23.43 - 0.781y- - - - - - - - -2

Substituting equation 1 into equation 2, it becomes

1.732y = 23.43 - 0.781y

1.732y + 0.781y = 23.43

2.513y = 23.43

y = 23.43/2.513

y = 9.3

x = 1.732y = 1.732 × 9.3

x = 16.1 m
