Suppose the graph represents the plans for a fence that Tara is
bagirrra123 [75]

The scale factor of 0.75 would ensure that the new fence has a smaller area

The total cost of fencing the smaller area is $1610.28

<h3>How to determine the fencing cost?</h3>

From the complete question, we have the following parameters:

  • Number of units on the smaller area, k = 12
  • Scale factor = 0.75
  • Unit cost = $6.39 per yard
  • Perimeter, P = 28 yards

Start by calculating the perimeter of the smaller area using:

Smaller Area = Perimeter * Scale factor * k

Where k represents the number of units on the smaller area

So, we have:

Smaller Area = 28 yards * 0.75 * 12

Evaluate the product

Smaller Area = 252 yards

The total cost is then calculated as:

Total cost = Unit cost * Smaller Area

This gives

Total cost = 6.39 * 252

Total cost = $1610.28

Hence, the total cost of fencing is $1610.28

Look at the triangular prism below. Each triangular face or the
Goryan [66]

Answer:

The volume of the triangular prism is V=72\ cm^3

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

V=BL

where

B is the area of the triangular face

L is the length of the prism

step 1

Find the area of the triangular face

The area of a triangle is equal to

B=\frac{1}{2} bh

we have

b=3\ cm\\h=4\ cm

substitute

B=\frac{1}{2}(3)(4)=6\ cm^2

step 2

Find the volume

we have

B=6\ cm^2

L=12\ cm

substitute in the formula of volume

V=6(12)

V=72\ cm^3

A shooting star forms a right triangle with the Earth and the Sun, as shown below:
frez [133]

The positions of the sun, earth and shooting star form a right angled triangle, where distance between earth and sun is 'y', and the angle 'x°' is given

Now, in a right angled triangle using trigonometry, we can determine a side of the triangle is one of the sides and one of the angles is known

Here, if we use cos x = \frac{Base}{Hypotenuse} we can determine the distance between the shooting star and the sun. This can be done because we know that the base is 'y', the angle is x° and the hypotenuse represents the distance between the sun and the shooting star

Note: cos values for each x are definite.
