Answer:

96m²

Step-by-step explanation:

Hello there!

The figure shown is an irregular figure so to make it easier we are going to split the irregular figure into two regular figures

A triangle with a height of 6 m and a base of 12 m

and a parallelogram with a base of 10m and a height of 6m

Now lets find the area of each individual shape

For the triangle:

The area of a triangle can be calculated using this formula

A=\frac{bh}{2} where b = base and h = height

Knowing the base and height all we have to do is plug in the values into the formula

A=\frac{6*12}{2} \\6*12=72\\\frac{72}{2} =36

so we can conclude that the area of the triangle is 36 m²

Now lets find the area of the parallelogram

The area of a parallelogram can simply be found my multiplying the base and height

so A = 10 * 6

10 * 6 = 60

so the area of the parallelogram is 60 m²

Finally we add the two areas together

60 + 36 = 96m²

Thus the area of the irregular figure is 96m²

adell [148]

Answer:

The price per wind chime that will maximize revenue = $ 315

Step-by-step explanation:

Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.

To find - Find the price per wind chime that will maximize revenue.

Proof -

Given that,

Total Wind chimes selling = 160

Price of each Wind chime = $150

Now,

Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.

So,

Let the price = 150 + 15x

So,

Number of wind Chimes sold per month = 160 - 5x

So,

Total Revenue, R = (150 + 15x)(160 - 5x)

                             = 24000 - 750x + 2400x - 75x²

                             = 24000 + 1650x - 75x²

⇒R(x) = 24000 + 1650x - 75x²

Differentiate R with respect to x , we get

R'(x) = 1650 - 150x

Now,

For Maximize Revenue, Put R'(x) = 0

⇒1650 - 150x = 0

⇒150x = 1650

⇒x = 1650/150

⇒x = 11

∴ we get

Price per Wind chime = $ 150 + 15(11)

                                    = $ 150 + 165

                                    = $ 315

So,

The price per wind chime that will maximize revenue = $ 315

A pedestal in a craft store is in the shape
Angelina_Jolie [31]
Given:
side lengths of right triangles = 12 cm ; 16 cm ; 20 cm
lateral area = 192 cm²

lateral area of a triangular prism = perimeter * height
192 cm² = (12 cm + 16 cm + 20 cm) * height
192 cm² = 48 cm * height
192 cm² / 48 cm = height
4 cm = height

The height of the pedestal in the shape of a triangular prism is 4 cm.
