Answer:

[tex]\Huge\boxed{24cm^2}[/tex]

Step-by-step explanation:

Hello There!

The following figure shown is a composite figure (meaning we can't find the area of it using one formula)

So in order to find the total area we are going to want to split the figure into 3 shapes

A rectangle with a width of 3 and a length of 4 (found by subtracting the total length of the composite figure by the triangles length 8-4=4 so the length of the rectangles are 4 cm

Another rectangle with a width of 1.5 and  a length of 4 ( once again found by subtracting the total length of the composite figure by the triangles length 8-4=4 so the length of the rectangles are 4 cm )

And a triangle with a height of 4 and a base of 3

Now lets find the area of each individual shape

for rectangle #1

The area of a rectangle can easily be calculated by multiplying the length and width

so A = 3 x 4

3 x 4 = 12 so the area of the larger rectangle is 12 cm^2

for rectangle #2 Once again the area of a rectangle can simply be found my multiplying the length and the width

So A = 1.5 x 4

1.5 * 4 = 6 so the area of the smaller rectangle is 6 cm^2

For the triangle

We can solve for the area of a triangle using this formula

[tex]A=\frac{bh}{2}[/tex]

where b = base and h = height

we already know the length of the base and height so all we have to do is plug in the values into the formula

so

[tex]A=\frac{4*3}{2} \\4*3=12\\\frac{12}{2} =6[/tex]

So the area of the triangle is 6 cm ^2

finally we want to add all of the areas together

6 + 6 + 12 = 24

So the total area of the composite figure is 24 cm ^2

Answer:

230.5

Step-by-step explanation:

Formulas: a = 1/2(bh), a = bh

Rectangle 1: a = 6 x 8

a = 48

Base of the triangle: 9 + 6

15

Triangle 1: a = 1/2(15 x 24)

a = 180

Triangle 2: a = 1/2(4(13 - 8))

a = 2.5

48 + 180 + 2.5

230.5

The area of the figure is 230.5.

Answer:

108 is the answer and there is no explanation for this. Youc can directly multiply it.

Answer:

648

Step-by-step explanation:

There is no distributive property necessary. You would use distributive property in a problem like a(b + c).

a(b + c)

ab + ac

That is distributive property. 6 × 108 doesn't require distributive property.

6 × 108 or 6(108) or 108(6) = 648

Answer:

The area of the base of the pyramid is 109.2 mm.

Step-by-step explanation:

The area of the base of a hexagonal pyramid is given by the area of a hexagon:

[tex] A_{b} = \frac{P*a}{2} [/tex]  

Where:

P: is the perimeter

a: is the apothem

We need to find the perimeter and the apothem.

The perimeter is equal to:  

[tex] P = 6*s [/tex]

Where:

s: is the side of the pyramid

And the apothem is:

[tex] a = \frac{\sqrt{3}}{2}*s [/tex]

So, to calculate the apothem and the perimeter we need to calculate the side of the pyramid. We can find it from the volume of the pyramid:

[tex] V = \frac{\sqrt{3}}{2}*h*s^{2} [/tex]  

Where:

h: is the height = 4 mm  

V: is the volume = 144 mm³                                  

Then, the side is:  

[tex] s = \sqrt{\frac{2V}{\sqrt{3}*h}} = \sqrt{\frac{2*144}{\sqrt{3}*4}} = 6.5 mm [/tex]

Now, we can find the perimeter and the apothem.

[tex] a = \frac{\sqrt{3}}{2}*s = \frac{\sqrt{3}}{2}*6.5 = 5.6 mm [/tex]

[tex] P = 6*s = 6*6.5 = 39 mm [/tex]

Finally, the area is:

[tex] A_{b} = \frac{P*a}{2} = \frac{39*5.6}{2} = 109.2 mm^{2} [/tex]

Therefore, the area of the base of the pyramid is around 109 mm.

I hope it helps you!

Step-by-step explanation:

Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

To solve the problem, we can use the concept of weighted averages. The first step is to determine the amount of nickel in each metal before they are combined.

For the 20% nickel metal, 20% of the metal is nickel. Therefore, the amount of nickel in x pounds of this metal is 0.2x.

For the 80% nickel metal, 80% of the metal is nickel. Therefore, the amount of nickel in 6 pounds of this metal is 0.8(6) = 4.8 pounds.

Next, we can use the weighted average formula to determine the amount of nickel in the alloy:

0.2x + 4.8 = 0.6(x + 6)

Simplifying the equation:

0.2x + 4.8 = 0.6x + 3.6

0.4x = 1.2

x = 3

Therefore, Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

In summary, to determine the amount of metal-containing 20% nickel needed to combine with 6 pounds of metal containing 80% nickel to form an alloy containing 60% nickel, we used the concept of weighted averages and found that Kaylie needs 3 pounds of the 20% nickel metal.
