Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

V=a^2\frac{h}{3}

So its just:

8.8^2\frac{12.5}{3} = 322.67 cm^3

Then you just multiply the volume by the cost per cubic centimetre:

322.67cm^3*$0.12=$38.704

After just multiply the cost of one by how many you want, which is 6:

38/704*6=232.32

A half-circle is joined to an equilateral triangle with side lengths of 12 units. What is the perimeter of the resulting shape?
krek1111 [17]

Answer:

P = 42.84  cm

Step-by-step explanation:

A half-circle is joined to an equilateral triangle with side lengths of 12 units.

We need to find the perimeter of the resulting shape.

The perimeter of the half cirle is πr.

The diameter of the circle is 12. It means radius is 6 units.

An equilateral triangle has 3 equal sides. So, perimeter of the triangle is given by :

P = πr  + 12 +12

= 3.14(6) + 24

= 42.84  cm

Hence, the perimeter of the resulting shape is 42.84  cm.

Solve the equation<br> 0.2(d-6)=0.3d+5-3+0.1d for d
WINSTONCH [101]

Answer:

d= -16

Step-by-step explanation:

To answer this question you'll have to first simplify the equation to

0.2d+-1.2=0.3d+5-3+0.1d

then combining like terms you get

0.2d-1.2=(0.3d+0.1d)+(5+-3)

0.2d-1.2=0.4d+2

then subtract 0.4d from both sides leaving you with

-0.2d-1.2=2

then add 1.2 to both sides

-0.2d=3.2

after you divide both sides by -0.2

leaving you with the answer

D= -16

8.1 Tangent Lines find the side of of triangle KLJ
Stells [14]

Answer:

x=12

Step-by-step explanation:

tangent forms 90° with the touch point at circle

(x+8)^2 = 256+x^2

x^2 + 16x + 64 = 256 + x^2

16x = 192

x= 12
