Answer:

C.14¾

3 9⁄10

Step-by-step explanation:

\frac{4}{5}  + 3 \frac{1}{10}  =  \frac{8}{10}  + 3 \frac{1}{10}  = 3 \frac{9}{10}

4 \frac{7}{12}  + 2 +  \frac{3}{4}  + 7 \frac{5}{12} =  13 \frac{12}{12}  +  \frac{3}{4}  = 14 +  \frac{3}{4}  = 14 \frac{3}{4}

I am joyous to assist you anytime.

Which statement about the net is true?
Schach [20]
The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles

If you fold this net up, you will get a triangular prism, NOT A PYRAMID.

A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.

Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.

For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.

Because a pyramid is where all the triangles must meet up at a point.

Hope this helps!

Pls help show work please
Aloiza [94]
Each bracelet is $5, this can be represented as 5b. (Where b is number of bracelets)

Each necklace is $8, this can be represented as 8n. (Where n is number of necklaces)

We know that the total money raised needs to be at least $100, but it can also be more than that.

So we know that 8n+5b will be greater than or equal too 100.

8n+5b ≥ 100
