Answer:

46.95 in.²

Step-by-step explanation:

Surface area of the kaleidoscope = surface area of a triangular prism = 2(BA) + P*H

Base area (B) = 2(½*bh) = 2(½*1.5*1.3) = 1.95 in.²

Perimeter of base (P) = 1.5 + 1.5 + 1.5 = 4.5 in.

Height of prism (H) = 10 in.

Plug in the values

Surface area = 1.95 + 4.5*10 = 46.95 in.²

brilliants [131]

Answer:

1\frac{1}{15}

Step-by-step explanation:

\frac{7}{5}+\frac{2}{3}-1\\

Convertir elemento a fracción: 1 = 1/1

=-\frac{1}{1}+\frac{7}{5}+\frac{2}{3}

Mínimo común múltiplo de 1,5,3 = 15

Ajustar fracciones según el mcm

=-\frac{15}{15}+\frac{21}{15}+\frac{10}{15}

Dado que los denominadores son iguales, combine las fracciones:

\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\= \frac{-15+21+10}{15}\\\\

Sumar Restar los números: -15 + 21 + 10 = 16

=\frac{16}{15}\\\\16\div 15 = 1 \: remainder 1\\\\=1\frac{1}{15}

You know the whole and one part.You can blank to find the other part.
Sliva [168]
If you have a part and a whole you can subtract the part from the whole to find the other part.
I'm not sure about it, but that's my best guess ;3
Good luck!
