Answer:

              \bold{2+\frac{5i}3-2i=2-\frac{1}3i}

or if you mean (2 + 5i)/(3 - 2i) at complex numbers

              \bold{\dfrac{2+5i}{3-2i}=\dfrac{-4+19i}{13}=-\frac{4}{13}+1\frac{6}{13}\,i}.

Step-by-step explanation:

\bold{2+\frac{5i}3-2i=2+\frac{5i}3-\frac{6i}3=2-\frac{1}3i}

But I think you mean:  (2 + 5i)/(3 - 2i) and complex numbers.

Then:

\dfrac{2+5i}{3-2i}=\dfrac{(2+5i)(3+2i)}{(3-2i)(3+2i)}=\dfrac{6+4i+15i+10i^2}{9+6i-6i-4i^2}=\dfrac{6+19i-10}{9+4}=\dfrac{-4+19i}{13}

Snow cone holders are sold in sleeves of 50. How much paper is needed for each sleeve if the cones have a slant height of 5 inch
Genrish500 [490]

Answer:

The correct answer is

Step-by-step explanation:

Snow cone holders are sold in sleeves of 50.

The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.

Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.

Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.

Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.
