Answer:

x ≈ 18.52

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan51° = $\frac{opposite}{adjacent}$ = $\frac{x}{15}$

Multiply both sides by 15

15 × tan51° = x, thus

x ≈ 18.52 ( to 2 dec. places )

Ricky is filling an 8 inch by 4 1/2 inch rectangular box with packing peanuts. The peanuts are cubes that come in two different

Marina86 [1]

Ok, so we can fill the part of the box that corresponds to the 8x4 inches with the boxes that are 1 cubic inch - that wound be 8x4, that is 32 such boxes.

then the rest would be 8x $\frac{1}{2}$ inches, that is 4 cubic inches.

In order to fill in 4 cubic inches with $\frac{1}{8}$ inches boxes we calculate:

$4/ \frac{1}{8}=4*8=32$ So it's also 32 such small boxes!
