Answer:

230.73m^2

Step-by-step explanation:

A=2a^2+4ah=2*4^2+4*4*4=96m^2 (square prism)

A=2\pi rh+2\pi r^2=2*\pi *4*9+2*\pi *4^2 = 326.73m^(cylinder)

326.73-96=230.73m^2 (\frac{3}{4} cylinder)

Marc wants to guess how many marbles are in a box that has a height of 18 inches. He calculates that there are 32 marbles in a h
Rainbow [258]

So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.

\frac{32}{5} = \frac{x}{18}

To get from 5 to 18, you multiply by 3.6.

Do the same thing to the numerator; 32 × 3.6 = 115.2.

Since 0.2 marbles is no marbles, you round down.

There are 115 marbles in the box.

♡ Hope this helps! ♡

Which of the following expressions are equivalent to -19/8 x(-50)
dmitriy555 [2]

1. Move the negative sign to the left.

-
\frac{19}{8}X*-50

2. Use this rule: \frac{a}{b}*\frac{c}{d}=\frac{ac}{bd}

-\frac{19x*-50}{8}

3. Simplify -  \frac{-950x}{8}

4. Move the negative sign to the left.

-(-950x/8)

5. Simplify 950x/8 to 475x/4

6. Remove parentheses.
