The prism shown has a volume of 35 cm^3

artcher [175]

Answer:

$Height = 2.5$

Step-by-step explanation:

Given

$Volume = 35$

$Length =7$

$Base=4 cm$

Required

Determine the height

The volume is calculated as:

$Volume = Height * Base\ Area$

Since, it has a triangular cross-section, the expression becomes:

$Volume = Height * \frac{1}{2} * Base * Length$

So, we have:

$35 = Height * \frac{1}{2} * 4 * 7$

$35 = Height * 14$

$Height = 35/14$

$Height = 2.5$

john had a ribbon that was 1 1/2 meters long. he used 2 pieces that were each 1/3 of that length. how much ribbon did john use

Of means multiplication. So the question is 1/3 X 1 1/2. First make 1 1/2 improper: 3/2. Then multiply the numerators (top numbers) and denominaters (bottom numbers): 1x3=3, 3x2=6, =3/6. Now simplify 3/6=1/2. Then multiply that by 2, since he used 2 pieces: 1/2x2=1. John used 1 meter :)
