Steps:
1. First you have to find the volume of the rectangular prism (l • w • h). 14 • 5 • 2= 140
2. Then you have to find the volume of the triangular prism (1/2a • c • h). 4 • 5 • 14= 280. 280 / 2= 140.
Both the volume of the rectangular prism and the triangular prism is 140

A butterfly is 1 1/2 inches long and 1 2/3 inches wide. Lashay makes a scale drawing of the butterfly that is 1 inch long. What is the width of his drawing?
Answers
Answer:
1 1/9 inches
Step-by-step explanation:
The scale of the drawing is the ratio of the drawing size to the actual size. It applies to all drawing dimensions. This lets us write a proportion for the width of the drawing.
__
setupdrawing size / actual size = (1 in)/(1 1/2 in) = (width)/(1 2/3 in)
solutionMultiplying by 1 2/3 in, we find the width to be ...
width = (1 2/3 in) × (1 in)/(1 1/2 in)
width = (5/3 in)×1/(3/2) = (5/3 in)(2/3) = 10/9 in = 1 1/9 in
The width of the drawing is 1 1/9 inches.

if this helpful pleas give brainliest!
Answer:
3/4 ( [tex]\frac{3}{4}[/tex] )
Step-by-step explanation:
[tex]\frac{9}{12}[/tex] ÷ [tex]\frac{n}{n}[/tex] = [tex]x[/tex]
to find what to divide 9/12 by first, find their factors
9 - 1, 9, and 3
12 - 1, 12, 2, 6, 3, and 4
since both have 1 and 3 in common, divide by 3
so n (the value you're looking for) is 3
n = 3
[tex]\frac{9}{12}[/tex] ÷ [tex]\frac{3}{3}[/tex] = [tex]\frac{3}{4}[/tex]
x = [tex]\frac{3}{4}[/tex]

IF 2x3x4=24 then what is 6x4
Answers
Then 6 x 4 = 24 too
Answer:

Step-by-step explanation:
This can be explained very simply.
Case 1 : 2 x 3 x 4 = 24
Case 2 : 6 x 4 = ?
We know that the product of 2 x 3 is 6. Therefore, in Case 1 and Case 2, when both 2 x 3 and 6 are multiplied by 4, they should give the same result. Hence, 6 x 4 is 24.
