Hello! And thank you for your question!
First to make the question more easy to understand. We are going to make these three fractions improper fractions.
To do this I will give an example. 3 1/6. Do 6*3+1=19/6
Equation after made improper:
19/6 + 74/9 - 3/2
Now that we have this we can find the answer!
-------------------------------------
Work:
First you are going to find the LCD. And change all the numbers denominators to that LCD.
LCD = 18
Equation After incorporating LCD:
57/18 + 148/18 - 27/18
Second we are going to add all of the numerators together to get:
178/18.
Then simplify 178/18 to get:
89/9
Then convert 89/9 to a mixed fraction:
9 8/9
Final Answer:
9 8/9
9 sq. units refers to a 2d figure
9 cubed units refers to a 3d figure
so
9*9 would be sq. unit cuz dimensions of square
9*9*9 would be cubed unit cuz dimensions of cube
so in simple, 9^2,
and 9^3
Answer:
Step-by-step explanation:
Given
Angelo drew a model with his drawing length 10 inches tall
The actual pole length is 15 feet tall
drawing scale is the ratio of drawing length to the actual length i.e.
Answer:
2:1 should be the scale factor
Step-by-step explanation:
The original area is 72cm^2 and the trapezoid shown is 36cm^2. 72/2=36 so the scale factor is 2:1 or 1/2 the original trapezoid.
