In the expression 7m/9+6r-4/5 , what are the coefficients ?
2 answers:
Answer:
Coefficients are:
d) 7/9 and 6
Step-by-step explanation:
We are given a expression:
We have to find the coefficients
Coefficient is a term which is multiplied to a variable or its power
Above expression has two variables m and r
The coefficient of m=7/9
and coefficient of r=6
Hence, coefficients are:
d) 7/9 and 6

Check the picture below.
b)
volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.
Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.
Now, what's the ratio of the tiny pyramid to the truncated bottom?
