11. The volume of the triangular pyramid is
, then
.
12. They have common base (common triangle). y=7.7, r=23.1, then r:y=23.1:7.7=3.
13. See 10 and 11 for notations in symbols.
3x = 9y
9y = 3x
y = 3x/9
y = 1/3x
The slope is 1/3
Answer:
D. y= 200+ 0.1x
Step-by-step explanation:
Given data
Fixed Salary= $200
Commission= 10%
weekly sales = x
Hence the expression for the total amount he earns is given as
y= 200+ 0.1x
