Features of a Parabola
The equation of a parabola can be written as:
Answer:
b,,,,,d
Step-by-step explanation:
number of bags times how much it carries so the result equals kg hold
so we must the number 10 always so substitute in each equation to get the number 10
Label the 3 distinct sides of the box. I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:
ab=54 in^2
ac=90 in^2
bc=60 in^2
Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c. Then the volume of the box is a*b*c.
Example: bc = 90, but c = 60/b. You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.
Continuing this procedure, I determined that a=9, b=6 and c=10. Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)
Step-by-step explanation:
Cost of white shirt=$15
Cost of tie-dye shirt = $20
Total number of shirts= 500
Total number of white shirts= 200
Cost of white shirts = 200×15=$ 3000
Total number of tie-dye shirts = 300
Cost of tie-dye shirts = 300×20= $6000
Verification:
3000+6000=$9000 proved!
