Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
Answer:
c = $0.8
Step-by-step explanation:
Let
cost of material = c
Diameter = d
c = k*d²
If it costs the manufacturer $0.45 for the material of a Frisbee with a 9-inch diameter
c = k*d²
0.45 = k * 9²
0.45 = k * 81
0.45 = 81k
k = 0.45/81
k = 0.0055555555555
what is the cost for the material for a Frisbee with a 12-inch diameter
c = k*d²
c = 0.0055555555555 * 12²
c = 0.0055555555555 * 144
c = $0.8
The numbers displayed are written in scientific form, so I'll re-write in standard form to display the difference.
6 X

= 600,000. 2 X

= 2,000
One has a few more zeroes, making all the difference because the larger you're working with, the greater the distance.
Really, if what you wanted was the difference, then the answer is simply 598,000.
Hope this explanation helps!
Yes, because when you multiply 5 weeks by 7 days in a week, you get 35 days. It is equivalent.
Answer:
original price is 48 dollars which is 100% cost. we know that 12 is 1/4 of 48 so 1/4 of 100% gives 25%.
