Answer:
6/7
Step-by-step explanation:
If you want the slope of the line on a graph when x is the independent variable, then solve for y:
-28y = -24x +14 . . . . . . . . . . . subtract the x-term
y = (-24/-28)x +14/(-28) . . . . . divide by the y-coefficient
y = 6/7x -1/2
The "rate of change" is the coefficient of x, 6/7.
6 and 8 go into 6 and 8 once. 6 goes into 12 2 times.
Answer:
250 cards
Step-by-step explanation:
Let the number of baseball cards he originally had be x.
He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:
x - (20/100 * x) = x - 0.2x = 0.8x
During week two he bought 20% more cards than he had after week one. This means that after week two, he had:
0.8x + (20/100 * 0.8x)
= 0.8x + (0.2 * 0.8x)
= 0.8x + 0.16x = 0.96x
He now has 10 fewer cards. This means that:
x - 10 = 0.96x
Collecting like terms:
x - 0.96x = 10
0.04x = 10
=> x = 10/0.04 = 250
He had 250 cards originally.
Answer:
The diameter is 13.88 feet.
Step-by-step explanation:
1. The formula for calculate the volume of a sphere is:
Where is the radius.
2. The diameter is:
3. So, you must solve for the radius in the first equation:
4. Then, the diameter is:
