Answer:
16 cards in 1 hour
Step-by-step explanation:
8 cards, 1/2 hour
16 cards in 1 hour
Make a proportion.
8/30min= x/60min
Solve the proportion by cross- multiplying.
30x=480
3x=48
x=16
Answer: 11,700 times
Step-by-step explanation:
First find the number of seconds in 3 minutes 15 seconds.
Each minute is 60 seconds so 3 minutes would be:
= 3 * 60
= 180
Add the 15:
= 195 seconds
Lightning strikes more than 60 times per second so we shall use 60 times
= 60 * 195
= 11,700 times
Answer:
Step-by-step explanation:
f ( x ) = 3 x ^ { 3 } - 5 x ^ { 2 } + x - 2 g ( x ) = x + 2
Subtract 3x³ from each sides.
-5x^{2}+x-2gx=x+2-3x^{3}
Add 5x² to both sides.
x-2gx=x+2-3x^{3}+5x^{2}
Subtract x from both sides.
-2gx=x+2-3x^{3}+5x^{2}-x
Combine x and -x to get 0.
-2gx=2-3x^{3}+5x^{2}
The equation is in standard form.
\left(-2x\right)g=2+5x^{2}-3x^{3}
Divide both sides by -2x.
\frac{\left(-2x\right)g}{-2x}=\frac{2+5x^{2}-3x^{3}}{-2x}
Dividing bu -2x undoes the multiplication by -2x.
g=\frac{2+5x^{2}-3x^{3}}{-2x}
Divide 2-3x³ +5x² by -2x.
g=\frac{3x^{2}}{2}-\frac{5x}{2}-\frac{1}{x}
