Answer:
Step-by-step explanation:
No of saves in 3 games = 12
Rate of saves per game = 12 ÷ 3 = 4
Answer:
The width will be 
Step-by-step explanation:
Thinking process:
Let the model be:
factoring out 4 gives:
Factorizing the expression in the parentheses gives:
Therefore, since the expression in the parentheses cannot be factorized further, the expression is:
Answer:
dz / dt = -50
Step-by-step explanation:
To solve the chain rule must apply, we have all the necessary values to make the calculation, as follows:
using the chain rule, we find:
dz / dt = (∂z / ∂x) * (∂x / ∂t) + (∂z / ∂y) * (∂y / ∂t)
Evaluating when t = 9, we have to:
fx (6, 4) * g '(9) + fy (6, 4) * h '(9)
We know that g '(9) = −6; h '(9) = 4; fx (6, 4) = 9; fy (6, 4) = 1
Replacing:
(9 * -6) + (1 * 4) = -50
Por lo tanto dz / dt = -50
3500 x 120% = 4200
4200 - 900 = 3300
3300 ÷ 6 = 550 <<< answer
hope it helps!
Answer:
20% off
Step-by-step explanation:
If the initial price was $30, then 10 percent of 30 is 3. If you want to take away 6 dollars, then that's double the percentage and the discount would be 20%.
