Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11

Answer:
3.9984i-3.0021j
Step-by-step explanation:
Due to the fact that we are only asked for the components on A, we will focus on that information.
The first thing we need to do is to dimension the magnitud of A as a hypotenuse of a right triangle. As the vector is ponting in south-east direction, we can asume that it´s (i) component will be positive and it´s (j) component will be negative.
Now, using trigonometric functions we can find the components of the vector A by multiplying the magnitude by -sin(x) for (j) and cos(x) for (i).
-5sin(36.9)=-3.0021
(this component is negative due to the fact that the vector is pointing down)
5cos(36.9)= 3.9984
Now we write in the correct notation x(i) + y(j)
3.9984i-3.0021j
Answer:
is answer is 8,340
Step-by-step explanation:
add 280 and 415 and get 695
then multiply by 5 and get 3,475
then multiply 695 by 12 and get 8,340
