Answer:
the answer would be 35...
Step-by-step explanation:
Dont know how to explain it on here
Let n = the number of nickels that Ari has.
Let p = the number of pennies that Ari has.
The total number of coins she has is 22.
n + p = 22
We have our first equation... But we another one to solve this.
Each penny is going to be $0.01 and a nickel is work $0.05.
And the total is $0.54
Our second equation. 0.05n + 0.01p = 0.54
n + p = 22
0.05n + 0.01p = 0.54
Multiply the top by -0.05
-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54
The n terms cancel out.
-0.04p = -0.56
p = 14
Substitute p back into the top equation.
n + 14 = 22
n = 8
So, Ari has 8 nickels and 14 pennies.
That is the velocity that the car is travelling at. The car is moving at 65mph.
Answer:
60 °
Step-by-step explanation:
Applying the law of sine we have the following:
160 / Sin B = 80 / Sin 30 °
We solve for B and we have:
160 / Sin B = 80 / 0.5
160 / Sin B = 160
Without B = 160/160
B = Arc Sin (1)
B = 90 °
Now to calculate the other angle (true
course) would be:
A = 180 ° - (B + C)
A = 180 ° - (90 ° + 30 °)
A = 60 °
That is to say that true course is 60 °
