Answer:
22 degrees to the nearest degree.
Step-by-step explanation:
Use the Cosine Rule
3^2 = 5^2 + 7^2 - 2*5*7*cos T
9 = 74 - 70 cos T
cos T = (74-9)/ 70
cos T = 65/70
m < T = 21.8 degrees.
Answer:
115.6
Step-by-step explanation:
115.6, this would be your answer because 17 hours × 6.8 would get you 115.6
so 17 × 6.8 = 115.6
The best way to solve is by using elimination method.
20x = -58 - 2y
17x = -49 - 2y
Multiply second equation by -1
20x = -58 - 2y
-17x = 49 + 2y
Add equations.
3x = -9
Divide.
x = -3
Plug in -3 into one of the equations.
17(-3) = -49 - 2y
-51 = -49 - 2y
Add 49 to both sides.
-2 = -2y
Divide.
1 = y
So your solution is (-3, 1).

Answer:
Bailey's balance after 180 days is $ 157.39.
Step-by-step explanation:
Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:
365 = 100
180 = X
180 x 100/365 = X
18,000 / 365 = X
49.31 = X
22 x 0.4931 = 10.84
142 x 1.1084 = X
157.39 = X
Thus, Bailey's balance after 180 days is $ 157.39.
