Answer:
The other rational number is
.
Step-by-step explanation:
First rational number is 
Let other rational number is 
The product of two rational numbers is 
According to question,

Multiplying both sides by (-3/2) such that,

So, the other rational number is
.
Part B
Divide 63 by 3 to get 21, the price of one shirt.
Divide 21 by 7 to get 3, 10% of the original price.
Multiply 3 by 10 to get 30, the original price of one shirt.
Answer: $30
Part C
Divide 40 by 10 to get 4, 10% of original price
Multiply 4 by 3 to get 12, 30% of the original price
subtract 12 from 40 to get 28, the price after discount
Divide 28 by 10 to get 2.8, the second 10% discount.
Subtract 2.8 from 28 to get 25.2, the final price.
Answer: $25.20

Answer:
15.7°
Step-by-step explanation:
The law of cosines can be used to find side s:
s² = r² +q² -2rq·cos(S)
s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903
s ≈ 16.849
Then the law of sines can be used to find angle Q.
sin(Q)/q = sin(S)/s
sin(Q) = (q/s)sin(S)
Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°
Angle Q is about 15.7°.
