The product of two rational numbers is (-28/81). If one of them is (-2/3), the find the other.
KatRina [158]

Answer:

The other rational number is \dfrac{14}{27}.

Step-by-step explanation:

First rational number is \dfrac{-2}{3}

Let other rational number is \dfrac{x}{y}

The product of two rational numbers is \dfrac{-28}{81}

According to question,

\dfrac{x}{y}\times \dfrac{-2}{3}=\dfrac{-28}{81}

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

\dfrac{x}{y}\times \dfrac{-2}{3}\times \dfrac{-3}{2}=\dfrac{-28}{81}\times \dfrac{-3}{2}\\\\\dfrac{x}{y}=\dfrac{14}{27}

So, the other rational number is \dfrac{14}{27}.

Zinaida [17]
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

In ΔQRS, q = 9.4 cm, r = 8 cm and ∠S=151°. Find ∠Q, to the nearest 10th of a degree.
kramer

9514 1404 393

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°.
