Answer:
Phil should have $41.5 and Phil should give $51.5 to her sister.
Step-by-step explanation:
Given that,
amount of money Phil have = $93
amount of money Phil's sister owed to her friend = 10
$10 of the $93 is going to his sister's friend; that leaves $83 for Phil and his sister.
If they are to finish with the same amount, then each should have half of the Phil's money after she paid $10
So,
83/2
= 41.5 each but since Phil's sister have to give 10 rupees in debt so
41.5+10
= 51.5
So Phil should have $41.5 and Phil should give $51.5 to her sister.

Answer is 3
Answer:
Step-by-step explanation:
Begin to factor by using GCF by finding the greatest common factor. Here it is k.
We will rearrange and factor the trinomial.
The dashed line labeled as 6 is the diameter of the circular part of the figure.
The circumference of a circle is it's perimeter, so we need to find half the circumference first.
The formula for circumference is PI x diameter, since we need half we will divide the total circumference by 2.
Circumference = 3.14 x 6 = 18.85 / 2 = 9.425
Now we add that to the other 3 dimensions for total perimeter:
9.425 + 9 + 9 +6 = 33.425
You may need to round the answer, you didn't say if it needed to be rounded a certain way.
Answer:
c = 27.9
B = 62.13°
C = 89.90°
Step-by-step explanation:
We are given the following values:
A= 121.59°, a = 27.9 cm, b = 52.6 cm
a) Finding side c
We would use Pythagoras Theorem
c² = a² + b²
c = √(a² + b²)
c = √(27.9² + 52.6²)
c = 59.54cm
≈ Approximately = 59.5cm
b) Finding B
We would be using Cosine rule to find Angle B
Cos B = a² + b² - c²/2ab
B = arc cos ( a² + c² - b²/2ac)
B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)
B = 62.13268°
B = 62.13°
c) Finding C
We would be using Cosine rule to find Angle C
Cos C = a² + b² - c²/2ab
C = arc cos ( a² + b² - c²/2ab)
C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)
C = 89.9°
