Answer:
Siti's money = RM 430
David = RM 1,290
Farid = RM 280
Step-by-step explanation:
Let
Siti's money = x
David = 3x
Farid = x - 150
Total of their money = RM 2 000
x + 3x + (x - 150) = 2000
4x + x - 150 = 2000
5x = 2000 + 150
5x = 2,150
x = 2,150/5
x = RM 430
Siti's money = x
= RM 430
David = 3x
= 3(430)
= RM 1,290
Farid = x - 150
= 430 - 150
= RM 280
Since there is a right angle, you can use Pythagoras' Theorem:
So x = √(24² + 7²) = 25

Answer:
2 5/8 ounces of juice are left.
Step-by-step explanation:
6 3/8 - 3 6/8 =
- 51/8 - 30/8 (Converted into improper fractions.)
- 51/8 - 30/8 = 21/8
- 21/8 = 2 5/8 (Converted improper fraction into a mixed fraction.)
In normal line integration, from what I understand, you are measuring the area underneath (,)
