Answer:
4x+30, 1.875
Step-by-step explanation:
x+(x+30)+2x = 4x+30
4x+30=37.5
4x=7.5
x=1.875
Answer:
Yes they are directly proportional quantities.
Step-by-step explanation:
We find the area of a square by;
A = length squared or (L)² , where 'L' stands for length and 'A' stands for area.
So Area = L²
Assume the length is a units and increase the length by 2 units
The initial area before increasing the length is a²
After increasing the length, the area becomes: (a + 2)² = a² + 4a + 4
Now we subtract the initial area from the final area and get;
(a² + 4a + 4) - a² = 4a + 4
So the new area increases by 4a + 4 units.
Hence, the area increases as the length increases implying that the area of a square is directly proportional to its length.
We denote this proportionality as;
A ∝ L
Answer:
Option A. Ahmed wins the chess game
Step-by-step explanation:
we know that
The probability of Ahmed winning the chess games is 45%
45%=045/100=0.45
The probability of Ahmen winning the checkers games is 0.36
Compare the probability
0.45> 0.36
so
Is more likely that Ahmed wins the chess game
Answer:
a) 7 members,
b) 3.
c) 4.
Step-by-step explanation:
I hope the following will help you understand what this diagram means:-
The 4 people in the area overlapped by the Music and Spanish areas are the people who are in both clubs.
Obaid and Abdulraheem are in the Music Club only.
The number of members in the Music Club is these 2 plus the 4 in the overlap area, so there are 6 members in the Music Club.
