90 + 20x + 10x = 180
30x = 90
x = 3
The answer is B. Fluid ounces in a pinto fluid ounces in a gallon
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:
4 girls have short red hair
Step-by-step explanation:
Total number of guests at the party is 32
1/2 of the guests are boys
The number of girls with long hair is
= 32×1/4
= 8 girls.
The number of girls with short blonde hair is:
= 16×1/4
= 4 girls
Therefore, we apply the formular below to calculate the maximum number of girls with short red hair.
Total number of girls- ( girls with long hair+ girls with short blonde hair)
= 16-(8+4)
=16-12
= 4
Thus, 4 girls have short red hair
The equation will shift up two points
