Assuming you mean:
Alex has 48 stickers. This is 6 times number of stickers Max has. How many stickers does Max have?
48 divided by 6 gives you 8.
According to the recipe the ratio of sparkling water to grape juice = 1 1/2 : 3/4.
Let us convert 1 1/2 into improper fraction and that is 3/2.
Now, 3/2: 3/4 or 3/2 ÷ 3/4 = 3/2 × 4/3 = 2/1 or 2:1.
Therefore, sparkling water quantity is two times of the quantity of grape juice.
Now, we need to find the number of quarts of sparkling water need to mix in 9 quarts of grape juice.
Since, sparkling water quantity is two times of the quantity of grape juice.
And now we need to find the number of quarts of grape juice would we need to mix with 15/4 quarts of sparkling water.
Answer:
a), b)
Step-by-step explanation:
a) The amount of sparkling water needed is determined by simple rule of three:
b) The amount of grape juice needed is found by simple rule of three:
y = 0.25x − 4.5
y = 4x − 42
y = 4x + 18
y = 0.25x + 3
Answer:
y = 0.25x + 3
Step-by-step explanation:
solve for slope:
(6-2)/(12+4) = 1/4
solve for b:
6 = 12(1/4) + b
6 = 3 + b
b = 3
equation can also be y = 1/4x + 3
Step-by-step explanation:
let the equation be y = mx + b.
m = (6 - 2)/(12 - (-4)) = 1/4
sub (12, 6):
6 = 1/4(12) + b
b = 3
therefore, equation of the line is y = 1/4x + 3, aka option 4

b. Approximately what will the bird population be after twenty years? Round your answer to the nearest thousand.
Answer: a) The required equation is,
b) The approximately population of the birds after 20 years is 16314.
Step-by-step explanation:
a) Since, the initial population, P = 30,000
The rate of increasing, r = 3% per year,
Hence, the population of birds after T years,
Which is the required equation.
b) Now, for T = 20 years,
The population of birds,
⇒ The approximately population of the birds after 20 years is 54183.
