His parakeet is 134 milimeters tall.
Answer:
20%
0.5
Step-by-step explanation:
There are 20 margins, so you have to count how many are 6.0 or higher. There are 4 margins that fit this so you divide the 4 margins by 20, then multiply the quotient by 100. That's how you get 20%.
The most common time was 0.5.
Answer:
36
Step-by-step explanation:
Divide 108 by 3 to get your answer, since the denomintors are the same.
103/3 = 36
Answer:
y = 6 when x = 18
Step-by-step explanation:
The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.
We know y = 3 when x = 9: 3 = k(9)
This yields k = 3/9, or k = 1/3
Then the formula is y = (1/3)x
and when x = 18, y = (1/3)(18) = 6
y = 6 when x = 18
Answer:
12.5 hrs
Step-by-step explanation:
The rate at which the mower burns gas is 0.4 gallon / hr.
The greatest volume of gas that the tank can hold is 5 gallons.
If x is the number of hours the mower runs, then:
(0.4 gal/hr)x ≤ 15 gal, or x ≤ (15 gal) / (0.4 gal/hr), or x ≤ 12.5 hrs
