Answer:
The constant of proportionality is 1/2
Step-by-step explanation:
The plants grow 1/2 in per week
At the second concert, there were 217% more people than in the first concert.
<h3>What are percentages?</h3>
Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. The sign used to represent percentages is %.
<h3>What is the comparison between the two concerts?</h3>
Number of people who attended the second concert compared to the first concert = (949/299) - 1 x 100 = 217%

Answer:
<h3>5ths</h3>
Step-by-step explanation:
Given that:
- Price of whole pizza (A) = 5 × 3 = $15
- Price of whole pizza (B) = 4.50 × 5 = $22.50
They make 8 whole pizzas.
Therefore
- Thirds (A) = 15 × 8 = $120
- Fifths (B) = 22.50 × 8 = $180
They'll make more money if they slice it into fifths.
180 - 120 = $60
Because if they slice it into thirds, total profit will be $60 less

Answer:
Step-by-step explanation:
Let's call hens h and ducks d. The first algebraic equation says that 6 hens (6h) plus (+) 1 duck (1d) cost (=) 40.
The second algebraic equations says that 4 hens (4h) plus (+) 3 ducks (3d) cost (=) 36.
The system is
6h + 1d = 40
4h + 3d = 36
The best way to go about this is to solve it by substitution since we have a 1d in the first equation. We will solve that equation for d since that makes the most sense algebraically. Doing that,
1d = 40 - 6h.
Now that we know what d equals, we can sub it into the second equation where we see a d. In order,
4h + 3d = 36 becomes
4h + 3(40 - 6h) = 36 and then simplify. By substituting into the second equation we eliminated one of the variables. You can only have 1 unknown in a single equation, and now we do!
4h + 120 - 18h = 36 and
-14h = -84 so
h = 6.
That means that each hen costs $6. Since the cost of a duck is found in the bold print equation above, we will sub in a 6 for h to solve for d:
1d = 40 - 6(6) and
d = 40 - 36 so
d = 4.
That means that each duck costs $4.
