There is a 15.9% increase in the price.

Step-by-step explanation:

New price = $3.65

Old price = $3.15

Difference = New price - Old price

Difference = 3.65 - 3.15 = $0.50

The positive sign indicates the increase

Percent\ increase=\frac{Differece}{Old\ value}*100\\\\Percent\ increase=\frac{0.50}{3.15}*100\\\\Percent\ increase=\frac{50}{3.15}\\\\Percent\ increase=15.87\%

Rounding off to nearest tenth

Percent increase = 15.9%

There is a 15.9% increase in the price.

The double number line shows that Kimimela
slega [8]

The completion of the table showing the different percentages of the days that Kimmimela and her foster brother fed the rabbits this year is as follows:

<h3>Rabbit Feeding Table:</h3>

Person     Time (days)    Percentage

Kimimela         350             95.9%

Foster Brother   15                4.1%

<h3>What is a percentage?</h3>

A percentage is a mathematical expression of a number or ratio as a fraction of 100.

A percentage is often denoted with the percent sign, "%."

Most importantly, a percentage shows the relative value of a variable out of the hundredth parts of the class.

For instance, this question showed that Kimimela fed her rabbits 350 out of 365 days of this year. This implies that her foster brother fed the rabbits for 15 days (365 - 350).

<h3>Data and Calculations:</h3>

Person     Time (days)    Percentage

Kimimela         350             95.9% (350/365 x 100)

Foster Brother   15                4.1% (15/365 x 100)

Total               365               100%

Thus, we can conclude that Kimimela fed the rabbits <u>96%</u> of the days.

When Legs jumps 2 times and takes 13 steps forward, he lands in the same place as when he jumps 4 times and takes 5 steps backwa
tangare [24]

Answer:

9 steps

Step-by-step explanation:

Let x be the number of jumps

and y be the number of steps

So the first case

2x+13y

Second case

4x-5y

Both cover equal distances so

2x+13y=4x-5y

\Rightarrow 2x-4x=-5y-13y

\Rightarrow 2x=18y

\Rightarrow x=9y

So, one jumps is 9 steps.

Suppose a+b = 2aa+b=2aa, plus, b, equals, 2,
Trava [24]
B-a=0.

Starting from the original equation, 
a+b=2a

We can isolate b by subtracting a from both sides:
a+b-a=2a-a
b=a

Substituting this into b-a, we have
a-a = 0
