zalisa [80]

Answer: No, they would not get the same amount.

Step-by-step explanation:

Let the number of coins be x

Eliot counts a group of coins staring with the quarters.

As we know that

1\ quarter=25\ cents

So, Number of amount Eliot counts with the quarters is given by

25\times x=25x\ cents

Similarly, His sister counts the same coins she counting the pennies .

As we know that

1\ penny=1\ cent

So, Total amount his sister counts with  the pennies is given by

1\times x=x\ cents

But we can see that

25x\ cents\neq x\ cents

Hence, No, they would not get the same amount.

What are simultaneous equations​
Masja [62]

Answer:

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.

Nikki’s Pizza Joint charges $14 for a super-duper cheese pizza and $2 for each extra topping. How many toppings can you order fo
stiv31 [10]

Answer:

5 toppings

Step-by-step explanation:

The formula is y=2x+14 with x being the number of toppings and y the total price.

Plug in 25 as y to see how much x would be at that price.

25=2x+14

11=2x

x=5.5

You can't get half of a topping so you would have to round down to 5 toppings.

The dot plot shows the ages of students, in years, on a basketball team.Each dot represents 1 student.Age (yr)nd the mean (round
Sever21 [200]

As given by the question

There are given that the dot plots that show the ages of students.

Now,

As obtained from the dot plot:

x=11,\text{ 11, 11, 12, 12, 12, 13, 13, 13, 13, 14, 14, 15, 15}

Now,

The mean of the given data is:

\text{Mean}=\frac{Addition\text{ of the total given data}}{\text{Total number of data}}

So,

\begin{gathered} \text{Mean}=\frac{Addition\text{ of the total given data}}{\text{Total number of data}} \\ \text{Mean}=\frac{11+11+11+12+12+12+13+13+13+13+14+14+15+15}{14} \end{gathered}

Then,

\begin{gathered} \text{Mean}=\frac{179}{14} \\ \text{Mean}=12.8\text{ years} \end{gathered}

And,

The mode of the given data is:

The mode is defined for the most frequently occurring value

So,

\begin{gathered} \text{Mode}=\text{most frequently occurring value} \\ \text{Mode}=13 \end{gathered}

Hence, the value of the mean is 12.8 and the mode is 13.
