Jenny tiene 50 fichas cuadradas. Ordena las fichas en una matriz rectangular de 4 hileras. ¿Cuántas fichas sobrarán?​

Answers

Answer 1

If Jenny has 50 square tiles and arranges them in a rectangular array with 4 rows, then she would have a total of 48 tiles, with 2 tiles left over.

How to find the number of tiles

If Jenny arranges the tiles in a rectangular array with 4 rows, this means each row will have 50/4 = 12.5 tiles. However, since we cannot have half a tile, we need to round down to the nearest whole number, which is 12.

Therefore, each row will have 12 tiles, and the total number of tiles used will be 4 x 12 = 48. To find out how many tiles are left over, we need to subtract the total number of tiles used from the original number of tiles: 50 - 48 = 2. So, there will be 2 tiles left over.

Jen has driven 15 miles on her way to the mall. this distance is 3/5 of the total distance. if d represents the total distance in miles, which equation can be used to find d

Answers

This can be resolved with d = 25 miles by multiplying equation both sides by

Which equation can be used to find d?

If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:

15 = (3/5) * d

To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:

15 * (5/3) = d

Simplifying the expression on the left side, we get:

25 = d

Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.

In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:

15 = (3/5) * d

Which can be solved for d by multiplying both sides by 5/3, giving:

d = 25 miles

In conclusion, assuming that Jen has driven 15 miles, which is 3/5 of the entire trip, the equation that can be used to determine the whole distance d is:

15 = (3/5) * d

What is a Variable?

A variable is anything that may be altered in the context of an experiment or mathematical idea. A single symbol is frequently used to denote a variable. Generic symbols for variables are the letters x, y, and z. Variables are qualities with a wide range of values that may be investigated. These include characteristics like height, age, wealth, place of birth, academic standing, and kind of residence, to mention a few. The two primary groups of variables can be separated using numerical and categorical approaches.

Let's define the variables first:

Let's call John's sales of notebooks "n" the quantity.

Each notebook costs $1.50, hence the whole profit from notebook sales is $1.50.

John earned a total of $92.50, according to the issue, thus we can create the following equation:

$40.00 + 1.5n = $92.50

Now that "n" is solved, we can:

$1.5n = $92.50 - $40.00

$1.5n = $52.50 \sn = 35

John consequently sold 35 notepads.

The solution to the system of equations is x = 6 and y = 2.

The system of equations can also be solved using the elimination method.

what is the elimination method?

We are aware that a system of linear equations is a collection of two or more equations with at least two unknown variables. Finding the answers to the unknown variables in a system of equations is the process of solving a linear equation. There are numerous ways to identify the answers to the unknown variables. These include the cross-multiplication method, elimination method, substitution method, and graphic method.

from the question:

A system of equations can be solved in a variety of methods, including substitution, elimination, and matrices. I'll apply the substitution technique here:

x = 8 - y is the result of the first equation.

We can solve for y by substituting this expression for x in the second equation:

-x + 4y = 2

-(8 - y) + 4y = 2 (substituting x = 8 - y)

-8 + 5y = 2 (simplifying)

5y = 10 (adding 8 to both sides)

y = 2 (dividing by 5)

Knowing y, we can now use this quantity to solve one of the initial equations to determine x:

x + y = 8

x + 2 = 8 (substituting y = 2)

x = 6 (subtracting 2 from both sides)

Hence, x = 6 and y = 2 are the answers to the system of equations.

Answers

The linear equation that gives the rule for the given table  x 0 1 2 3 y 0 2 4 6 is y = 2x.

What is linear equation?

A linear equation is an equation of a straight line in the form of y = mx + b, where m represents the slope of the line, and b represents the y-intercept.

The slope of the linear equation can be found by calculating the change in y over the change in x:

slope=(y2 - y1) / (x2 - x1)

Taking (x1,y1) = (0,0) and (x2,y2) = (3,6),

slope=(6 - 0) / (3 - 0)

        = 2

So slope of the linear equation is 2.

Next, we can use the point-slope form of the linear equation to find the equation of the line:

y - y1 = m(x - x1)

Taking (x1,y1) = (0,0) and m = 2,

y - 0 = 2(x - 0)

For what value of k will V= x+ k/x have a relative minimum at x = 3?​

Answers

The value of k will make V = x + k/x have a relative minimum at x = 3 is k = 9

What is a relative minimum?

A relative minimum of a function is the minimum value of the function in a particular interval.

Since we have the function  V = x + k/x. We desire to find the value of k that will make V = x + k/x have a relative minimum at x = 3

So, to find the relative minimum of V, we differentiate with respect to x and equate to zero.

So, V = x + k/x

dV/dx = d(x + k/x)/dx

= dx/dx + kd(1/x)/dx

= 1 - k/x²

Equating dV/dx to zero, we have that

dV/dx = 0

⇒ 1 - k/x² = 0

1 = k/x²

k = x²

For a relative minimum at x = 3, substitute x = 3 into the equation. So, we have that

k = x²

= 3²

Answer:

1.3

Step-by-step explanation:

To find the average number of siblings for the group, we need to calculate the total number of siblings and divide by the total number of children.

Out of the 15 children:

5 are only children, so they have 0 siblings each.

3 have 1 sibling each, so there are 3 * 1 = 3 siblings in total.

4 have 2 siblings each, so there are 4 * 2 = 8 siblings in total.

3 have 3 siblings each, so there are 3 * 3 = 9 siblings in total.

The total number of siblings is 0 + 3 + 8 + 9 = 20.

I = (9,000·10·15) / 100

I = 1,350,000 / 100

I = $13,500

Answer:

Step-by-step explanation:

Perimeter add all the sides.

so let's walk around and combine like terms:

starting on the bottom moving to the left.

3x^2 + x^2= 4x^2 (there are no other squared terms)

back to the bottom moving left again:

-11x-3x+3x+x = -10x (-3x + 3x =0)

so -11x + x = -10x

now add all of the constants

-1 + 2 = 1

so your answer is

4x^2 -10x + 1
