3 + √97/2 , -3 ±√97/2 are the dimensions of rectangle .

What is rectangle?

let width = x

length = x + 3

area = 22

 area of rectangle =  l * w

           22 =  x * ( x + 3 )

          22 = x² + 3x

       x² + 3x - 22 = 0

    x = -3 ± √3² - 4 .1 (-22)/2.1

   x = -3 ± √9 + 88/2

    x = -3 ±√97/2

width =  -3 ±√97/2

length =  x + 3  =  -3 +√97/2 + 3 = 3 + √97/2

A solution to a system of linear equations in two variables is an ordered pair that makes BOTH equations true.

When is the system of equations is said to be consistent?

If there is at least one combination of values for the unknowns that satisfies each equation in the system—that is, makes each equation hold true as an identity—then a system of equations, whether linear or nonlinear, is said to be consistent.

When is the system of equations is said to be non-consistent?

If there isn't a set of values for the unknowns that solves every equation, then the system of equations is said to be inconsistent.

Ex: Consider a system of linear equations:

x+3y=6                    

x=-3y+6                       …..(1)

2x+8y= -12                  …..(2)

Substitute equation (1) in (2)

2(-3y+6)+8y=-12

-6y+12+8y=-12

           2y=-24

            y=-12              ….(3)

Substitute equation (3) in (1)

x+3(-12)=6

x-36=6

x=42

Here, the order pair (x,y)=(42,-12) is the solution of the given linear equations and satisfy equations (1) and (2)

> 42+3(-12) = 42-36             .....From (1)

The 100th term of the arithmetic sequence is 203.

Let the first term of the arithmetic sequence be a and the common difference be d.

The general term of the sequence is given by

[tex]T_{n} = a + (n-1)d[/tex]

It is given that the 6th term is 15, we have :
[tex]T_{6} = a +5d[/tex]  

a + 5d = 15......equation(1)

It is given that the 9th term is three times the 2nd term, we have :

[tex]T_{9} = 3*T_{2} \\a + 8d = 3(a +d)\\a + 8d = 3a +3d\\a -3a = 3d -8d = -5d\\-2a = -5d\\2a = 5d\\a = \frac{5d}{2}[/tex]

Putting this value in equation(1)

[tex]\frac{5d}{2} + 5d = 15 \\\\5d + 10d = 30\\15d= 30\\d = \frac{30}{15} = 2[/tex]

a = 5*2/2 = 5

Hence, the first term is 5 and the common difference is 2.

Now, evaluating the 100th term of the sequence, we have :

[tex]T_{n} = a +(n-1)d\\T_{100} = a +99d\\T_{100} = 5 +99*2 = 5 +198 = 203[/tex]

Hence, the 100th term of the arithmetic sequence is 203.

We have the next information

A submarine Is at a depth of 350 feet below sea level means -350

First, it goes down 150 feet. means -150

Next, it goes up 132 feet. means +132

Then, it goes down 179 feet. means -179

Finally, it goes down 145 feet means -145

then we have the next operations

-350+(-150)+132+(-179)+(-145)=-692

The sing minus means that It is below the sea level

therefore the correct choice is

A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.

The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

|x| = x, x ≥ 0.

|x| = -x, x < 0.

It measures the distance of a point x to the origin, thus, |-2| = |2| = 0, and has vertex(turning point) at (0,0). Then the range is from the y-coordinate of the vertex to positive infinity.

WE have given as s=l-r l

When we add a positive or negative number in between the lines then; it is;

|-r| goes through = -r = -s

|-r| goes through = r = s

The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".

Let's see the facts:

%Earns= 13% commission/week

Last week sold = $7,500

In order to obtain the last week earns in commission we need to multiply % rate of commission by the last week sold as shown as follows:

$Earns = 0.13 (decimal form)*$7,500

Earns = $975

Last week, he made $975 in commission.

If he averages that same amount each week, he should make $975* 52(number of weeks per year) = $50,700/year

There 6 quarters and 24 nickels of each coins that John Carlo has.

There are 5 cents in a nickel and 25 cents in a quarter. Let us represent the number of quarters as x so that the number of nickels that John Carlo has will be 4x.

Thus, 4x(5 cents) + x(25 cents) = 270 cents

20x cents + 25x cents = 270 cents

45x cents = 270 cents

divide through by 45

x = 270/45

x = 6

and thus there are 4(6) = 24 nickels.

Therefore, John Carlo has 6 quarters and 24 nickels each of coins.

The highest possible price that a customer could have paid for their meal that evening exists $ 757. Since this is a fundraiser, $ 1 exists probably a very small amount and $757 would be considered a very generous donation for a meal.

When determining the mean (average) of a group of values, we add up the values in the group and divide that total by the number of values in the group. As a result, the average of the set's values divided by the total number of values is equal to the set's values' sum.

Let n represent how many people were in the store that evening. Thus, a total of 56n was paid that evening by all customers. The bill for the last customer's meal was $70.00. There were (n-1) customers who had already paid a total of (56n-70) dollars before this one arrived. The average cost per customer at that time was $55 dollars.

From the above information, we get

[tex]$\frac{56 n-70}{n-1} &=55 \\[/tex]

simplifying the above equation, we get

56n - 70 = 55(n - 1)

56n - 70 = 55n - 55

n = 15

Since n = 15, it follows that there were 15 customers that evening, and the total amount paid by all customers stood therefore 56 n = 56(15) = 840 dollars.

To estimate the highest possible price that a customer could have paid for their meal that evening, we will assume that 13 of the customers paid the lowest possible price of $ 1. Then the remaining customer would have paid 840 - 13 × 1 - 70 = 757 dollars.

Therefore, the highest possible price that a customer could have paid for their meal that evening exists $ 757.

Since this is a fundraiser, $ 1 exists probably a very small amount and $757 would be considered a very generous donation for a meal.

Ratio of the length of a tile in model to length of actual tile is 1/9 and Ratio of Area of tile to area of actual tile is 1/ 81

Given,

Length of each tiles = 2/3 in

Width of each tiles = 1/2 in

The actual tiles have length = 1/2 ft = 6 in {1 foot = 12 inch }

Width of actual tiles = 3/8 ft = 4.5 in

Ratio of length of tile in the model to the length of an actual tile =

length of tile / length of an actual tile

= [tex]\frac{2/3}{6} = \frac{1}{9}[/tex]

Area of tiles = area of rectangle = length × width

= 2/3 × 1/2

= 1/3 in²

Area of actual tile = 6 × 4.5 = 27 in²

Ratio of the area of a tile in the model to the area of an actual tile =

Area of tile / area of actual tiles

= [tex]\frac{1/3}{27} = \frac{1}{81}[/tex]

Another way of finding ratio is by Dilation ,

The vertex form of the expression is y = (x-4)²-1

What is vertex form?

In this little tutorial, we'll look at how to change a standard form into a vertex form and vice versa. A parabola's equation can be shown in various ways, including standard form, vertex form, and intercept form. Any of these forms can be changed into either of the other two depending on the situation. We will discover how to convert in this article.

The vertex form is y = (x-h)² + k

The only term with x with 2hx from the vertex form and 8x in order to form a standard form.
