Answer: 18.25

Step-by-step explanation:

5.5*4=22

401.5/22=18.25

Answer:

$18.25

Step-by-step explanation:

Since area is given as A=LW, and we are given the values of the dimensions of the floor, we get:

5.5×4=22

So, the area is 22 yards, and it costs $401.5 to carpet it. Now, We simply need to divide the cost by the area to get the "cost per-square yard" as needed in the question. We get:

401÷22=18.25

So, the cost of the carpet per square yard is $18.25

The gross income will be $5,800.

It is given that per month salary of an individual is $4000 and from a side job he makes $20 per hour for 10 hours a week for 4 weeks and rent he got is $1000.

We have to calculate the gross income.

What do you mean by gross income ?

Gross income refers to the total income of a person or business from all resources.

As per the question ;

Per month salary = $4000

Earning from side job is given $20 per hour for 10 hours a week for 4 weeks.

i.e.,

= 20 × 10 × 4

= $800 for 4 week

and

the rent they receive = $1000

So ;

The gross income will be ;

= 4000 + 800 + 1000

= $5,800

Thus , the gross income will be $5,800.

a baby blue whale weigh= 2000 kg

Simple equation :

A linear equation that involves only one variable is known as a simple equation or a linear equation in one variable. For example, \(3x + 2 = 23,x = 7,2x + 6 = 3x – 4,\)etc., are simple equations.Let us assume a situation, in which you go to the market to buy mangoes in a supermarket. Your mother gave you Rs.100 and said that you can keep Rs.40 for buying chocolates and for the remaining amount, you need to buy mangoes. When you went to the market, you found out that the price of one kg of mangoes was Rs.12. So, the final question is how many mangoes you should buy, so that everyone is satisfied. Recall the concept of simple equations from previous classes and proceed. Let us assume that you have to purchase kg of mangoes, so the total amount of money that you will be spent on buying mangoes will be Rs.12x. Now, you have Rs.40 for yourself, so you have an equation:

12 x + 40 = 100

12x = 100 – 40

12x = 60

x = 60/12 = 5, This is the same equation as above. Now when you will solve this, you will get to know the value of 5kg of mangoes. It means that you can buy 5 kg mangoes and spend Rs.40 on buying chocolates

Answer:

Step-by-step explanation:

The numbers are -3 and 6

From the information given, let the number be x;

the expression is given as;

(√3x + 2) = x - 4

To determine the number, find the square of both sides, we have;

(√3x + 2) ^2 = (x - 4)^2

Find the square of both sides

3x + 2 = ( x - 4)(x + 4); difference of two squares

expand the bracket

3x + 2 = x^2 + 4x - 4x - 16

collect like terms

x^2 - 3x - 16 - 2

x^2 - 3x - 18

x^2 - 6x + 3x - 18

Factorize the expression

x( x - 6) + 3( x - 6)

(x + 3) or (x - 6)

x = -3 or x = 6

Step-by-step explanation:

    Well, we already know the amount of time it takes to make the lemonade, and we know the rate as well.

We need to find out how many pitchers you can make in an hour. If you can make one pitcher in 10 minutes, then you can make 6 pitchers in 60 minutes, AKA an hour.

So we make 6 pitchers per hour.

If we make 6 an hour, then we multiply 6 by 200 to get the number of pitchers we can make in 200 hours.

We can make 33.33 pitchers in 200 hours

The numerical length and width of the rectangular picture are 9in and 12in respectively.

Area of a rectangle is expressed as;

A = length × width

Given the data in the question;

To determine the numerical length and width of the rectangular picture, first plug the given values into the equation and solve for x.

A = length × width

108 = (2x -1)(x+7)

Expand

108 = 2x² + 14x - 1x -7

108 = 2x² + 13x -7

Reorder

2x² + 13x -7 = 108

2x² + 13x - 7 - 108 = 0

2x² + 13x - 115 = 0

Solve by grouping

(x-5)(2x+23) = 0

x-5 = 0, 2x+23 = 0

x = 5, 2x = -23

x = 5, x = -23/2

x = 5, x = -11.5

But the dimension cannot be negative, hence;

x = 5

Next, determine the numerical length and width.

Length = 2x - 1 = 2(5) - 1 = 10 - 1 = 9in

Width = x + 7 = 5 + 7 = 12in

Therefore, the numerical length and width of the rectangular picture are 9in and 12in respectively.

The equation of this linear equation is f(x) = 9/7(x - 1) + 2

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

f(−6) = −7, f(1) = 2

Start by calculating the slope (m) using

m = [f(-6) -f(1)]/[-6 - 1]

This gives

m = [-7 - 2]/[-6 - 1]

Evaluate

m = 9/7

The linear equation is then calculated as

f(x) = m(x - x1) + f(1)

So, we have

f(x) = 9/7(x - 1) + 2

Hence, the equation of this linear equation is f(x) = 9/7(x - 1) + 2

An equation that relates T to N can be written as T = 750 + 630N.

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

A function can be defined as a mathematical expression which can be used to define and represent the relationship that exist between two or more variables in a population (data set).

Since the total amount saved by using both plans (functions A and B) is represented by T, an equation that relates T to N can be written as follows:

T = A + B

Substituting the given parameters into the formula, we have;

T = (750 + 135N) + 495N

To earn $100 profit Manu should get the order of 22 glasses.

Given that, the cost price of a drinking glass=$8 and the selling price = $13.

When, in a transaction, the selling price is greater than the cost price, it means we earn a profit. The basic formula used for calculating the profit is Profit = Selling Price - Cost Price.

Let x = the number of glasses and y = profit from selling x glasses.

Now, y=(13-8)x-10

Assumed that the order is x glasses to earn a profit of $100.

(13-8)x-10=100
