Answer:

They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,

Step-by-step explanation:

Width : x

Length : x-44 (from the 1st sentence of question)

So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,

2(x)+2(x-44)=150150

2x+2x-88=150150

4x-88= 150150

4x= 150150+88=150238

4x=150238

x= 150238÷4

=37559.5

Answer:

The width is 8 meters and the length is 3(8)-2=22 meters. Hope this helps (owo)/ brainlist please.

Step-by-step explanation:

Let x= the width

then 3x-2= length (because the length is 2 meters less than 3 times the width)

P=2l+2w

60=2(lenght)+2(width)

60=2(3x-2)+2x      

60=6x-4+2x    Distribute

60=8x-4          Combine like terms

64=8x             Divide both sides by 8

8=x

Step-by-step explanation:

Rate of Change

The average velocity is defined as the rate of change of the distance with respect to time. The table shows the distances of an object as a function of time.

It's required to find the average velocity between 8 s and 20 s.

The rate of change can be approximated as the slope between two points. We take from the table the points (8,32) and (20,10) and calculate the slope.

The slope can be calculated with the equation:

[tex]\displaystyle v=\frac{d_2-d_1}{t_2-t_1}[/tex]

[tex]\displaystyle v=\frac{10-32}{20-8}=\frac{-22}{12}[/tex]

Simplifying:

[tex]\displaystyle v=-\frac{11}{6}[/tex]

Answer:

400 gallons are 1100 / 63 of 126 L.

Step-by-step explanation:

Given

1 Gallon = 4.5 L

To determine

What fraction of 400 gallons is 180 L

as

1 Gallon = 4.5 L

so

400 Gallons = 400 × 4.5

                     = 1800 L

In order to determine the fraction of 400 gallons is 180 L, just divide 1800 by 180, so

Fraction = 2200 ÷ 126

              = 1100 ÷ 63

Therefore, 400 gallons are 1100 / 63 of 126 L.

Answer:

x=35, y=35

Step-by-step explanation:

To be honest, you don't even have to do any maths to figure this one out if you know the theory.

Basically, any angles standing on the same arc (like x and y) are equal. So we know x=y, and the first option(x=35,y=35) is the only option where x is the same as y.

Answer:

Value after one year = Rs 9000

Step-by-step explanation:

The depreciation refers to a reduction in value of the asset (sofa-set) due to usage and other factors. The depreciation charge at the rate of 10% means that the reduction in value at 10% of cost per year.

Depreciation per year = 10000 * 0.1 = Rs 1000

So, the value after one year will be,

Value after one year = 10000 - 1000

Value after one year = Rs 9000

Answer:

Kendall makes 120$ profit by selling necklaces.

Step-by-step explanation:

To show how much it costs to make all the necklaces in total multiply 2 x 40 to get 80$. To show much much money she gets for the necklaces multiply 5 x 40 to get 200$.  To show how much profit she makes subtract 80$ from 200$ to get 120$.

Answer:

(d)- $26.74

Step-by-step explanation:

John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99. How much money does John spend on donuts throughout the week?

a) $23.24

b) $19.64

c) $29.14

d) $26.74

The total money spends on donuts throughout the week is $26.74 option (d) is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

The missing options are:

We have:

John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99.

Let the total number of working days in a week be 5

Total money spend on employees = 5×2.75 = $13.75

Total money spend on donuts throughout the week = 13.75 + 12.99

= $26.74

Thus, the total money spends on donuts throughout the week is $26.74 option (d) is correct.

Step-by-step explanation:

Step-by-step explanation:

Sale price

= Marked down by 10% from selling price

= 90% of selling price

= 0.9 * $600

= $540.

Sale price - Cost price

= $540 - $450 = $90.

The markup from cost to sale is $90.

The markup from cost to sale price will be $90.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The selling cost of a thing is $600. It is discounted by 10%, however, this deal cost is as yet increased from the expense of $450.

The sale price is given as,

Sale price = 0.90 x $600

Sale price = $540

The markup cost to sale will be given as,

⇒ $540 - $450

⇒ $90

The markup from cost to sale price will be $90.

Answer:

z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]

Step-by-step explanation:

We are given:

[tex]x=2y-5\: and\: z=16y^3[/tex]

We need to find z in terms of x

First we can find value of y from x =2y-5

[tex]x =2y-5\\x+5 = 2y\\y=\frac{x+5}{2}[/tex]

Now, we can put value of y in [tex]z=16y^3[/tex] to find z in terms of x

[tex]z=16y^3\\Put\:y=\frac{x+5}{2}\\z=16(\frac {x+5}{2})^3[/tex]

So, z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]

21 seconds = -294 meters

=> 1 second = -294/21 = -14 meters

Hence the average change is -14 meters per second.

The average change  in the submarines depth  is -14 meters per second.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

A submarine was at the surface of the water.

21 seconds later, it was at a depth of 294 meters.

We have to find the average change in the submarines depth each second.

According to given question we have

21 seconds = -294 meters

=> 1 second = -294/21 = -14 meters

Hence ,the average change  in the submarines depth  is -14 meters per second.

Answer:

The equation of the line in slope-intercept form is:

[tex]y = x + 4[/tex]

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  m is the slope  and b is the y-intercept

Given the equation

Determining the slope between (1, 5) and (2, 6)

(x₁, y₁) = (1, 5)

(x₂, y₂) = (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [5 - 4] / [1 - 0]

                  = 1 / 1  

                   = 1

Thus, the slope of the line = m = 1

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 4

Thus, the y-intercept b = 4

now substituting b = 4 and m = 1 in the slope-intercept form

[tex]y = mx + b[/tex]

[tex]y = (1)x + 4[/tex]

[tex]y = x + 4[/tex]

Therefore, the equation of the line in slope-intercept form is:

[tex]y = x + 4[/tex]
