please answer these questions my mom is really mad at me because I have a 73 in math and I need to higher my grade pls help

Answer:

143cm

Step-by-step explanation:

Area=2(l+b)

Substitute the values for the variables.

66=2(l+22/5)

66=2xl+2x22

5

66=2l+44

5

Cross multiply

66x5=2l+44

330=2l+44

Collect like terms

-2l = 44-330

-2l = -286

-2l = -286

-2 -2

l=143

The missing length is 143m.

Answer:

Second option

Step-by-step explanation:

Given the following question:

[tex]8(6n+6)[/tex]

To find the answer we have to simplify the following expression and then simplify the options in till we have a equivalent answer.

[tex]8(6n+6)[/tex]
[tex]8\times(6n+6)[/tex]
[tex]8\times6n=48n[/tex]
[tex]8\times6=48[/tex]
[tex]48n+48[/tex]

Now one of these options after being simplified will be equal 48n + 48.

[tex]48+6[/tex]
Already simplified

First option isn't equivalent to the given expression.

[tex]8(n+5n+6)[/tex]
[tex]n+5n=6n[/tex]
[tex]8\times(6n+6)[/tex]
[tex]8\times6n=48n[/tex]
[tex]6\times8=48[/tex]
[tex]48n+48[/tex]

Second option is equivalent to the given expression.

Hope this helps.

Answer:

  see below for slopes and lengths

  scalene quadrilateral

Step-by-step explanation:

When calculations are repetitive, it is reasonable to let a spreadsheet do them.

 FG: slope: -4/5, length: √41 ≈ 6.40

  GH: slope: -5, length: √26 ≈ 5.10

  HI: slope: -1, length: 3√2 ≈ 4.24

  IF: slope: 4, length: √17 ≈ 4.12

All of the segments are different lengths, and none of them are parallel or perpendicular. The figure is a scalene quadrilateral.

__

As you know, the slope is calculated from ...

  m = (y2 -y1)/(x2 -x1)

and the length is calculated from ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

_____

In the attached spreadsheet, the slope and length are calculated from the point below. That is, the values on the line for F are for segment FG.

Step-by-step explanation:

Total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.

The rent of the apartment is $650 per month. The rent of the two months (first and last) is,

[tex]M=2\times650\\M=1300[/tex]

This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,

[tex]P=\dfrac{1300}{3}\\P=433.33[/tex]

They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. Therefore,

[tex]P=640-433P=206.67[/tex]

Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,

[tex]SD=206.67\times3\\SD=620.01[/tex]

Hence, total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

Answer:

540x+680y<=20000

Step-by-step explanation:

x will be the number of laptops. Since they are $540 each, 540x is the amount spent on laptops, depending on how many (x) are purchased.

y will be the number if desktops. Since they are $680 each, 680y is the amount spent on desktops, depending on how many (y) are purchased.

Adding all the money spent on laptops and desktops, we get

540x + 680y. This amount must be less than the $20000. It can be exactly $20000 also. But it cannot be more than $20000.

540x+680y<=20000

Answer:

1540 square in-17.4π in

Step-by-step explanation:

The box's area is 1540 square inches, and the volume of a sphere is 4πr. So we do 4*π*r, which is 4π*4.35, and simplify it to 17.4π. Then we subtract that from the 1540 square in to get the final answer of 1540-17.4π

Reference: π is approximately 3.1415926

The correct answer is:  " [tex]j^(^-^4^)[/tex] "; or; write as:  " [tex]j^{-4}[/tex] ".

_______

Step-by-step explanation:

Given:  " [tex]\frac{j}{j^4* j}[/tex] " ;  assuming:  " [tex]j\neq 0[/tex] " ;
_______
We are asked to express the correct answer (i.e. simplying the expression in a specific manner):  "as a single term, without a denominator."  
_______
  As such, we can cancel out the "j" in the numerator, to "1" ; and cancel out the "j" in the denominator; to "1" ; since:  " j ÷ j = 1 " ;  

→  And we can rewrite the expression as:
   "  [tex]\frac{1}{j^{4}* 1 }[/tex] " ;

         =  " [tex]\frac{1}{j^4}[/tex] " ;
_______
Now, note the following property of exponents:
_______
   " [tex]x[/tex]⁽⁻ⁿ⁾ =  [tex]\frac{1}{x^n}[/tex] " ;  {" [tex]x\neq 0[/tex] "} ;
_______
Likewise:
  " [tex]\frac{1}{j^4}[/tex] ⇔ " [tex]j^(^-^4^)[/tex] " ; which is the correct answer:  

  →  " [tex]\frac{1}{j^4} = j^{-4}[/tex] " .

Determine whether24:30  and 3:7/2 are equivalent therefore making it False

If g is a vertical translation of f, the number of  units and in the direction f translated to form g is,  7 units and downward  direction

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

Two functions,

f(x) = x + 4

g(x) = x – 3

the difference in values of function f(x) & g(x)

f(x) -  g(x) =  x + 4 - ( x – 3 )

                =  x + 4 - x +3

                =    7

So, if we subtract 7 from the function f(x)

⇒    f(x) - 7

⇒    x + 4 - 7

⇒    x  - 3

So, vertical translation required is  value 7 and in downward direction
