can y'all pleas help me with this

Answer: 63/50 meters^2 or in mixed number 1 13/50 meters^2

Step-by-step explanation:

area= length x width

length = 4 1/5= 21/5 . multiply the whole number with the denominator 4x5= 20 add 20 with the numerator 20+1=22

width = 3/10

21/5 x 3/10 ( multiply the denominators together)

21x3 / 5x10

= 63/50 meters^2 or in a mixed number 1 13/50 meters^2

(by the way I'm guessing you meant 3/10 and not 3/q0)

Answer:

The equation is sale price=p and the original price is $41.09.

                              .70

Step-by-step explanation:

sale price= (1-.30)p      

sale price=.70p

.70              .70

sale price=p                  

.70

28.76=p

.70

$41.09=p

Answer:

C. P(x) = -0.6x3 + 300x^2 – 700x + 600

Step-by-step explanation:

The profit function is P(x) = -0.6x³ + 300x² - 700x + 600.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given,

Cost function, C(x) = 500x² + 400x

Revenue function, R(x) = -0.6x³ + 800x² - 300x + 600

Profit is the difference between the revenue and the cost.

Profit function is therefore the difference of revenue function and the cost function.

P(x) = R(x) - C(x)

P(x) = (-0.6x³ + 800x² - 300x + 600) - (500x² + 400x)

      = -0.6x³ + 800x² - 300x + 600 - 500x² - 400x

      = (-0.6x³) + (800x² - 500x²) + ( - 300x - 400x) + 600

      = -0.6x³ + 300x² - 700x + 600

Hence the profit function of the granola bar company is P(x) = -0.6x³ + 300x² - 700x + 600.

Complete Question

The complete question is shown on the first uploaded image  

Answer:

a

[tex]P(X < 65) =  0.003467[/tex]

b

[tex]P(86 <  X <  110 )= 0.63928 [/tex]

c

[tex]P(X > 120 ) =0.062024[/tex]

Step-by-step explanation:

From the question we are told that

 The  mean is  [tex]\mu  =  \$ 100[/tex]

 The  standard deviation is  [tex]\sigma  =  \$ 13[/tex]

 Generally the probability that the  monthly utility bills is less than  $65  is  mathematically represented as

     [tex]P(X < 65) =  P(\frac{X  -  \mu }{\sigma }  < \frac{65  -  100 }{13 }   )[/tex]

Generally

  [tex]\frac{X  -  \mu }{\sigma } =  Z (The\ standardized \ value \ of\  X )[/tex]

So

 [tex]P(X < 65) =  P(Z < -2.70  )[/tex]

From the z-table

    [tex]P(Z < -2.70  ) =  0.003467[/tex]

So  

   [tex]P(X < 65) =  0.003467[/tex]

Generally the  probability that a randomly selected utility bill is between $86​ and $​110 is mathematically represented as

 [tex]P(86 <  X<  110 )=  P( \frac{86 -100}{ 13} <  \frac{X - \mu}{\sigma } < \frac{86 -100}{ 13}    )[/tex]

=>  [tex]P(86 <  X <  110 )=  P( \frac{86 -100}{ 13} < Z < \frac{110 -100}{ 13} )[/tex]      

=>    [tex]P(86 <  X <  110 )=  P(-1.08 < Z < 0.77 )[/tex]      

=>    [tex]P(86 <  X <  110 )= P(Z < 0.77 ) -  P(Z < -1.08 ) [/tex]    

From the z-table

    [tex]P(Z < 0.77 ) = 0.77935[/tex]

and  

   [tex]P(Z < -1.08 ) =  0.14007[/tex]

So

     [tex]P(86 <  X <  110 )= 0.77935  -  0.14007 [/tex]    

=>   [tex]P(86 <  X <  110 )= 0.63928 [/tex]    

 Generally the probability that the  monthly utility bills is  more than $120  is mathematically represented as

         [tex]P(X >120 ) =  P(\frac{X  -  \mu }{\sigma }  > \frac{120  -  100 }{13 })[/tex]

=>   [tex]P(X > 120 ) =  P(Z > 1.538   )[/tex]

From the z-table

    [tex]P(Z > 1.54  ) =  0.062024[/tex]

So  

   [tex]P(X > 120 ) =0.062024[/tex]

Answer:

(5x - 1)(5x - 1) = 25x² - 10x + 1

Step-by-step explanation:

Let us solve the question step by step

We need to find the product of (5x - 1) and (5x - 1)

∵ 5 × 5 = 25

∵ x × x = [tex]x^{1+1}[/tex] ⇒ multiply same base means add their powers

∴ x × x = x²

∴ 5x × 5x = 25x²

∵ 5x × -1 = (5 × -1)x

∴ 5x × -1 = -5x

∵ -1 × 5x = (-1 × 5)x

∴ -1 × 5x = -5x

∵ -1 × -1 ⇒ (-)(-) = (+)

∴ -1 × -1 = 1

∵ (5x - 1)(5x - 1) = 25x² + -5x + -5x + 1

∵ -5x and -5x are like term, then add their coefficients

∵ -5x + -5x = (-5 + -5)x

∴ -5x + -5x = -10x

∴ (5x - 1)(5x - 1) = 25x² + -10x + 1

∵ (+)(-) = (-)

∴ (5x - 1)(5x - 1) = 25x² - 10x + 1

Answer:

You have 2 values for g(x) and they are set equal to each other. Which means.....

-x-1 = 3

-x = 3+1

-x = 4

x = 4/-1

x = -4

Answer:

No, because one x-value corresponds to two different y-values ⇒ D

Step-by-step explanation:

The relation of x and y can be a function if every x has only one value of y (x not repeated)

Examples:

Let us check the given table

∵ At x = 2, y = 1

∵ At x = 3, y = 4

∵ At x = 4, y = 4

∵ At x = 5, y = 2

∵ At x = 5, y = 5

∵ x = 5 has two values of y 2 and 5

→ That means x is repeated

∴ Not every x has only one value of y

∴ The table does not represent a function

∴ The right answer is D

Answer:

C= 25.13ft

Step-by-step explanation:

To find the circumference use the formula C=2 * PI * R

we know that the diameter is 8 which means that the radius is half that amount therefore R=4

Now plug those numbers into the formula

C=2(pi)(4)

= 8(pi)
