PLEASE HELP ASAP 10+ PTS!!

Step-by-step explanation:

its -3x-6+(-1)? if yes please let me know. thanks

Answer:

x = -10

Step-by-step explanation:

First combine like terms; -6 + -1 = -7, since + a negative is just minus.  

(So -6 - 1.)  Rewrite the equation as -3x - 7.  Divide x from both sides, so

-3 - 7 = x.  Simplify into x = -10.  

I'm so sorry if I'm wrong, I hope this helps though!

what are the options please ?

Answer:

a) 513775.5 m^3  ≈ 51.38 * 10^4 m^3

b)  256887.75 m^3 ≈ 25.69 * 10^4 m^3

Step-by-step explanation:

Given data :

Depth of pond = 2m

flow in the stream = 20 cfs = 4.8931 * 10^4 m^3/day

settling rate = 0.2 m/day

rate constant ( k )= 0.2 / 2 = 0.1 / day

steady-state removal of the solids required = 65%

A) determine size of a single CSTR to achieve 65%

First determine the time required to achieve this using the relation below

C = [tex]c_{o} e^{-kt}[/tex]

∴ t = [tex]\frac{-1}{k}* ln( 1 - 0.65 )[/tex]

     = ( -1 / 0.1 ) * (- 1.05 ) = 10.5 day

The size of a single CSTR required = ( 4.8931*10^4 ) * (10.5 ) = 513775.5 m^3

B) determine the sizes of a pair of identical CSTRs in series needed to achieve the desired removal

sizes of a pair = 513775.5 / 2 = 256887.75 m^3

Answer:

[tex](a)\ m+ 2.1 > n + 2.1[/tex]

[tex](b).\ m - (-4) > n - (-4)[/tex]

[tex](c)\ 9 +m> 6 + n[/tex]

Step-by-step explanation:

Given

[tex]m > n[/tex]

Required

Select true inequalities

[tex](a)\ m+ 2.1 > n + 2.1[/tex]

Subtract 2.1 from both sides

[tex]m > n[/tex]

This is true

[tex](b).\ m - (-4) > n - (-4)[/tex]

Open brackets

[tex]m + 4 > n + 4[/tex]

Subtract 4 from both sides

[tex]m > n[/tex]

[tex](c)\ 9 +m> 6 + n[/tex]

[tex]m> -9+6 + n[/tex]

[tex]m> n-3[/tex]

This is also true

27/30+25/30 =

52/30 = 1 22/30 =1 11/15

Answer: 26/15

Step-by-step explanation:

1. First find the common denominator, which is 30

2. Add them

3. Simplify (common factor of 2)

[tex]\frac{27}{30} + \frac{25}{30} \\\\\frac{52}{30} \\\\\\\frac{26}{15}[/tex]

Answer:

n ≈ 8.54

Step-by-step explanation:

Reference angle = 30°

Opposite side = n

Adjacent side = 14.8

Apply TOA, which is:

Tan 30 = opp/adj

Tan 30 = n/14.8

Multiply both sides by 14.8

14.8×tan 30 = n

8.54478398 = n

n ≈ 8.54 units (to 2 dp)

Answer: [tex]\dfrac{11}{36}[/tex]

Step-by-step explanation:

Total outcomes for rolling a pair of six-sided dice n(S)= 6 x 6 =36

Let A be the event that the first die is one and B be the event that the sum of the dice is eight.

A = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)}

P(A)= [tex]=\dfrac{n(A)}{n(S)}=\dfrac{6}{36}[/tex]

B= {(2,6), (6,2), (3,5), (5, 3), (4,4)}

P(B)= [tex]=\dfrac{n(B)}{n(S)}=\dfrac{5}{36}[/tex]

A ∩ B = Ф

P(A ∩ B)=0

P(A or B)= P(A)+P(B)+P(A∩ B)

[tex]=\dfrac{6}{36}+\dfrac{5}{36}+0\\=\dfrac{11}{36}[/tex]

Hence, P(A or B) = [tex]\dfrac{11}{36}[/tex]

Answer:

18000000

Step-by-step explanation:

2000 x 9000 = 18000000

9 x 2 = 18

there are 3 0's on the 2 and 3 0's on the 9 so we are going to add them together.

000 + 000 = 000000

put the two answer together and they equal...

18000000

Step-by-step explanation:

1 2 ⋅ −7 = 1 3 ( − 1 2 )

1 2 − 7 = 1 3 −1 2 )

1 2 − 7 = 1 3 − 1 2 )

Multiply by 1  

Combine multiplied terms into a single fraction  

Multiply by 1  

Add to both sides of the equation

Answer:

x = 3/2 = 1 1/2 = 1.5

Step-by-step explanation:

1/2 x -7=1/3(x-12)

Multiply 1/2 and -7 to get -7/2

-7/2 = 1/3(x-12)

Fraction -7/2 can be rewritten as -7/2 by extracting the negative sign.

- 7/2 = 1/3(x-12)

Use the distributive property to multiply 1/3 by x−12.

-7/2 = 1/3x + 1/3(-12)

Multiply 1/3 and −12 to get -12/3

-7/2 = 1/3x + -12/3

Divide −12 by 3 to get −4.

-7/2 = 1/3x + 4

Swap sides so that all variable terms are on the left hand side.

1/3x -4 = -7/2

Add 4 to both sides.

1/3x = -7/2 + 4

Convert 4 to fraction 8/2

1/3x = -7/2+8/2

Since -7/2 and 8/2 have the same denominator, add them by adding their numerators.

1/3x = -7+8/2

Add −7 and 8 to get 1.

1/3x = 1/2

Multiply both sides by 3, the reciprocal of 1/3

x = 1/2 x 3

Multiply 1/2 and 3 to get 3/2

x = 3/2
