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
Answer:
A,B,D
Step-by-step explanation:
You are given the task of building detention ponds to remove settleable solids from a small stream prior to discharge into a lake. The ponds must be 2 m deep, the flow in the stream is 20 cfs, the solids settle at a rate of 0.2 m/day, and you must achieve a steady-state removal of 65% of the solids.
a. Determine the size of a single CSTR to achieve the desired removal.
b. Determine the sizes of a pair of identical CSTRs in series needed to achieve the desired removal.
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

Hiro rolls a fair pair of six-sided dice. The sample space of all possible outcomes is shown below.
Let AAA be the event that the first die is one and BBB be the event that the sum of the dice is eight.
What is P(A\text{ or }B)P(A or B)P, left parenthesis, A, start text, space, o, r, space, end text, B, right parenthesis, the probability that the first die is one or the sum of the dice is eight?
\qquad
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]

Can someone help me find the value of N in the triangle and round the answer to two decimal places
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)

— 3х – 6+(-1)
do anybody know this answer
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.
