Answer:
m < [tex]\frac{36}{31}[/tex]
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-7+5*(9*m-7)-(9*m-2-9)<0
Step by step solution :
STEP 1
:
Equation at the end of step 1
(-7 + 5 • (9m - 7)) - (9m - 11) < 0
STEP 2
:
Equation at the end of step 2
36m - 31 < 0
STEP 3:
3.1 Divide both sides by 36
m-(31/36) < 0
Solve Basic Inequality :
3.2 Add 31/36 to both sides
m < [tex]\frac{31}{36}[/tex]
A recipe says, "1 part cocoa to 4 parts sugar." How much sugar will you need if you use 20 grams of cocoa?

Find the unit rate for number of parts manufactured per hour if 1620 parts are made in 6 hours.
Answer:
270 parts per hour
Step-by-step explanation:
given
we are told that 1620 parts are manufactured in 6 hours.
Required
Unit rate.
The unit rate in this context is defined as the number of parts that can be manufactured in one hour
Step two:
To find the unit rate, we have to divide the total parts manufactured by the total time taken
unit rate= 1620/6
unit rate= 270 parts per hour

The ratio of three numbers is 4 : 5 : 3. The sum of the numbers is 54. List the numbers in ratio form.
Answer:
13.5 : 18 : 22.5.
Step-by-step explanation:
let the numbers be 3x , 4x and 5x
3x+ 4x + 5x = 54
12x = 54
x = 4.5
so the numbers are 3*4.5, 4 * 4.5 and 5 * 4.5
= 13.5, 18 and 22.5.
The list of the numbers in ratio form is 18 : 22.5 : 13.5
Given the ratio of three numbers as 4 : 5 : 3
Total ratio = 4 + 5 + 3
Total ratio = 12
If the sum of the numbers is 54.
For the ratio of 4:
= 4/12 * 54
= 1/3 * 54
= 18
For the ratio of 5:
= 5/12 * 54
= 270/12
= 22.5
For the ratio of 3:
= 3/12 * 54
= 1/4 * 54
= 13.5
Hence the list of the numbers in ratio form is 18 : 22.5 : 13.5

My homework says, "Does the graph represent a proportional relationship? Why or why not? You MUST explain to get credit."
Answer:
No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0). ... It's not proportional because the line does not cross through the origin. Therefore the ratio of x to y will be different for two different points on the line.
Choose whether the expression is a result of multiplying
conjugates together, squaring binomials, or neither.
25c^2 + 55c + 30
-multiplying conjugates
-squaring binomials
-neither
-both
Answer:
neither
Step-by-step explanation:
Take out 5 as a common factor. It will be easier to look at.
5(5c^2 + 11c + 6)
5(5C +6 )(c + 1 )
Now you can put the 5 inside.
(25c + 30)(c + 1) is one answer.
(5c + 6)(5c + 5) is another.
The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.

! 2 red cards !
Step-by-step explanation:
Sia draws blue cards for each of her 3 turns: 4 • 3= 12
Sia draws red cards and ends up back at 0: 6 • 2 = 12
12 - 12 = 0
Sia drew 2 red cards since 6 • 2 = 12.

Situation:
A 33 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1473.
N = Noe
-kt
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
Find the substances half life, and days. Round your answer to the nearest 10th
Answer:
Half life = 4.7 days
Step-by-step explanation:
Formula to get the final amount of the substance after the time 't',
[tex]N_t=N_0e^{-kt}[/tex]
Here, [tex]N_t[/tex] = Final amount of the substance
[tex]N_0[/tex] = Initial amount
k = decay constant
t = Duration or time
Now by substituting the values in the formula,
[tex]N_t=N_0e^{-0.1473t}[/tex]
If [tex]N_t=\frac{1}{2}(N_0)[/tex] [For half life]
[tex]\frac{1}{2}(N_0)=N_0e^{-0.1473t}[/tex]
[tex]\frac{1}{2}=e^{-0.1473t}[/tex]
[tex]2=e^{0.1473t}[/tex]
ln(2) = [tex]\text{ln}(e^{0.1473t})[/tex]
0.69315 = 0.1473t
t = 4.71 days
t ≈ 4.7 days
Therefore, half life of the substance is 4.7 days.

The domain for f(x) and g(x) is the set of all real numbers.
Let f(x) = 3x + 5 and g(x) = x2.
Find f(x) + g(x).
Answer:
f(x) + g(x) = x^2 + 3x + 5
Step-by-step explanation:
In order to do this, you need to substitute f(x) for 3x +5 and substitute g(x) for x2 (which I'm assuming is x squared, which I will be wrIting as x^2. If this is not the problem, please correct me)
f(x) + g(x) = 3x + 5 + x^2
Now, you need to put the varibles in decreasing order of exponents.
f(x) + g(x) = x^2 + 3x + 5
Answer:
Step-by-step explanation:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence
pragnesh and roghui = [tex]\frac{1}{3}[/tex]
qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence
time taken when they all work together
= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]
= [tex]\frac{13}{12}[/tex]
= [tex]\frac{12}{13}[/tex]

Step-by-step explanation:
4 + [tex]\frac{n}{3}[/tex] = 2
[tex]\frac{n}{3}[/tex] = -2
n = -6
Answer:
n = -6
Step-by-step explanation:
4 + n/3 = 2
subtract 4 from both sides
n/3 = 2 -4
n/3 = -2
multiply both sides by 3
n = 3(-2)
n = -6
