Given:
The inequality must be solved.
The process of solving an inequality consists of determining the values of the variable that make the statement true.
The definition of inequality is where one quantity is greater than or less than another.
Solutions:
9-4r>5First, subtract by 9 from both sides.
[tex]:\Longrightarrow \sf{9-4r-9 > 5-9}[/tex]
Solve.
5-9=-4
-4r>-4
Multiply by -1 from both sides.
[tex]\Longrightarrow: \sf{\left(-4r\right)\left(-1\right) < \left(-4\right)\left(-1\right)}[/tex]
Solve.
4r<4
Divide by 4 from both sides.
4r/4<4/4
Solve.
4/4=1
[tex]\Longrightarrow: \boxed{\sf{r < 1}}[/tex]
Therefore, the final answer is r<1.I hope this helps, let me know if you have any questions.

Answer:
x = 145 degrees
Step-by-step explanation:
In leftmost triangle, missing angle :
= 180 - (90 + 35)
= 55 degrees
Top angle of middle triangle :
= 180 - (60 + 55)
= 180 - 115

Bottom angle of middle triangle :

Used calculator!
============================================================
Explanation:
The "per cupcake" means "for each cupcake" or "for 1 cupcake".
To get that initial "8 cupcakes" into "1 cupcake", we divide both given values by 8
8/8 = 132/8 = 4The ratio 8 cupcakes : $32 then becomes 1 cupcake : 4 dollars
In other words, the unit cost is 4 dollars per cupcake.

a) This is not a random sample
b) The generalization from this sample would not be valid
Step-by-step explanation:
No the sample is not random. If the questionnaire would had been send to any five students in a class irrespective of whether they are among the top five, then the sample could be referred as random sample.
The marks of top five students in any grade would give an average value that will be an outlier to the average of marks of all students with in a grade.
Hence, the generalization from this sample would not be valid

Answers
The area under the shaded region from 1 to 2 is 0.14
What will be the shaded region area?Probabilities actually define the percentage of the happening of an event
Here the shaded region shows the probability of the z-scores
The shaded region 1 to 2 is represented as:
[tex]P(1 < z < 2)[/tex]
By using the probability of z-score we can have
[tex]P(1 < z < 2)=P(z < 2)-P(z < 1)[/tex]
From the given standard normal table:
[tex]P(z < 2)=0.9772[/tex]
[tex]P(z < 1)=0.8413[/tex]
So, we have:
[tex]P(1 < z < 2)=0.9772-0.8413[/tex]
[tex]P(1 < z < 2)=0.1359[/tex]
The approximated value will be
[tex]P(1 < z < 2)=0.14[/tex]
Thus the area under the curve shaded is 1 to 2 is 0.14

Serenity is moving and must rent a truck. There is an initial charge for the rental plus
a fee per mile driven. The total cost of renting the truck can be modeled by the
equation C = 50 +2.75m, where m is the number of miles driven. What is the y-
intercept of the equation and what is its interpretation in the context of the problem?
Answers
Answer:
The y-intercept of the equation is 50
Its interpretation in the context is " the initial charge for the rental "
Step-by-step explanation:
The linear relationship can be represented by the equation
y = a x + b, where
a is the slope ( the rate of change)b is the y-intercept (initial amount, or fixed amount, or the amount of y at x = 0)∵ Serenity is moving and must rent a truck
∵ There is an initial charge for the rental
∴ b represents the initial charge for the rental
∵ There is a fee per mile driven
∴ a represents the fee per mile driven
∵ The equation represents this situation is C = 50 + 2.75 m
∵ C is the total cost
∵ m is the number of miles driven
→ Compare it with the form of the equation above
∴ a = 2.75
∴ b = 50
∵ b is the y-intercept
∴ The y-intercept of the equation is 50
∵ b represents the initial charge for the rental
∴ The initial charge for the rental is $50
∴ Its interpretation in the context is " the initial charge for the rental "

colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan start with 80 of a different type of bacteria that doubles every 3 hours
Answers
Step-by-step explanation:
so, what is the question ?
all you are giving us here are some facts about what's going on. but what is the goal ? what do we need to find out ?
is it when the bacteria cultures have the same population ?
I assume that for my following answer :
"once every 2 hours" can be expressed by "x/2". with x being hours. so, instead of "x", which would mean "once every hour", we use "x/2".
"doubles (once) every 2 hours" is then
2×2×2×...×2 doubles on how many units of 2 hours we have.
this is
2^(x/2)
this is the factor we need to multiply with everything we want to behave that way (to double in size every 2 hours).
in our case here : 50 bacteria.
so, Colby's bacteria culture function is
c(x) = 50 × 2^(x/2)
similar for jaquan:
j(x) = 80 × 2^(x/3)
as his culture doubles every 3 hours.
now for the assumed question, when will both cultures have the same population ?
it is for that value of x that makes both function to deliver the same functional result.
50 × 2^(x/2) = 80 × 2^(x/3)
5 × 2^(x/2) = 8 × 2^(x/3)
now we use the log2 function on both sides and get
log2(5 × 2^(x/2)) = log2(8 × 2^(x/3))
remember the laws of logarithm. particularly
log(a×b) = log(a) + log(b)
and
loga(b) = logc(b)/logc(a)
log2(5) + log2(2^(x/2) = log2(8) + log2(2^(x/3)
log2(5) + x/2 = log2(8) + x/3 = 3 + x/3
3×log2(5) + 3x/2 = 9 + x
2×3×log2(5) + 3x = 2×9 + 2x
6×log2(5) + 3x = 18 + 2x
x = 18 - 6×log2(5) = 18 - 6×ln(5)/ln(2) = 4.068431431... hours
so, after a little bit more than 4 hours both bacteria cultures reach the exact same number of population : 204.8
which is, of course, only theoretical, as there cannot be "part bacteria" in the cultures.
now, we could calculate the x for when c(x) = 204, and the x for when c(x) = 205.
and then the same for j(x) and then see if or what overlap between these two x intervals there is.
during this overlap period both cultures will have the same (whole number) amount of bacteria.
but I think this is a topic for another question, as I am not even sure that I addressed the true original question.

A triangle has two sides of length 11 and 12. What is the smallest possible whole-number length for the third side?
Answers

To maximize the length of the third side, which I'll call x, it needs to be one of the two shorter sides.

The ratio of art class to music class is 4:3. If there is 8 more students in art class, how many students are in music class
Answers
Answer:
9 students in music class.
Step-by-step explanation:
In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.
4 x _ = 12. —> 4 x 3 = 12.
so we need to do the same for music class.
For music there are 3.
so we multiply by 3 like we did with the 4.
3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.
