The division of 41°48' by 4 gives the result 10°27'.
What is termed as the division?Multiplication is the inverse of division. If 3 groups of 4 add up to 12, 12 divided into 3 equal portions adds up to 4 in each group in division. Each component of a division eqn has its own name.Dividend: A dividend is indeed the number divided during the division process.Divisor: The divisor is the number in which the dividend is divided.Quotient: A quotient is an outcome of the division process.Remainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.The following describes the relationship between such four parts:
Dividend = Divisor x Quotient + Remainder
For the given expression,
(41°48') divided by 4.
= 41°48' / 4
= 10°27'.
Thus, the division of the expression 41°48' by 4 gives 10°27'.

How much money will be allocated to her savings?
1. The total earnings of the paralegal from this job was £4,680.
2. The amount of the earnings allocated to her savings, based on the allocation ratio, is £2,808.
What are the total earnings?The total earnings are a function of the unit hours worked and the hourly pay rate.
The total earnings are the product of the multiplication of the two variables.
What is a ratio?A ratio is a numerical relationship showing how much a value is contained in another value or variable.
Ratios are fractional values depicted in percentages, decimals, or fractions.
The total number of work hours = 19.5 hours
The work hour rate (per hour) = £240
The total earnings from the job = £4,680 (£240 x 19.5)
The ratio of utilities and savings = 2:3
The sum of the ratio = 5
The amount allocated to savings = 3/5 of £4,680 = £2,808.
The amount allocated to utilities = £1,872 or 2/5 (£4,680 - £2,808)
Thus, whereas, the paralegal earned £4,680 from the job, the amount allocated to her savings is £2,808, based on the subsisting allocation ratio.

Find all angles 0 theta such that 0 degrees are less than or equal to 0 theta and less than or equal to 360 degrees for which the statement sin(-104) = sin 0 theta is true
Hello there. To solve this question, we'll have to remember some properties about angles and the unit circle.
First, remember the unit circle:
An angle is represented as the measure between the line joining the origin and any point of the circle with the x-axis, as follows
The full angle in this case, representing a cycle in the circle is
[tex]\theta=2\pi[/tex]So we want to determine all angles θ between 0 and 360º such that
[tex]\sin(-104^{\circ})=\sin(\theta)[/tex]For this, we have to remember about first positive determination of an angle.
Notice we can represent negative angles in the unit circle if, instead of following in the anti-clockwise orientation (we say positive orientation), we follow the other way around:
But notice that we can represent these angles with our first case if you consider:
[tex]2\pi-\alpha[/tex]Since you have the property that the full angles is 2pi, hence
Thefore you have that
[tex]360^{\circ}-104^{\circ}=256^{\circ}[/tex]In this case notice that we added 360º to the angle, since we fixed the point of which the angle was at and gave it a full rotation.
For smaller angles, for example, -1352º, you can add the biggest possible multiple of 360º, that represents the number of full rotations you have to have in order to find its first positive determination.
In this case, we found that
[tex]\theta=256^{\circ}[/tex]Satisfying the property that

Answer:
Variable terms: 4a and 6a
Constant terms: 4 and 11
Step-by-step explanation:
A constant term is one that is NOT multiplied by any variables.
At this level of math, think of constants as terms that are only numbers.
(for example: 1, 68.9, -42, etc.)
Note that a term in « a + bi » form can also be a constant.
A variable term is a one that IS multiplied by a variable.
(for example x, -3y, 8z, etc.)
In question 1, the variable terms are:
4a and 6a because they are multiplied by the variable a
The constant terms are:
4 and 11 because they are simply integers
Note that the constant terms could also be written as -4 and -11 depending on how the operations are viewed (subtracting vs adding a negative)
lynn is tracking the progress of her plants growth. today the plant is 5 cm high. the plant grows 1.5 cm per day. suppose Lynn's plant grewn to a height of 30.5 inches how many days will have passed
We have that the plant start with 5 cm high and it grows 1.5 cm per day, then the equation to model this situation is:
[tex]y=1.5x+5[/tex]where x represents the days that passes and y represents the height of the plant.
Now, let's convert 30.5 inches to cm:
[tex]\begin{gathered} 1in=2.54\operatorname{cm} \\ \Rightarrow(30.5)\cdot(2.54)=77.47\operatorname{cm} \end{gathered}[/tex]then, suppose that Lynn's plant grew to a height of 77.47 cm, then we have to make y = 77.47 and solve for x to get the following:
[tex]\begin{gathered} y=77.47 \\ \Rightarrow77.47=1.5x+5 \\ \Rightarrow77.47-5=1.5x \\ \Rightarrow72.47=1.5x \\ \Rightarrow x=\frac{72.47}{1.5}=48.3 \\ x=48.3 \end{gathered}[/tex]therefore, it will take approximately 48 days to the plant to grow to a height of 30.5 inches

Is (A − B) − C = (A − C) − B exists equivalent?Given: (A − B) − C = (A − C) − B.
First, we will attempt to show [tex]$A-(B-C) \subseteq(A-C)-C$[/tex]. Let [tex]$x \in A-(B-C)$[/tex]. Then [tex]$x \in A$[/tex] and [tex]$x \notin(B-C)$[/tex].
By De Morgan's law we have that
[tex]$$x \notin(B-C)=x \notin B \vee x \in C .$$[/tex]
We have that [tex]$x \in A \wedge(x \notin B \vee x \in C)$[/tex].
Then we have that [tex]$(x \in A \wedge x \notin B) \vee(x \in A \wedge x \in C)$[/tex].
So by definition of [tex]$\cup$[/tex] and [tex]$\cap$[/tex], we have [tex]$x \in(A-B) \cup(x \in(A \cap C))[/tex].
I can see a contradiction here in that LHS says x ∈ C but the RHS says x ∉ C.

Then A - (B - C) = 4 - (2 - 1) = 4 - 1 = 3

Marian purchased a home valued at $465,000. She purchased homeowner insurance for 75% of the value of the home. If the annual premium on the policyhundred-dollar unit, how much did she pay to the nearest whole cent)?$2,875.50$2,695.00$2,580.75$3,050.74None of these choices are correct.
Ok, so
Marian purchased a home valued at $465,000. If She purchased homeowner insurance for 75% of the value of the home, she paid:
$(465,000)*(75) / (100)
$348,750.
Now, we know that the annual premium on the policy was $0.74 per hundred-dollar unit. Then, this is:
0.74/100 dollar unit.
And, if we multiply, we obtain:
$348,750 * (0.74/100) = $2,580.75
Therefore, she paid $2,580.75
A particular fruit's weights are normally distributed, with a mean of 598 grams and a standard deviation of 22 grams.
If you pick 9 fruits at random, then 16% of the time, their mean weight will be greater than how many grams?
Give your answer to the nearest gram.
If a particular fruit's weights are normally distributed, with a mean of 598 grams and a standard deviation of 22 grams and I pick 9 fruits at random, then their mean weight will be greater than 605.29263 grams 16% of the time.
As per the question statement, a particular fruit's weights are normally distributed, with a mean of 598 grams and a standard deviation of 22 grams and I pick 9 fruits at random.
We are required to calculate their mean weight will be greater than how many grams for 16% of the time.
Given (μ = 598), (σ = 22), and (n = 9)
Therefore, the standard deviation of the distribution of sample, otherwise know as the standard error, will be [s = (sdp)/√(ss)]
Where, "s" is the standard error, "sdp" is the standard deviation of the population and "ss" is the sample size.
Therefore, [s = (22/√9) = (22/3) = 7.33...
Now, we need to look up the z-score for an area to the right of it being equal to (0.16) since we are concerned about (16%) times among the random selection, and [16% = (16/100) = 0.16]
That is, we need to look up the z-score for an area of [(1 - 0.16) = 0.84] to the left of it.
Hence, a z-score with an area of 0.84 to the left of it will be equal to 0.99445.
Now to find the raw score associated with this, we will have to use the formula to calculate z-score which goes as [(x - m)/s].
Where, "z" is the z-score, "x" is the raw score, "m" is the mean and "s" is the standard error.
Therefore, with a mean of 598 and a standard error of 7.333 and a z-score of 0.99445, applied to the above mentioned formula to calculate z-score, we get:
[0.99445 = (x - 598)/7.33]
Or, (x - 598) = (0.99445 * 7.33)
Or, (x - 598) = 7.29263
Or, x = (598 + 7.29263)
Or, [x = 605.29263]
That is, if I pick a sample of 9 fruits at random, then their mean weight will be greater than 605.29263 grams 16% of the time.

[tex]\sum ^9_{i\mathop{=}1}20+2(i-1)[/tex]prove why the function is even with the green highlighted formulathen show where the line of symmetry is at show all work
Here, the given function is f(x)=c.
Check whether the function is odd or even.
[tex]\begin{gathered} f(-x)=c \\ =f(x) \end{gathered}[/tex]Here, the out put of the function is constant whether it is +x or -x.
So, the function is even.
The graph of the function f(x)=c is shown below.
From, the graph, for any values of x there is a constant val;ue of y.
The function is symmetric with respect to y axis.
The first 19 terms of the arithmetic sequence 9, 2, -5, -12,...
9, 2, -5, -12,...
First let's find the common difference
Common difference= 2 - 9 = -7
So we will add - 7 to get the next term
9, 2, -5, -12, -19, -26, -33,-40, -47, -54, -61, -68, -75, -82, -89, -96, -103, -110, -117
