Paul is 2 years younger than patricia. Daniel is 25% older than Patricia. Ten years ago, Daniel was 50% older than Patricia. How old is paul currently.
Daniel is 25% older than Patricia. Ten years ago, Daniel was 50% older than Patricia.
That gives us the equations 1.25d=p and 1.5(d−10)=(p−10). Solving gives us 25 for Daniel and 20 for Patricia.
Paul is two years younger than Patricia.
20−2=18
To solve the problem, we set up an equation based on the given relationships and information. After solving it, we find that Patricia is 40 years old and Paul (who is 2 years younger) is 38 years old.
Explanation:Let's denote Patricia's current age as 'P', Paul's age as 'P-2' (since Paul is 2 years younger than Patricia), and Daniel's age as 'P+0.25P' (since Daniel is 25% older than Patricia).
According to the problem, ten years ago, Daniel was 50% older than Patricia. So, we create the equation '0.5(P-10) = P+0.25P-10' to represent this situation.
Solving the equation, we find P (Patricia's current age) equals 40 years. Hence, Paul's current age would be 'P-2', which is 38 years.

Which function represents a line with a slope of ?4 and a y-intercept of ?2? A) y = 4x ? 2 B) y = ?4x + 2 Eliminate C) y = ?4x ? 2 D) y = ?2x ? 4
Answer:
A function describes this way is y = 4x + 2
Step-by-step explanation:
In order to find this, we have to start with slope-intercept form.
y = mx + b
Knowing this, we can then input the slope in for m and the intercept in for b. This will give us the equation.
y = 4x + 2

Answer:
Cubic
Step-by-step explanation:
A cubic function is a function whose degree is 3 (the highest exponent or power on the variable). It has a distinctive sideways S shape that can either start down and end up or start up and end down. It also crosses through the x-axis an odd number of times. It will have up to three x-intercepts or roots.
In a right triangle one acute angle measures 48 more than 2 times the other. If the sum of the measure of the two acute angles must equal 90 find the measure is the acute angles
A)14,76 B)16,74 C)15,78. D)13,77
Answer:
A
Step-by-step explanation:
let one acute angle be x then the other is 2x + 48
Their sum is 90 , hence
x + 2x + 48 = 90
3x + 48 = 90 ( subtract 48 from both sides )
3x = 42 ( divide both sides by 3 )
x = 14
the 2 acute angles are x = 14° and (2 × 14 ) + 48 = 28 + 48 = 76°

find the polynomial function
Answer:
y = 2x³ +x² -3x +6
Step-by-step explanation:
The polynomial correlation function of a graphing calculator can work with the table of function values to give you the equation. (See attached)
_____
If you want to solve this by hand, you can write the equations for the unknown coefficients in the polynomial function, then solve those. First of all, notice that you are given the y-intercept, (0, 6), so you know one of the coefficients already. That leaves a system of 3 equations in 3 unknowns that need to be solved.
___
Writing the equations
... ax³ +bx² +cx +6 = y . . . . the generic linear equation in a, b, c that you're writing
For x = -1:
... -a +b -c +6 = 8
For x = 1
... a + b + c + 6 = 6
For x = 2
... 8a +4b +2c +6 = 20
In augmented matrix terms, this set of linear equations looks like ...
[tex]\left[\begin{array}{ccc|c}-1&1&-1&2\\1&1&1&0\\8&4&2&14\end{array}\right][/tex]
___
Solving the equations
There are a number of ways to solve these. Again, a graphing calculator often has solution functions, such as reducing a matrix to row-echelon form, that will solve this in a keystroke or two.
If you add the first two equations, you get ...
... 2b = 2 ⇒ b = 1
Substituting that into the first equation allows you to simplify it to ...
... -a -c = 1
Dividing the third equation by 2 (and substituting for b) makes it ...
... 4a +c = 5
Adding these equations gives ...
... 3a = 6 ⇒ a = 2
Then ...
... c = -a -1 = -2 -1 = -3
And our polynomial function is ...
... y = 2x³ +x² -3x +6

Answer:
The answer is x = 7
Step-by-step explanation:
√2x − 5 + 4 = x
= √2x − 5 + 4 + − 4 = x + −4 (add -4 to both sides)
=√2x − 5 = x − 4
=√2x−5=x−4
2x−5=(x−4)2 (Square both sides)
2x−5=x2−8x+16
2x−5−(x2−8x+16)=x2−8x+16−(x2−8x+16)(Subtract x^2-8x+16 from both sides)
−x2+10x−21=0
(−x+3)(x−7)=0 (Factor left side of equation)
−x+3=0 or x−7=0 (Set factors equal to 0)
x=3 or x=7
Answer: 7
Step-by-step explanation:
[tex]\sqrt{2x-5}+4 = x[/tex]
Restriction: x ≥ 4 why? because [tex]\sqrt{2x-5}\geq0[/tex]
[tex]\sqrt{2x-5}+4 = x[/tex]
-4 -4
[tex]\sqrt{2x-5} = x - 4[/tex]
[tex](\sqrt{2x-5})^2 = (x - 4)^2[/tex]
2x - 5 = x² - 8x + 16
-2x +5 -2x +5
0 = x² - 10x + 21
0 = (x - 3) (x - 7)

Robbie Morse has a $47,500 insurance policy. The annual premium is $987.53. Robbie pays $90.00 monthly.
How much does Robbie pay in twelve months?
$
How much more does Robbie pay?
$
What percentage does Robbie pay (to the nearest percent)?
%
Answer:
Robbie pay in twelve months $1080 .
$92.47 more Robbie pay and 9.36 %(Approx) Robbie pay.
Step-by-step explanation:
As given
Robbie Morse has a $47,500 insurance policy.
The annual premium is $987.53.
Robbie pays $90.00 monthly.
First find out the Robbie pay in twelve months .
Robbie pay in twelve months = 12 × 90
= $ 1080
Second find out how much more does Robbie pay .
Robbie pay extra = Robbie pay in twelve months - annual premium
= $ 1080 - $987.53
= $92.47
Therefore the $92.47 more Robbie pay .
Third find out the what percentage does Robbie pay .
Formula
[tex]Percentage = \frac{Robbies\ pay\ more\times 100}{annual\ premium}[/tex]
Robbies pay more = $92.47
Annual premium = $987.53
Put in the above
[tex]Percentage = \frac{92.47\times 100}{987.53}[/tex]
[tex]Percentage = \frac{9247}{987.53}[/tex]
Percentage = 9.36 % (Approx)
9.36 %(Approx) Robbie pay.
Robbie pays a total of $1,080.00 over twelve months, which is $92.47 more than the annual premium. This amount is approximately 9% more than the original annual premium.
To determine how much Robbie pays for his monthly premium over twelve months, we need to perform the following calculations:
First, calculate the total amount Robbie pays monthly. He pays $90.00 monthly, so over twelve months:
$90.00 times 12 = $1,080.00
Next, we need to find out how much more Robbie pays compared to the annual premium of $987.53:
$1,080.00 - $987.53 = $92.47
Percentage Calculation:
To find the percentage Robbie pays compared to the original annual premium, use the formula:
(difference / original amount) times 100
($92.47 / $987.53) times 100 ≈ 9%
Thus, Robbie pays approximately 9% more than the annual premium.

On a piece of paper graph f(x)=-1
Answer:

Unfortunately, I'm having file upload issues so I'll just say what it is. f(x) means value of the function, which is the y-value. So you're basically plotting y=-1. No matter what your x-value is, the y-value is always -1. So, it is a horizontal line crossing -1 on the y-axis, extending to infinity on either side.

Eric estimated 28x48 by finding 30x50. His estimate was 1,500,but he says the actual product will be greater than that amount.Is he correct? Explain how you know
Answer:
Eric is not correct.
Step-by-step explanation:
We have been given that Eric estimated [tex]28\times 48[/tex] by finding [tex]30\times 50[/tex]. His estimate was 1500, but he says the actual product will be greater than that amount.
To find if Eric is correct or not, let us see how to estimate an answer.
While estimating our given numbers we will round to nearest tenth and change the digit to the right of the rounding place to 0.
As 8 is greater than 5, so we will round 28 to 30 and 48 to 50.
Since we are rounding up, so our estimated answer will be greater than actual answer, therefore, Eric is not correct.

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each other along a trail at 8:00 am with a plan to have a picnic when they meet if kiran walks 3 miles per hour while clare walks 3.4 miles per hour. At what time will the two friends meet and have their picnic
Answer:
[tex]11:45\ am[/tex]
Step-by-step explanation:
Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.
Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.
So the relative speed of them is,
[tex]=3+3.4=6.4[/tex] miles/hr
Both the speed are added as they moving in opposite direction.
We know that,
[tex]\text{Relative speed}=\dfrac{\text{Relative distance}}{\text{Time}}[/tex]
i.e [tex]\text{Time}=\dfrac{\text{Relative distance}}{\text{Relative speed}}[/tex]
Putting the values,
[tex]t=\dfrac{24}{6.4}=3.75\ hr=3\ hr\ 45\ min[/tex]
As they started at 8.00 am, so the time at which will meet will be,

Two events E1 and E2 are called independent if p(E1 â© E2) = p(E1)p(E2). For each of the following pairs of events, which are subsets of the set of all possible outcomes when a coin is tossed three times, determine whether or not they are independent. a) E1: tails comes up with the coin is tossed the first time; E2: heads comes up when the coin is tossed the second time. b) E1: the first coin comes up tails; E2: two, and not three, heads come up in a row. c) E1: the second coin comes up tails; E2: two, and not three, heads come up in a row.
Answer: a) Independent
b) Independent
c) Dependent
Step-by-step explanation:
Since, If a coin is tossed three times,
Then, total number of outcomes, n(S) = 8
a) [tex]E_1[/tex] : tails comes up with the coin is tossed the first time;
[tex]E_1[/tex] = { TTT, THH, THT, TTH }
[tex]E_2[/tex] : heads comes up when the coin is tossed the second time.
[tex]E_2[/tex] = { THT, HHH, THH, HHT }
Thus, [tex]n(E_1)=4[/tex]
⇒ [tex]P(E_1)=\frac{n(E_1)}{n(S)}=\frac{4}{8}=\frac{1}{2} [/tex]
Similarly, [tex]P(E_2)=\frac{1}{2}[/tex]
⇒ [tex]P(E_1)\times P(E_2)=\frac{1}{2}\times \frac{1}{2}=\frac{1}{4} [/tex]
Since, [tex]E_1\cap E_2 [/tex] = { THH, THT }
[tex]n(E_1\cap E_2) = 2 [/tex]
⇒ [tex]P(E_1\cap E_2) = \frac{n(E_1\cap E_2)}{n(S)}= \frac{2}{8}=\frac{1}{4}[/tex]
Thus, [tex]P(E_1\cap E_2)=P(E_1)\timesP(E_2)[/tex]
Therefore, [tex]E_1[/tex] and [tex]E_2[/tex] are independent events.
B) [tex]E_1[/tex] : the first coin comes up tails
[tex]E_1[/tex] = { TTT, THH, THT, TTH }
[tex]E_2[/tex] : two, and not three, heads come up in a row
[tex]E_2[/tex] = { HHT, THH }
Thus, [tex]n(E_1)=4[/tex]
⇒ [tex]P(E_1)=\frac{n(E_1)}{n(S)}=\frac{4}{8}=\frac{1}{2} [/tex]
Similarly, [tex]P(E_2)=\frac{1}{4}[/tex]
⇒ [tex]P(E_1)\times P(E_2)=\frac{1}{2}\times \frac{1}{4}=\frac{1}{8} [/tex]
Since, [tex]E_1\cap E_2 [/tex] = { THH }
[tex]n(E_1\cap E_2) = 1 [/tex]
⇒ [tex]P(E_1\cap E_2) = \frac{n(E_1\cap E_2)}{n(S)}= \frac{1}{8}[/tex]
Thus, [tex]P(E_1\cap E_2)=P(E_1)\timesP(E_2)[/tex]
Therefore, [tex]E_1[/tex] and [tex]E_2[/tex] are independent events.
C) [tex]E_1[/tex] : the second coin comes up tails;
[tex]E_1[/tex] = { HTH, HTT, TTT, TTH }
[tex]E_2[/tex] : two, and not three, heads come up in a row
[tex]E_2[/tex] = { HHT, THH }
Thus, [tex]n(E_1)=4[/tex]
⇒ [tex]P(E_1)=\frac{n(E_1)}{n(S)}=\frac{4}{8}=\frac{1}{2} [/tex]
Similarly, [tex]P(E_2)=\frac{1}{4}[/tex]
⇒ [tex]P(E_1)\times P(E_2)=\frac{1}{2}\times \frac{1}{4}=\frac{1}{8} [/tex]
Since, [tex]E_1\cap E_2 [/tex] = [tex]\phi[/tex]
[tex]n(E_1\cap E_2) = 0 [/tex]
⇒ [tex]P(E_1\cap E_2) = 0[/tex]
Thus, [tex]P(E_1\cap E_2)\neq P(E_1)\timesP(E_2)[/tex]
Therefore, [tex]E_1[/tex] and [tex]E_2[/tex] are dependent events.

The critical path in a project schedule is the longest sequence of tasks from start to finish and determines the minimum total duration for the project. Without the diagram, the correct duration from your multiple-choice options cannot be determined accurately. The correct answer represents the duration of the longest path from the given options.
Explanation:Without the graphic showing the schedule network diagram for assembling a toy train set, providing an accurate answer would be difficult. Normally, in project management, a Critical Path represents the longest sequence of tasks (or activities) in a project schedule from start to finish. It determines the minimum total duration required to complete the project. You identify the critical path by adding the times for the activities in each sequence and determining the longest path in the project.
In this case, assuming that you have the diagram in front of you and you've calculated the total duration for all paths, one of the multiple choice options (A) 38 minutes, (B) 41 minutes, (C) 49 minutes, or (D) 51 minutes would represent the duration of the critical path in the network diagram.

By hit and trial method, if we put x = 2 and y = 10 then the resulting equation (1) is satisfied and all the conditions hold.
So, the denominators are 2 and 10
Through the hit and trial method, the value of the denominator 'a' is 2 and the value of denominator 'b' is 10 and there is also the use of arithmetic operations.
Given :
Noah is thinking of two fractions that have the same sum of 3/5.Each fraction has a numerator of 1.To determine the denominator of the two fractions whose sum is 3/5, first, let that numbers be 1/a and 1/b.
[tex]\dfrac{1}{a}+\dfrac{1}{b}= \dfrac{3}{5}[/tex]
[tex]5a + 5b = 3ab[/tex]
Now, put a = 2 then b becomes:
[tex]10 + 5b = 6b[/tex]
b = 10
So, through the hit and trial method, the value of a is 2 and the value of b is 10.

Answer:
See below
Step-by-step explanation:
m < 1 = 180 - m<4 (supplementary angles)
= 180 - 143
= 37 degrees
m <2 = m< 4 ( opposite angles)
= 143 degrees
M< 3 = m < 1 = 37 degrees (opposite angle)
Angle 1 measures 143 degrees, while angles 2 and 3 both measure 37 degrees.
To find the measure of angle 2, we can use the fact that adjacent angles on a straight line are supplementary. This means that angle 2 and angle 4 add up to 180 degrees. Since angle 4 is 143 degrees, angle 2 is 180 - 143 = 37 degrees.
To find the measure of angle 3, we can use the fact that corresponding angles of parallel lines cut by a transversal are congruent. This means that angle 3 and angle 2 have the same measure. Since angle 2 is 37 degrees, angle 3 is also 37 degrees.
Therefore, the measures of angle 1, 2, and 3 are 143 degrees, 37 degrees, and 37 degrees, respectively.
