I suppose the question is what is Thaddeus' time to make the trip. This is a fairly common question but not everyone knows how to solve it.
Derivation of the Formula
Prescott + Thaddeus = 1 trip
So the logic of the equation is this.
distance = 1 trip
time = number of dates
rate = ?
rate = distance / time
To find out what the contribution of Thaddeus is set up a distance time formula.
1/21 days is the rate for Prescott
1/x days is the rate for Thaddeus
Together the rate is 1/9
Solution
1/21 + 1/x = 1/9
Subtract 1/21 from both sides
1/x = 1/9 - 1/21
It's not obvious what the LCM is.
9 = 3 * 3
21 = 3 * 7
LCM: 7 * 3 *3 = 63
1/x = 7/63 - 3/63 = 4/63
1/x = 4/63 Cross Multiply
4x = 63 Divide by 4
x = 63/4
Answer
x = 15 3/4
x = 15.75

A random sample of students were asked whether they prefer milk juice or water is it results are summarized in the table.
Answer:
C
Step-by-step explanation:
The probability of students response is milk is 0.311.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
The table shows the students preference of milk, juice or water.
Total number of students preferred milk = 14
Total number of students = 45
Thus the probability that the students response is milk is
[tex]P(e)=\frac{14}{45}[/tex]
⇒ [tex]P(e)= 0.311[/tex]
Hence we can conclude that the probability of students response is milk is 0.311.

Step-by-step explanation:
Suppose the missing polynomial be f(x)
So, we can write
[tex]\Rightarrow f(x)-(20-4x+5x^2)=20-7x^2\\\Rightarrow f(x)=20-7x^2+(20-4x+5x^2)\\\Rightarrow f(x)=-2x^2-4x+40[/tex]
Four friends shared 3 orders of chicken wings. • Alex ate 5 of an order. ·8· • Chase ate 7 of an order. ·8· • Ella ate 6 of an order. ·8· How much chicken is left for the fourth friend?
Answer: 3/4
Step-by-step explanation:
Amount of chicken ordered = 3
Fraction eaten by Alex = 5/8
Fraction eaten by Chase = 7/8
Fraction eaten by Ella = 6/8
The chicken ate by the three friends will be:
= 5/8 + 7/8 + 6/8
= 18/8
= 2 2/8
= 2 1/4
Now, the chicken left for the forty friend will be:
= 3 - 2 1/4
= 3/4

Solve the right triangle. Round decimal answers to the nearest tenth. I can´t figure out KL and ML.
Answer:
Me to I need that Answer en m<k is 50°
Step-by-step explanation:
The measure of KL is 5.1 unit and the measure of ML is 6.1 unit.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, MK=8 units, ∠M=40° and ∠K=50°.
We know that, sinθ=Perpendicular/Hypotenuse
Now, sin40°=KL/8
0.6427=KL/8
KL=0.6427×8
KL=5.1 units
sin50°=ML/8
0.7660=ML/8
ML=6.1 units
Therefore, the measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

Answer:
3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer
