The value of all four numbers will be 91, 98, 105, 112 respectively.
Let the first multiple be 7x
As the multiple of any number can be determined by simply multiplying the given number by the natural number or the counting numbers.
So, the value of the second multiple of 7 will be 7(x+1)
The value of third multiple of 7 will be = 7(x+2)
The value of fourth multiple of 7 will be = 7(x+3)
As all the multiple are consecutive so we have taken the multiplying factor as x, (x+1), (x+2) and (x+3)
From the data given in the question:
Sum = 7x+7x+7+7x+14+7x+21 = 406
=>28x+42=406
=>28x=364
=>x=(364/28)=13
So, the value of first multiple = 7x = (7*13) =91
So, the value of the second multiple of 7 will be 7(13+1)=98
The value of third multiple of 7 will be = 7(x+2)=7(13+2)=105
The value of fourth multiple of 7 will be = 7(x+3)=7(13+3)=112

Trapezoid MNPQ is similar to Trapezoid RSTU. What is the length of the "x" on the misside side NP ? Also, what is the length of "y" on the missing side TU?
Answer:
[tex]x = 15[/tex]
[tex]y = 25[/tex]
Step-by-step explanation:
Given
See attachment for MNPQ and RSTU
Required
Find x and y
To solve this question, we make use of equivalent ratios of corresponding side lengths.
The ratio of corresponding sides are:
[tex]MN : RS[/tex]
[tex]NP : ST[/tex]
[tex]PQ : TU[/tex]
[tex]MQ : RU[/tex]
From the attachment, we have:
[tex]MN : RS \to 18 : 30[/tex]
[tex]NP : ST \to x : 25[/tex]
[tex]PQ : TU \to 15 : y[/tex]
To solve for x, we equate [tex]MN : RS[/tex] and [tex]NP : ST[/tex]
[tex]18 : 30 = x : 25[/tex]
Express as fraction
[tex]\frac{18 }{ 30 }= \frac{x }{ 25}[/tex]
Make x the subject
[tex]x = 25 * \frac{18 }{ 30 }[/tex]
[tex]x = \frac{25 * 18 }{ 30 }[/tex]
[tex]x = \frac{450}{ 30 }[/tex]
[tex]x = 15[/tex]
To solve for y, we equate [tex]MN : RS[/tex] and [tex]PQ : TU[/tex]
[tex]18 : 30 = 15 : y[/tex]
Express as fraction
[tex]\frac{18 }{ 30 }= \frac{15 }{ y}[/tex]
Make y the subject
[tex]y = 15 * \frac{30 }{ 18 }[/tex]
[tex]y = \frac{15 *30}{ 18 }[/tex]
[tex]y = \frac{450}{ 18 }[/tex]
[tex]y = 25[/tex]

Which graph represents a relation that is NOT a function
Answer:
3) if you were to draw vertical lines through this graph you would have instances where an 'x' value would have more than one unique 'y' value
Step-by-step explanation:
functions must have one unique 'y' value for each 'x' value
The third graph represent a relation that is not a function
What is a function?A relation is a function if it has only One y-value for each x-value.
The third one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).
In order to see it better, you can trace a vertical line onto that graph.
If that line and the graph intersects in more than one point, then that graph doesn't represent a function.
In every function, you must have a single "y" value for each "x" in the domain.
Hence, the third graph represent a relation that is not a function

What are the coordinates of the focus of the parabola?
A: (8, 6)
B: (-8, 6)
C: (-8, 2)
D: (8, 2)
Answer:
C: (-8, 2)
Step-by-step explanation:
Given parabola:
[tex]y=-\dfrac{1}{8}x^2-2x-4[/tex]
For the quadratic equation in the form y = ax² + bx + c, the x-value of the vertex is -b/2a.
Therefore, the x-value of the vertex of the given parabola is:
[tex]\implies x=-\dfrac{b}{2a}=-\dfrac{-2}{2\left(-\frac{1}{8}\right)}=-8[/tex]
To find the y-value of the vertex, input x = -8 into the given equation:
[tex]\implies y=-\dfrac{1}{8}(-8)^2-2(-8)-4=4[/tex]
Therefore, the vertex (h, k) of the parabola is (-8, 4).
The focus of the parabola is (h, k+p) where:
(h, k) is the vertex[tex]p=\dfrac{1}{4a}[/tex]Therefore:

20 workers can paint a building in 21 days. If work has to be finished in 15 days, find the number of extra workers required.
Step-by-step explanation:
20 workers finish work in 21 days.
the necessary work effort is 20×21 = 420 workdays.
the same effort is needed even if the overall time is shorter.
x workers in 15 days.
x × 15 = 420
x = 420/15 = 28 workers.

Find the largest prime number that divides the quantity 0! + (1!) x 1 + (2!) x 2 + (3!) x 3 + ... + (50!) x 50
The largest prime number that divides the quantity is the largest prime number less than 5.5e+22.
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A prime number that divides a quantity is a prime number that is a factor of that quantity.
We can start by computing the values of the factorials, and then use the property of modular arithmetic to find the prime divisors of the quantity.
0! = 1
1! = 1
2! = 2
3! = 6
...
50! = 30414093201713378043612608166064768844377641568960512000000000000
Now we can write the expression as
(0! + 1x1!) + (2x2!) + (3x3!) + ... + (50x50!)
We can notice that the number is very large, and it's impractical to factorize it using traditional methods.
We can use the property that if n is not divisible by a prime number p, then n! is not divisible by p^2. So we can eliminate all the powers of 2 and 5 from the expression, since 2 and 5 are the only prime factors of the factorials.
The next step would be to check if the remaining number is divisible by any prime numbers.
Since it's impractical to check for all the prime numbers, we can use the fact that the largest prime number is less than the square root of the number in question. Therefore, we can check for all primes less than √(50!) = √(30414093201713378043612608166064768844377641568960512000000000000)
Which is approximately 5.5e+22.
Therefore, the largest prime number that divides the quantity is the largest prime number less than 5.5e+22.
It's important to note that this is a very large number and checking for all prime numbers less than it would take a long time. And thus, answer cannot be given.

P is the centroid of ΔXYZ. If XU = 48, what is PU?
The value of the PU in the given triangle is 19.
What is centroid?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.
Given,
'p' is the centroid of triangle XYZ and XU is 57.
Since p is the centroid the 'U', 'V', and 'W' are the mid pint of side'YZ', 'XZ', and 'XY'
from the centroid Theorem, we can write;
XP = 2/3 * XU
plug the values 'XU' in the above equation:
XP = 2/3 *57
XP = 2*19
XP = 38
from figure:
XP + PU = XU
PU = XU - XP
Plug 'XU' and 'XP'
PU = 57 -38
PU = 19
therefore, the PU of the given triangle is 19 units.

a mother is twice as old as her daughter 5 years from now she will be thrice as old as her daughter how old is the mother five years from now
Representation:
equation:
solution:
answer:
Answer:
Let's define the variables:
M = mother's age
D = daughter's age.
"a mother is twice as old as her daughter"
This can be written as:
M = 2*D
"5 years from now she will be thrice as old as her daughter"
(M + 5) = 3*D
We want to know how old is the mother five years from now.
First, our equations are:
M = 2*D
(M + 5) = 3*D
First, we need to isolate one of the variables in one of the equations, because for the solution we want the mother's age, we should isolate the daughter's age.
Let's isolate D in the first equation:
M/2 = D
Now we can replace this in the other equation:
Now we can replace this on the other equation:
(M + 5) = 3*(M/2)
M + 5 - (3/2)*M = 0
-(1/2)*M + 5 = 0
5 = (1/2)*M
2*5 = M = 10
So the mother is 10 years old (this hasn't a lot of sense, maybe there is a wrong number on the question)
and 5 years from now, the mother will be:
10 + 5 = 15 years old.
