Question:

Correctly complete this sequence: 131, 517, ?, 123

Answer:

The completed sequence: 131, 517, 192, 123

Step-by-step explanation:

Given sequence is 131, 517, ?, 123

Step 1: Now, write the given numbers without any commas as below,

                131517?123

Step 2: Then, split it into two digit numbers as 13, 15, 17, _ _, 23

Step 3: Fill the sequence with the missing two digit odd numbers. So, we can write as below

              13, 15, 17, 19, 21, 23

Step 4: Again, rewrite and form the sequence without any commas.

                    131517192123

Step 5: Place the class after every three digits.

                    131, 517, 192, 123

Step 6: At last, found that the missing number is 192.

This is a simple addition sequence. The next number in the sequence would be 903, resulting from the addition of 386 to the previous term 517. So, the completed sequence is 131, 517, 903, 123.

The sequence in question appears to be a simple addition sequence between consecutive terms. If you subtract the first number from the second number, you get 386 (517-131 = 386). Assuming this addition pattern continues, you can find the next number in the sequence by adding 386 to 517. So, the next number in the sequence would be 903 (517 + 386).

This means the completed sequence should read: 131, 517, 903, 123. Always remember to check the difference between your terms when working with sequences like this one.

Answer:

force = 21 kg m/s^2 = 21 N

Step-by-step explanation:

If an object has mass (m)  3 kg, and its acceleration (a) is 7 m/s^2, its force is given by Newton's second law of motion: Force = M * a

Force = 3 kg * 7 m/s^2= 21 kg * m/s^2

This combinations of units (kg * m/s^2) is defined as Newtons in physics and abbreviated "N".

So we can say that the force on this object is of magnitude 21 N

Answer:

width = (x-1)

Step-by-step explanation:

The volume of the prisms is defined in the problem as

Volume = x^3 + 9x^2 + 6x − 16

Volume  = width*height* length

And we know that,

length = (x+2)

height = (x+8)

We can find the roots of the equation, which happen to be

x = -8

x = -2

x = 1

(See image below)

This means that the volume can be represented as

Volume = x^3 + 9x^2 + 6x − 16 = (x+8)(x+2)*(x-1)

Therefore,

The width = (x-1)

Answer:

4 students would be eligible for the scholarships

Step-by-step explanation:

Final answer:

In a high school with 400 graduating students, only 4 students would be eligible for scholarships that are offered to students in the top 1% of their class by GPA.

Explanation:

To determine how many students from a high school with 400 graduating students would be eligible for scholarships offered to those in the top 1% of their class, we simply need to calculate 1% of 400. Mathematically, this is represented as:

400 students * 1% = 400 students * 0.01 = 4 students

Therefore, in a high school graduating class of 400 students, only 4 students would be eligible for these scholarships based on being in the top 1% of their class according to GPA.

Answer:

The factors of  [tex]2(x+y)^2-9(x+y)-5[/tex] is ((x+y)-5)(2x+2y+1)

Step-by-step explanation:

Given polynomial

=>[tex]2(x+y)^2-9(x+y)-5[/tex]

To Find:

The factors of the polynomial =?

Solution:

Lets assume  k = (x+y)

Then [tex]2(x+y)^2-9(x+y)-5[/tex] can be written as [tex]2k^2-9k-5[/tex]

Now by using quadratic formula

k =[tex]\frac{-b\pm\sqrt{(b^2-4ac}}{2a}[/tex]

where

a= 2

b= -9

c= -5

Substituting the values, we get

k =[tex]\frac{-b\pm\sqrt{(b^2-4ac)}}{2a}[/tex]

k =[tex]\frac{-(-9) \pm \sqrt{((-9)^2-4(2)(-5)}}{2(2))}[/tex]

k =[tex]\frac{-(-9) \pm \sqrt{(81+40)}}{4}[/tex]

k =[tex]\frac{-(-9) \pm \sqrt{(121)}}{4}[/tex]

k =[tex]\frac{-(-9) \pm 11}}{4}[/tex]

k= [tex]\frac{ 9 \pm 11}{4}[/tex]

k =  [tex]\frac{20}{4}[/tex]                         k =  [tex]\frac{-2}{4}[/tex]    

[tex]k_1 =5[/tex]                                      [tex]k_2 = -\frac{1}{2}[/tex]

[tex]2k^2-9k-5= 2(k-5)(k+\frac{1}{2})[/tex]

Solving the RHS we get

[tex]\frac{2}{2}(k-5)(2k+1)[/tex]

[tex](k-5)(2k+1)[/tex]

Substituting k = x+y

[tex]((x+y)-5)(2(x+y+1)[/tex]

[tex]((x+y)-5)(2x+2y+1)[/tex]

Answer:

[tex]V=63,829.92\ cm^3[/tex]

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference is equal to

[tex]C=2\pi r[/tex]

we have

[tex]C=69.08\ cm[/tex]

assume

[tex]\pi =3.14[/tex]

substitute

[tex]69.08=2(3.14)r[/tex]

solve for r

[tex]69.08=6.28r[/tex]

[tex]r=69.08/6.28[/tex]

[tex]r=11\ cm[/tex]

step 2

Find the volume of the cylinder

we know that

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]h=168\ cm[/tex]

[tex]r=11\ cm[/tex]

assume

[tex]\pi =3.14[/tex]

[tex]V=(3.14)(11)^{2}(168)[/tex]

[tex]V=63,829.92\ cm^3[/tex]

Answer:

Step-by-step explanation:

r = 5s + 7

r + s = 25

5s + 7 + s = 25

6s + 7 = 25

6s = 25 - 7

6s = 18

s = 18/6

s = 3 <=== sam has 3 video games

r = 5s + 7

r = 5(3) + 7

r = 15 + 7

r = 22 <=== robert has 22 video games

Answer: 14 butterflies per hour

Step-by-step explanation: "Per hour" means in 1 hour so we can rewrite the given statement using fractions.

42 butterflies over 3 hours = ___ butterflies per hour.

I have attached my work in the image provided.

To find out what goes in the blank, notice that we have a 1 in the denominator of our second fraction. So we want to find a fraction that is equivalent to 42/3 that has a 1 in the denominator.

If we divide the numerator and denominator of 42/3 by 3, we get the equivalent fraction 14/1 or 14 butterflies over 1 hour. So now we have 14 butterflies over 1 hour = ___ butterflies per hour.

Now we can easily see that a 14 must go in the blank which means that the unit rate for 42 butterflies in 3 hours is 14 butterflies per hour.

" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function ⇒ D

Step-by-step explanation:

The form of the linear function is f(x) = mx + b, where

∵ f(x) = 37 x + 20 models the total cost for Rachel to be a member

   at a gym for x months

∵ f(x) = m x + b

∴ m = 37 and b = 20

∵ m represents the rate of change

- That means she must to pay 37 per month for x months

∴ Rachel must pay $37 per month to use the gym

∵ b represents the initial amount

- That means she pays a fixed amount one time

∴ Rachel must pay a $20 membership fee to join the gym

Because a Relation can be represented as a verbal descriptions, graphs, mapping diagrams, equations, list ordered pairs, and tables. Which in this case is an equation so its a RELATION.

A function is a type of relation in which every x-value in the domain is paired with exactly one y-value. Which in this case every x-value is paired with one Y-value.

Area of circular pipe in terms of pi is found as [tex]100 \pi[/tex] square centimeter

Solution:

Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm

We have to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is:

diameter = 20 cm

Let us find the radius

[tex]radius = \frac{diameter}{2}\\\\r = \frac{20}{2} = 10[/tex]

Thus radius = r = 10 cm

The area 'A' of the circular cross-section of the pipe measn we can use the area of circle formula

The area of circle is given as:

[tex]area = \pi r^2[/tex]

Where "r' is the radius of circle

We have to find area in terms of pi

[tex]area = \pi (10)^2\\\\area = \pi \times 10 \times 10\\\\area = 100 \pi[/tex]

Thus area of circular pipe in terms of pi is found as [tex]100 \pi[/tex] square centimeter

36 = 8x

x = 2

Put the value of x = 2 in 19X + 14, and divide that answer by 2, because GF is 2x smaller than AG

19x + 14
