Answer:

18 students took the bus to school.

Step-by-step explanation:

If 1/4 of the students walked, that leaves 3/4 of the students who did not walk. That leaves 22.5 students. Out of these students 22.5, 4/5 of them take the bus, and 4/5 of 22.5 is 18.

Answer:

The value of x is 20 ⇒ A

Step-by-step explanation:

When a line intersects two parallel lines, then some pairs of angles are formed

In the given figure

∵ Lines l and m are parallel

∵ They are intersected by a line

∴ The angles of measures (3x + 5)° and 65° are alternate interior angles

→ That means they are equal in measures

∵ Alternate interior angles are equal in measures

∴ (3x + 5)° = 65°

→ Subtract 5 from both sides

∵ 3x + 5 - 5 = 65 - 5

∴ 3x = 60

→ Divide both sides by 3

∴ x = 20

∴ The value of x is 20

Step-by-step explanation:

Answer:

2205

Step-by-step explanation:

Letter 1 is a consent, so there are 21 choices for the letter (all 21 consonants).

Letter 2 is a vowel, so there are 5 choices (all 5 vowels).

Letter 3 is a consent so there are 21 choices (all 21 consonants).

One would have to do 21 * 5 * 21 to find the number of combinations which fit these criterias.

21 * 5 * 21

= 2205

This is disregarding all the other rules of English grammer and word strucutre, so the total amount of combinations that can be found would include nosensical words. The total number of words would also include repeating consonants, so a consonant can appear twice in a combination, and some combinations might repeat.

Answer:

The elevation is [tex]32.3^{o}[/tex].

Step-by-step explanation:

The home of the meerkat is 8 feet below the surface. So that the root of the stump would not be in his path, he dug 15 feet lower.

This can be represented by the sides of a right angled triangle. Applying the appropriate trigonometric function, let the elevation be represented by θ.

Then,

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

        = [tex]\frac{8}{15}[/tex]

Sin θ = 0.5333

⇒ θ = [tex]Sin^{-1}[/tex] 0.5333

      = 32.287

θ = [tex]32.3^{o}[/tex]

The elevation of the meerkat is [tex]32.3^{o}[/tex].

Answer:

Answer:

[tex]\frac{2+\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Using the product to sum formula

sinxcosy = [tex]\frac{1}{2}[/tex] [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + [tex]\frac{\sqrt{3} }{2}[/tex]

= [tex]\frac{2+\sqrt{3} }{2}[/tex]

Answer:

  p(x) = x^3 +x^2 -82x +80

Step-by-step explanation:

If a polynomial function has a zero at x=a, then (x -a) is a factor. Your list of zeros means the factors are ...

  p(x) = (x -8)(x +10)(x -1) . . . . . . . . factored form

When this is multiplied out, it becomes ...

  p(x) = x^3 +x^2 -82x +80 . . . . . . standard form

_____

The factored form can be multiplied out using the distributive property.

  = ((x(x +10) -8(x +10))(x -1)

  = (x^2 +10x -8x -80)(x -1)

  = (x^2 +2x -80)x -(x^2 +2x -80)

  = x^3 +2x^2 -80x -x^2 -2x +80

  = x^3 +x^2 -82x +80

Answer:

At the maximum Josie can be 17 games.

Step-by-step explanation:

Given that:

Total money available with Josie to be spent at a festival = $30

Entry ticket for the festival = $5

Ticket for each game = $1.40

To find:

The inequality to represent the situation and the number of games that Josie can play.

Solution:

Ticket for 1 game = $1.40

Let [tex]n[/tex] number of games can be played.

So, Ticket for [tex]n[/tex] games = $1.40[tex]n[/tex]

Total money spent = $1.40[tex]n[/tex] + $5

It is should be lesser than or equal to $30.

[tex]1.40n + 5 \leq 30\\\Rightarrow 1.40n \leq 25\\\Rightarrow n \leq 17.8[/tex]

Therefore, at the maximum Josie can be 17 games.

Answer:

3

Step-by-step explanation:

15g

g=1/5

15×1/5

15/1×1/5=3

Answer:

3

Step-by-step explanation:

This is the answer because:

1) We have to substitute the value into the equation:

15(1/5)

2) Next, we have to mutiply 15 and 1/5 together since the g is just a variable that is supposed to be mutiplied with 15:

15(1/5) = 15/5 = 15 ÷ 5 = 3

Therefore, the answer is 3.

Step-by-step explanation:

6G (sixth-generation wireless) is the successor to 5G cellular technology -- 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency.

Answer:

Yes

Step-by-step explanation:

The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).

The number of hours worked is [tex]x[/tex] and the money earned is  [tex]y[/tex].

Let us divide the values of [tex]y[/tex] by [tex]x[/tex]

[tex]\dfrac{72}{6}=12[/tex]

[tex]\dfrac{96}{8}=12[/tex]

[tex]\dfrac{66}{5.5}=12[/tex]

[tex]\dfrac{108}{9}=12[/tex]

[tex]\dfrac{84}{7}=12[/tex]

The fuction which defines the above ordered pairs is [tex]y=12x[/tex]

It can be seen that the amount of money earned is 12 times the number of hours worked.

So, per hour Jerry earns 12 dollars.

Hence, the ordered pairs are relation.
