Answer:

After the 8th city is built there will be 28 roads between the cities

Step-by-step explanation:

The given parameters are;

The number of cities initially on the island = 7 cities

The number of roads between each 2 cities = 1 road

Therefore, we have the number of roads between the 7 cities are;

7 cities taking 2 at a time = ₇C₂

[tex]_7C_2 = \dfrac{7!}{(7 - 2)!\cdot 2!} = 21[/tex]

The initial number of roads between the 7 cities = 21 roads

The number of roads, 'n' there will be after the 8th city is built is therefore;

[tex]n = _8C_2 = \dfrac{8!}{(8 - 2)!\cdot 2!} = 28[/tex]

The number of roads there will be after the 8th city is built, n = 28 roads.

33% = 33/100

Answer:

90

Step-by-step explanation:

its half

Answer:

2/11

4/11

6/11

Step-by-step explanation:

probability the letter B = number of times b appears in the word / total number of alphabets

total number of alphabets = 11

number of times b appears in the word = 2

2/11

a vowel = total number of vowels in the word / total number of alphabets

vowels include = a,e,i,o,u

vowels in the word = a, o, i

total number of vowels in the word = 4

4/11

A letter before M in the alphabet = total number of alphabets before m in the word  / total number of alphabets

letters before m = A, B, C, D, E, F, G, H, I, J, K, L

letters before m in the word = b,a, i , l

number of words before m = 6/11

Answer:

Linear pair angle of 136 degree =180-136

=44

Therefore angle y is alternate angle of 44

Therefore angle y=44

Answer:

44

Step-by-step explanation:

180 - 136 = 44

Answer: 4

Step-by-step explanation:

Answer:4

Step-by-step explanation: for example, you have 1/4 if you double that you get 2/8, triple it would be 3/12, next would be 4/16

Answer:

C) 17.1 square units

Step-by-step explanation:

Use Heron's formula to calculate the area of the triangle:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]  where  [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:

[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]

Therefore:

[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]

[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]

[tex]Area = \sqrt{296.45}\\[/tex]

[tex]Area = 17.2[/tex]

Therefore, the closest answer choice is C) 17.1 square units

Answer:

C. 1/4

Step-by-step explanation:

2 * 1/2^3t

substitute 1 for t so it would be:

2 * 1/2^3 = 2 * 1/8 = 2/8 = 1/4

Answer:

Yes it is a function.

Step-by-step explanation:

It is given that James raises chickens in his farm. and the chicken laid eggs on each day. James keeps a track of the number of eggs that his chicken laid at the end of each week.

This is a function because according to the definition of a function, if each of he input corresponds to exactly one output, then that relation is called as a function.

In this case, every week the chickens lay different number of eggs. So every week corresponds to the different number of eggs laid by the chicken. So it is a function.

Answer:

Yes it is a function because there is a domain/Input for each Range/Output

Answer:

  3x +2y +24 = 0

Step-by-step explanation:

In general, the equation of a perpendicular line can be found by swapping the coefficients of x and y, then negating one of them. The value of the constant will be what is required to make the line pass through the given point.

The equation will be of the form ...

  3x +2y +c = 0

At the given point, (x, y) = (-6, -3), we have ...

  3(-6) +2(-3) +c = 0 . . . . substitute the given point coordinates

  -18 -6 +c = 0 . . .simplify

  c = 24 . . . . . . . . add 24

The general-form equation for the line is ...

  3x +2y +24 = 0 . . . . . shown in blue in the attachment

Answer:

4 small

8 large

Step-by-step explanation:

s - small mug

l - large mug

Yesterday she had 200 at start of day

at end of day 188 left, so she sold 12 mugs

(1)   s + l = 12

(2)  2.50s + 5.75l = 56.00

Solve for l in (1)

l = 12 - s

substitute in l = 12 - s into (2)

2.50s + 5.75(12-s) = 56.00

2.50s + 69.00 - 5.75s = 56.00

-3.25s + 69.00 = 56.00

-3.25s = -13.00

s = 4

to find l substitute s = 4 into (1)

4 + l = 12

l = 8

Answer:

y = 3x

Step-by-step explanation:

to get y we multiply x by 3 so we have that y = 3x.

12. i dnt know

13.9/6+3/6x=y or 1.5+0.5=y

Step-by-step explanation:

10. starts at 50, goes up by 20 per week

11. starts at 300, goes down 40 per week

13.

9+3x=6y

9/6+3/6x=y or 1.5+0.5=y

Khan Academy told me

Answer:

10 cent coins = 43

Step-by-step explanation:

x = 10 cent coins

y = 5 cent coins

x + y = 157, then y = 157 - x

$10 = 1000 cents

0.10x + 0.05y =1000

substitute for y:

0.10x + 0.05(157 - x) = 1000

0.10x + 7.85 - 0.05x = 1000

combine like terms:

0.05x = 2.15

x = 43

y = 114
