Step-by-step explanation:

its half

Answer:

9. slope: 1/2 y-int: -4

10. y=20x+50

11. y=-40x+300

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

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:

i just did this problem its 24,880

Step-by-step explanation:

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:

b= -11/12

Step-by-step explanation:

- 10 + 4(3b+10) = 19

-10 + 12b+40 = 19

40-10+12b=19

30+12b=19

-30          -30

12b= -11

/12     /12

b=  -11/12

Answer:

(a) The area is 0.03 square miles

(b) The population density is 12000 people per square miles

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Area of Orchid Hill (in square miles)

The dimension of the neighborhood is 4 blocks by 3 blocks

Since each block are of the same dimensions

The area is calculated as:

[tex]Area = 4blocks * 3 blocks[/tex]

If [tex]20\ blocks = 1\ mile[/tex] then:

[tex]1\ block = \frac{1}{20} mile[/tex]

[tex]1\ block = 0.05mile[/tex]

So, we have:

[tex]Area = 4blocks * 3 blocks[/tex]

[tex]Area = 4 * 0.05 * 3 * 0.05[/tex]

[tex]Area = 0.03mi^2[/tex]

Solving (b): The population density of the neighborhood as people per square mile

From the question, we have:

[tex]People = 360[/tex]

[tex]Area = 0.03mi^2[/tex] --- calculated

So, the population density is:

[tex]Density = \frac{People}{Density}[/tex]

[tex]Density = \frac{360}{0.03}[/tex]

[tex]Density = 12000[/tex]

Answer:

51

Step-by-step explanation:

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:

Answer:

5/12, 6/12 OR 1/2, 4/12 OR 1/3, 9/12 OR 3/4

Step-by-step explanation:

Answer:

(B) $152.50

Step-by-step explanation:

Friday: 5 hours x $7.50 per hour = $37.50

Saturday: 6 hours x $7.50 per hour = $45

Sunday: 4 hours x $7.50 per hour = $30

$40 + $37.50 + $45 + $30 = $152.50

I would have (B) $152.50 in total.

Hopefully this helps :3 sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3

Answer:

True

Step-by-step explanation:

[tex] \sqrt{144} [/tex]

is a rational number.

It is also a perfect square which means it is an integer.

:)

Answer:

Step-by-step explanation:

True.  √144 = 12 (an integer) or 12/1, which is rational.

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:

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.

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:

Answer:

180

Step-by-step explanation:

beacause if you did

Answer:

V = 796 7/8 ft^3

Step-by-step explanation:

The storage unit has a rectangular shape.

Thus, the volume is V = (area of floor)(height)

                                  V = (106 1/4 ft^2)(7 1/2 ft)

                                   V = 796 7/8 ft^3

Converting 106 1/4 ft to 106.25 makes it easier to use a calculator here.  Same with 7 1/2 ft:  7.5 ft

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
