Answer:

whoever the smallest dwarves are

Step-by-step explanation:

the smaller you are, the more of a dwarf you are

Answer: I'm not positive but the answer may be 28

Step-by-step explanation: 7 dwarves x 4 beds = 28 possibilities

Answer:

It is also B again. Your welcome

Answer:

It is B

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

Use a proportion

[tex]\frac{3}{8}[/tex]=[tex]\frac{x}{48}[/tex]

8*6=48

So if we multiply 3*6, we get how many liters it takes to serve 48 people

3*6=18

The answer would be 18 L

You do this by doing 48/8= 6

The reason you do 48 / 8 is because you you want to find out how many liters you need so if a 3L serves 8 people you would have to divid 48 into 8. (hope that makes since)

6 x 3 = 18L

Then take the 6 and times that by the 3 getting a total of 18 liters

(Hope this makes since :D)

Answer:

[tex]x \in \varnothing[/tex]

Step-by-step explanation:

[tex]3x^{2} -5x+4=0\\ \Delta = \frac{-5^{2\pm \sqrt{5x^{2} -48} } }{6} =\frac{25\pm \sqrt{-23}}{6} \\ \Rightarrow x \in \varnothing \:(can't\: take\: square\: root\: of\: negative\: number)[/tex]

Answer:

yeah she is

in y = m*x + b

b is the initial value or the y-intercept.

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

Answer:

Yep!

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

We first write out $17,500 as a multiplication to 5%

New price = 17500 x 1.05 = 18375  = $18,375

18375-17500 = 875

We then work out the tax on just the mark up of $875 increase

20% mark up = 875 x 0.20 = 175

18.375+175 = 18550

= $18,550 charge to be considered for 5%

However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050

=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500

tax he paid inclusive or non inclusive would be the same.

= $3500

10% of this = 3500 x 0.10 = 350  

18550+350 = 18,900

Therefore it is not dishonest if mentioned in the terms and conditions.

We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

Answer: A

Step-by-step explanation:

Answer: y= -277

Step-by-step explanation:

First substitute x for 13

y= -160- 9(13)

Then multiply -9 and 13

y= -160 -117

y= -277

Answer:

-43

Step-by-step explanation:

-160-9(-13)

-160-(-117)

-160+117

-43

2nd answer : 6[tex]\sqrt{3}[/tex]

Step-by-step explanation:

144-36=108

[tex]\sqrt{108)=[/tex] 6[tex]\sqrt{3}[/tex]

2  1/5x * 1 7/10 y  *  4  3/5 x 1 7/10  (* 7 4/50)

Finds the answer  

10 6/50x  *  7  41/50y   (* 7/4/50)  = 56

79 13/100  (* 7 4/50)  = 56

560  = 56 (10x)

x = 5 6/10

7 (y) = 56 (7y)

8 = 56/7  (y)

y = 8

x = 5 6/10

6/10 of 560  = 336  

336/60 = x

336/60 = 5 6/10

Answer:

7

Step-by-step explanation:

Calculate and sum up the first three terms.

We get:

4[ (1/2)^(1-1) + (1/2)^(2-1) + (1/2)^(3 - 1) ], OR

4[ 1               + (1/2)                + (1/2)^2 ], or

4[1 + 1/2 + 1/4}  = 4[7/4] = 7

Answer:

339.3 cm^3

Step-by-step explanation:

V=πr2h=π·62·3≈339.29201

Answer: 15.64 in exact form, and 16 as an estimate.

Answer:

B

Step-by-step explanation:

Square root both sides and you get x = plus or minus 6, because 6*6 = 36 or -6*-6 = 36.

Answer:

(8)x(15)= 120

Step-by-step explanation:

Answer:

Step-by-step explanation:

(10-2)×(8+7) can be simplified to (8) × (15) = 120.

Another way of doing this problem is to apply the distributive property:

(10-2)×(8+7) = 80 + 70 - 16 - 14 = 150 - 30  =  120

Answer:

1/8

Step-by-step explanation:

1/4= 2/8 ( multiply numerator and denominator by 2)

3/8-2/8

3-2= 1

1/8

Answer:

52

Step-by-step explanation:

sorry if it's wrong

Hello there!

A would be the correct answer since 10 divided by 5 equals 2 and so it would be 2x.

B is wrong since it has a constant of proportionality equal to 1.

C is wrong since it has a constant of proportionality equal to 1/2.

D is wrong since it has a constant of proportionality equal to 11.

Answer:

A

Step-by-step explanation:

The equation of proportional quantities is

y = kx ← k is the constant of proportionality

A

y = [tex]\frac{10}{5}[/tex] x = 2x ← with k = 2

B

y = [tex]\frac{2}{2}[/tex] x = x ← with k = 1

C

y = [tex]\frac{2}{4}[/tex] x = [tex]\frac{1}{2}[/tex] x ← with k = [tex]\frac{1}{2}[/tex]

D

y = [tex]\frac{22}{2}[/tex] x = 11x ← with k = 11

Thus A is the required equation

Answer:

Step-by-step explanation:

a.

y=0.75x

y-y1=(y2-y1)/(x2-x1)×(x-x1)

y-3=(6-3)/(8-4) (x-4)

y-3=3/4(x-4)

y-3=3/4 x-3

y=3/4 x-3+3

y=3/4 x

if y=f(x)

f(x)=0.75x

c.

f(12)=0.75×12=9$

Answer:

B. (1,0)  (2,0)  (3,0)

C. (0,4) (0,-4) (6,0)

Step-by-step explanation:

Letter b is asking for points inside of the shaded portion, and letter c is asking for the points that make up the triangle.

Answer:

x = -1 and x = 4

Step-by-step explanation:

Answer: (x,y) = (2, -1.5)

Step-by-step explanation:

6x + 5y = 4.5

y = 3+2/3y

= 6 (3+2/3y) +5y = 4.5

y = -1.5

For x, x = 3 + 2/3 (-1.5)

x = 2

Step-by-step explanation:

5/3890 = 778

then check if its right

5*778 = 3890

(m=778)

Answer:

sqroot(9) - 7 = -4

sqroot(10) - 7  = -3.838

sqroot(11) - 7 = -3.683

sqroot(12) - 7 = -3.536

It isd not equal to -4 but pretty close so I am thinking that B is the right choice.

Answer is B

Answer:

64 degrees

Step-by-step explanation:

Angles in a triangle add up to 180

87 + 29 = 116

Final angle must be 180 - 116 = 64

Answer:

Hello,

B) 64

Step-by-step explanation:

29 + 87 + X = 180

X = 180 - 29 - 87 = 180 - 116 = 64
