Answer:

c

Step-by-step explanation:

How to remember which is which? Well, alphabetically they are:

Complementary add to 90°

Supplementary add to 180°

You can also think:

"C" of Complementary is for "Corner" right angle(a Right Angle), and

"S" of Supplementary is for "Straight" (180° is a straight line)

Or you can think:

when you are right you get a compliment (sounds like complement)

"supplement" (like a vitamin supplement) is something extra, so is bigger

Answer:

i think b but let me known if im wrong

Answer:

a)12

b)1/12

c)4/12

Step-by-step explanation:

a) the coin is a 1/2 and the dice is 1/6 so you times the bottom number and you get 12

b) since that is a exact one way to get it has to be 1/12 chance

c) so to only get a tails it would be 6/12 and less than 5 means you can get 1,2,3, and 4 so that is 4 ways out of 12 ways so its 4/12

Step-by-step explanation:

If u assume x=y=1, then x+y=2 and x^2+y^2=2

And now, xy=1.

Therefore x=y=1.

Let me know, if anyone come with other answers too.

Step-by-step explanation:

(*) x^2 + y^2 - 2xy = 64

<=> (x - y)^2 = 64

<=> x - y = 8 or x - y = -8

(**) x^2 - y^2 = 40

<=> (x - y)(x + y) = 40

Case 1: x - y = 8

(**) <=> 8(x + y) = 40

<=> x + y = 5

we have: x+y = 5 and x-y = 8

--> x = (5+8)/2 = 6.5

--> y = x - 8 = 6.5 - 8 = -1.5

so (x,y) = (6.5 , -1.5)

Case 2: x - y = -8

(**) <=> -8(x + y) = 40

<=> x + y = -5

we have: x + y = -5 and x - y = -8

--> x = [ (-5) + (-8) ]/2 = -6.5

--> y = -5 - x = -5 + 6.5 = 1.5

so (x,y) = (-6.5 , 1.5)

Answer: (x,y) = (6.5 , -1.5) and (-6.5 , 1.5)

I want to say C

Figure jkl is simular to fugure jkl :)

Answer:

Step-by-step explanation:

dollars:                     7.5     ----------------------->    ??

chicken wings         5      ----------------------->     1

to get 1 of 5 we have to divide 5÷5 = 1

so we have to divide the dollars by 5 too:   7.5÷5 = 1.5

None of those are near 36 at all, so none of the above would be your answer.

Answer:

108 liters

Step-by-step explanation:

Given that:

80 drops are there in 5 minutes.

Time to be considered is 4 weeks.

Let us find number drops in 4 weeks.

Number of drops in 5 minutes = 80

Number of drops in 1 minute = [tex]\frac{80}{5}[/tex]

Number of drops in 60 minutes = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex]

Number of drops in 24 hours (60 [tex]\times[/tex] 24 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex]

Number of drops in 28 days (28 [tex]\times[/tex]24 hours OR 60 [tex]\times[/tex] 24 [tex]\times[/tex]28 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex][tex]\times[/tex]28 = 645120

Now, we are given that 60 drops = 10 mL

1 drop = [tex]\frac{10}{60}[/tex] mL

645120 drops = [tex]\frac{10}{60} \times 645120[/tex] =  107520 mL

We know that 1000 mL = 1 Liter

1 mL =  [tex]\frac{1}{1000}[/tex] Liter

107520 mL = [tex]\frac{1}{1000} \times 107520\ L \approx 108\ L[/tex]

So, the answer is 108 Liter.

Answer:

$2,065

Step-by-step explanation:

The computation of the commission earned by Sam is shown below:

For each sale, he gets 7% commission

So,

For $12,000, the commission amount is

= $12,000 × 0.07

= $840

And, for another sale i.e. $17,500, the commission amount is

= $17,500 × 0.07

= $1,225

So, the total commission he earned is

= $840 + $1,225

= $2,065

Answer: f(8) = 9

Step-by-step explanation:

PEMDAS: Solve for parenthesis first.

f(8)= (8-5)^2

(3)^2

Square that, you get 9.

my bad i put the wrong answer sometimes i put the wrong answer and i dont pay attention to it at all

Answer:

The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

Step-by-step explanation:

Originally Triangle has height =3.5cm and width=4cm

Beth enlarged the same triangle by scale of 5 and calculate area of triangle

The area of triangle as given as A= $$\frac{1}{2} \texrm{ (base) (height)}$$

Area of original triangle is A =$$\frac{1}{2}(3.5 \times 4)$$

Since, The triangle is enlarged by scale of 5

New height =3.5x5 = cm and new width=4x5cm

Area of new triangle is

A' = $$\frac{1}{2} (\textrm{new width} ) ( \textrm{new height})$$

A' = $$\frac{1}{2}(3.5 \times 5)(4\times 5)$$

A' = $$\frac{1}{2}(3.5 \times 4)(5^{2})$$

A' = $$A (5^{2})$$

Now, Looking what error beth made is:

Beth found Area of new triangle is A' = $$\frac{1}{2}(3.5)(4)(5)$$

The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

I am stupid too, so forgive me if I am wrong.ಥ_ಥ

I am pretty sure the correct answer is D since 2 can be multiplied by 3 to get 6, and 3 can be multiplied by 3 to get 9. Thus, if the number of guitars is multiplied by 3, the number of amps will always be a multiple of 3.

Answer:

-x-15

Step-by-step explanation:

x-2x-15

1x-2x-15 (if a term doesn't have a coefficient then the coefficient is 1)

(1-2)x-15 (collect like terms by subtracting their coefficients)

-1x-15

-x-15 (when the term has a coefficient of -1, the number doesn't have to be written but the sign remains)

Step-by-step explanation:

Answer:

Primeras urnas = 60 bolsas

Segundas urnas = 140 bolsas

Terceras urnas = 200 bolsas

Step-by-step explanation:

Deje que las urnas se representen de la siguiente manera

Primeras urnas = a

Segundas urnas = b

Terceras urnas = c

Se nos dice en la pregunta

400 bolsas se distribuyen en tres urnas

Por lo tanto,

a + b + c = 400 bolsas ......... Ecuación 1

Por la pregunta sabemos que

1) El primero tiene 80 menos que el segundo

a = b - 80

2) Y este segundo tiene 60 menos que el tercero

b = c - 60

Por tanto, c = b + 60

Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1

a + b + c = 400 bolsas ......... Ecuación 1

b - 80 + b + b + 60 = 400 bolsas

Recopilar términos similares

b + b + b - 80 + 60 = 400 bolsas

3b = 400 + 80 - 60

3b = 420

b = 420/3

b = 140 bolsas

Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas

Dado que a = b - 80

a = 140 bolsas - 80

a = 60 bolsas

Por lo tanto, el número de bolsas en la primera urna = 60 bolsas

Dado que c = b + 60

b = 140 bolsas

c = 140 + 60

c = 200 bolsas.

El número de bolsas en las terceras urnas = 200 bolsas.

Answer:

A) 3<x<13

Step-by-step explanation:

It would be A) 3<x<13.  It can’t be D because if it were equal to 3 or 13, it would be a line, not a triangle.  X must be greater than 3 and less than 13.

I believe that C is correct!

Yep. Answer is C

Actually Welcome to the Concept of the Logical Analysis of pattern.

Since here we can determine it,

It shows that,

8-4 = 4 +6 = 10 and so, on

so,

3rd option is the answer.

--> Subtract 4 , Add 6 , repeat it

Answer:

From 8 to 4, there is a difference of 4, and from 4 to 10 a difference of 6. This continues until 8, and the next in the pattern if plus 6.
