Harry parks his toy cars. he has less than 100 cars. When he parks them in groups of three, there will be two left, when he parks them in groups of four, there will be two left and when he parks them in groups of 5, there will be two left. How many will be left if he parks them in groups of seven? What method do you use here?

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

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)

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:

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

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.

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.

Answer:

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:

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.

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:

11

Step-by-step explanation:

I’m pretty sure. Just add it

Answer:

11

Step-by-step explanation:

Absolute value only applies to negative numbers. It will make negative numbers positive. As you can see in the problem, they are asking for the absolute value of positive numbers, so you can ignore the absolute value signs and add normally.

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

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:

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

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)
