 Part A Question Create An Equation From The Model That Describes The Relationship Between The Weights

Answers

Answer 1

Answer:

steps below

Step-by-step explanation:

3+2y = 2+4y

2y = 1

y = 1/2

Is it correct?

Answer 2

Answer:

On the left side, there are two large weights of mass y and three small weights of mass 1. Represent this side with the expression 2y + 3.

On the right side, there are four large weights of mass y and two small weights of mass 1. Represent this side with the expression 4y + 2.

The scale is balanced, so there is equal weight on each side. We can describe the relationship between the weight on each side of the scale using the equation 2y + 3 = 4y + 2.

De enero a junio, 46200 inmigrantes solicitaron la ciudadanía. Durante este mismo período el año pasado, se postularon 120000 inmigrantes. ¿Cuál es el porcentaje de disminución?

Answers

Usando el concepto de porcentaje, se encuentra que el porcentaje de disminución es de 61.5%.

El porcentage de disminución es la disminución multiplicada por 100% y dividida por la cantidad inicial.

Disminución de 120000 imigrantes para 46200 imigrantes, entonces:

[tex]P = \frac{(120000 - 46200)}{120000} \times 100\% = 61.5\%[/tex]

El porcentaje de disminución es de 61.5%.

About how many years did it take to pay off this account if...
Principal = $1582
Rate = 2.5%
Interest = $79.10
Answer:

Answer:

2 years

Step-by-step explanation:

Simple Interest=P×r×n

where:

P=Principal amount

r=Annual interest rate

n=Term of loan, in years

79.10/(1582*0.025)=x

x=2 years

Draw a possible function that satisfy the given domain and range

Answers

9514 1404 393

Answer:

  see attached.

Step-by-step explanation:

Your graph demonstrates a possible function, but it has the domain and range swapped.

__

The domain is the horizontal extent, so your line must end at x=-9 on the left and x=6 on the right.

The range is the vertical extent, so the function must extend from -4 at the bottom to +8 at the top.

The attachment shows a linear function with those characteristics.

Hope this helped you- have a good day bro cya)

The factors of 20 that are not also factors of 12​ are 5 and 10.

What is a factor?

A factor exists as a number that divides the assigned number without any remainder. The factors of a digit can either be positive or negative. The factors of any number exist as finite.

To estimate the factors of 20 and 12

To estimate the factors of 20

Find the prime factors of 20 are 2, 2, and 5.

Multiply the prime factors of 20 are 4, 10.

Adding prime factors 2, 5

Add 1 and the number 20 itself 1, 20.

The factors of 20 are 1, 2, 4, 5, 10, and 20.

To estimate the factors of 12

Find the prime factors of 20 are 2, 2, and 3.

Multiply the prime factors of 12 are 4, 6.

Adding prime factors 2, 3

Add 1 and the number 20 itself 1, 12.

The factors 12 are 1, 2, 3, 4, 6, and 12.

Answers

Step-by-step explanation:

0,06x + 0,1(20000-x) = 0,09(20000)

0,06x + 2000 - 0,1x = 1800

-0,04x = -200

x = -200 /(-0,04)

x = 5000

therefore,

for 6% interest => total invest =$5000

Given A and B, use your knowledge of sets to determine which one of the following numbers is not in
AUB.
A = {-10, 8, 12, 26, 29}
B = {-8, - 1,5, 26, 36}


A.18
B. -10
C. 26
D. 36
E. None of the above

Answers

Answer:   A.  18

===========================================================

Explanation:

The set A U B represents the list of items that are either in set A, set B or both sets at the same time. The "U" is the union symbol.

Set A U B looks like this

A U B = {-10, 8, 12, 26, 29,   -8, - 1,5, 26, 36}

I basically started with set A, then tacked on the stuff in set B shown in bold.

From here, we toss out the duplicate item 26 and we can optionally sort the set

A U B = {-10, -8, -1, 5, 8, 12, 26, 29, 36}

We see that the number 18 is not in this final set, which is why choice A is the answer.

--------------------

Put another way: the number 18 is neither in set A nor set B, so it cannot be in set A U B.

Something like -10 is in set A, so it's going to be in set A U B as well. We can rule out choice B for this reason. Choices C and D follow a similar idea as choice B.

y=(-3/5)x

Step-by-step explanation:

5x-3y=20

-3y=-5x+20

y=(5/3)x-(20/3)

perpendicular lines have opposite reciprocal slopes

Answer:

Perpendicular line is y = -3/5 x - 20/3

Step-by-step explanation:

First subtract 5x to move it to the other side. Now you have -3y = -5x + 20 . Next divide -3 on both sides to get y by its self. Now you have

y = 5/3 x - 20/3.

To find the perpendicular line, just remember that slope will be opposite. Look at the graph, I did for you above.⤴⤴⤴
