Aeyanna has 16 coins that are dimes and quarters. In
total, the coins have a value of $3.10. How many
dimes does she have? How many quarters does she
have?
Identify your variables:

Answers

Answer 1

Answer:

It’s also worth pointing out that the presentation of the algebraic expressions in coin word problems are a bit different and not so straightforward compared to what we’re used to. For example, instead of saying “the number of nickels is 2 more than the number of dimes“, you’ll often see this expressed in coin word problems as “there are 2 more nickels than dimes“. Both algebraic expressions can be written in an equation as n=d+2n=d+2 but just expressed differently.

Step-by-step explanation:

Tamara has 35 coins in nickels and quarters. In all, she has $4.15. How many of each kind of coin does she have? Right off the bat, the problem gives us two important pieces of information. First, it tells us that there is a total number of 35 coins consisting of nickels and quarters. Secondly, the total value of the coins is $4.15. We need to translate these statements into algebraic equations to find how many nickels and how many quarters she has.

BTW hope this helps

Sharon Fox decided to buy a home in Marblehead, Massachusetts, for $282,000. Her bank requires a 20% down payment. Sue Willis, an attorney, has notified Sharon that besides the 20% down payment there will be the following additional costs:




Recording of the deed $ 37.00
A credit and appraisal report 162.00
Preparation of appropriate documents 55.00

In addition, there will be a transfer tax of 2% of the purchase price and a loan origination fee of 2% of the mortgage amount. Assume a 30-year mortgage at a rate of 10.5%.




a. What is the initial amount of cash Sharon will need? (Do not round intermediate calculations. Round your answer to the nearest cent.)








b. What is her monthly payment? (Do not round intermediate calculations. Round your answer to the nearest cent.)








c. What is the total cost of interest over the life of the mortgage? (Do not round intermediate calculations. Round your answer to the nearest cent.)

Answers

The initial amount of cash that Sharon will need in this scenario will be $67821.20.

How to calculate the payment?

The initial amount of cash will be:

= ($282000 × 20%) + ($282000 × 2%) + ($276360 × 2%) + ($162) + ($37) + $55

= $56400 + $5640 + $5527.20 + $162 + $37 + $55

= $67821.20

Therefore, the the initial amount of cash Sharon will need is $67821.20.

4x+28=12

4x=-16

x=-4

Answer:

4x²+20x+16=0

Step-by-step explanation:

First we can expand the right side:

[tex](2x+4)(2x+7) = 4x^{2} +8x+14x+28[/tex]

Simplify:

[tex]4x^{2} +26x+28[/tex]

Now we can expand the left side:

[tex]3(2x+4) = 6x+12[/tex]

Now we equate both of them to each other:

[tex]4x^{2} +26x+28= 6x+12[/tex]

To make this into a quadratic form we can subtract 6x+12 from both sides:

[tex]4x^{2} +26x+28 - (6x+12) = 6x+12- (6x+12)[/tex]

Simplify

[tex]4x^{2} +20x+16 = 0[/tex]

This is the equation in most simplified version.

You graph the number of times you go to the movies as one variable and the total amount of money you spend on movie tickets as the other variable. What type of slope would you expect the trend line to have?

Answers

Using linear function concepts, it is found that the trend line would be expected to have a positive slope.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, the more times you go to the movies, the more money you are expected to spend, hence the variables are direct proportional and the trend line would be expected to have a positive slope.

Step-by-step explanation:

Angles of a triangle add up to 180. 180-80-20 is 80.

if A and B are two distinct points on the plane then distance between them is
A)zero
B)1
C)negative
D)positive​

Answers

By definition, the distance between two points is always positive, so the correct option is D.

How to get the distance between two points?

Let's say that our plane has rectangular coordinates, so it would be something like a xy-plane.

Each point has 2 coordinates, so we can write:

A = (x₁, y₁)

B = (x₂, y₂)

The distance between the points is given by:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

As you can see, the distance is defined as positive (indifferent of the coordinates of the points).

So the correct option is D, the distance is always positive.

In order to solve this figure, we need to find a useful relationship between the various angles. We can use the straight angle at the upper left vertex of the equilateral triangle.

__

The sum of angles there is ...

  a + 60° +(a/2) = 180°

  3/2a = 120° . . . . . . . . . . subtract 60°, collect terms

  a = 80° . . . . . . . . multiply by 2/3

All triangles are isosceles, because they all have 2 (or more) sides the same length. That means the base angles are half the supplement of the a.pex angle. Of course, adjacent vertices of a rhombus have supplementary angles.
