Evgesh-ka [11]

Answer:

Hello! I am also having trouble in algebra! From what I can see so far this is what the problem should look like...

Step-by-step explanation:

A. Yes, it s a linear function because it matches the equation y=mx+b

B. The domain is 1, 2, 3 , 4, and 5. This is because there are 5 services you can choose from. The domain is discrete because you can't have half a service.

C. Because I'm also doing this book (I'm in Algebra 1 in 8th grade), I'm also just learning this! So sorry, but I don't know how to solve this one either... can someone please help?

Thanks! Also, just a tip, if you're having trouble ever again go to slader.com where they have all the answers to any textbook. They also have really good explanations! However, for this one, I didn't understand it on slader so I came on here! Good luck and if anyone can help with C that would be much appreciated.

Although we round it to 24 hr, the actual length of a day is 23 hr, 56 min, and 4.2 sec. how many seconds are there in an actual
Andrej [43]

Answer:

86,164.2 seconds

Step-by-step explanation:

There are 60 seconds in a minute, 60 minutes in an hour. Every hour has 3600 seconds. Multiply that by 23.

23×3600=82,800

multiply 60 by 56 for the seconds in the 56 minutes.

60×56=3360

add 82800+3360+4.2= 86,164.2

Brian is buying gifts bags for all of the students in his class. The graph shows the relationship between the number of bags and
noname [10]

An equation that relates the number of bags, x, to the cost, y is <u>y = 5x.</u>

<h3>What is an equation?</h3>

An equation is a mathematical statement that claims that the two sides are equal.

An equation involves two or more variables that require some mathematical operations to obtain their equivalent value.

Therefore, an equation contains numbers, variables, and operators, which show a value after the mathematical operations.

<h3>Data and Calculations:</h3>

Let the number of bags for the class = x (number of students)

Let the unit cost of a bag = $5

Let y = the total cost

Equation, <u>y = 5x</u>

Thus, an equation that relates the number of bags, x, to the cost, y is <u>y = 5x.</u>

If triangle ABC is similar WXY write a proportionality statement for the ratio of the sides of the triangle
Serjik [45]

There are many ways to answer this. Here is one answer shown below

AB/WX = BC/XY

On the left side is the ratio of AB over WX. These two sides are the bottom horizontal portions of the triangles. This is a visual indication that they correspond to one another. More concrete proof of this is that AB and WX are the first two letters of the sequences ABC and WXY respectively. The order is very important to help establish pairs like this.

On the right side of that equation above, we have BC and XY as the diagonal sides on the right part of each triangle. They are the last two letters of ABC and WXY respectively, which is a non-visual way to prove these two sides correspond.

It might help to line up ABC over top WXY so you can pick out the corresponding sides. I show this in the attached image below.
