PLEASE HELP!!!!!!!Fan+medal See pic b and c

OpenStudy (jekdidkdjrjrjjr):

Pic

OpenStudy (jekdidkdjrjrjjr):

pic idk if this helps

OpenStudy (mathstudent55):

Where's the rest of the problem?

OpenStudy (jekdidkdjrjrjjr):

um there

OpenStudy (jekdidkdjrjrjjr):

That circle thing

OpenStudy (jekdidkdjrjrjjr):

oh wait

OpenStudy (jekdidkdjrjrjjr):

PIC

OpenStudy (jekdidkdjrjrjjr):

That

OpenStudy (jekdidkdjrjrjjr):

I have like a bunch of questions that need to be answers and medals to give so like

OpenStudy (jekdidkdjrjrjjr):

Answered*

OpenStudy (mathstudent55):

I see the three targets. That is good. There is still info missing. Are we told that each toss will hit the rectangular background for sure, and we need to find the probability of hitting the inner target once we know the rectangular outer target was hit? Where is the rest of the problem? The first pic starts in part b. Is there a part a, and also some text before part a?

OpenStudy (jekdidkdjrjrjjr):

THIS

OpenStudy (jekdidkdjrjrjjr):

A, b c and d

OpenStudy (mathstudent55):

Did you get part a.?

OpenStudy (jekdidkdjrjrjjr):

I mean I haven't answered it yet

OpenStudy (mathstudent55):

Let's start with part a. For each target, you need to calculate two things. 1. The area of the rectangular board. 2. The area of the hole. They tell you the rectangular boards are all the same, so you only need to calculate the area of the rectangular board once.

OpenStudy (jekdidkdjrjrjjr):

okay

OpenStudy (jekdidkdjrjrjjr):

you're doing the calculating right?

OpenStudy (mathstudent55):

Let's start with part 1. above. What is the area of the outer rectangular board? The length is 12x + 24 inches, and the width is 20 inches.

OpenStudy (jekdidkdjrjrjjr):

Right

OpenStudy (mathstudent55):

You need the area of a rectangle, and you are given its length and width. Find the area. \(A_{rectangle} = length \times width\)

OpenStudy (jekdidkdjrjrjjr):

What's the area?

OpenStudy (mathstudent55):

That's what you need to do. I showed you the length and width, and the formula for the area of a rectangle. Now you find the area.

OpenStudy (jekdidkdjrjrjjr):

ya idk

OpenStudy (mathstudent55):

Since the length is 12x + 24, and the width is 12, you multiply them together to get the area. \(A_{rectangle} = 20(12x + 24)\) That is the areal of the outer rectangular target in all three cases.

OpenStudy (jekdidkdjrjrjjr):

So that's the answer?

OpenStudy (mathstudent55):

Now for each part, we need the area of the hole.

OpenStudy (mathstudent55):

I have no idea what the answer is. There is a lot of calculation needed here. how about you do some of it?

OpenStudy (jekdidkdjrjrjjr):

I'm like really bad at this though

OpenStudy (jekdidkdjrjrjjr):

there's also questions e and f btw

OpenStudy (mathstudent55):

Now find the area of the small rectangular hole of Board 1, then find the area of the circular hole of Board 2, then find the area of the triangular hole of Board 3.

OpenStudy (jekdidkdjrjrjjr):

mhm

OpenStudy (jekdidkdjrjrjjr):

E and f

OpenStudy (mathstudent55):

This question needs a lot of time. I really have to go. My suggestion is for you to find a tutor who can help you in person. You need to learn the basics, such as finding the area of a rectangle.

OpenStudy (jekdidkdjrjrjjr):

dude.

OpenStudy (jekdidkdjrjrjjr):

u can't just tell the the answer like tf

OpenStudy (mathstudent55):

I need time to calculate it and don't have time now. This is not the kind of problem you can just look at and spit out an answer. This takes calculating areas which are polynomials, then dividing polynomials, then multiplying rational expressions together.

OpenStudy (mathstudent55):

Sorry, but gtg.

OpenStudy (jekdidkdjrjrjjr):

thanks byeee
