Question

The perimeter of this rectangle is?

Answer 1

I'm pretty sure it's 130 in but just making sure.

Answer 2

46 inches? all you have to do is multiply the sides you're given by two and add them together

2*10=20
2*13=26
20+26=46

Answer 3

how are you getting 130?

Answer 4

remember that when you try to find the perimeter of a rectangle the formula is 2*length+2*width

Answer 5

i multiplied the two cuz i always thought it was l(w) but i guess not here

Answer 6

and they wanted units so how do i find that

Answer 7

length*width is for the area of a square/rectangle

Answer 8

since a rectangle has four sides you add each side length to get the perimeter

Answer 9

oh i got area and perimeter backwards then

Answer 10

for units its area so then it would be 130. right?

Answer 11

its easy to confuse them, try to write the formulas down in a notebook in order to easily access them when needed

Answer 12

yeah i just did :)

Answer 13

good :) good luck to you with your math

Answer 14

units means area though right? and thanks :P

Answer 15

units means what type of units you are using for the measurement of your perimeter, meters, feet, inches, millimeters, centimeters, kilometers, etc.

Answer 16

oh haha blonde moment thank you

Answer 17

no problem

Answer 18

I really need help with a question but no one seems to be responding, can someone help me?

Answer 19

I might be able to, what's the question

Answer 20

what question?

Answer 21

i only have a little bit of time, so i may or may not be able to help

Answer 22

A scooter was purchased for $1,000, the value depreciates at an annual rate of 15%. Write an exponential formula and graph the function. Then using the graph determine how long it will take for the value to fall below $100

Answer 23

I already found that the formula is V(1)=1000(1-0.15)^t but I cant find the value of t

Answer 24

Hold on just a minute

Answer 25

*V(t)=1000(1-0.15)^t not V(1)

Answer 26

You need to graph that, right?

Answer 27

Or have you already

Answer 28

yeah but i dont have a graphing calculator and wolfram alpha doesnt give the right graphing points

Answer 29

well for exponential equations the base has to be the same. So does the v equal 1000? If yes then you can pretty much solve from there by setting them equal to each other

Answer 30

then one you find t just plug it in

Answer 31

The question is asking at what point will the value of the scooter cost $100, so basically i just need to graph it, thank you for your help though :)

Answer 32

oh i started overthinknig im sorry lol

Answer 33

its okay haha, its confusing because i keep getting an answer thats around 15.35 but none of the answers match it

Answer 34

Have you eliminated any answers?

Answer 35

yeah i think the answer is about 14.2 years, thank you for helping me hahaha i bumped my question to the top about five times and no one else would help me

Answer 36

I got 15.7 so I'm probably not the best help im sorry (/.\)

Answer 37

thats about the same answer that i kept getting so i just found the closest number to match my answer, i hate math sooooo much

Answer 38

it can definitely get confusing.
