Shiloh wants to buy a long lasting candle. Type 1 candle melts by 19.5 cm each hour. Type 2 candle melts by 0.15 inch each minute. Both the candles have the same original height. [1 inch = 2.54 cm Part B: If the original height of the candles was 40 cm, and you checked on its height every 30 minutes after lighting it, describe appropriate scales on the x-axis and y-axis to graph the rate at which the slower candle melts. (5 points

OpenStudy (anonymous):

so, first you need to convert all your measurements to the same scale (metric)

OpenStudy (anonymous):

Cm and inches ?

OpenStudy (anonymous):

so convert the one in inches to cm

OpenStudy (anonymous):

and you'll also want to divide 19.5 by 60 to discover the rate per minute

OpenStudy (anonymous):

then you'll graph according to the points you find when your data is all on the same format

OpenStudy (anonymous):

22.86 cm per hr

OpenStudy (anonymous):

0.325 in per min

How to I find the scales ??

@only_hanaaa

OpenStudy (only_hanaaa):

this is your scale 1 inch = 2.54 cm

OpenStudy (anonymous):

But how do I put it in the form of x and y ? Like for x should I put 15 minutes I'm highly confused . Any help ? @only_hanaaa

OpenStudy (only_hanaaa):

since you already converted your meausments you should prob use x for the time and y for the height

OpenStudy (anonymous):

So can It go by 15 min for x and 6cm for height ? @only_hanaaa

OpenStudy (only_hanaaa):

correct

Could you help with one more Jane poured 12 cups of water into a rectangular container measuring 12 inches by 8 inches by 9 centimeters. [1 cup = 14.44 cubic inches; 1 inch = 2.54 cm] Part A: What is the maximum volume of water that the rectangular container can hold? Show your work. (3 points) Part B: How many cubic inches of water was poured into the container? (3 points) Part C: What was the height of the water in the container? Show your work. (4 points) @only_hanaaa

OpenStudy (anonymous):

I only need part c

OpenStudy (only_hanaaa):

sure, for part c you need to find the height of the water in the container...you need to convert the "12 inches by 8 inches by 9 centimeters" into the cups measurement

OpenStudy (only_hanaaa):

using [1 cup = 14.44 cubic inches; 1 inch = 2.54 cm] conversion

OpenStudy (anonymous):

So 9 cm= 22.86 in

OpenStudy (only_hanaaa):

yes, and now you convert the 22.86 in into cups using 1 cup = 14.44 cubic inches

OpenStudy (anonymous):

1.58 cups ??

OpenStudy (only_hanaaa):

yes

OpenStudy (only_hanaaa):

now you need to convert the other measurements into cups and then you add them up, and you get your height of water in cups

OpenStudy (anonymous):

So 2.96 ?? @only_hanaaa

OpenStudy (only_hanaaa):

yep

OpenStudy (anonymous):

Thanks

yw :)
