A linear function can be used to estimate the decrease in snowfall measured since 1920 the decrease in the annual snowfall has been an average of 0.24 in per year let X represent the number of years since 1920 when the measurements began and let y represent the annual snowfall the initial measurement in 1920 was 48.6 in using the average change and initial measurement which is the best estimate of the annual snowfall and the 78th year after records were kept round to the nearest hundredth of a 15.84 in B 27.72 in C 29.88 in D 67.32 in

C- 29.88

Step-by-step explanation:

i did it on the edge test

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
