$5 - $1.15 = 3.85
the correct answer is $3.85 which is 3 dollars and 85 cents.
So, I guessing the question is written wrong. The only thing that would make sense is "A carpenter took the following measurements: 3.4m, 10.25m, 20.2m, and 19m. How many SIGNIFICANT FIGURES does the sum of the measurements have?"
1. Add The Measurements

52.85 Has 4 Significant Figures, this is the more precise measurement
HOWEVER, the rules of Significant Figures states that when adding we must put our answer in the same amount of decimal places as the least one in our expression. So 3.4has 1 decimal place, 10.25 has 2, 20.2 has 2, and 19.0 has 1. So we must put our answer only to the tens place and not the hundredth as we have it. OUR SIG FIG ANSWER IS;

This is considered less precise, for example 19 is just saying approximately 19, while 19.0 says this is exactly 19
Answer:
x=34/5 y=6/5
Step-by-step explanation:
so first you need to isolate one variable in one equation
so lets use 3x-12y=6
3x=12y+6
x=4y+2
then, as the name implies, we substitute it into the second equation
3(4y+2)-7y=12
then we simplify
12y+6-7y=12
5y=6
y=6/5
then we plug it in to find x
3x-7(6/5)=12
3x-42/5=12
3x=102/5
x=34/5
check work
3(34/5)-12(6/5)=6
102/5-72/5=6
30/5=6
6=6

$1,600 < y < $2,000 </span>
<span>h = –16t 2 + 64t + 8
since both the launch height and target height are identical we can say height is 0
solve for t
0 = -16t^2 + 64t +8
-8(2t^2-8t-1) =0
divide both sides by -8
2t^2-8t -1 = 0
t = 4.12 and -0.121
since it can't be a negative number:
t = 4.12 seconds ( round off as needed)
