Answer:
The answer to your question is: letter B. 16 days
Step-by-step explanation:
Materials = $3.89 square foot
Day of labor = $121.26
Total $2982.68
Square feet = 252 more than the number of days
Process
materials = days of labor + 252
materials = m
days of labor = d
m = d + 252 (I)
Total Equation
3.89m + 121.26d = 2982.68
3.89(d + 252) + 121.26d = 2982.68
3.89d + 980.28 + 121.26d = 2982.68
3.89d + 121.26d = 2982.68 - 980.28
125.15d = 2002.4
d = 16
Number of days 16.
Answer:
5. A.
6. F
Step-by-step explanation:
5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3
y = 3x + b
using coordinates (-6,3)
3 = 3(-6) + b
b = 21
y = 3x + 21
6. I think F is the right answer
Answer:
-4/5
Step-by-step explanation:
For all points that lie on the y-axis, the x-coordinate is zero.
rules to find :- 1 All non zeroes number are significant
2 if zero proceeding the decimal point also work as non zero figure
3 zero are following the decimal point and proceeding the first non zero digit
4 Zero in between 2 non zero digits are also significant
5 if 1 zero follow the decimal point
790 :- 2 significant figures
0.0391 :- 3 significant figures ( follow 3 rule)
81.05 :- 4 significant figures ( rule 4)
0.000001 :- 1 significant figure
8546 :- 4 significant figures
79.0 :- 3 significant ( rule 5)
