Answer:
a) rounded to the ones place and 2 significant figures.
b) rounded to tenths place and 1 significant figure.
Step-by-step explanation:
Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.
A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.
B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
Answer:
True
Step-by-step explanation:
The variable overhead rate variance refers to the difference in two variables.
The Variables are
1. The actual variable manufacturing overhead
2. The expected variable overhead given the number of hours worked
Labor rate variance is evaluated by
AH(AR - SR)
AH = actual hours
AR = actual rate
SR = standard rate.
The variable overhead rate variance is also calculated the same way except that it replaces the direct labor rates with variable overhead rates
