Answer:
Option C
Z=8
Step-by-step explanation:
5z-8=32
Rearranging the equation
5z-8+8=32+8
5z=40
Z=40/5
Z=8
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:
Small numbers:
However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
Answer:
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48
Step-by-step explanation:
Custodian at Movie Theater
pay:$9.95
per hours:
15.25 hours per week
How much do they make in
1) a- week
1 week = 15.25 hours
Hence,
1 hour = $9.95
15.25 hours = x
Cross Multiply
x = 15.25 × $9.95
x = $151.7375
Approximately = $151.74
2) A month
There are 4 weeks in a month
1 week = $151.74
4 weeks = x
Cross Multiply
x = 4 × $151.74
x = $606.96
3) A year
There are 52 weeks in a year
Hence,
1 week = $151.74
52 weeks = x
Cross Multiply
x = 52 × $151.74
x = $7890.48
Therefore, they made in :
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48
