I’m not sure but I think u can just subtract 2-1,65 and than multiply by 100
LenaWriter [7]3 years ago

Answer:

21%

Step-by-step explanation:

to find percent error you subtract the theoretical (actual) from the experimental, then divide by the theoretical; what you get is a decimal so if you multiply it by 100 you will get the percent

theoretical = 2.0 grams

experimental = 1.65 grams

(1.65 - 2.0) / 1.65 = -0.35/1.65 = -0.21

0.21 x 100 = 21 %

the scale has a 21% probability of being inaccurate

slavikrds [6]

Answer:

x = 33

Step-by-step explanation:

Given

Students = 28

Brownies = 23

Brownies = 2\ per\ student

Required

Determine the number of brownies left

If:

Brownies = 2\ per\ student

and there are 28 students

Then:

Total\ Brownies = 2 * 28

Total\ Brownies = 56

To determine the number of brownies left, we have:

Total\ Brownies = Brownies\ Made + Brownies\ Left

x + 23 = 56

Collect Like Terms

x = 56 - 23

x = 33

<em>Hence, there are 33 brownies left</em>

Sedaia [141]

Answer:

$384.75

Step-by-step explanation:

Albert's hourly pay is $8.10

When he works for more than 40 hours, his hourly pay will increase to $12.15.

Last week, Albert worked for 45 hours, his hourly pay would be:

First 40 hours = $8.10 * 40 = $324

Remaining 5 hours =

$12.15 * 5 = $60.75

Albert gross pay for this period will be calculated as:

$324 + $60.75 = $384.75

Therefore, Albert gross pay for this period = $384.75
