Students in the science lab are measuring the mass of an object on a triple beam balance. The object has a mass of 38 grams. Complete the table below with the absolute and percent error for each students’ measurement. Round your answer to the nearest tenths place.
Answer:
The answer is 40
Step-by-step explanation:
have a nice day!
The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB are 5%,15%, and 2.5% respectively.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Actual mass = 38
Danielle error = 40 - 38 = 2 grams
% error = 2/40 x 100 = 5%
Iris error = 4 - 34 = 6 grams
% error = 6/40 x 100 = 15%
HB error = 41 - 40 = 1 grams
% error = 1/40 x 100 = 2.5%
Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB are 5%,15%, and 2.5% respectively".

After 10 weeks, how much money would William have in his bank account?
A.$165
B.$170
C.$200
D.$314
Answer:
if he earned $20 a weak after ten weeks it would be $200
Option A is correct, $165 is the account balance of Willian after 10 weeks.
What is a function?A relation is a function if it has only One y-value for each x-value.
Given that William bank account is modeled by the function f(x)=12x+45
f(x) equal to twelve times of x plus forty five.
Where x represents the number of weeks and f(x) represents the total balance.
45 represents the initial amount.
x represents the number of weeks.
We have to find the account balance after 10 weeks.
Plug in x as 10 to find the amount after 10 weeks.
f(x)=12(10)+45
When twelve is multiplied with ten we get 120,
=120+45
Add 120 and 45 we get
=165
Hence, $165 is the account balance of Willian after 10 weeks.

A Rube Goldberg machine consists of a series of devices that perform a simple task. Kate is drawing a scale model of her Rube Goldberg machine, which she plans to build and enter into a contest. A bicycle wheel on the scale model is 2 inches in diameter, while in the actual machine, it will be 28 inches in diameter.
Question 1
Part A
Based on the measures of the wheel diameter, what is the unit rate of inches of machine per inch of the model?
Answer:
The unit rate is 16
Step-by-step explanation:
The unit rate of the machine is given as 14 inches per model.
What is Unitary method?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The diameter of bicycle wheel on the scale model is 2 inch.
And, the diameter in actual machine is 28 inch.
The unit rate of the machine can be found by using unitary method as follows,
For 2 inch diameter on scale model, diameter in machine = 28 inch
For 1 inch diameter on scale model, diameter in machine = 28/2 inch
= 14 inch.
Hence, the unit rate of inches of machine per inch of the model is 14 inches per model.
