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?
Answers
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.

Gloria wants to make beef stroganoff for 12 people. Her recipe serves 8 people and calls for 4.5 pounds of ground beef. How much ground beef should Gloria purchase?
Answers
Answer:
6.75 pounds
Step-by-step explanation:
This question is of direct variation. We will use x as our answer. 8 is 2/3 of 12, so 4.5 should be 2/3 of x. We can now make an equation.
In order to solve the equation, we multiply both sides by the reciprocal of 2/3, which is 3/2.
* stands for multiplication
From solving our equation, we get 6.75. We can't forget the units, so the answer is 6.75 pounds.

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.
Answers
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".
