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 1

Answer:

The unit rate is 16

Step-by-step explanation:

Answer 2

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.

Today, everything at a store is on sale. The store offers a 20% discount.

a) The regular price of a T-shirt is $18. What is the discount price?

b) If the regular price of an item is dollars, what is the discount price in dollars? Write an expression.

c) The discount price of a hat is $18. What is the regular price?

Answers

Answer:

a. $14.4

b. $18 • .2 = $3.6

c. $21.6

Step-by-step explanation:

a. Make the 20% a decimal, and multiply by the regular price. Then, subtract that and you'll get the discounted price.

18 • .2 = 3.6

18-3.6 = $14.4

b. Use the equation multiplying the 20% as a fraction here.

c. Multiply $18 by .2 (the discount). Then, add that to the discount price ($18).

18 • .2 = 3.6

3.6 + 18 = $21.6

Lucy is shopping for her younger brother's birthday party. All ten of their family members will be at the party.

She finds a package of five noise-makers for $1.50. At this rate, how many packages will she need to buy so that each person has one noise maker?

A.4 packages
B.12 packages
C.6 packages
D.3 packages
E.2 packages

Answers

Answer:

2

Step-by-step explanation:

one package has 5 and 5+5 =10 the amount of people at her brothers party so if one package has 5 and it takes two 5s to get to 10 then it is two

hopefully this helps :)

2 packages because there is 10 family members and each package brings 5 so if it brings 5 then 2 packages would be 10. there are 10 family members so each family member will have a noise maker

Ross has a model truck. It has a scale of 1 inch for every 32 inches on a real-sized truck. He wants to build a garage for the model at the same scale.

Given that the garage for a real-sized truck is 12 feet wide, how wide should his model garage be?

Answers

Answer in decimal form:  4.5 inches

Answer as a mixed number = 4 & 1/2 inches

========================================================

Explanation:

" It has a scale of 1 inch for every 32 inches on a real-sized truck" means the the scale is 1:32

Put another way, the real life width is 32 times greater than the scale model.

So we can form the equation

y = 32x

where x is the scale model width and y is the actual real life width.

---------

The garage in the real world is 12 feet wide, or 12*12 = 144 inches wide.

Plug y = 144 into the equation and solve for x

y = 32x

32x = y

32x = 144

x = 144/32

x = 4.5

His scale model garage must be 4.5 inches wide

4.5 inches = 4 & 1/2 inches = 4 and a half inches

Answer:

4.5 inches

Step-by-step explanation:

First, convert all measurements to the mase units

12 feet  ->  144 in

Now, we will identify what 144 inches would be as a model scale. We will do so by dividing 144/32 since 32inches equals 1 model scale inch.

144/32= 4.5

therefore, the garage will be 4.5 inches as a model scale.
