Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi and 1 hr/60 min. What could be the units of the initial rate of speed and the final rate of speed? Justify your answer.

Answers

The units of the initial and final rates of speed are;

Initial rate of Speed = ft/hr

Final rate of speed = mi/min

We are told that the conversion factors he used are;

5280 ft/1 mi and 1 hr/60 min

Now, the meaning of 5280 ft/1 mi denotes that;

5280 ft mile is equivalent to 1 mile

This means that the initial distance unit used was ft while the final one was mile

Also, 1 hr/60 min denotes that;

1 hour is equivalent to 60 minutes.

This means that the initial time units used was hour while the final one was minute.

In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.

Step-by-step explanation:

You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.

in this case:

45.79x0.07 = 3.205 (rounded 3.21)

Penny reads 11 pages in 1/3 hour. What is the unit rate for pages per hour? For hours per page?

Answers

Answer: 33

Step-by-step explanation:

Answer:

33 pages per hour

Step-by-step explanation:

1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.

[tex]11: 1/3 = x : 1[/tex]

2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: [tex]\frac{x}{11} =3[/tex].

3. (Solving x/11 = 3)

Step 1: Multiply both sides by 11

[tex]\frac{x}{11}*11=3*11[/tex] [tex]x = 33[/tex]

Therefore, Penny read 33 pages per hour.

If 15% of 4x is 20 less than x, what is the value of x?

Answers

The sentence "15% of 4x is 20 less than x"

translates to    0.15 • (4x)  = x – 20

Solving that…

    0.15(4x) = x - 20           multiplipy 0.15•4

          0.6x = x - 20           subtract x from both sides

         -0.4x = - 20              divide both sides by -0.4

                x = 50

We need to find the rate of how much the taxi driver charges per minute.

Therefore:

We need to pick a precise point on the line ( a precise point is a point with whole number x and y coordinates; no decimals or fractions).

We see that the point (6, 9) is precise.

A rate is a ratio in the form of a fraction that shows the relationship of change between two quantities: a/b.

So, the taxi costs 9 dollars / 6 minutes.

9/6 simplifies 2/3.

And thus, the taxi charges 2 dollars per 3 minutes

So, the answer is 9/6, which can be simplified to the furthest possibility, making it a unit rate.

Answer: 9/6



9e - 7 = 7e - 11
solve for e

Answers

Answer:

e = -2

Step-by-step explanation:

9e - 7 = 7e - 11

Subtract 7e from both side

2e - 7 = -11

Add 7 to both sides

2e = -4

Divide by 2 to isolate e

e = - 2

Answer:

e = -2

Step-by-step explanation:

9e - 7 = 7e -11

9e - 7e - 7 = -11

9e - 7e = -11 + 7

2e = -4

e = -2

a carpenter is fitting some bookcases to an alcove, using as much of the space as possible from floor to ceiling, a height of 2.5 m. The books to be fitted into the shelves are 210 mm high and a gap of at least 30 mm is necessary above each book so that they can be removed. The shelves are 20 mm thick. The alcove is 1.2 m wide. The bottom shelf should not be less than 300 mm from the ground, as the house-owner cannot bend down easily. How many shelves can be fitted into the alcove?

Answers

The number of shelves that fit in the alcove is given by the height of each shelve and the height of the bookshelf above the ground

The number of bookshelves that fit into alcove, is 8 bookshelves

Reason:

Height of the alcove = 2.5 m

Height of the books = 210 mm = 0.21 m

The gap above each book = 30 mm = 0.03 m

The thickness of the shelves = 20 mm = 0.02 m

Width of the alcove = 1.2 m

Height of the bottom shelf above the ground = 300 mm = 0.3 m

Required:

The number of shelves that can be fitted into the alcove

Solution;

Let x, represent the number of shelves that can be fitted into the alcove

We have;

An initial height of the bookshelves above the ground = 0.3 m

Height of a shelve, H = Height of books + Gap above books + Thickness of shelves

Height above ground, including the bottom shelve = 0.3 m

[tex]x = \dfrac{2.5 - (0.3)}{0.02 + 0.03 } = 8\frac{6}{13}\approx 8.46[/tex]

Therefore, the maximum number of whole bookshelves that can be fitted into alcove, x ≈ 8 bookshelves
