Find the lengths of nails with the following penny sizes: 3, 6, and 10. The 3-penny nail is inches. the 6 penny is__ the 3 penny
stealth61 [152]

the lengths of nails with the following penny sizes: 3, 6, and 10

  • A 3-penny nail is_5/4_inches.
  • A 6-penny nail is_2_inches.
  • A 10-penny nail is_3_inches.

This is further explained below.

<h3>What is the lengths of nails with the following penny sizes: 3, 6, and 10?</h3>

That is the equation solved for n.

The penny size is d, and n is the length of the nail, then:

if d = 3, we have:

n = (3 + 2)/4 = 5/4

if d = 6, then

n = (6 + 2)/4 = 2

if d = 10, then:

n = (10 + 2)/4 = 3

Thus:

A 3-penny nail is_5/4_inches.

A 6-penny nail is_2_inches.

A 10-penny nail is_3_inches.

Please help with answer and number line​
goblinko [34]

Answer:

Graph uploaded!

Step-by-step explanation:

<u>First, let's solve the distributive property.</u>

  • 4/5(x - 2) ≤ 6
  • => 4x/5 - 8/5 ≤ 6
  • => 4x/5 ≤ 6 + 8/5
  • => 4x/5 ≤ 38/5
  • => x ≤ 19/2

Now, let's plot this inequality on the line. Please check my graph.

Hoped this helped!

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructo
Reika [66]

Answer:

19/37

Step-by-step explanation:

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor

Total number of people in the faculty =

9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors

= 37 people

Hence,

The probability of choosing a professor or an instructor

= P( Professor) + P( Instructor)

= 9/37 + 10/37

= 19/37
