Answer:

We can conclude that the chapter 7 test will also have 20-30 questions on it.

Step-by-step explanation:

All tests for the first six chapters of a textbook had 20–30 questions.

The chapter 7 test will be given tomorrow.

Hence, based on reasoning, we can say that the chapter 7 test can also have 20-30 questions in it.

The probability is also high as all the 6 previous tests had 20 to 30 questions. Hence, it is very likely that the 7th test will also have same number of questions.

A student charges twenty dollars per hour to type college papers. The student's average typing speed is fifty words per minute.
coldgirl [10]

Answer:

The student should charge $210 for typing the paper ⇒ answer C

Step-by-step explanation:

* Lets explain how to solve the problem

- The rate of the student's typing is 50 words per minute

- The students charges twenty dollars per hour to type the college

 papers

- There is a paper contains 31,500 words

- We want to now how much the student should charge for it

* At first lets find his rate per hour

∵ 1 hour = 60 minutes

∴ 1 minute = 1/60 hours

∵ His rate = 50 words / 1 minute

- Lets change the minute to hour

∴ His rate = 50/(1 × 1/60) = 3000 words per hour

* Lets find the time he needs to finish the paper

∵ The paper contains 31,500 words

∵ Time = The number of words ÷ his rate of typing

∵ his rate is 3000 words per hour

∴ Time = 31,500 ÷ 3000 = 10.5 hours

∴ He needs 10.5 hours to finish the paper

∵ He charges $20 per hour

∵ The time to finish the paper is 10.5 hours

∵ The price of typing the paper = the charge per hour × number

   of hours

∴ The price of typing the paper = 20 × 10.5 = 210

∴ The student should charge $210 for typing the paper

The points (10,8) and (4,5) fall on a particular line. What is its equation in point-slope form?
FinnZ [79.3K]

Answer:

y-8=1/2(x-10)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(5-8)/(4-10)

m=-3/-6

simplify

m=1/2

y-y1=m(x-x1)

y-8=1/2(x-10)
