Algebra

The  equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)

Step-by-step explanation:

Tom has read the first 40 pages of a book.

He plans to read another 12 pages each day

Since the total number of pages is p

And the Number of days required to read the book is d

if Tom read 12 pages per day, then in d days he would read 12 × d pages

h/e has already read 40 pages of the book

Then total pages of the book

p = 40 + (12 × d)

Hence, The  equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)

VARVARA [1.3K]

Answer:

mRP = 125°

mQS = 125°

mPQR = 235°

mRPQ = 305°

Step-by-step explanation:

Given that

  • mROP = 125°
  • ∠ROP is a central angle

Then:

  • measure of arc RP, mRP = mROP = 125°

Given that

  • ∠QOS and ∠ROP are vertical angles

Then:

  • mQOS = mROP = 125°
  • measure of arc QS, mQS = mROP = 125°

Given that

  • ∠QOR and ∠SOP are vertical angles

Then:

  • mQOR = mSOP

Given that

  • The addition of all central angles of a circle is 360°

Then:

mQOS + mROP + mQOR + mSOP = 360°

250° + 2mQOR = 360°

mQOR = (360°- 250°)/2

mQOR = mSOP = 55°

And (QOR and SOP are central angles):

  • measure of arc QR, mQR = mQOR = 55°
  • measure of arc SP, mSP = mSOP = 55°

Finally:

measure of arc PQR, mPQR = mQOR + mSOP + mQOS = 55° + 55° + 125° = 235°

measure of arc RPQ, mRPQ = mROP + mSOP + mQOS = 125° + 55° + 125° = 305°
