Isabella had a week to read a book for a school assignment. she read an average of 3636 pages per day for the first three days and an average of pages per day for the next three days. she then finished the book by reading 1010 pages on the last day. how many pages were in the book?

Ok, you multiply 3636 by 3, because you read that many pages for the first 3 days. you do the same for 4444.

3636*3=10,908
4444*3=13,332
Then you add.

10,908+13,332=24,240
Then you add 1010.

24,240+1010=25,250
There were 25,250 pages in the book. Hope it helps!

Ibelieve the total for the tip could be $21.90

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
