Answer:
170 pages
Step-by-step explanation:
Roberto must read a book that contains 340 pages in 4 days for which he plans the following distribution
The number of pages he read for the first day :
The first day 1/5 of the pages of the book
This is calculated as:
1/5 × 340 pages
= 68 pages
For the second day:
The second 1/4 of what remains to be read
The number of pages remaining after the first day is calculated as:
340 - 68 = 272 pages
Hence, the number of pages read on the second day is
1/4 × 272 pages
= 68 pages
For the third day
One the third day, 1/6 of the rest was read.
The number of pages remaining after the first day is calculated as:
272 - 68 = 204 pages
Hence, the number of pages read on the third day is
1/6 × 204 pages
= 34 pages
Therefore, the number of pages Roberto has to read on the fourth day is calculated as:
340 pages - (68 + 68 + 34)pages
340 pages - 170 pages
= 170 pages
The angle of B is 
Explanation:
It is given that
and 
To determine the
, let us use the law of sine formula.
Thus, we have,

Substituting the values in the formula, we have,

Multiplying both sides by 3,we get,

Simplifying and dividing, we get,

Multiplying both sides by
, we get,

Thus, 
Hence, The angle of B is 
Answer:
P = 15.42 cm
Step-by-step explanation:
Perimeter of circle = (πD/2)+D
Where D = 6 cm
P =( (3.14)(6)/2) + 6
P = (3.14)(3)+6
P = 9.4 + 6
P = 15.4 cm
