Look at the ratio (2:3). You can see that the numbers of "ratio units" add up to 5, and that the total number of books is 100 times that value. Then each "ratio unit" stands for 100 books.
3 ratio units of chapter books mean there are 300 chapter books.

Answer:
79 degrees.
Step-by-step explanation:
M < 4 = m < 1 + m <3 (External Angle of a Triangle Theorem).
m < 4 = 26 + 53
= 79 degrees.
4 = amount
<span>8 = base </span>
<span>amount / base = percent </span>
<span>4 / 8 = 0.50 </span>
<span>multiply 100 times the decimal and attact he % symbol </span>
<span>100 x 0.5 = 50 % </span>
<span>4 is 50% of 8 </span>
747 divide 2= $373.5
then 373.5 in a ratio = 3:7
Answer:
cos60° = 
Step-by-step explanation:
Using the cofunction identity
• cos(90 - x)° = sinx°, hence
sin30° = cos(90 - 30)° = cos60° =
