So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
A1 is the first term, in this case, A1 is 1
R is the ratio between adjacent numbers, in this case, R=3 because 3/1=3, 9/3=3, 27/9=3, 81/27=3
$4.20+$4.20+$4.20+$4.20+$4.20=$21.00
$7.50+$7.50+$7.50=$22.50
5 books at $4.20 costs cheaper that 3 books at $7.50. 5 books will be $1.50 cheaper
Explanation:
The purpose of trigonometry and the trigonometric ratios sine, cosine, and tangent is to help you <em>calculate</em> angles based on the ratios of side lengths of triangles they are found in.
Answer:
The coefficient is 3.
Step-by-step explanation:
Perimeter of a triangle= a+b+c
x + 10 + x + 15 + x + 12
<u>3</u>x + 37
