Answer:
20%
Step-by-step explanation:
To change a fraction to a percentage , multiply by 100%
× 100%
= 0.2 × 100%
= 20%
75%
30/40 means its 75% out of 100%
75$ representing the 30 and the 100$ representing the 40
Step-by-step explanation:
Tax charge
80 × 6.75/100 = 5.4
Cost + tax charge
80 + 5.4 = 85.4
Tip (15% of cost and tax)
85.4 × 15/100 = 12.81
(Cost + tax charge + tip)
85.40 + 12.81 = 98.21
therefore, $95 is not enough.
Sin (a+b) = sin a. cos b + cos a. sin b
a= 50° and b=40°, then
sin(50+40) = sin 50° . cos 40° + cos 50° . sin 40°
sin(50+40) = sin 90° = 1 and
sin 50° . cos 40° + cos 50° . sin 40° = 1
Answer:
5a+5b
Step-by-step explanation:
Multiply each variable in the parenthesis by the number outside.
Hope this helps.
