If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
The answer should be 112 degrees
Answer: 14
Step-by-step explanation:
Fraction that choose hip hop= 1/3
Fraction that choose rap = 1/5
Fraction that choose rock will be:
= 1 - (1/3 + 1/5)
= 1 - (5/15 + 3/15)
= 1 - 8/15
= 7/15
Number of students that choose rock will be:
= 7/15 × 30
= 7 × 2
= 14 students
We then multi
Answer:
64.
Step-by-step explanation:
Sigma notation is ∑48(1/4)^(n-1).
Upper limit = a1 / (1 - r) where a1 = initial population and r = common ratio.
So it is 48 / (1 - 1/4)
= 48 / 3/4
= 48 * 4/3
= 64.
