You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?
Answers
Answer:
Hello there! :) The tip they would leave you would be of $23.23
Step-by-step explanation:
The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.
To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.
To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.

We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.
Answer:
x=29 degrees
Step-by-step explanation:
Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.
Since the angles on the right must add up to 90, we set an equation to solve for x:
61+x=90(subtract 61)
x=29 degrees

A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2
Answers
Answer:
C) 40 cm²
Step-by-step explanation:
area of top triangle = 1/2 x 8 x 6 = 24 cm²
area of bottom triangle = 1/2 x 8 x 4 = 16 cm²
24 cm² + 16 cm² = 40 cm²
The area of the top is :1/2x8x6=24 cm
Next!!
The area of the bottom is:1/2x8x4=16cm
Next!!
24 cm +16 cm = 40cm

A) 2% B)11% C)13% D) 20%
Answers
Answer:
B 11%
Step-by-step explanation:
The total number of marbles is
12+4+2 = 18
P( blue) = number of blue marbles / total marbles
= 2 blue/ 18 total
= 1/9
=.11111
= 11.11%
Please answer this correct
Answers
Answer:
C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.

Write an explicit formula for a , the nth term of the sequence 7, 14, 28, ...
Answers
Answer:
The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).
Here are the first few terms of the sequence:
n = 1: a_1 = 7
n = 2: a_2 = 14
n = 3: a_3 = 28
n = 4: a_4 = 56
n = 5: a_5 = 112
As you can see, the formula works for all values of n.
