A because the difference between them is 1 but started at 2 and every time u add an extra 1
9 students
30% ends up being .3%, multiply .3% by 30 students which equals 9.
We first find value of tax in dollars.
The difference between the two prices is: 23. 54 - 22 = 1.54
Therefore the sales tax in dollars is 1.54
The tax % will be (amount of tax / original cost price ) × 100
(1.54 / 22) × 100 → (0.07) × 100 = 7
So the tax rate is 7%
We can double check the answer.
7 % of 22 → (7/100) × 22 → 0.07 × 22 = 1.54
22 + 1.54 = 23.54
Answer:
1.5 miles or kilograms
Step-by-step explanation:
consider marking me brainlist
Let's analyse the function
The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have
so, the function is
