Answer:
1. $67.72
2. It's correct.
Step-by-step explanation:
1.
bill: $68.89
discount: $10
tip: 15%
Calculate the total with the discount.
68.89-10=58.89
Now calculate 15% of that.
Convert 15% to decimal by dividing by 100
Multiply
Add this to the original amount.
----------------------------------------------------------------------------
Calculate 20% of 148.25
Convert 20% to decimals by dividing by 100
Multiply
This is how much they will tip.
Add this to the original bill;
Answer: the answer is 150 :)
Step-by-step explanation: Volume of a cone is
V = 1/3 pi * r^2 *h
The volume of one cone is
pi = 3.14
r = d/2 = 6/2 =3
h=9
Substitute what we know
V = 1/3 * (3.14) * (3^2) * (9)
= 27* 3.14
= 84.78 cm^3
The water cooler has 12717 cm^3 water
Divide the water by the volume of the paper cup cone and we will know how many paper cup cones we can fill, assuming we fill them completely.
12717/ 84.78 = 150
We can fill 150 paper cup cones. have a great day!
It would be: - 2 - (-10) = 5x - 12
= -2 + 10 = 5x - 12
= 8 + 12 = 5x
= x = 20 / 5
= x = 4
Answer:
Terms (Variables) = x , d . Their corresponding coefficients = n^2 , 1/2 . Constant = 6
Step-by-step explanation:
6 + n x n + 1/2d
6 + n^2 x + 1/2d
Terms (Variables) = x , d . Their corresponding coefficients = n^2 , 1/2 . Constant = 6
