Answer:
Best deal: 12 for $6
Worst deal: 3 for $2
29.06% difference
Step-by-step explanation:
2.00/3= 0.67
3.50/6= 0.58
6.00/12= 0.50
13.00/24= 0.54
Best deal: 12 for $6
Worst deal: 3 for $2
% difference: (0.67-0.50)/((0.67-0.50)/2) x 100= 29.06% difference
Answer:
27 pages.
Step-by-step explanation:
Let l be the number of pages in the long paper and s be the number of pages in the short paper.
We have been given that the total number of pages for both papers is 40. We can represent this information in an equation as:
We are also told that the number of pages in the long paper is one more than two times the number of pages in the short paper. We can represent this information in an equation as:
We will use substitution method to solve system of linear equations.
From equation (1) we will get,
Upon substituting this value in equation (2) we will get,
Upon adding 2l to both sides of our equation we will get,
Let us divide both sides of our equation by 3 we will get,
Therefore, there must be 27 pages in the long paper.
Answer:
<u>The original price of the laptop was US$ 875</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Sale price of the laptop = US$ 525
Discount from the original price = 40%
2. Let's find the original price of the laptop
Original price of the laptop = x
Sale price of the laptop = US$ 525
Sale price of the laptop = x - 40%x
525 = x - 0.4x
525 = x - 4x/10 (0.4 = 4/10)
5,250 = 10x -4x (Multiplying by 10 at both sides)
5,250 = 6x
5,250/6 = 6x/6 (Dividing by 6 at both sides)
875 = 6
<u>The original price of the laptop was US$ 875</u>
Answer:
200 m s^-2.
133.33 ms^-2.
100 m s^-2.
Step-by-step explanation:
Use Newton's Second Law of motion:
Force = mass * acceleration
The force is in Newtons so the mass must be in kilograms#
100 g = 0.1 kg. So:
20 = 0.1 * a
a = 20/ 0.1 = 200 m s^-2.
We calculate the acceleration for the 150g and 200g potato in the same way.
