Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Answer:
Normal selling price is Rs 4500
Explanation:
1) Selling price = original price × (100-d) / 100
d = reduced price percentage
2) Rearrange the formula
original price = (selling price × 100) / (100 - d)
S.p = 3825
d= 15%
let original price = x
Therefore
x = (s.p×100) / (100-d)
x = (3825×100) ÷ (100-15)
x = 382500/85
x = 4500
We can tell any number is solution of any equation
by plugging that number into equation
and then we check whether it satisfies the given equation
For example:
(1)
Let's assume we have given solution x=1 of
now, we can plug x=1 to verify it
we can see that both sides are equal to 0
so, x=1 will be solution of this equation
(2)
Let's assume we are given x=2 is the solution
now, we can verify it in same way
now, we can plug x=2 to verify it
we know that -1 can not be equal to 0
so, x=2 does not satisfy this equation
so, x=2 can not be solution of this equation
Answer:
Step-by-step explanation:
Basically, you divide 3 1/4 by 1/4. To do that, you have to change the mixed number into an improper fraction. 3 1/4 as an improper fraction is 13/4. I was able to find that since you simply just multiply the denominator by the whole number, 4 x 3, which is 12, then add 12 to the numerator, 1, which is 13. Finally, the improper fraction is 13/4 (the denominator stays the same). Now, we can divide the fractions. One rule about fractions: dividing them is the same as multiplying them with the reciprocal of the other. Like say for example, the reciprocal of 1/5 is 5/1.
Let's solve:
13/4 divided by 1/4 =
13/4 x 4/1 = At this point, you just multiply them straight across.
52/4 = It's not simplified since both can still be divided. So, you simplify by finding the greatest common multiple of 52 and 4, which is 4. 52 divided by 4 = 13; 4 divided by 4 = 1.
52/4 = 13/1 = 13 (any numerator with the denominator of one is a whole number when simplified)
So if Julie needs 3 1/4 cups of oatmeal, she will use 13 of 1/4 cups of oatmeal. Answer's 13. :) I really hope I helped!
