Answer:
You can use the midpoint formula.
Method:
MAB = (Ax+Bx)/2 ; (Ay+By)/2
Substitute in what you have:
(2;4) = (Ax+3)/2 ; (Ay+7)/2
Because we know the x coordinate of the midpoint, we can assume that:
2 = (Ax+3)/2
And now solve for Ax:
4 = Ax+3
Ax = 1
Because we know the y coordinate of the midpoint, we can assume that:
4 = (Ay+7)/2
And now solve for Ay:
8 = Ay+7
Ay = 1
Therefore A(1;1)
Answer: 16875
Step-by-step explanation:
Let the price of the washing machine be x.
Since she loses 20% in the bargain, this implies that she sold it at (100% - 20%) = 80%.
Therefore, 80% of x = 13500
0.8 × x = 13500
0.8x = 13500
Divide both side by 0.8
0.8x/0.8 = 13500/0.8
x = 16875
Therefore, the price at which she bought the washing machine is 16875 rupees.
Answer:
74.15
Step-by-step explanation:
this is bc there are ten spaces between 74.1 and 74.2. halfway between that is another 00.05 points.
Since it is to the third, we move the decimal point three places over to the right:
4.16 ---> 4,160
What ever the power, move it over that amount.
If the power is negative,move it that amount to the left, making it smaller.
Hope this helps!
Answer:
Different type of real numbers include natural numbers, whole numbers, integers, irrational numbers, and rational numbers. Natural numbers are the set of numbers (1, 2, 3, 4...) also known as counting numbers. Whole numbers are natural numbers including zero (0, 1, 2, 3, 4...). Integers are the set of whole numbers and their opposites (-3, -2, -1, 0, 1, 2, 3...). Irrational numbers are numbers that cannot be expressed as a ratio of two integers. Their decimal expansions are nonending and nonrepeating. An example of an irrational number is pi (3.14). A rational number is a number that can be written as a fraction. It includes integers, terminating decimals, and repeating decimals. An example of a rational number is the number 214.
