Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%
Answer:
400 %
Step-by-step explanation:
<span>In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3</span>
To be able to give the answer to this item, we are to represent first with any variables the amount he earns each weekend for mowing the same field. Also, we represent the number of weeks he had worked by the variable y. The total amount of money he will have after working for y weeks is,
T = xy
Since, we are not given with any other information of the other expenses that have to be paid then we can say that if T is already equal to the price of the new lawnmower then, Tom will be able to purchase it and begin his lawn mowing business in due time.
The Pythagorean Theorem is a^2 +b^2 = c^2, where a and b are the sides and c is the hypotenuse ( angled line).
3.
a^2 + 6^2 = 18^2
a^2 + 36 = 324
a^2 = 324 - 36
a^2 = 288
a =√288
a = 12√2
4.
a^2 + 3^2 = 9^2
a^2 + 9 = 81
a^2 = 81-9
a^2 = 72
a = √72
a = 6√2
