Answer:
x = 9.2
Step-by-step explanation:
Use Pythagorean Theroem to find the lenght of x
a^2 + b^2 = c^2
6^2 + 7^2 = x^2
36 + 49 = x^2
85 = x^2
then find the square root of 85 which is 9.2
Answer:
The coordinates of the school should be at (10.5 , 4.25)
Step-by-step explanation:
We are dealing with two points here on a plane. These are:
Town of Coyner, Point A(3,1)
town of Coyner, Point B (18, 7.5)
in coordinate geometry, to get the mid point of two points we simply use the formula:
where x and y are the first and second points respectively
applying this formula, we have that
the mid point of the two towns is
Hence the coordinates of the school should be at (10.5 , 4.25)
For u and v to be parallel, angle 17x must equal angle 18x-3.
17x = 18x - 3 becomes x = 3 (answer)
Question 1.x - 7 > - 8
Adding 7 to both sides, we get:
x - 7 + 7 > - 8 + 7
x > -1
Thus the answer to the inequality is option Fourth.Question 2.
A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:
x is greater than 66
x > 66
So, option 1st gives the correct answer.Question 3.The tiles are square shaped and area of a square can be calculated as the square of its Length.
Area of square = (Length)²
If we are given the Area, we can find the length as:
Length =
For Tile A, the length will be:
So length is a Rational number
For Tile B, the length will be:
So length is a Rational number
For Tile C, the length will be:
So, Length is not Rational.
For Tile D, the length will be:
Length is not Rational
Thus, the lengths of Tile A and Tile B are rational only.
Therefore, the correct answer is 1st option
