Answer:
a= sqrt. 495
or
a= 22.2485954613
Step-by-step explanation:
a^2+b^2=c^2
a^2+9^2=24^2
a^2+81=576
576-81=a^2
a^2=495
Answer:
A
Step-by-step explanation:
A is the answer because its rate of change is 3 while the rest are smaller than that
3885 = 18.5 * 15 * height
The water is 14cm deep in the aquarium.
<span>Perimeter = 2L + 2W = 400 = 2(L+W)
Therefore L + W = 200
Area = L * W = 9100
Where L= Length and W = Width
Find Multiples of 9,100 which can sum up to 200. The answer is 130 and 70.
Checking.
130 * 70 = 9100
2(130 + 70) = 400
The possible width of the Fountain is 70 feet if the Length is longer or 130 feet if the length is shorter.</span>
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
