Answer:
25 feet
Step-by-step explanation:
Basically that non-regulation tennis court is a rectangle. You want to know the length of the diagonal. If you draw it on paper, you'll see that this then become 2 triangles... of which you have 2 sides, and are seeking the hypotenuse. So....
H² = A² + B²
H² = 20² + 15² = 400 + 225 = 625
H = 25 feet.
Answer:
The diagonal of a non-regulation tennis court = 25 feet
Step-by-step explanation:
Pythagorean theorem
Hypotenuse² = Base² + Height²
The tennis court is like a rectangle.
We can consider the court as made of two right angled triangle
To find the length of diagonal of court
Here base = 15 feet and height = 20 feet
Diagonal or hypotenuse can be written as,
Diagonal ² = Base² + Height²
= 15² + 20²
= 225 + 400
= 625
Diagonal = √625 = 25 feet
Therefore the diagonal of a non-regulation tennis court = 25 feet

thus, 3g = 17 - 5 = 12
thus, 3g = 12
thus, g = 12/3 = 4.
Thus, g = 4.

PLEASE HELP!!!! Consider the relationship between the place values of the 4s in this number. 444.44 Choose all answers that are correct.
The 4 in the hundredths place is 10 times the value of the 4 in the tenths place.
B.
The 4 in the tens place is 10 times the value of the 4 in the ones place.
C.
The 4 in the hundredths place is times the value of the 4 in the tenths place.
D.
The 4 in the hundreds place is times the value of the 4 in the tens place.
Answers
A. The hundredths place is 10 times smaller than the tenths place, so the answer cannot be A.
B. This one makes sense, 10 is 10 times greater than 1 so the answer should be B, but let's just check the others to be sure.
C. This is the same as answer A. Hundredths is actually smaller than tenths, so the answer cannot be C.
D. This one does not give adequate information.
I believe the answer is B.The 4 in the tens place is 10 times the value of the 4 in the ones place.

5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7
Answer: (2,-7) or x=2 and y=-7
Step-by-step explanation: Took the test and can confirm this is the answer!
