Explanation:
- The fence means perimeter around the court. So a tennis court's perimeter is 600 feet fence. The perimeter of a rectangle is 2 times the sum of the rectangle's length and the rectangle's width.
- It is given that length equals 60 more than width i.e. l = w + 60, where l is the length of the court and w is the width of the court.
- The perimeter of a court = 600 = 2 (l + w) = 2l + 2w = 2 (w +60) + 2w, this becomes, 2w + 120 + 2w = 600; 4w = 480, w = 120.
- Since l = w + 60, l = 120 + 60 = 180. So length of a court is 180 feet and the width of a court is 120 feet.
The answer is 7 and 4/ 7+4+11 and 7-4=3!
Answer:
Step-by-step explanation:
The formula of a volume of a cone:
r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:
La medida aproximada del lado faltante según el teorema de desigualdad de triángulos es:
- más de 12 cm y menos de 48 cm
De acuerdo con el teorema de la desigualdad del triángulo que establece que;
La suma de la longitud de 2 lados cualesquiera de un triángulo debe ser mayor que el tercer lado.
Dado que :
a = 30 cm; b = 18 cm; c =?
Basado en el teorema de la desigualdad del triángulo;
- c debe ser <(a + b)
- c <(30 + 18); c <48 cm
- También c> (a - b)
- c> (30 - 18); c> 12 cm
Por lo tanto, el lado faltante debe ser menor que 48 y mayor que 12.

Given
-- degree of freedom
Required
Determine the t-value
The given parameters can be illustrated as follows:
Where
So, we have:
To solve further, we make use of the attached the student's t distribution table.
From the attached table,
The t-value is given at the row with df = 28 and is 3.673900
Hence,
