X = sqrt( 4 *(8+4))
x= sqrt(4*12)
x = sqrt(48)
x = 6.928 ( Round the answer as needed)
Answer:
n = 98
Step-by-step explanation:
8/11 x (n - 10) = 64
multiply both sides of the equation by 11/8
11/8 x 8/11 x (n-10) = 11/8 x 64
reduce the numbers with greatest common divisor 11
1/8 x 8 (n-10) = 11/8 x 64
n - 10 = 11 x 8
multiply the numbers
n - 10 = 88
so then you add the numbers
n = 88 + 10
n= 98
Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle = 
⇒ area = 
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²
Answer:
the probability is 0.6
Step-by-step explanation:
The computation is shown below:
Let us assume the X would be the number appear on the top face
Now
= P(X = 1) ÷ P(X = 0)
= 0.3 ÷ 0.3 + 0.1 + 0.1
= 0.3 ÷ 0.5
= 0.6
hence, the probability is 0.6
