Answer:
The focii are 8 feet apart
Step-by-step explanation:
You can use the formula
F = √(a^2 - b^2) where F is the distance of the focii from the center , a = length of the semi major axis and b = length of the semi minor axis)
So here it is √(5^2 - 3^2)
= √16 = 4
So the distance is 2*4 = 8
Step-by-step explanation:
When adding fractions of different denominators, first find the LCM of the denominators, but she ignored that.
11/4+2/3
LCM=12
(33+8)/12
41/12
Answer:
1 / 5
Step-by-step explanation:
n ( S ) = 5 + 12 + 8 + 10 + 15
n ( S ) = 50
Let R be the event of getting red jellybean.
n ( R ) = 10
P ( R ) = n ( R ) / n ( S )
= 10 / 50
P ( R ) = 1 / 5
