Answer/Step-by-step explanation:
Let x hours be the number of hours Issac worked
x+6 hours be the number of hours Ruby worked
4(x+6) hours be the number of hours Svetlana worked.
x + x + 6 + 4(x+6) = 126
x + x + 6 + 4x +24 = 126
6x +30 = 126
6x = 96
x = 16
Therefore, Issac worked 16 hours.
Ruby worked 16+6 = 22 hours
Svetlana worked 22 × 4 = 88 hours.

Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3
Answer:
Undefined
Step-by-step explanation:
Given that the equation 
is a vertical line that intersects the x-axis at , there is only a change in 
, but no change in 
. Thus, the rate of change is undefined since you cannot divide by 0.
You would add up the numbers less than 5 in the die which would be 4 and divide 4 by 6 because you would divide the amount of good finishes by the possible and get 2/3 or B.
