Answer:
b is the answer
Step-by-step explanation:
because I'm that bit still that bit will for ever be that bit
1. In an hour, Lance can do 1/5 of the job and Kim can do 1/4 of the same job. Letting x be the number of hours it will take them to do the job together.
(1/5 + 1/4) x = 1
The value of x is 20/9 or approximately 2.22 hours.
2. Same as the concept above, the equation that would best describe the situation is,
(1/x + 1/2x)(5) = 1
The value of x is 7.5 hours. Since this value is the number of hours Dominique can do the job alone, Houston's time will be 15 hours.
Answer:
x=-10
Step-by-step explanation:
so a triangle is 180 degrees
look at this all sides are congruent so all angles are 60
60*3=180
now solve for x
x+70=60
x=-10
FORMULA:
- Volume of hemisphere = 2/3πr³
ANSWER:
We are given a hemisphere of radius 3.1inches.
So, Volume = 2/3 × 3.14 × (3.1)³
- 187.08/3
- 62.36in³ or 62.4in³ rounded.
