Answer:
5.45 hours or 5 hours 27 minutes to nearest minute.
Step-by-step explanation:
We work in rates per hour.
Kevin does 1/10 of the roof in an hour and Sam does 1/12 of the roof/hour.
Now we add to get the equation:
1/10 + 1/12 = 1 / x where x is the time they take to repair the roof working together.
Multiplying through by the LCM 60x:
6x + 5x = 60
11x = 60
x =60/11
x = 5.45 hours.
We have to find the volume of the cylinder, where: r = 5 m and h = 147 m.
V = r² h π
V = 5² · 147 · 3.14 = 25 · 147 · 3.14 = 11,539.5 m³
Answer:
11,539.5 m³ of soil has to be excavated.
Answer:
English: the diagonal length and probably be 22.2
Spanish: la longitud diagonal y probablemente sea 22,2

Answer:</h2>
To figure this out you need this formula: y = mx + b.
- m (or slope) = -5
- b (or the y-intercept) = 10
Well these are corresponding angles and equal
so, 5x + 15 = 115
x = 100/ 5
= 20
