Answer:
12 launches
Step-by-step explanation:
Let's represent this with two equations, with C(r) representing cost of buying, x representing each day you launch, C(r) representing cost of renting.
Cost of buying = 197 + 8x
C(b) = 198 + 8x
Cost of renting = 10 + 25x
C(r) = 10 + 25x
The question asks us when it will not matter. This means that we want to find when the cost is equal for renting and buying. So set these equations equal:
198 + 8x = 10 + 25x
Subtract 10 from both sides:
188 + 8x = 25x
Subtract 8x from both sides:
188 = 17x
Divide both sides by 17:
188/17 = x
x = 11.06, round this up to 12 days. (At the 11th day, it still matters.)
<u>It will not matter after 12 launches.</u>
Answer:
π/6 ≈ 11/21 cubic units
Step-by-step explanation:
Use the given values in the formula for the volume of a sphere:
V = 4/3πr³
V = (4/3)(22/7)(1/2)³ = 4·22/(3·7·8) = 11/21 . . . . cubic units
Answer:
The answer would be z/6 + 5 - 8.
Step-by-step explanation:
Quotient means the answer to a division problem, so we know that z and 6 must be divided. Then it tells us to add 5 to the quotient and then subtract 8 from the total. Because of PEMDAS no parentheses are needed.
If TWO points lie in a plane, the LINE containing them also lies in the same plane.
