Correct question is;
Terry is filling spherical water balloons with a faucet that puts out 100 cm³ of water per second. At that rate, it takes Terry 6 seconds to fill a balloon. What is the radius of a filled balloon?
Answer:
r = 5 cm
Step-by-step explanation:
Volume of a sphere is;
V = (4/3)πr³
It takes 6 seconds to fill the balloon when a faucet that puts out 100 cm³ of water per second.
Thus,
Volume of balloon = 100 × 6 = 600 cm³
Thus;
(4/3)πr³ = 600
r³ = (600 × 3)/4π
r³ = 143.239
r = ∛143.239
r = 5.23
Approximation to the nearest whole number gives; r = 5 cm
Both have slope 4 and intercept 3 so they are coincident lines
♥ 8+7=15
♥ Therefore he started out with $15
♥ I know it's $15 because it says he paid $8 but now he has $7
♥ Therefor if we added we could check to see if its correct and it is, also if we so 15-8 we get 7.
♥ So your answer is $15<span />
The way I usually solve these problems is by using trial and error. A good way to find out about where your numbers are is by finding the square root of that number. The square root of 306 is about 17.5, so I would start with 16 and 17. 17*16=272, so I would know I had to go higher. I would then try 17*18 which equals 306. Because you need the numbers to be negative, you would make both of those numbers negative. The two integers would then be -17 and -18.
Answer:
36 miles
Step-by-step explanation:
If she can drive 12 miles only using 1/3 of a gallon of gas, that means if she uses a full gallon (3/3) she would be driving 36 miles.
12/1 x 1/3
36/1 x 3/3
Multiply the numerators by 3.
