Answer:
12 days
Step-by-step explanation:
Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults
3
+ 1
=
Converting to decimals
3.5 + 1.75 = 5.25 = 5
If there are 63 gallons, the water supply would last for :
63 / 5.25 =12 days
Answer:x=27
Step-by-step explanation:
Well, 225 + 75 = 300. So, that means 300 dollars per night. 1,200 ÷ 300 =400
400 Is the answer.
Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer
Answer:
7 seconds
Step-by-step explanation:
The radius of a sphere-shaped balloon increases at a rate of 2 centimeters (cm) per second.
surface area of the completely inflated balloon is 784 cm²
SA=4r²
784= 4r²
784/4= r²
196 = r²
14cm = r
Yhe radius of the complete inflated balloon is 14cm
If the ball inflate at the rate of 2 cm per seconds
Then it took 14/2 = 7 seconds to inflate fully
