Answer:
Q1) Answer: After 3 minutes there will be 4.8 gallons of water in the fish tank. Q2) Answer: 40 gallons of water will be filled after 25 minutes.
Answer:
(4, - 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 
, 
]
Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then
midpoint = ( 
, 
) = 
, 
) = (4, - 0.5 )
Well, first you need to decide what place you want to round it TO.
Example: Round it to the nearest hundredth:
The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .
-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .
Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.
I'm curious . . . where did this number come from ?
It happens to be one thousandth of the speed of light, in miles per hour.
Did it come up in science class, or did a science geek use it for
one of the problems in math ?
Answer: x=−1 or x=1 or x=−2 or x=3
Step-by-step explanation: Step 1: Factor left side of equation.
(x+1)(x−1)(x+2)(x−3)=0
Step 2: Set factors equal to 0.
x+1=0 or x−1=0 or x+2=0 or x−3=0
x=−1 or x=1 or x=−2 or x=3
Answer:
1
