Answer:
153.2 gallons per day
Step-by-step explanation:
To find out how much water he used each day, take the amount of water he used and divide by the number of days
1072.4 gallons / 7 days
153.2 gallons per day
Area (square mirror)=side²
Therefore:
side²=256 in²
side=√(256 in²)=16 in
Rectangular mirror:
width= square mirror width=side=16 in
length=(width + 2 in)=16 in + 2 in=18 in.
Area(rectangular mirror)=length x width.
Area (rectangular mirror)=(18 in)(16 in)=288 in².
Answer: the area of a rectangular mirror is 288 in².
Answer:
729 is a perfect square
Step-by-step explanation:
because 27 * 27 = 729
Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
Answer:
Mechanical advantage = Effort distance/Resistance distance
Effort distance = D - Fulcrum = 0.5 m
Resistance distance = A - Fulcrum = 2.0 m
Then,
Mechanical advantage = 0.5/2 = 0.25
Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.
