Answer:
Step-by-step explanation:
Let the number of floors = x
Number of apartments per floor = 4x
4x *x = 100
4x² = 100
x² = 100/4
x² = 25
x =√25
x = 5
Number of apartments on each floor = 4*5 = 20
You do 822.6 divided by 18
It is equal to 45.7
45.7 km per hour
Solve the system of equations:
y=2x+2 ................(1)
y=-2x+a+1............(2)
for x and y
(1)-(2)
4x-a+1=0 => x=(a-1)/4
(1)+(2)
2y=a+3 => y=(a+3)/2
x>0 if (a-1)/4>0 => a>1
y>0 if (a+3)/2>0 => a>-3
For both x & y >0, we have the condition a>1.
Note that if a=1, then the intersection poin lies ON the x-axis, and therefore NOT in quadrant 1.
The total capacity will be 8 2/5 liters.
<h3>How to calculate the fraction?</h3>
From the information, the bottles wee filled with 6/5 liters each.
Therefore, the capacity will be:
= Number of drums × Quantity
= 7 × 6/5
= 42/5..
= 8 2/5 liters.
Therefore, the total capacity will be 8 2/5 liters.
