Width of the rectangle is 12m
<u>Explanation:</u>
<u></u>
Area of rectangle = 44m
height = 
area of rectangle = length X breadth
Therefore, width of the rectangle is 12m
Answer:
D) 50/3
Step-by-step explanation:
6/10 = 10/(6+x-6)
6/10 = 10/x
6x = 100
x = 100/6
x = 50/3
Answer:
The degree of fastness by which the water is rising is 210 seconds
Step-by-step explanation:
The volume of the trough when the water depth is 20 cm is first calculated
Volume of the trough (Trapezoidal Prism) = LH (A + B) × 0.5
Where L is the length of the trough, H is the height of the trough and A and B are parallel width of the top and bottom of the trough
Volume of the trough = 7 × 0.2 (0.3 + 0.7) × 0.5 = 0.7m³
The fastness at which the water is rising is = Volume ÷ water flow rate = 0.7 ÷ 0.2 = 3.5 min = 210 seconds
Answer:
X=5
Step-by-step explanation:
3x-8=7
3x=15 (add 8 to both sides)
X=5 (divide by 3)
