What do your question contain of?
Answer:
x = 2.8 units
Step-by-step explanation:
volume = width x length x height
23.52 = 1.5 x 5.6 x height
height = 23.52/(1.5 x 5.6) = 23.52/8.4 = 2.8 units
To solve this, we simply need to break down the words and turn each part into an equation.
"Three times"
This shows that we will be multiplying 3 and something.
3*
"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n
"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16
Using the logic above, we can see that the equation to represent this is 3n+16.
Answer:
60.2 m
Step-by-step explanation:
Let x represent the width of the river. The distance from the point across from the tree to the second point is 15 m. The angle from this point to the tree across the river is 76°.
This makes the side opposite the angle x, the width of the river. It also means the 15 m side is adjacent to this angle.
The ratio opposite/adjacent is the ratio for tangent; this gives us the equation
x/15 = tan(76)
Multiply both sides by 15:
15(x/15) = 15(tan(76))
x = 15(tan(76)) ≈ 60.2
The water will last for 3 days
<em><u>Solution:</u></em>
Given that, village having a population of 4000, requires 150 litres of water per head per day
<em><u>Let us first find the volume of tank</u></em>
The tank measuring 20m x 15m x 6m
Length = 20 m
Breadth = 15 m
Height = 6 m
Thus volume of tank is 1800 cubic meter
From given,
Water required per person per day = 150 liters
<em><u>Therefore, water required for 4000 people per day is:</u></em>
Convert to meters
<em><u>How many days will the water of this tank last?</u></em>
Thus the water will last for 3 days
