os the right answer
Value of x is 76°
<u> </u><u>Step-by-step explanation:</u>
Given :- ∠JIH = 107°
and, JDI = 31°
To find :- value of x
solution:- ∠JIH + ∠JID =180° (the sum of angles on a line are supplementary)
∠JID = 180° - 107°
∠JID = 73°
Now in ΔJID
∠JID = 73° and ∠JDI = 31°
by angle some property of Δ
so, ∠JDI + ∠JID + ∠DJI = 180°
= 31° + 73° + ∠DJI = 180°
= 104° + ∠DJI = 180°
∠DJI = 180° - 104°
∠DJI = 76°
now, ∠DJI = ∠AJF = ∠X
so, x = 76°
hence value of x is 76°
Given that the 35% of area has been developed, the percentage of land that has not been developed is:
100-35
=65%
hence the acres of land that are to be developed will be:
35/65*500
=269.23 acres
the answer is 269.23
Part a)
The shape of the pool is rectangular prism, so the volume of the pool will be:
Volume = Length x Width x Depth
Volume = 6 x 3 x 1 = 18 cubic meters
Density of water = 1 gram per cubic centimeter
Density of water = 1,000,000 gram per cubic meter
Density of water = 1000 kilogram per cubic meter
Mass, volume and density are related by the following equation:
Mass = Density x Volume
Using the values, we can write:
Mass of water in pool = 1000 x 18 =18,000 kilogram
Part b)
Mass of water added to pool = 6000 kilograms
Density of water = 1000 kilogram per cubic meter
Volume = Mass/Density
Volume of water in the pool = 6 cubic meter
Since Volume = Length x Width x Depth
6 = 6 x 3 x Depth
⇒ Depth = 1/3 meters
