Answer:
- x/10 = 9
multiply by 10 on both sides
-x = 90
divided by -1 on both sides
x = -90

Answer:</h3>
A. 28
<h3>
Step-by-step explanation:</h3>
We assume m is the measure of the marked unknown angles: ∠BZY ≅ ∠BZA
(5x +3)° = (2x +18)°
Divide by ° and subtract 2x+3:
... 3x = 15
... x = 5
Then ∠BZA = (2·5 +18)° = m = 28°
Answer:
64 square units
Step-by-step explanation:
if you spilt up the polygon you can find the area of the square and triangle making up the square.
length * width = Area; 6 * 8 = 48 sq units for the square part
1/2 * base * height = Area; 1/2 * 4 * 8 = 16 sq units for the triangle part
then add the two areas together for the area of the entire polygon:
48 + 16 = 64 sq units

Answer with explanation:
It is gven that, Three taps A, B and C are emptying the tank.
Time taken by Tap A to empty the tank completely =17.0 Hours
Time taken by Tap B to empty the tank completely =6.8 Hours
Time taken by Tap C to empty the tank completely =5.2 Hours
Time taken by three taps, A , B and C together to empty the tank completely
Let V be the volume of water in the tank.
→Volume of water in the tank after half an hour when the tap C has been blocked
→→% of Volume of water in the tank after half an hour, when the tap C has been blocked
=19.91%
Let Time taken by the taps to empty the tank =t hours
When volume of water out of the tank is equal to volume of water inside the tank , the tank is said to be emptied.
=2.52 hours (Approx)
