Answer:
-7/ 48
Step-by-step explanation:
Given that:
Average change in water level per 3 years = - 7/16
This means the water level decreases by - 7/16 on average every 3 years
The change in water level after a year will be ;
-7/16 = 3
x = 1
Cross multiply ;
3x = - 7/16
Divide both sides by 3
x = -7/16 ÷ 3
x = - 7/16 * 1/3
x = - 7 / 48
Hence, water level will change by - 7/48 after a year.
3 meters would be your answer
Answer:
16-2n=-8+4n-12
16+8+12=4n
36/4=n
9=n

Answer:
Correct answer is option <em>D)</em> Construct the bisector of an angle.
Step-by-step explanation:
Angle bisector of an angle is a line that divides the angle in two equal parts.
A Line <em>BD</em> is called the angle bisector of
if

Please refer to image attached.
As per the question image, if the line PW is joined it will be the angle bisector of
.
Steps of construction of angle bisector:
1. Draw the angle QPR.
2. Open compass and make an arc that will cut the two lines on points Q and R respectively as shown in question figure.
3. With the same compass opening, put the compass on Q and make an arc in the area between
.
4. Draw an arc keeping the compass on R to cut the previous arc on point W.
Line joining the points P and W is the angle bisector of
.
So, Correct answer is option <em>D)</em> Construct the bisector of an angle.
