The 7 after the decimal is in the tenths place, so look at the one in the hundredths place. It is less than 5, so the 7 is not rounded up and stays 7. 877.7 is 877.71 rounded to the nearest tenth.
I need help with this question too but less hope we get a answer
Answer:
(D)9.5 Units
Step-by-step explanation:
We have two chords CD and AB intersecting at E.
Using the theorem of intersecting chords
AE X EB =CE X ED
AB=AE+EB
16=10+EB
EB=16-10=6
Therefore:
AE X EB =CE X ED
10 X 6 = 4 X ED
ED =60/4 =15
Therefore:
CD=CE+ED
=4+15
CD=19
Recall that CD is a diameter of the circle and;
Radius =Diameter/2
Therefore, radius of the circle =19/2 =9.5 Units
Area = perimeter + 132.
Let each side of the city be x miles long, then:-
x^2 = 4x + 132
x^2 - 4x - 132 = 0
x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2
x = 13.66, -9.66 We ignore the negative
So the city has dimension of 13.66 * 13.66
13.7 * 13.7 to nearest 10th
<span>ًWe should use the compass at one endpoint of line segment.
</span><span>Adjusting the compass to slightly longer than half the line length
</span><span>Drawing arcs above and below the segment line.
</span>Keeping the same compass width, draw arcs from other endpoint connecting the arcs cross, and draw the line segment.The inter section between the two lines represents the mid point of the line segment.
Therefore the correct answer is option C
<span>C Use the compass to copy the line segment on two arcs at equal distance from the endpoints if the segment</span>
