Answer:
4.5
Step-by-step explanation:
The median we know is the middle number of a set of numbers. Putting the set in least to great order, we have (1, 3, 3, 6, 8, 9). The middle number here is 3 and 6. We take the mean of 3 and 6, (3+6)/2 which gives us 4.5 and that is our answer.
Answer: $443.32
Step-by-step explanation:
Hi, to answer this question we have to calculate perimeter of a semicircle:
P = π (d/2) + d
Where d is the diameter
Replacing with the values given:
P = 3.14 (23/2) + 23 = 59.11 feet
Since each linear foot cost $7.50, we have to multiply that cost by the perimeter.
59.11 x 7.50 = $443.32

<h2>A 30-meter high building sits on top of a 151.52 meter high hill.</h2>
Explanation:
According to the given data, we can draw a figure (Please refer the attachment below)
Building's height = 30 meter
Angle of elevation from a spot to the top of the building = 55 degrees
Angle of elevation from the spot to the top of the building = 50 degrees
To find the height of the hill, we need to use the formula,

then, 

.... (1)
Similarly, 

.... (2)
(1) = (2) becomes

[tex]\Rightarrow [tex] 1.428h = (30 + h)1.192
1.428h = 35.76 + 1.192h
1.428h - 1.192h = 35.76
0.236h = 35.76
h = 151.52 meter
Therefore, the hill highs 151.52 meter.
Answer:
3x2-6x+1=0= 7/6
Step-by-step explanation:
3x2-6x+1=0
-6x=-7
than divide each term in -6x=-7 by -6 and simplify
x= 7/6
