Step-by-step explanation:
Answer:659.64 feet
Step-by-step explanation:
We are given that a cell phone tower is anchored by two cables on each side for support. The cables stretch from the top of the tower to the ground, with each being equidistant from the base of the tower so first of all we have to draw a diagram for this scenario as shown below figure 1
Next we are given that angle of depression from the top of the tower to the point in which the cable reaches the ground is 23 degrees as shown in figure 2
So from here we can conclude that as tower is 140 feet tall and the base angle between cable and ground would be also 23 degrees
so we just the trigonometric identity to find x
tan(theta) = opposite over hypotenuse
we know the angle theta = 23
opposite = 140 ( height of tower)
and base is the distance on one side of tower
so finally tan 23 = 140/x (tan = opposite over adjacent)
doing cross multiplication we get
x = 140 / tan 23
x = 329.82(rounded to hundredth)
so total ground distance between the cables = 2x = 2(329.82) = 659.64 feet
Answer:
Company X - 190 students
Company Y - 114 students
No phones - 76 students
Step-by-step explanation:
1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population
380/120 = 3.16666667 or 3 & 1/6
380 comes from the total population of students and 120 comes from the randomly selected.
2) Use our multiplier to compare the results to the population
<u>People with Company X</u>
<u>People with Company Y </u>
<u>People with no cell phone</u>
- 24 * 3.166667 = 76.0000000001 = 76 (rounded)
<u>Double check</u>
190 + 114 + 76 = 380
The answer to the nearest square centimeters is 1,652 cm2.
The calculation can be calculated as follows :
The first step is to convert the tile measures in inches to centimeters.
1 inch = 2.54 centimeters
16 inches = 16 x 2.54 centimeters
16 inches = 40.64 centimeters
The second step is to calculate the area of the tile in square centimeters.
Tile's area in square centimeters
= 40.64 x 40.64
= 1,651.6096 cm2
The last step is to round the answer to the nearest square centimeters.
= 1,651.6096 cm2
= 1,652 cm2
Hence, the area of the tile in square centimeters is 1,652 cm2.

30% = 30/100
= 0.3
Now if we say that x% of a number is y then it actually means that x% multiplied by that number would be equal to y, thus:
30%*56 = 0.3*56
= 16.8
