Answer:
height of the tower = 2358.3 feet
Step-by-step explanation:
To solve this question, we can use the tangent relation of the angle of elevation, where the opposite side of the angle is the height of the tower minus six feet and the adjacent side of the angle is the distance from David to the tower. So, we have that:
tangent(78) = (height - 6)/500
4.7046 = (height - 6) / 500
height - 6 = 2352.3
height = 2358.3 feet
Answer:
Bus B travels faster.
Step-by-step explanation:
Bus A travels according to the equation
y = 125/2 x
This equation is in the form y = mx + b, where m = 125/2, and b = 0.
m is the slope, so the slope is 125/2 which equals 62.5
The slope is the rate of change. Since y is distance in miles, and x is time in hours, the slope is the speed in miles per hour.
The speed of Bus A is 62.5 miles per hour.
Bus B travels according to the graph. We can find the slope by using easy-to-read points on the graph. The slope is the speed in miles per hour.
Look for two points on grid line intersections since they are the easiest ones to read. Let's use point (0, 0) and point (3, 200). Now that we have 2 points, we can find the slope.
The speed of Bus 2 is 66.67 miles per hour.
Answer: Bus B travels faster.

Answer:
8 %
Step-by-step explanation:
To find the percent of trees that are over 30 ft tall, take the number of trees that are over 30 ft tall over the number of tree
Percent = trees over 30 ft tall/ total number of trees
= 6/75
=.08
Change this to a percent by multiply by 100%
.08 * 100%
8 %
Answer:
x= 2.25
Step-by-step explanation:
-3x +10= 5x -8
<em>Bring all x terms to 1 side, constants to the other:</em>
5x +3x= 10 +8
8x= 18
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>8</em><em>:</em>
x= 18 ÷8
x= 2.25
∴ The value of x is 2.25 to make the equation to be true.
