Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Please help!!
Answer:
63.44 feet
Step-by-step explanation:
tan(68 degrees)= 85/y
y tan (68 degrees)=85
y=85/tan(68 degrees) ( cross multiply)
y = 34.34 feet
tan (41 degrees)=85/x+y
(x+y)tan(41 degrees)=85
x+y=85/tan 41 degrees
x=85/tan(41 degrees) - y
x= 85/tan (41 degrees)-(34.34) (cross multiply)
Therefore, Travis stepped back 63.44 feet to gain a better view!
what is the correct equation
Answer: y = 0.4x
In fraction form, this is y = (2/5)x
================================================
Explanation:
For each row, divide the y over x values
Row One: y/x = 0.8/2 = 0.4Row Two: y/x = 4/10 = 0.4Row Three: y/x = 6/15 = 0.4Row Four: y/x = 10/25 = 0.4We end up with the same thing each time.
Since y/x = 0.4, this rearranges to y = 0.4x
Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

What is the area of this polygon?
Enter your answer in the box.
=========================================================
Explanation:
Draw a vertical line through the middle to split the figure into two rectangles.
The rectangle on the left is 21 ft by 7 ft. Its area is 21*7 = 147 sq ft.
The rectangle on the right is 24-7 = 17 ft by 21-10 = 11 ft. The area is 17*11 = 187 sq ft.
The combined area is therefore: 147+187 = 334 square feet
-------------
A different approach:
Draw a horizontal line through the middle to form two rectangles.
The rectangle on top is 10 ft by 7 ft with area of 10*7 = 70 sq ft.
The rectangle on the bottom is 24 ft by 12-10 = 11 ft, so its area is 24*11 = 264 sq ft.
Total area = 70+264 = 334 square feet
--------------
Yet another method:
Draw a horizontal line through the top most edge of the figure. Do the same for the right-most side of the figure. The two lines meet in the top right corner. This will form a rectangle that is 21 ft tall and 24 ft wide.
The area of this big new rectangle is 21*24 = 504 sq ft.
However, we don't want all of this area. We'll kick out the rectangular piece that is 10 ft tall by 24-7 = 17 ft across (in the upper right corner). The area we want to kick out is 10*17 = 170 sq ft.
The actual area we want is 504 - 170 = 334 square feet
There are probably other methods you could use to find the area of this figure.

Last week Connor and his roommates ate 1 1/6 cartons of yogurt, and this week they ate 3 cartons. How much more yogurt did they eat this week compared to last week?
Step-by-step explanation:
last week they ate 1 1/6 = 6/6 + 1/7 = 7/6 cartons.
this week they ate 3 = 3×6/6 = 18/6 cartons.
so, how much more did they eat ?
it is not fully clear to me, if we need to find the absolute difference in cartons, or if we need the factor between both amounts (like "how many times did they eat more ?").
to be safe I give you both.
in absolute difference :
18/6 - 7/6 = 11/6 cartons = 1 5/6 cartons more.
as factor :
7/6 × x = 18/6
7x = 18
x = 18/7
they ate 18/7 = 2 4/7 times more

A convention center is in the shape of a rectangular pyramid with a height of 221 m. Its base measures 522 m by 500 m. Find the volume of the convention center. If necessary, round your answer to the nearest tenth.

57,681,000 m3
1,243 m3
Answer:
[tex]19\ 227\ 000\ m^{3}[/tex]
Step-by-step explanation:
The equation for volume of a rectangular prism is
[tex]V = \frac{hB}{3}[/tex]
[tex]B = lw[/tex]
V is volume
B is base
so if the base measures 522 multipled by 500
multiply length and width B = 522 • 500 = 261000
height is 221
V = [tex]\frac{hB}{3}[/tex]
Fill in variables V = [tex]\frac{221(251000)}{3}[/tex]
Multiply V = [tex]\frac{57681000}{3}[/tex]
Divide V = [tex]19\ 227\ 000\ m^{3}[/tex]

Compare the slope of the following equation and graph by determining which line is steeper.
A. The line represented by the equation has the same steepness as the line shown in the graph.
B. The line represented by the equation is steeper than the line shown in the graph.
C. The line shown in the graph is steeper than the line represented by the equation.
D. There is not enough information to determine the steepness of the lines.
Answer:
The equation is in the form y = mx, where m represents the slope.
So, the slope of the line represented by the equation is .
Use two points from the graph to determine the slope of the line shown on the graph.
The calculation shown below uses the points (0, 0) and (1, -2).
So, the slope of the graph is -2.
To determine which line is steeper, compare the absolute values of the slopes. The line whose absolute value of the slope is greater is the steeper line.
Therefore, the line shown in the graph is steeper than the line represented by the equation.
