Answer:
52.6 degrees
Step-by-step explanation:
tan^-1(72/55)
Angle of elevation is equals to 52°7'(approximately).
What is angle of elevation?
" Angle of elevation is the angle between the horizontal plane and line of sight from the point of observation."
Formula used
In a right angled triangle,
tanθ = ( opposite side) / adjacent side)
According to the question,
As shown in diagram
Height of the building (AB) = 72m
Distance between base of the building and point of observation
(BC)= 55m
Angle of elevation = θ
Substitute the value in the formula we have,
tanθ = AB / BC
= 72 / 55
⇒ θ = tan⁻¹ (72 /55)
= tan ⁻¹(1.3091)
= 52° 7' (approximately)
Hence, angle of elevation is equals to 52°7'(approximately).

Which equation represents the vertical line passing through (7,-3)?
A.
x = -3
B.
y = -3
C.
x = 7
D.
y = 7
Answer:
C. [tex]x=7[/tex]
Step-by-step explanation:
So we know that a vertical line is represented by [tex]x=[/tex] so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same [tex]x[/tex] coordinate. This means that the correct answer is [tex]x=7[/tex]

3. (x+2)(x+2)
Step-by-step explanation:
Solve for b: 3ab = -7
Since we are solving for b, you need to get it by itself. So you would divide both sides by 3a. That would leave b= -7/3a.

first person who answer correctly gets a brainllest The perimeter of a rectangle is 64 feet. The length of the rectangle is 3 times the width of the rectangle. If w represents the width of the rectangle, the equation that represents the perimeter is 2 (3 w) + 2 w = 64. Which shows the first step that should be taken to verify that the width of the rectangle is 8?
Answer:
2(3(8))+2(8)=64
Step-by-step explanation:
Here, w represents the width of the rectangle,
∵ length of the rectangle is 3 times the width of the rectangle,
So, length = 3w,
Since, the perimeter of a rectangle, P = 2(length + width)
= 2(w + 3w)
= 2w + 2(3w)
If P = 64 feet,
⇒ 2w +2(3w) = 64
⇒ 2w + 6w = 64
⇒ 8w = 64
⇒ w = 8
Verification :
P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet
Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64
Note : a solution obtain from an equation is verified by substituting the value in the equation.

Two siblings Edwin and Rhea are both going skiing but choose different payment plans. Edwin's plan charges $45 for rentals and $5.25 per lift up the mountain. Rhea's plan was a bundle where her entire day cost $108. Set up an inequality that models the number of trips, n, up the mountain for which Edwin will pay more than Rhea. Solve the inequality. Also, what is the greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea? Explain how you arrived at your answer.
Answer:
n>12
Step-by-step explanation
45+5.25n>108
-45 -45
5.25n > 63
then divide both sides by 5.25
n>12

The following figures are not drawn to scale but AB and CD are straight lines. Find x.
Answer: x = 30
Step-by-step explanation:
Since AB and CD are straight lines, vertical angles formed by them are congruent. Angle DOB is equal to angle AOC which is equal to 2x. Since you know that a straight angle is equal to 180 degrees, you can say :
2x + 90 + x = 180
3x + 90 = 180
3x = 90
x=30

Answer:
Okay so if your current scores are 93, 97, 89 and 81, You would have to score at least a 90. Even if you scored a 100%, the highest you would be able to make is a 92 average.
Step-by-step explanation:
Here's the thing about average, all you do is take all of the numbers, add them up, then divide them by the number of numbers there are.
For example, 93 + 97 + 89 + 81 = 360. There are 4 numbers so you would take 360 and divide it by 4 which gets you 90. 90 is your average.
To figure out the highest score you are able to get, take the highest score you can possibly score (100) and add it to the mix. 93 + 97 + 89 + 81 + 100 = 460. Now, there are 5 numbers. So you take 460 and divide it by 5 which will get you 92.

If Syn spends 15 minutes running, he burns 200 calories. How long will it take Syn to burn 150 calories?
Answer:
11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)
Step-by-step explanation:
create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.
The last step is to divide the calories burned by the corresponding ratio (40/3)
150/(40/3) = 11.25
and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.
ANSWER THIS FOR 11 POINTS, what are the slope and y intercept of the function?
Answer:
y intercept=4 and the slop is 1/3
Step-by-step explanation:
The y intercept is the point where the line intersects the y axis. As we can see the line is intecepting the y axis at point 0,4 or just 4. To find the slope from that point you need to go y places up or down and x places left or right-additionally the point has to be on that line. For example from point 0,4 which is our y-intercept if we go up 1 and over 3 to the right from that point then we get another point that's on the line.
-kinda hard to explain but hope this helps
Write the equation of a line in slope-intercept form with a slope of -1 and a y-
intercept of -1.
y = -x - 5
y = -5x - 1
y = -x-1
y= -5x -5
Answer:
y = -x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the slope and y intercept into the equation
y = mx + b
y = -x - 1 is the equation in slope intercept form
Answer:
y = -x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the slope and y intercept into the equation
y = mx + b
y = -x - 1 is the equation in slope intercept form
