A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform. How long is the zip line? *
Answers
Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.

A school needs $5,000 to buy new books for the library. So far, the school has raised 75% of the money they need. How much money has the school raised so far?
NO LINKS
Answers
explanation:
To get a percentage there’s many to calculated it. Personally, i multiply the total amount by the decimal. In this case the total amount would be 5000 dlls, which equals to 100%. The question is asking for 75%, so .75; because 100 is 1 whole.
So to get things answer you multiply 5000x.75 which equals to 3750 dlls.
the equation of the line that is perpendicular to the line with equation y=-2x-1 and passes through the point (1, -2) is?
Answers
Answer:
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]
Step-by-step explanation:
Hi there!
Note that:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)1) Determine the slope (m)
When we look at the given line, [tex]y=-2x-1[/tex], we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of [tex]\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (1,-2)
[tex]-2=\frac{1}{2}(1)+b\\-2=\frac{1}{2}+b[/tex]
Subtract 1/2 from both sides
[tex]-2-\frac{1}{2}=\frac{1}{2}+b-\frac{1}{2}\\-\frac{5}{2} = b[/tex]
Therefore, the y-intercept of the line is [tex]-\frac{5}{2}[/tex]. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]

Luz tiene 240 globos blancos y 360 celestes y los usará para decorar un salón. Si los ubica en grupos de manera que cada uno tenga la misma cantidad de globos de cada color, a) ¿Cuántos grupos puede hacer como máximo? b) ¿Cuántos globos de cada color tendrá cada grupo?
Answers
Answer:
a) 120
b) 2 globos blancos por grupo
3 globos celestes por grupo
Step-by-step explanation:
Resolvemos usando el máximo factor común
a) ¿Cuántos grupos puede formar como máximo?
Los factores de 240 son: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
Los factores de 360 son: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
Entonces el máximo común denominador es 120.
b) ¿Cuántos globos de cada color tendrá cada grupo?
Para cada grupo,
Por los globos blancos
= 240/120 = 2 globos blancos por grupo
Por el celeste
= 360/120 = 3 globos celestes por grupo
Hi! Does anyone know the answer to this question? I’m bad at geometry and I’m struggling to get the answer. Please help!
Answers
The diagram is shown below
Point A is located at (0,8). It's exactly 8 units away from the origin (0,0).
Let's say point C is at the origin. That would mean segment AC is 8 units long.
Divide segment AC into four equal parts. Each part is 8/4 = 2 units long.
Move to point A(0,8) and then drop down 2 units to arrive at (0,6). Use your straightedge to draw a horizontal line from (0,6) until you reach the diagonal line AB. Mark point P on the diagonal line. Refer to the diagram to see what I mean.
Now move back to (0,6) and drop down another 2 units to get to (0,4). Draw a horizontal line through this point until you reach the diagonal line. Mark point Q on the diagonal line.
Repeat this process until you get to the origin. You'll find that segment AB has been cut into four equal parts. This works because we've divided AC into four equal parts, which helps divide AB into four equal parts. The two concepts are directly connected. More specifically, we're using similar triangles to help do the subdivisions here.
So this trick is very handy if you have a diagonal road you're trying to divide into four (or any number) equal parts. It's also useful if you are dealing with fencing and you want to divide which if your friends will take care of which portions of the fence. Those are just two examples of real world applications.

At a game show, there are 8 people (including you and your friend) in the front row. The host randomly chooses 3 people from the front row to be contestants. The order in which they are chosen does not matter. There are ^8C^3 = 56 total ways to choose the 3 contestants. What is the probability that you and your friend are both chosen?
Answers
Answer:
6 / 56
Step-by-step explanation:
Total Number of people = 8
Number of people to be chosen = 3
Hence, total possible outcomes = 8C3 (since order does not matter)
Recall:
nCr = n! ÷ (n-r)!r!
8C3 = 8! ÷ 5!3!
8C3 = (8*7*6) / (3*2*1) = 56
Required outcome :
I and my friend plus one other person
I and my friend = 2C2
1 person from the remaining 6 = 6C1
Required outcome :
2C2 * 6C1 = 1 * 6 = 6
P = required outcome / Total possible outcomes
= 6 / 56

6/56

6y-5=11 what’s the awnser?
Answers
Step-by-step explanation:
Simplifying
6y + -5 = 11
Reorder the terms:
-5 + 6y = 11
Solving
-5 + 6y = 11
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 6y = 11 + 5
Combine like terms: -5 + 5 = 0
0 + 6y = 11 + 5
6y = 11 + 5
Combine like terms: 11 + 5 = 16
6y = 16
Divide each side by '6'.
y = 2.666666667
Simplifying
y = 2.666666667
Answer: I think Y = 2.7! :)

Step-by-step explanation:
A right triangle has one angle of 90.
If you add up all the angles ;
19+12+16= 47
It equals 47 so this is not a right triangle.
If it it is less than 90, it is an acute angle.
Therefore this angle is an acute triangle.
