Ms. Aluma is 165 cm tall. She wants to find her height in meters. Divide her height in centimeters by 100 to find her height in meters.
Answers
1.65 meters...........
Unit conversion is a way of converting some common units into another without changing their real value. Ms. Aluma is using the correct option.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.
Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,
Height of Ms. Aluma = 165 cm
= 165/100 meters
= 1.65 meters
Hence, Ms. Aluma is using the correct option.

La ecuación de la recta que pasa por los puntos (2,-1) y (1,-5) es:

y= 4x-9
y= x-9

Answers
Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (2,-1) and (1,-5). So, the equation of the line is
[tex]y-(-1)=\dfrac{-5-(-1)}{1-2}(x-2)[/tex]
[tex]y+1=\dfrac{-5+1}{-1}(x-2)[/tex]
[tex]y+1=\dfrac{-4}{-1}(x-2)[/tex]
[tex]y+1=4(x-2)[/tex]
Using distributive property, we get
[tex]y+1=4(x)+4(-2)[/tex]
[tex]y+1=4x-8[/tex]
Subtract 1 from both sides.
[tex]y+1-1=4x-8-1[/tex]
[tex]y=4x-9[/tex]
Therefore, the correct option is B.

A tree struck by lightning broke at a point 12 feet above the ground. What was the height of the tree to the nearest tenth of a foot., 12 squared + 39 squared = ??
Answers
Answer:
52.8 feets
Step-by-step explanation:
From the diagram :
The height of tree woulb be :
Height above the ground (at breakpoint) + hypotenus
Hypotenus, h cab be obtained using Pythagoras rule :
h² = opp² + adj²
h² = 39² + 12²
h² = 1665
h = sqrt(1665)
h = 40.804 feets
Height of tree to the nearest tenth ;
40.804 feets + 12 feets
= 52.804 feets
= 52.8 feets

Answers
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]
finding d:
⇒tan 63 = [tex]\frac{d}{3.1}[/tex]
tan of 63 is 1.963
⇒ 1.963 = [tex]\frac{d}{3.1}[/tex]
multiply 3.1 on both sides
⇒ 1.963 x 3.1 = [tex]\frac{d}{3.1}[/tex] x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = [tex]\frac{7}{n}[/tex]
tan of 45 is 1
⇒ 1 = [tex]\frac{7}{n}[/tex]
multiply 7 on both sides:
⇒ 1 x 7 = [tex]\frac{7}{n}[/tex] x 7
7 = n
Answer:
D = 1.4, N =
Step-by-step explanation:
To get D you need to find the cosine of 63 degrees
Cosine(63) = D / 3.1
Multiply by 3.1 to isolate D :
3.1Cosine(63) = D
Put it into a calculator and you'll get 1.4.
Also, it's a 45-45-90 triangle so the 2 legs will be equal to each other.
Proof: To get N put you have to do the tangent of 45 degrees
Tan(45) = 7 / N
Now you can't to do this you have to multiply the both sides by N
N(tan(45)) = 7
Then divide both sides by (tan(45))
N = 7 / (tan(45)
Put it into the calculator and you'll get

The term with the highest degree is 3x^2
Followed by 4x
Then the constant 1
Adding according to the descending powers

Answers
Since the triangle is a right angled, to find one side we should use the pythagoras theorem.
The longed side of the triangle is called the hypotenuse.
In equation form: x² + y² = z²
Therefore: 12² + x² = 13²
114+x²= 169
x²= 169-114
x²= 55
x = 7.41
Therefore the length of AC = 7.41

The slope of a perpendicular line is the opposite reciprocal: meaning you change the sign (from - to + or from + to -) and flip the numerator and denominator (for example if your slope is -2, the perpendicular line’s slope would be 1/2).
First, find the slope of the graphed line. The two points you are given are (-1, 4) and (-2, 7). The formula for slope is m = (y2 - y1) / (x2 - x1) where m is the slope, and (x1, y1) and (x2, y2) are points. Plugging these points into the slope formula you get:
m = (7-4)/ (-2+1) = 3/-1 = -3.
The opposite reciprocal of -3 is 1/3, so the slope of the new line is 1/3.
In slope-intercept form, equations look like this: y = mx + b. M is your slope, and b is your y-intercept. You know the slope of the perpendicular line is 1/3 but still need to find the y intercept. To do this, first plug in your slope to the formula: y = 1/3x + b. Next, plug in (-6,5) to the equation for x and y and then solve for b.
5 = 1/3(-6) + b
5 = -2 + b
7 = b
Now you know what b is, you now have the full equation of the line: y = 1/3x + 7. You can now graph the line, too.
For #2, you are being asked to draw a line parallel to the graphed line which passes through the point (6,5)
The slope of a parallel line is the same as the slope of the original line.
The two points you are given are (-6,0) and (0,9). Plug these into the slope formula:
m = (9-0)/(0+6) = 9/6
The equation of the parallel line so far is y = 9/6x + b
Plug the point (6,5) into the equation to solve for b.
5 = 9/6(6) + b
5 = 9 + b
-4 = b
The equation is y = 9/6x -4. Now you just have to graph it.

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 12 cm, and the base has a
radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answers
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm
