Step-by-step explanation:
short hand radius = 4
distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)
distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2
long hand radius= 6
each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution
distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7
distance in 48hr = 37.7 x 48= 1809.6 (approx)
so sum of both= 1809.6 + 50.2 = 1859.8
Answer:
1910.12 cm
Step-by-step explanation:
2 days = 48 hrs = 2880 mins
One cycle of the short hand (4 cm) would be 12 hrs.
48/12 = 4 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 4 cm
2*pi*4 ≈ 25.13 cm (I only rounded to the hundredth, adjust as u need)
25.13 * 4 = 100.52 cm
One cycle of the long hand (6 cm) would be 60 mins (which is 1hr and two days would be 48hrs or 48 cycles. But let's keep this consistent).
2880/60 = 48 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 6 cm
2*pi*6 ≈ 37.70 cm (I only rounded to the hundredth, adjust as u need)
37.70 * 48 = 1809.6
100.52 + 1809.6 = 1910.12 cm

Find the area of the largest square contained by a circle of radius r = 1cm. Explain your answer and justify that it is correct. Hint: Use the pythagorean theorem.
Answer:
2 square cm
Step-by-step explanation:
Given :
A square is inscribed in a circle whose radius is r = 1 cm
Therefore, the diameter of the circle is 2 r = 2 x 1
= 2 cm.
So the diagonal of the square is 2r.
Using the Pythagoras theorem, we find each of the side of the triangle is [tex]$r \sqrt 2$[/tex].
Therefore, the area of the square is given by [tex]$\text{(side)}^2$[/tex]
= [tex]$(r\sqrt 2)^2$[/tex]
[tex]$= 2 r^2$[/tex]
[tex]$= 2 (1)^2$[/tex]
[tex]$=2 \ cm^2$[/tex]
Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.

A ladder rests against the side of a barn. The tip of the ladder reaches 20 feet up the wall and the base of the ladder reaches a point on the ground 12 feet from the wall. About how tall is the ladder?
A. 23 ft
B. 16 ft
C. 12 ft
D. 9 ft
Answer:
A - 23ft
Step-by-step explanation:
Pythagorean theorem: 12^2 + 20^2 = X^2.
X^2 = 544. X = sqrt(544) which is around 23ft

Luke and isabella make scale drawings.The scale from isabella's drawing is 6 m to 3 cm. The height of the fountain in isabella's drawing is 5 cm.The scale from the fountain to luke's drawing is 5m to 2cm. What is the height of the fountain in luke's drawing
Answer:
The answer is "[tex]2.5 \ cm[/tex]"
Step-by-step explanation:
While Luke is 5m to 2cm in size, it implies that every 2cm to Luke's drawing is 5m in real life. That real pond width must therefore be 5 m, given the fountain's width is 2 cm. As shown in the illustration, the step size for IsabelLa from the illustration to real life is [tex]\frac{6}{3} =2[/tex], which makes it simple to multiply any measure in the cm of her illustration by 2 to accomplish the exact size in m. So, in another direction around, they just have to divide the value by 2, instead of the divide from reality for drawing. So if the actual worth is 5m, it ought to be [tex]\frac{5}{2} = 2.5 \ cm[/tex] in its width.

Which expression is not equal to 1?
sin θ csc θ
cos θ sec θ
tan θ cot θ
sin θ cos θ
Answer:
sin θcos θ
hope it is helpful to you
Answer:
sin A cos A
Step-by-step explanation:
[ I don't know to type angle theta here so assume A as theta]
As , sin A= p/ h
cos A= b/ h
so,
sinA cosA = p/ h × b/h
= pb/ h^2 ( which is not equal to 1 )
Tip; you can easily verify other relations expressing trigonometric ratios in terms of p,b & h and further simplifying..

PLZS HELP THIS IS MY LAST QUESTION!!
Answer:
x = 30Step-by-step explanation:
According to figure,
54° + 3x+36° = 180° [Linear pair]
=> 3x + 90 = 180
=> 3x = 180 - 90
=> 3x = 90
[tex] = > x = \frac{90}{3} [/tex]
=> x = 30 (Ans)
Answer:
x=30
Step-by-step explanation:
cuz that line is 180 degrees and using algebra you can subtract 54 from both sides and get 126 then u have to subtract the 36 from both side to geth 90 and then divide the 3x to get x by itself which would leave u with 30 so x=30

Step-by-step explanation:

6x+?= 10x
6x−?= 2x
6x+?= 2x
6x−?= 10x
6x+?=- 10x
6x−?= x
6x+?= 0
6x−?= 6
6x+?= 10
6x−?= 4x - 10
Answer:
x=0
Step-by-step explanation:
Let's solve your equation step-by-step.
6x+x=10x
Step 1: Simplify both sides of the equation.
6x+x=10x
(6x+x)=10x(Combine Like Terms)
7x=10x
7x=10x
Step 2: Subtract 10x from both sides.
7x−10x=10x−10x
−3x=0
Step 3: Divide both sides by -3.
−3x/−3 = 0/−3
x=0
Now you can figure out which one is the best solution
