4:43 or a quarter to 5
So there is 20 meters radius
If it takes 7 minutes to make a complete circle.
51.42857143 degrees a minute
t=0
Exactly 20 feet above the ground.
t = 7/4
40 feet above the ground
7/4 * 360/7 = 360/4 = 90 degrees
t = 14/4
9 o'clock position which is exactly 20 feet above the ground
t = 0. when t = 14/4, you are at exactly 14/4 * 360/7 = 180 degrees.
t = 21/4
Being 270 degrees
t = 28/4, you are back at the 3 o'clock position
28/4 equals 7 minutes because 7*4 = 28.
9 o'clock and 3 o'clock position
12 o'clock and 6 o'clock position
360/7 * t which is in minutes
20 plus the radius of the ferris wheel * the sin of the angle.
h = f(t) = 20 * (1 + sin(x)) where
x = 360/7 * t
t = minutes
h = the height you will be at.
when t = 0 which is 0 minutes, then:
x = 360/7 * t = 360/7 * 0 = 0 degrees
h = f(t) = 20 * (1 + sin(x)) becomes:
h = f(0) = 20 * (1 + sin(0))
since sin(0) = 0, this becomes:
h = f(t) = 20 * (1 + 0) = 20 * 1 = 20
you are 20 feet above the ground and you are at the 3 o'clock position
t = 7/4 which is 1.75 minutes
x = 360/7 * t = 360/7 * 7/4 = 360/4 = 90 degrees
h = f(t) = 20 * (1 + sin(t)) becomes
h = f(7/4) = 20 * (1 + sin(90))
since sin(90) = 1, this becomes:
h = f(7/4) = 20 * (1 + 1) = 20 * 2 = 40
you are 40 feet above the ground and you are at the 12 o'clock position
t = 14/4 which is 3.5 minutes, then:
x = 360/7 * t = 360/7 * 14/4 = 360*2/4 = 720/4 = 180 degrees
h = f(t) = 20 * (1 + sin(t)) becomes
h = f(14/4) = 20 * (1 + sin(180))
since sin(180) = 0, this becomes:
h = f(14/4) = 20 * (1 + 0) = 20 * 1 = 20
you are 20 feet above the ground and you are at the 9 o'clock position
when t = 21/4 which is 5.25 minutes, then:
x = 360/7 * t = 360/7 * 21/4 = 360*3/4 = 1080/4 = 270 degrees
h = f(t) = 20 * (1 + sin(t)) becomes
h = f(21/4) = 20 * (1 + sin(270))
since sin(270) = -1, this becomes:
h = f(14/4) = 20 * (1 - 1) = 20 * 0 = 0
you are 0 feet above the ground and you are at the 6 o'clock position of the ferris wheel which is at the bottom at ground level.
when t = 6 minutes, then:
x = 360/7 * 6 = 2160/7 = 308.5714286 degrees
h = f(t) = 20 * (1 + sin(t)) becomes
h = f(6) = 20 * (1 + sin(308.5714286))
since sin(308.5714286) = -.781831482, this becomes:
h = f(6) = 20 * (1 - .781831482) = 20 * .218168518 = 4.36337351
you are 4.36337351 feet above the ground and you are somewhere between the 4 o'clock and 5 o'clock position on the ferris wheel, much closer to the 5 o'clock position than the 4 o'clock position.
This would be roughly 4:43 or a quarter to 5. we are talking about the hour hand position.

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95 miles per hour. The eastbound train travels at 105 miles per hour. How long will it take for the two trains to be 440 miles apart?
Do not do any rounding.
[] hours
Answer:
2.2 hr
Step-by-step explanation:
Let t = time
95t = distance of westbound train
105t = distance of eastbound train
95t + 105t = 440
200t = 440
t = 2.2 hr.

At a movie theater 4 out of the first 10 customers bought popcorn. Based on this information, if 180 people go to the movie theater, how many would be expected to buy popcorn?
Answer:
72 people.
Step-by-step explanation:
4 out of 10 is 40%. Now apply that to 180. 40% of 180 is 72. Hope this helps.

eight less than five times a number is greater than 6
Answer:
8 - 5x > 6
Step-by-step explanation:
Answer is in the problem:
eight = 8
less than = minus ( - )
five times a number = 5x (dont know the number so we put down "x")
is greater than 6 = > 6
does that make sense?

Please help me Sally hiked 6 tenths of a 3.6 mile trail. How many miles did Sally have left to hike?
Answer:Sally hiked 2.16 miles
Step-by-step explanation:
Sally hiked 6 tenths of a 3.6 mile trail.
6 tenths means 6/10
Therefore, Sally hiked 6/10 x 3.6 mile= 2.16 miles
Is this unbiased or biased?
The Bernal leadership class is going to sell spirit t-shirts for students and needs to order a color that most students would like to wear, so they ask every fourth student entering the school about their favorite t-shirt color to make a decision about all Bernal students.
Biased, because some students may not like that color, and thus going off of the most popular opinion is only supporting the most popular color. Adding onto that, not every student even gets to vote since it is only every 4th student.

Ryan and Sheila are preparing to get married. Sheila has a car payment of $297.00 per month, which is 9% of her monthly income. After they are married, Sheila knows that her car payment will only be 5% of their combined monthly income. How much money does Ryan make per month?
Answer:
$2640
Step-by-step explanation:
Sheila's car payment is 9% of her total income.
let i = total income
this equation can be used to represent the information :
9% x i = $297
to determine i, divide both sides of the equation by 9%
$297 / 0.09 = $3300
After the marriage, the car payment which is 3300 would be 5% of the combined income.
let c = combined income
5% x c = $297
c = $297 / 0.05 = $5940
Ryan's income = combined income - Sheila's income
$5940 - $3300 = $2640

Write a set of parametric equations for the equation x = 3y - 2 given that t= x + 3
Answer:
i hope you meant "y" instead of "t" because that would make so much more sense. all you have to do with this is replace "y" in the equation with "x + 3" (this makes the equation x = 3[x + 3] - 2). now, you multiply and combine the like-terms (making x = 3x + 7). you now continue by subtracting 3x from both sides of the equation to make -2x = 7 and dividing to make x = -3.5
Step-by-step explanation:
x = 3(x + 3) - 2
x = 3x + 9 - 2
x = 3x + 7
-2x = 7
x = -3.5

Answer:
blank 1: 24
Step-by-step explanation:
According to Pythagoras' Theorem, in a right-angled triangle,
(side 1)² +(side 2)²= (hypotenuse)²
Applying Pythagoras' Theorem,
x² +18²= 30²
x² +324= 900
x²= 900 -324 (-324 on both sides)
x²= 576
[tex]x = \sqrt{576} [/tex]
x= 24 ft
Work out the lengths of side a and side b 8cm and 5 cm 1 triangle 17cm and 12 cm on the other triangle pythagoras
Answer:
a = 9.4 cm
b = 12.0 cm
Step-by-step explanation:
Check the image uploaded for diagram;
For the first diagram, side length a is calculated as follows;
a² = 8² + 5²
a² = 64 + 25
a² = 89
a = √89
a = 9.4 cm ( approximated to 1 decimal place)
For the second diagram, side length b is calculated as follows;
b² = 17² - 12²
b² = 145
b = √145
b = 12.0 cm (approximated to 1 decimal place)

I bought 5 crates of apples. Each crate contains 10 apples. I want to display the apples on 5 shelves. How many apples will be on each shelf?
Answer:
10
Step-by-step explanation:
I bought 5 crates of apples
Each crate contains 10 apples
I want to exhibit the appleonin 5 shelves
Therefore the apples on each shelve can be calculated as follows
Total apples= 50
= 50/5
= 10
Hence there would be 10 apples on each shelf

Answer:
27) 4.2
28) D
Step-by-step explanation:
Answer:
27. A 4.2ft
28. D
Step-by-step explanation:
27. Since this is a right triangle, we can use a^2 + b^2 = c^2
3.1^2 + b^2 = 5.2
b = sqrt(5.2^2 - 3.1^2)
b = 4.2ft A
28. sqrt(10^2 + 50^2) does not equat 54, this is not a right triangle.
