Answer:
8.38 radians
Step-by-step explanation:
correct on edge 2021
The angular velocity of the Ferris wheel is 8.38 radians/minute.
What is angular velocity?"The angular velocity is the time rate at which an object rotates or revolves about an axis."
It takes 45 seconds for her chair to complete a full revolution.
Therefore, in terms of revolution per minute, the speed is
= 60/45 revolutions/minute
= 4/3 revolutions/minute.
We know, 1 revolutions = 2π radian
Therefore, 4/3 revolutions/minute
= (4/3) × 2π radians/minute
= 8.38 radians/minute
Hence, the angular velocity is 8.38 radians/minute.

Jada, Diego, and Elena each use the same spinner that has 4 sections marked A, B, C , and D. Which estimate do you think is most accurate? Jada says, "The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times. " Diego says, "The probability of spinning B is 20% because I spun 5 times, and it landed on B twice." Elena says, "The probability of spinning B is 2/7 because I spun 7 times, and it landed on B twice."
Answer:
The correct option is;
"The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times."
Step-by-step explanation:
Out of the three trials, Jada had the most number of trials (10) and therefore, the highest precision value and the best estimate out of the three persons that did the trials
The more the sample or trials increase, the more the precision increases as the number of trial comparisons and testing increases.
The increased trials give more information, resulting in a more precise estimate. It also increases the confidence in the result and reduces the amount of uncertainty and increases precision of the results.

Graph the line with the equation y = x + 6.
Answer:
Hi there!
Your answer is:
Based off the equation we know that the slope is 1 and the y intercept is 6. We know that slope is rise/run so it goes UP one unit for every unit it goes RIGHT! We must start at the point (0,6) because that is the y intercept

Answer:
12 minutes
Step-by-step explanation:
Given the question :
how much time could Robert save on a 60 mile trip if he drove at 70 mph rather than at 50 mph?
Time taken to cover 60 miles at a speed of 50 miles per hour
Recall :
Time taken = distance / speed
Hence, at Speed = 50 mph
Time taken = 60/50
Time taken = 1.2 hours = (1.2 * 60) = 72 minutes
At speed = 70mph
Time taken = 70/50
Time taken = 1.4 hours = (1.4 * 60) = 84 minutes
Time saved :
(84 - 72) = 12 minutes

Can I please get help with the Answer
Answer:
56
Step-by-step explanation:
Answer:
B = 56
Step-by-step explanation:
A + B = 90 degrees
(6x - 8) + (5x + 21) = 90
6x - 8 + 5x + 21 = 90
(6x + 5x) + (-8 + 21) = 90
11x + 13 = 90
11x + 13 - 13 = 90 - 13
11x = 77
11x/11 = 77/11
x = 7
Plug into (5x + 21).
5(7) + 21 =
35 + 21 = 56
B = 56

For questions 18-20, if l \\ m, find the values of x and y
Answer:
Step-by-step explanation:
18). l║m and a transverse is intersecting these lines.
(11y - 32)° = (6x + 7)° [Vertical angles]
-6x + 11y = 39 -------(1)
(3x - 16)° + (6x + 7)°= 180° [Same side exterior angles]
9x - 9 = 180
9x = 189
x = 21
Now substitute the value of x in the equation (1)
-6(21) + 11y = 39
11y = 39 + 126
y = 15
19). l║m and a transversal is intersecting these lines.
(8x - 14)° + (5y + 16)° = 180° [Linear pair of angles]
8x + 5y = 178 --------(1)
(8x - 14)° = (5x + 34)° [Alternate exterior angles]
8x - 5x = 48
3x = 48
x = 16
From equation (1)
8(16) + 5y = 178
128 + 5y = 178
5y = 178 - 128
y = 10
20). From the figure attached,
m∠CAB = (5y - 23)°
Since sum of interior angles of a triangle is 180°
m∠CAB + m∠ACB + m∠ABC = 180°
(5y - 23)° + (2x + 13)° + (47)° = 180°
2x + 5y = 143 ------(1)
(5y - 23)° = 3x°
3x - 5y = -23 -----(2)
Equation (1) + Equation (2)
(2x + 5y) + (3x - 5y) = 143 - 23
5x = 120
x = 24
From equation (1)
2(24) + 5y = 143
48 + 5y = 143
5y = 95
y = 19

A pool estimate that 43% of likely voters are in favor of additional restrictions on teen drivers the Poll has a margin of error of plus or minus 4%. Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Estimated number of voters in favor of additional restriction = 43%
Margin of Error = ±4%
Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:
Minimum percentage of voters = 4% lesser than the estimated number of voters
Maximum percentage of voters = 4% greater than the estimated number of voters
Let number of voters = v
|v - 43%| = ±4%
v = - 4% + 43% = 39% = minimum percentage
v = +4% + 43% = 47% = maximum percentage
39% ≤ v ≤ 47%

Suppose that the total annual consumption of salmon in a certain country is given by y = 5.59x + 837.5 and that the total annual consumption of tuna in this country is given by y = 1.49x + 878.5, where consumption is measured in millions of pounds and x is the number of years since 2010. When consumption of salmon reaches consumption of tuna, what is the annual consumption of salmon? 897.87 million pounds 890.42 million pounds 894.89 million pounds 893.4 million pounds
Answer:
893.4 million pounds
Step-by-step explanation:
Total annual consumption of salmon is given by [tex]y=5.59x+837.5[/tex]
Total annual consumption of tuna is given by [tex]y=1.49x+878.5[/tex]
As consumption of salmon is equal to the consumption of tuna,
[tex]5.59x+837.5=1.49x+878.5\\5.59x-1.49x=878.5-837.5\\4.1x=41\\x=\frac{41}{4.1}\\ x=10[/tex]
Put [tex]x=10[/tex] in [tex]y=5.59x+837.5[/tex] to find total annual consumption of salmon.
Therefore,
Total annual consumption of salmon = [tex]5.59(10)+837.5=893.4[/tex] million pounds
