Answer:
[tex]L=480\ kg-m^2/s[/tex]
Step-by-step explanation:
Given that,
Mass of a person, m = 80 kg
The distance from the centre of the platform, r = 2 m
The tangential speed of the platform, v = 3 m/s
We need to find the angular momentum of the person. The formula for the angular momentum is given by :
[tex]L=mvr\\\\L=80\times 3\times 2\\\\L=480\ kg-m^2/s[/tex]
So, the required angular momentum is equal to [tex]480\ kg-m^2/s[/tex].
Answer:
Tangential speed is 0.68 m/s
Explanation:
It is given that,
Mass of the beetle, m = 0.023 kg
It is placed at a distance of 0.15 m from the center of record i.e. r = 0.15 m.
If it takes 0.070 n of force to keep the beetle moving in a circle on the record i.e. centripetal force acting on it is, F = 0.070 N
We have to find the tangential speed of the beetle. The formula for centripetal force is given by :
v is tangential speed
v = 0.675 m/s
or
v = 0.68 m/s
Hence, the correct option for tangential speed is (A).

Sara needs one third of a yard of ribbon to make a bow. She has 10 yards of ribbon. How many bows can she make?
Answer:
30 bows
Step-by-step explanation:
To find how many bows she can make, divide 10 by 1/3
10 / (1/3)
= 30
So, Sara can make 30 bows
Answer:
30
Step-by-step explanation:
If she needs just one third then she can make three ribbons out of a yard. so you multiply 3 by the number of yards she has so:
3 x 10 = 30
what’s the equation for this graph?
Answer:
y=-3x+2
Step-by-step explanation:
as x goes up on y goes down 3
slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2

Find the missing length of the triangle.
Answer:
35/3yd
Step-by-step explanation:
The width of a rectangle is the length minus 6 units the area of the rectangle is 27 units
Answer:
length = 9 units
Step-by-step explanation:
l = length
n - 6 = width
A = n(n - 6)
A = n² - 6n
27 = n² - 6n
n² - 6n - 27 = 0
(n + 3)(n - 9) = 0
n = -3, n = 9
length must be 9 because it cannot be a negative value

Aniya went bowling and spent $5 to rent bowling shoes and paid $6.75 per game bowled. If Aniya spent $25.25 total, answer the following questions
A Write an equation
B Solve the equation
C Find the cost for 10 games
Answer:
Aniya only needs to pay for her shoes once so $5 is your B or y-intercept. $6.75 is your slope. So your equation in y-intercept form will be y = $6.75x + $5. Now plug in the numbers to find how many games she played if she spent $25.25.
Equation: y = $6.75x + $5
Answer for B:
($25.25 - $5) / $6.75
The answer: She played three games.
Answer for C:
y = $6.75 * 10 + $5
The answer: She paid $72.5 if she bought 10 games and rented a pair of shoes.
Mr. Charles needs to have at least 11 students sign up for homework help in order to use the computer lab. The inequality h ≥ 11 represents the number of students h who must sign up. Select possible solutions of the inequality. Mark all that apply. A 10 B 14 C 8 D 6 E 12 F 11
Answer: Required solution: B. 14, E. 12 , F. 11.
Step-by-step explanation:
Requirement: at least 11 students sign up for homework help in order to use the computer lab.
Given inequality: h ≥ 11 that represents the number of students h who must sign up.
i.e. Solution must be 11 or a number greater than 11.
i.e. Solution can be 11, 12, 13, 14 , ...
Hence, the correct options are B. 14, E. 12 , F. 11.

Find the M<6 if m<2 = 75
Answer:
75
Step-by-step explanation:
angle 2 and angle 6 are corresponding angles, because the lines are parallel and cut by a transversal, corresponding angles are congruent, thus if angle 2 is 75 degrees then angle 6 is 75 degrees

Answer:
7/8 ≈ .9
y = -3x/4 + 4.75
x = 9 ⅓
Rotation
Step-by-step explanation:
1.) 7/8 = 0.875 The hundredths place is 7, which means we round up to 0.9
2.) Isolate the y on the left. Then divide both sides by 4
3.) Subtract 7 from both sides, then divide both sides by 3
Rotation turns around a point Reflection flips across a line.

Ryan buys some jumpers to sell on a stall. He spends £130 buying 80 jumpers. He sells 75% of the jumpers for £9 each. He then puts the rest of the jumpers on a Buy one get one half price offer. He manages to sell half the remaining jumpers using this offer. How much profit does Ryan make?
Answer:
£477.5
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Total jumper bought = 80
Total spends = £130
Now, first sell 75% of jumper for £9 each, then
75% × 80 = 60
So, 60 × £9 = £540
Remaining jumper = 80 - 60 = 20
Selling half of remaining, 20÷ 2 = 10
Selling 10 jumper = (5 × £9) + (5 × £4.5 ) ( buy one get one half price)
Income of 10 = £45 + £22.5 = £67.5
So, total income by selling 70 jumpers = £540 + £67.5 = £607.5
Hence, Profit = £607.5 - £130
= £477.5

Let's call the missing side ? as shown in the problem.
Now set up a equation where everything adds up to 28x+11
?+8x+2+8x+2+5x+12=28x+11
?+21x+16=28x+11
?=28x-21x+11-16
?=7x-5
So 7x-5 is the missing side!
